"As simple as Trello but as feature-rich as Jira" is how the Leantime team frames its goals-focused project management system for non-project managers - built from the ground up with ADHD, autism, and dyslexia in mind, with behavioral science shaping customizable dashboards, time blocking, low-cognitive-load prioritization, and Kanban, list, table, Gantt, and calendar views so each person works the way their brain does. The PHP application (AGPL, Laravel Blade frontend) connects strategy to execution: tasks with unlimited subtasks and dependencies roll up into milestones on a timeline, sprints and retrospectives handle iteration, and strategy-level blueprint boards - Lean Canvas, SWOT, risk analysis, goal and metric tracking - keep the "why" attached to the work. Knowledge lives alongside: wikis and docs, idea boards, comments on everything, file storage on S3 or local disk, even screen and webcam recording. Time tracking with timesheets supports estimation and client billing. Admin features are serious for an OSS tool: per-project permissions, two-factor auth, LDAP and OIDC single sign-on, Slack, Mattermost, and Discord integrations, a plugin system, and an expanding API that now powers a mobile app. Recent releases added multi-collaborator task assignment and low-vision accessibility improvements. Available in 20+ languages.

Recognized by the CNCF Landscape in the AI Agent – Workflow Orchestration category alongside Dify and Temporal, Astron Agent is iFLYTEK's fully open-source platform for building, deploying, and managing enterprise multi-agent systems — backed by 8,900+ GitHub stars and the production infrastructure behind one of China's largest AI companies. Unlike pip-install frameworks such as LangGraph, CrewAI, or AutoGen, Astron Agent ships as a complete microservices platform spanning 10+ services across Java, Python, Go, and TypeScript: a ReactFlow-based visual workflow builder for low-code agent orchestration, native integration with the Model Context Protocol (MCP) for tool calling, a built-in model management layer supporting iFLYTEK Spark, OpenAI, Anthropic, and on-premises MaaS deployments, and a multi-tenant Go authentication service powered by Casdoor. The standout differentiator is native RPA integration via the companion astron-rpa project (7,200+ stars), providing 300+ pre-built automation capabilities spanning browser, Office document, and enterprise system interaction — enabling agents to execute physical UI actions rather than only API calls. Infrastructure includes PostgreSQL for multi-tenant data isolation, MySQL for application metadata, Kafka for event streaming, Redis for caching, and MinIO for object storage, all orchestrated through Docker Compose with explicit health checks and dependency chains or production Kubernetes Helm charts.

farmOS is the record book, map, and planning board for a working farm, replacing the notebook, the spreadsheet, and the whiteboard with one web app the whole crew can check from the field. The dashboard opens on a map of your land, so you click a field, a barn, or a pasture to reach every record tied to that place. Assets are the things you manage, from fields and animals to equipment and plantings, and Logs are everything that happens to them: seedings, harvests, treatments, movements, and observations, each with dates, notes, and photos. Quantities attach real numbers to those logs, such as kilograms harvested, litres applied, or hours worked, turning daily notes into yields and input costs you can compare across seasons. Quick forms make common entries fast on a phone, and upcoming or late tasks on the dashboard keep pending work from being forgotten. Plans group assets and logs around a purpose such as a grazing rotation or a season of crop production, while reports summarize the records for analysis. Crew members get their own accounts with permissions, records stay private by default, and an API plus add-on modules connect sensors and other farm tools. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.

