Unplanned equipment downtime and scattered paper work orders cost facility teams hundreds of maintenance hours every year, an operational bottleneck that Atlas CMMS resolves through a centralized, self-hosted computerized maintenance management platform. Maintenance supervisors can create, prioritize, and assign reactive or scheduled work orders to internal technicians and external contractors, attaching multi-step inspection checklists, labor timers, and completion photos. Automated preventive maintenance rules generate recurring tasks on daily, weekly, monthly, or meter-based intervals so critical machinery receives servicing before breakdowns happen. Asset managers can organize hierarchical equipment registers mapped to physical facility locations via Google Maps, tracking downtime history, repair costs, and reliability metrics per machine. Built-in spare parts inventory management monitors stock levels with low-quantity alerts and links directly to purchase order creation and multi-stage vendor approval workflows. Non-technical staff can submit maintenance requests through a simplified service portal, while field technicians update tickets, scan barcodes, and log parts usage from the companion Android and iOS mobile apps. Executive analytics dashboards export compliance rates, mean time to repair, and labor cost breakdowns across 18 supported interface languages.

SolidInvoice ships a complete billing platform as a single FrankenPHP binary — no separate PHP installation, no web server configuration, just one executable that delivers quote-to-invoice conversion, automated recurring billing, Stripe and PayPal payment processing, multi-currency precision arithmetic, and eight render-ready PDF templates out of the box. Maintained since 2012 across 63 releases with 30 contributors, the Symfony 7 and PHP 8.4 backend provides quote creation with one-click conversion to invoices, recurring billing with configurable frequency schedules, and online payment processing through Payum supporting Stripe, PayPal, and additional gateways. Multi-currency support uses real Money objects for precision arithmetic, while multi-tax support handles invoice-level and line-item tax rates with automatic calculation. Client management stores contacts, multiple addresses with map integration, credit balances, and complete quote and invoice history per client. The redesigned Tabler-based UI features a dashboard with hero statistics, ChartJS revenue trend visualization, attention-required alerts for overdue and draft invoices, quick actions, and a recent activity timeline. A RESTful API enables integrations with external systems. Multi-channel notifications deliver alerts via email, SMS, and webhooks. Google OAuth and two-factor authentication secure access. Grid export and full company data export support backup and migration. Deploy using Docker, Homebrew, the standalone FrankenPHP binary, or from source.

Xalgorix delivers AI-driven penetration testing that proves vulnerabilities exist rather than guessing, pairing an autonomous LLM agent with an independent exploit verifier that re-exploits every finding before it reaches your report. The 22-phase methodology mirrors how a skilled human pentester works through an engagement, covering reconnaissance, subdomain enumeration, port scanning, web crawling, parameter fuzzing, SQL injection testing, XSS detection, authentication bypass, API testing, and more. Select all phases or pick specific ones per target. The platform ships with 85+ offensive security tools preinstalled (nmap, nuclei, httpx, subfinder, katana, ffuf, gobuster, sqlmap, masscan, dalfox, feroxbuster) plus 14 built-in agent tools for browser automation, terminal execution, and note-taking. Connect your own LLM provider (OpenAI, Anthropic, DeepSeek, Gemini, Groq, Ollama, or MiniMax) so no scan data or target information leaves your infrastructure. The web dashboard on port 9137 provides live WebSocket telemetry showing tool calls, agent reasoning, and findings as scans progress. A findings index with CVSS scoring and severity filters organizes results, and branded PDF reports include your company name and logo. Wildcard and multi-target scans handle red team attack-surface mapping, while source-code scanning audits repositories directly without requiring a deployed target. A REST API enables scripted scans and SIEM pipeline integration, and webhooks push notifications to Discord or Telegram. 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.