Ever Gauzy consolidates ERP invoicing, CRM sales pipelines, HRM employee records, applicant tracking, and project management into one full-stack TypeScript platform, eliminating the need to stitch together five separate SaaS subscriptions. Over 4,300 GitHub stars and 3,800+ releases back a CQRS architecture that separates command and query responsibilities across modules for invoices, expenses, payments, inventory, contacts, leads, deals, employee onboarding, candidate interviews, hiring workflows, sprints, goals, and KPI tracking. Time tracking captures hours via web timer, Electron desktop timer with activity monitoring and automatic screenshot capture, or browser extension, with timesheet submission and approval workflows supporting billable hour classification across Hubstaff and Upwork integrations. The multi-tenant architecture provides automatic tenant scoping with role-based permissions, while dual ORM support through TypeORM and MikroORM with Knex query builder ensures database flexibility across PostgreSQL, MySQL, and MariaDB. REST APIs documented with OpenAPI and Swagger expose every module for headless operation, complemented by an MCP server offering 323 tools for AI assistant integration. The Angular 19 dashboard provides dark, light, corporate, and material themes with i18n across 10 languages via Crowdin. Supports Docker, Kubernetes, Terraform, and Pulumi deployment with Redis caching and OpenSearch full-text indexing. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

One front-end server can run your entire cloud: OpenNebula orchestrates KVM virtual machines and LXC containers across clusters of hosts, presenting everything through the FireEdge Sunstone web interface and a full API. Operators define VM templates once and instantiate them anywhere, attaching disks and networks, taking snapshots, scheduling actions, and opening remote consoles through Guacamole without leaving the browser. The OneDRS distributed resource scheduler reads historical and real-time metrics to predict demand spikes and migrate workloads before contention bites, with customizable policies and automation levels. GPU passthrough and PCI device hotplugging serve AI and accelerator workloads, while OVA import through the oneswap command ingests virtual machines exported from VMware vCenter for re-virtualization projects. Edge Clusters deploy on demand on premises or at remote providers, extending the same management model to hybrid and distributed sites without a separate stack. The 7.4 Helix release redesigns Sunstone with a slide-in side drawer and richer resource visualizations, and brings OneKS managed Kubernetes plus LVM storage to the Community Edition. Ceph and LVM datastores, incremental backups, cluster-level and generic quotas for resources like vGPUs, and OneFlow service orchestration for multi-VM applications round out daily operations. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

InvenTree is an inventory management system for electronics manufacturers, makerspaces, and small-to-medium businesses. The hierarchical part categorization system organizes components into unlimited nested categories, while stock items tracked across cascading locations and sub-locations provide instant visibility into current inventory levels, with optional serial number tracking for individual item traceability and acceptance testing. Intelligent BOM management calculates sub-part requirements, validates availability against current stock, supports multi-format BOM upload including KiCad integration, and generates detailed bills of materials with full database enrichment. Build orders consume BOM-allocated stock to produce assembled parts with step-by-step work order tracking, while purchase orders manage supplier relationships with pricing history, lead times, and automatic stock receipt processing. The modern React frontend built with Mantine, TanStack Query, and Zustand provides responsive data tables, tree-select navigation, a preview drawer, and a snippet editor. The extensible plugin system supports 19 mixin types including BarcodeMixin for scanner integration, LabelPrintingMixin for Zebra and Brother printers, AppMixin for custom database tables, and ScheduleMixin for periodic background tasks. Companion mobile apps on Android and iOS provide barcode scanning and stock operations in the warehouse. Docker Compose deploys with PostgreSQL, MySQL, or MariaDB backends behind any reverse proxy. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Quote to cash in one web application - create quotes, convert them to invoices, record payments, track customers: iDURAR is an open-source ERP and CRM platform for small and medium-sized businesses. Built on the MERN stack (MongoDB, Express, React, Node.js) with Ant Design components and Redux state management, it presents a clean SaaS-style interface that needs little onboarding. Core modules cover invoice management with PDF generation and email delivery, payment recording against invoices, quote and proforma handling, customer records, and accounting views over the resulting data. Multi-currency support and localization make it usable for internationally operating teams. Because the whole stack is JavaScript with an API-first backend, extending it - custom fields, new modules, integrations - is approachable for any Node/React developer rather than requiring a specialist ERP skill set. Deployment is straightforward via Docker with a MongoDB instance. Licensed under AGPL-3.0 with free commercial use; a hosted enterprise version exists but the self-hosted edition is fully functional.