On the factory floor, the data already exists; it is just locked inside machines, PLCs, and protocols nobody on the analytics team speaks. StreamPipes unlocks it with guided adapters for OPC UA (including a web-based node browser), MQTT, Kafka, Pulsar, REST services, and industrial controllers, turning each source into a live stream in minutes. Domain experts then drag those streams into the pipeline editor, chain processors and sinks on a canvas, and watch connection validation check schema compatibility as they build, with live preview showing real values before anything is saved. Pipelines filter, enrich, aggregate, and route machine data, raise alerts, and write results to the built-in time-series data lake, where the data explorer charts history and spots trends. Finished pipelines run under an overview that starts, stops, and bulk-manages them, while detail views expose logs, metrics, status, and the pipeline as code. Live dashboards carry the same data to shop-floor screens and operations centers, organized around assets so a line, a cell, or a single machine becomes the navigation unit. Developers extend everything with custom adapters, processors, and sinks built on the Java SDK and deployed as microservices, or drive the platform from Python, Go, and Java clients.

Insights LM gives you a NotebookLM-style research assistant that runs on your own infrastructure and answers strictly from the documents you feed it. Build a notebook for a project, drop in PDFs, pasted text, website links, and audio files, then ask questions in plain language and get answers grounded in those sources rather than the open internet. Every answer carries citations you can click to jump straight to the passage it came from, so verifying a claim takes seconds instead of a fresh search. Findings worth keeping become notes saved alongside the notebook, building a private knowledge base that grows with your research. When reading is too slow, generate an audio overview and listen to two hosts discuss your material like a podcast episode, perfect for absorbing a long report on a walk. Teams use it to interrogate internal documentation, onboard new hires against company knowledge, and brief themselves before meetings without uploading confidential files to a third-party service. Because the whole stack is yours, you choose which AI models do the reading, including local models for fully private work. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Transforming fragmented research notes, daily technical logs, and project documentation into an interconnected knowledge base is what NoteDiscovery delivers for privacy-conscious teams and researchers. Writers compose rich documents using a dual-pane editor that renders MathJax equations, interactive task lists, and dynamic Mermaid sequence diagrams side by side with raw text. The interactive knowledge graph maps semantic relationships across notebooks, allowing researchers to explore backlinks, uncover hidden topical connections, and navigate complex idea webs visually. Team members sketch architecture diagrams and wireframes directly inside note canvases using the integrated drawing tool, saving revisions as embedded image layers without external editors. The platform organizes thoughts through flexible tag hierarchies, nested folder trees, and reusable document templates equipped with automatic date and variable substitutions. Autonomous coding assistants and language models query documentation, create structured meeting summaries, and update project indexes directly through the native Model Context Protocol server. Built-in export tools convert notebook collections into standalone HTML packages, printable documents, or portable Markdown archives for offline archiving.

GEOInflow is a self-hosted analytics platform that shows website owners which AI crawlers visit their pages, what those crawlers read, and how much traffic and revenue AI search actually sends back. Import a sitemap, CSV, or JSON inventory and the coverage report compares it against observed crawl logs, flagging important pages that no AI crawler has ever requested and directories where coverage keeps dropping. The built-in catalog recognizes 61 AI crawler identities, including crawlers from OpenAI, Anthropic, Perplexity, Google, Microsoft, ByteDance, Baidu, Kimi, and Tencent Hunyuan, and separates training, AI search, and user-triggered visits. Verification combines declared user agents with official IP ranges and DNS evidence, so a spoofed crawler name never counts as a confirmed visit. Browser tracking connects AI search referrals to landing pages, custom events, goals, funnels, and conversions, letting teams measure whether visibility in AI answers turns into signups and sales. Alongside the GEO reports, teams get pageviews, unique visitors, referrers, geography, devices, heatmaps, retention, and visitor paths, with CSV, JSON, and ZIP exports for any selected scope. Workspaces, team permissions, and public sharing links let agencies and publishers give each client or department its own dashboards without exposing raw data or other sites. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Fusio turns the data and services you already run into a managed API that partners, apps, and AI agents can actually use. The workflow starts small: add a database connection and a table becomes a REST endpoint, or proxy a remote service and route traffic between internal microservices. Each operation pairs an HTTP path with an action and a schema, so requests are validated and an OpenAPI specification plus client SDKs for major languages come out without extra effort. Custom behavior lives in reusable actions, and an AI assistant can draft actions and schemas from a plain-language prompt. Native Model Context Protocol support then offers those actions to autonomous agents as tools. Third-party developers get a self-service portal with documentation, testing tools, and their own keys. Every endpoint can be protected with scopes and rate limits. Asynchronous work runs through events, webhooks, cronjobs, and triggers. When the API becomes a product, plans, quotas, and transactions handle billing, and analytics follow usage, performance, and errors. A marketplace installs ready-made actions and apps, and the generator and test panels speed up development.