"Forget about bouncers" became a real sentence because of The Lounge: a Node.js web IRC client that holds persistent connections to your networks 24/7, logging everything while you sleep, so closing the browser tab never means missing a message or losing your place in a channel. Open it again from any device - desktop, phone, tablet - and you resume exactly where you left off, with full history synchronized. Because it combines bouncer and client in one process, the experience feels like a modern chat app rather than 1990s infrastructure: push notifications for highlights and private messages (with self-generated VAPID keys, so even Web Push needs no third-party service), automatic link previews, inline file and image uploads, and full IRCv3 protocol support. It installs as a progressive web app from any modern browser, so phones get a native-feel client without an app store. Multi-user support means one instance serves your whole team or community, each user with their own networks and history, and LDAP integration ties into existing authentication. A public mode alternatively serves as an open, registration-free web chat for events or support channels. MIT-licensed, born as a fork of Shout, and a fixture of self-hosting stacks since.

Transform complex code repositories into searchable, interactive wikis with DeepWiki, an automated documentation platform that maps architectural relationships and provides instant answers to technical questions about any codebase. Software engineers can submit public or private repositories from GitHub, GitLab, or Bitbucket to generate comprehensive project overviews, component breakdowns, and interactive Mermaid diagrams illustrating data pipelines and class hierarchies. The built-in Ask interface allows developers to query system logic using retrieval-augmented answers grounded directly in repository source files. Teams can trigger iterative deep research sessions that perform multi-step codebase investigations to explain intricate execution paths, uncover hidden dependencies, and summarize complex algorithms across hundreds of files. Interactive Codemap tours provide guided walkthroughs of critical entry points, letting reviewers inspect synchronized code viewer panels with exact line references while onboarding to unfamiliar services. Developers can export complete wiki structures for offline sharing, customize documentation depth from high-level summaries to granular module analyses, and connect local or cloud model endpoints to process sensitive internal code securely. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Garnet is Microsoft Research's cache-store built on .NET that speaks the Redis RESP wire protocol while delivering up to 10x higher throughput and 4x lower tail latency than comparable alternatives on identical hardware. The Tsavorite storage engine provides a cache-friendly, shared-memory architecture scaling linearly across CPU cores, supporting both in-memory operation and tiered storage across local SSDs and Azure Storage for datasets exceeding available RAM. Cluster mode enables sharded deployments with replication, dynamic key migration for live rebalancing, non-blocking checkpointing, and automatic failover using standard Redis cluster commands. The RESP implementation covers raw strings, sorted sets, lists, hashes, sets, bitmaps, HyperLogLog, streams, pub/sub, Lua scripting, and client-side transactions, allowing StackExchange.Redis, Jedis, redis-py, and other Redis clients to connect without modification. C#-based extensibility lets developers define custom commands and new data types as server-side stored procedures, compiled and loaded at runtime without restarting the server. TLS encryption, ACL-based access control, and operation logging complete the production feature set. Deployed across Microsoft services including Windows & Web Experiences, Azure Resource Manager, and Azure Resource Graph. Nearly 12,000 GitHub stars. MIT licensed.