Backrest turns the command-line restic backup engine into a visual, browser-managed disaster recovery platform that schedules encrypted snapshots, orchestrates repository maintenance, and restores individual files from a unified web dashboard. Import existing restic repositories or initialize new encrypted backup stores across Amazon S3, Backblaze B2, Google Cloud Storage, Azure Blob Storage, SFTP servers, local directories, and any storage provider supported by rclone. Define granular backup plans with directory inclusion lists, glob exclusion rules, and flexible schedules driven by cron expressions, hourly intervals, or last-run-time clocks that prevent missed backups after server downtime. Automated retention policies handle snapshot forgetting, repository pruning, and cryptographic integrity checks in the background without manual intervention. When a file is accidentally deleted or corrupted, open the interactive snapshot tree browser to inspect historical directory structures and download or restore specific files directly to disk. Pre-backup and post-backup shell command hooks let administrators dump databases or pause containers before snapshots start, while configurable alerts dispatch status reports to Discord, Slack, Gotify, Healthchecks, and Shoutrrr endpoints whenever an operation succeeds or fails. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Upload files, get a share link, let it expire: PsiTransfer is a self-hosted WeTransfer with no accounts, no logins, and no third-party cloud with size caps and metadata harvesting. The engineering focus is large files over imperfect networks. Uploads use the tus.io resumable protocol, so a dropped connection on a multi-gigabyte video resumes exactly where it stopped once you're back online; downloads support HTTP range headers for the same resilience, and everything streams, so file size is bounded by your disk rather than memory. Files organize into upload buckets with retention you control: expire after a set time (up to weeks) or after a one-time download, with automatic cleanup when links lapse. Recipients need nothing installed - they open the link, preview files in modal views, and grab everything as a zip or tar.gz archive with one click. Buckets can be password-protected (AES-encrypted download lists), and security-through-obscurity is done properly: bucket URLs use hashed UUID tokens and stored filenames are replaced with UUIDs. An optional admin page (enabled by setting an admin password) lists bucket information and storage. The Vue.js frontend ships under 100 KB gzipped and is fully responsive. Honest caveat from the author: no end-to-end payload encryption yet. BSD-licensed, Docker-ready.

Why should your chat history live on someone else's servers? Chatpad AI - a React/TypeScript front end for the OpenAI API, built on the Mantine component library - is designed around that question. Enter your own OpenAI API key and start chatting with GPT models; every conversation, prompt, and setting is stored locally in your browser via DexieJS over IndexedDB, with no tracking, no cookies, and no backend database at all. That architecture is the point - the Docker image is just Nginx serving static files, making it one of the lightest AI deployments in the catalog, and pay-per-token API pricing typically undercuts a ChatGPT Plus subscription for moderate use. The interface earns its "premium quality" tagline with the details: a persona selector that switches communication styles per conversation, a saved-prompts library for messages you reuse constantly, organized chat history, and full data export/import so conversations move between browsers or into backups as files you control. A JSON config file customizes defaults - models, API endpoints, UI options - without rebuilding the image. AGPL-licensed, with desktop builds available upstream. For teams that want ChatGPT's utility with a self-hosted, zero-telemetry footprint, Chatpad is the minimal, sane answer.

Point Sirius Scan at a network range and it finds live hosts, fingerprints their services, and lists every matching CVE with its CVSS score in a live web dashboard. The Vulnerability Navigator groups findings by severity, filters on CVSS, and exports results for remediation tracking. Scans run on Nmap with NSE scripts kept in sync with upstream, alongside Naabu port scanning. Lightweight remote agents connect back over gRPC from other networks, so segments the central scanner cannot reach still get assessed, and the same agents can run YAML detection templates locally in CLI mode with no server connection at all. An operator console runs PowerShell commands against connected agents and keeps command history beside the scan results. Real-time progress, severity trend charts, host detail pages, and an environment overview show what changed between scans. A REST API on port 9001 with API key authentication feeds results into existing security workflows, while service health monitoring and centralized logging confirm the platform itself is behaving. An installer generates fresh secrets and an initial admin password, and production overlays tighten the deployment further.

Marketing campaigns and transactional mail from one open-source platform: Notifuse is a modern, self-hosted alternative to Mailchimp, Brevo, and Klaviyo without per-email or per-contact pricing. Built with Go and React on PostgreSQL, it separates concerns cleanly: a drag-and-drop visual builder composes responsive templates from MJML components with Liquid variables like {{ contact.first_name }} and per-template version history; campaigns add A/B testing across subject lines, content, and send times; and a REST transactional API serves application-triggered mail. Delivery routes through your choice of provider - Amazon SES, Mailgun, Postmark, SendGrid, SparkPost, Mailjet, or plain SMTP - with multi-provider failover. Contacts carry custom fields and a full activity timeline (messages, profile changes, webhook events), and real-time segmentation builds dynamic rules over properties, activity, and subscriptions. Event-driven automations create behavioral sequences, a notification center gives recipients self-service preference management, and an S3-compatible file manager handles images with CDN delivery. Multi-tenant workspaces with isolated databases and custom domains suit agencies. Open and click tracking report engagement in real time.

With nearly 5,000 GitHub stars earned in under two years, WhoDB has rapidly emerged as the lightweight alternative to heavyweight database clients like DBeaver and DataGrip by delivering a sub-50MB binary that starts in under a second and connects to 18+ database systems from a single interface. The Go backend serves the React and TypeScript frontend with table virtualization for efficient rendering of large result sets, lazy loading, and query result streaming that keeps the interface responsive even when browsing tables with millions of rows. The Community Edition connects to PostgreSQL, CockroachDB, YugabyteDB, MySQL, MariaDB, TiDB, SQLite, DuckDB, MongoDB, FerretDB, Redis, Valkey, Dragonfly, Elasticsearch, OpenSearch, ClickHouse, QuestDB, and Memcached through a unified credential selector that switches between databases with minimal configuration. Interactive schema diagrams render entity-relationship graphs showing table structures, foreign keys, and column types for visual database exploration. The Jupyter-style query scratchpad provides SQL autocomplete, syntax highlighting, and multi-statement execution with paginated results. AI integration optionally connects to Ollama, OpenAI, Anthropic, LM Studio, or any OpenAI-compatible provider for natural language database queries — ask questions in plain English and receive generated SQL. Data management includes inline row editing, CSV export, and filtered data views. Docker deployment runs a single container exposing port 8080.