Edict is a multi-agent orchestrator that runs every AI request through a court-style chain: a crown prince agent triages it, a planning department drafts the work, a review department can veto the plan, and specialist ministries execute what survives. Casual chat gets a direct reply, while real commands become kanban tickets whose titles are scrubbed of file paths and metadata. A vetoed plan returns for rework; an approved one is dispatched in parallel to ministries for finance, documentation, engineering, compliance, infrastructure, and HR. Commands arrive through Feishu, Telegram, or Signal channels configured in OpenClaw. The dashboard shows cards by state with heartbeat badges and stop, cancel, and resume controls, plus a department monitor and a memorial archive that turns finished work into five-phase timelines you can copy as Markdown. Nine edict templates add parameter forms and cost estimates, an officials panel ranks agents by merit score while tracking token spend, and per-agent model switching restarts the gateway in about five seconds. Agent thinking, tool calls, and results stream live. A permission matrix limits who may message whom, illegal state jumps are rejected, and every transition lands in an audit log. Worked examples cover competitive analysis, code review, and weekly reports. Dashboard login protects the console, and a systemd unit keeps it running across reboots. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Deployment decoupled from release: Unleash, the most popular open-source feature management platform on GitHub, is a Node.js server backed by PostgreSQL. Ship code dark, then control who sees it through activation strategies: gradual percentage rollouts, targeting by user ID, IP, hostname, or application name, custom constraints against your own context fields, and scheduled or time-limited releases. Strategies stack - a flag activates if any strategy matches - and strategy variants layer A/B versions on top of the on/off decision. Each flag carries per-environment configurations, so a feature can run at 100% in staging while canarying at 5% in production. Backend SDKs (Node.js, Java, Go, Python, Ruby, .NET, PHP, Rust, and more) fetch configuration and evaluate flags locally, so a flag check adds zero network latency to request paths; frontend SDKs for React, Vue, Svelte, iOS, Android, and Flutter evaluate through a proxy layer. Flag hygiene is built in: flags are typed (release, experiment, operational, kill-switch, permission) with expected lifetimes, and Unleash marks overdue flags as potentially stale and surfaces unknown flags your SDKs request but that don't exist. Self-hosting via Docker keeps flag data, targeting rules, and evaluation infrastructure entirely on your side.

Livebook is an interactive notebook for Elixir where you write code alongside rich Markdown prose, execute it cell by cell with reactive dependency tracking, and deploy finished notebooks as standalone web applications with a single click. Nearly 6,000 GitHub stars reflect the Elixir core team's investment in a platform where code cells run on demand alongside Mermaid diagrams and KaTeX mathematical formulas. The Kino visualization library renders Vega-Lite charts, interactive data tables with sorting and pagination, Leaflet maps, and Mermaid diagrams directly within notebook output cells, while custom Kino components enable building interactive controls with sliders, text inputs, and buttons that feed values back into running code. Smart cells abstract high-level tasks into configurable UI widgets: query PostgreSQL, MySQL, SQLite, and BigQuery databases, train machine learning models with Axon, plot charts, and build map visualizations without writing boilerplate code. Real-time collaboration lets multiple users edit the same notebook simultaneously with cursor presence indicators and synchronized cell evaluation. Notebooks are stored as .livemd files, a Markdown-compatible format that renders cleanly on GitHub and integrates with standard version control workflows. Custom runtimes connect Livebook to existing Elixir applications for live introspection and documentation of running systems. The Docker image at ghcr.io/livebook-dev/livebook exposes ports 8080 and 8081 with password or token authentication.

Every Terraform change becomes a pull request with Atlantis, which runs the plan on your server, posts the output for review, and applies only the exact change reviewers approved. Open a pull request that touches Terraform code and Atlantis automatically runs terraform plan, posting the full output as a comment and a commit status your reviewers can inspect line by line. When the change looks right, a teammate comments atlantis apply and Atlantis executes the exact plan that was reviewed, then reports the result back on the same pull request. Each directory and workspace is locked while a pull request is open, preventing two changes from applying out of order, and locks can be inspected or discarded from the web interface. Apply requirements let you demand an approved review or a mergeable branch before anything runs, and optional policy checks evaluate plans against your rules before they can proceed. Repositories describe their projects, workspaces, and custom workflows in an atlantis.yaml file, including pinned Terraform versions, execution order groups, and parallel planning or applying across projects. Because Atlantis runs inside your infrastructure, cloud credentials never leave your network, and every plan, approval, and apply is preserved on the pull request as an audit trail. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