SnappyMail is a fast, privacy-respecting webmail client that connects to any existing IMAP and SMTP server, booting in under a second with a JavaScript payload of just 138 KB under Brotli compression (down from RainLoop's 8 MB fork origin). No database is required: all configuration and user data persists as flat files in a single volume, making Docker deployment trivially simple with the roughly 30 MB image consuming approximately 50 MB of RAM. Built-in PGP encryption supports three backends: OpenPGP.js v5 with ECDSA and EDDSA key generation, GnuPG integration, and Mailvelope browser extension compatibility, eliminating the need for separate encryption plugins. The integrated Sieve script editor enables users to create mail filtering rules, vacation auto-responders, and forwarding conditions directly within the web interface when connected to ManageSieve-capable servers on port 4190. Multi-domain administration allows a single instance to serve users across multiple IMAP servers with per-domain authentication routing. The admin panel manages extensions, security settings, branding customization, and domain configuration. GDPR-friendly by design, it removes all social media integrations, Gravatar lookups, and external tracking present in RainLoop. Dark mode strips background and font colors from email messages. The modified Squire HTML editor replaces CKEditor for composing rich-text messages. Scores 99% on Lighthouse performance.

Mox offers a complete mail server stack in a single Go binary requiring no external dependencies. The quickstart command configures a working mail server with SMTP, IMAP4, webmail, and full DNS authentication in under ten minutes. SMTP handling includes a delivery server on port 25, a submission server for authenticated clients, and a queue with automatic retries and DKIM signing. IMAP4rev2 implementation provides full mailbox synchronization with CONDSTORE and QRESYNC for efficient offline clients, NOTIFY for multi-mailbox monitoring, MULTISEARCH across mailboxes, and TLS client certificate authentication via the EXTERNAL SASL mechanism. The built-in webmail provides browser-based reading and composing with message threading, attachments, and HTML rendering without requiring a separate web client. Email authentication implements SPF validation, DKIM signing and verification with automatic key rotation, DMARC policy enforcement with aggregate and failure reporting, DANE with DNSSEC-protected TLSA records, and MTA-STS for certificate verification. Junk filtering combines reputation-based sender scoring with Bayesian content analysis trained per account. The web administration interface manages domains, accounts, DNS records, TLS certificates, delivery queue, and real-time log viewing. Internationalized email addresses with EAI and IDNA support handle non-ASCII domains and mailboxes. Account autoconfiguration publishes settings for Thunderbird autoconfig and Outlook autodiscover. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Enterprise documentation discipline without enterprise infrastructure: Documize Community is the Confluence alternative built on exactly that trade. The entire platform - Go backend, Ember.js frontend - compiles to a single executable binary for Linux, Windows, and macOS with zero runtime dependencies: no Elasticsearch, no Redis, no JVM. Point it at PostgreSQL, MySQL, MariaDB, Percona, or Microsoft SQL Server (rare in open source, decisive in Microsoft shops), and schema migrations run on launch with native full-text search on whichever engine you chose. Content organization rejects nested-folder sprawl for Spaces, categories, and labels, and the section-based composable editor mixes rich text, Markdown, code blocks, PDFs, diagrams, and embedded Jira or Trello content in one document, with reusable blocks and templates so teams start from standards rather than blank pages. It deliberately unifies internal team docs and customer-facing documentation in one system with granular space-, document-, and action-level permissions deciding who sees what. Where wikis stop, Documize continues: content approval workflows (draft, review, approve, publish), version management, lifecycle control, feedback capture, PDF export, analytics showing what gets read and ignored, activity streams, and audit logs. Keycloak, LDAP, and SSO integrate for enterprise auth. AGPL-licensed.

Backed by 1,080+ GitHub stars and maintained by Percona with the latest release v3.8.1 in June 2026, Percona Monitoring and Management delivers the open-source database observability platform that provides a single pane of glass across MySQL, PostgreSQL, MongoDB, Valkey, and Redis databases deployed on-premises, cloud, or hybrid environments. The Go-powered PMM Server collects metrics from lightweight PMM Client agents with minimal performance impact, storing time-series data in ClickHouse for fast querying across configurable retention periods. Query Analytics ranks every query by load across all database engines from one unified dashboard, drilling from fleet-level performance down to individual problematic queries with explain plans, per-query metrics, and anomaly detection. Real-time Query Analytics streams live MongoDB operations updated every 1-5 seconds for immediate troubleshooting of lock contention and long-running queries.