pRESTd points at your PostgreSQL or MySQL database and instantly serves every table as a REST API, so the CRUD backend you were about to spend a week writing already exists. Every table answers at its own address with filtering, ordering, pagination, and column selection in the query string, and batch endpoints group several operations into one call. When a table endpoint is not enough, drop a SQL file into the queries folder and it becomes a named route with bound parameters, or store the scripts in the database and manage them through the admin API. Turn on the auth module and the server issues JWTs from your own users table, checks them on every route, and enforces table-level permissions so public tables stay open while payroll stays shut. The same database also appears as a read-only MCP endpoint, which lets Claude, Cursor, and other AI clients discover your tables and query them with your permissions instead of a copied export. One process can front several databases at once, Postgres and MySQL side by side, each under its own alias for tenants or reporting replicas. An embedded Studio in the same binary browses the catalog and rows, builds GET requests, and invokes MCP tools, so you can inspect everything from the browser before writing a line of client code.

Report cards, attendance rosters, class schedules, discipline logs, and fee statements all live in one browser-based system with RosarioSIS, an open-source student information system for K-12 schools and similar institutions. Administrators define marking periods in up to three tiers, set grade levels and daily periods, and search students by gender, grade level, schedule, absences, GPA, or class rank. The scheduler places whole classes or a single student, and runs in test mode each time a student's requests are saved, so conflicts can be resolved with the student still in front of you. Teachers keep a weighted gradebook with grade ranges, progress reports, report cards, and transcripts, take attendance electronically, and use the eligibility feature to flag who may join athletic or academic activities. Discipline logs, student billing with fees, payments, balances, and statements, food service, and accounting complete the core modules. Parents and students get their own portal, new families can register online, listings export to Excel, CSV, or XML, and charts and PDF documents support decisions and paperwork. The interface adapts to tablets and phones and is translated into a dozen languages. Add-on modules bring email, library, hostel, Jitsi Meet video rooms, and Moodle integration. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.

Flowsint turns scattered OSINT leads, like a domain, a username, an email, or a crypto wallet, into one interactive graph that you expand with a right click. Drop an entity on the canvas, run an enricher, and the results appear as new nodes with their relationships already drawn in. Over 30 built-in enrichers cover subdomain discovery, WHOIS and historical records, DNS and ASN lookups, IP geolocation, username searches with Maigret and Sherlock, breach checks for emails and phone numbers, Gravatar profiles, website crawling for contacts and tracking codes, and Ethereum wallet transactions and NFT transfers. Chain enrichers into flows so each output feeds the next step, then replay the same flow on any entity of that type. Missing a source? Write an enricher template in YAML, or describe the API in plain language and let the built-in AI draft it, with API keys kept in an encrypted vault instead of config files. Custom entity types, aliases, tags, JSON import and export, and basic role-based access control make it workable for small teams, and an n8n connector pipes findings into alerts and reports. Double-click the canvas to add items fast, or alt-drag between nodes to link them. Every graph stays on your own server, and no default accounts exist. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

A secure drop box for tips and misconduct reports, GlobaLeaks lets organizations, newsrooms, and public institutions receive anonymous submissions and reply to the people behind them. Whistleblowers answer a questionnaire, attach files, and leave with a unique 16-digit receipt that reopens their report later for replies, comments, and the choice of whether and when to reveal their identity. Administrators build the intake form with a questionnaire builder, route reports through channels by topic or department, and host several branded whistleblowing sites from one installation in more than 90 languages. Recipients triage in a searchable inbox with labels, reminders, and customizable case statuses. Analysts, custodians, and administrators get separate roles, and the custodian role can gate access to a reporter's identity. Reports and messages are encrypted, an automatic Tor onion service gives whistleblowers an anonymous way in, two-factor authentication protects staff logins, and PGP secures email notifications. Audit logs track staff actions, and retention rules expire old reports to support GDPR duties and EU Directive 2019/1937 workflows. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
