Marimo is a reactive Python notebook that treats cells like spreadsheet formulas: change one cell or interact with a UI widget and every dependent cell automatically re-executes, eliminating the hidden state bugs that make traditional notebooks unreliable. Backed by over 22,000 GitHub stars, notebooks are stored as pure Python files with PEP 723 inline metadata, making them Git-diffable, importable as modules, executable as CLI scripts with parameterized arguments, and testable with PyTest. Built-in SQL cells query Polars, Pandas, PyArrow, DuckDB, SQLite, PostgreSQL, and MySQL databases, with results automatically flowing into the reactive dependency graph. The AI-native editor provides GitHub Copilot autocomplete, context-aware assistants that access live runtime variables, inline code edits powered by configurable models from OpenAI, Anthropic, or local Ollama instances, and a pair mode that lets external AI agents connect over WebSocket. Notebooks become read-only interactive web applications with marimo run, collaborative authoring environments with marimo edit, or embedded flows inside existing FastAPI applications through ASGI middleware. Gallery mode serves multiple notebooks from a single instance with an auto-generated index page. The Docker image ships with SQL support, token-based authentication, health check endpoints at /health and /api/status, and configurable WebSocket or SSE kernel transport for proxy compatibility.

OpenCode Manager is a mobile-first command center for AI coding agents. Install the PWA on your phone or tablet and you get real-time streaming chat, multi-repository Git operations, and scheduled automation right in your pocket. Git integration handles SSH-authenticated repo cloning, worktree management, unified diffs, and branch operations across all your projects in one dashboard. Chat with coding agents through Server-Sent Events streaming that supports slash commands, @-mentions for files, Plan and Build modes, and Mermaid diagram rendering for architecture discussions. Schedule reusable prompts to run against any repository on intervals or cron expressions, with each run tracking history and linking to sessions so you can pick up exactly where automation left off. MCP server configuration adds local and remote HTTP servers with OAuth support, plugging into the broader Model Context Protocol ecosystem. A dedicated assistant workspace provides an isolated AI environment with auto-provisioned skills for managing schedules, notifications, and settings. Multiple AI providers are supported including Anthropic, GitHub Copilot, and OpenAI-compatible services, each configurable with custom system prompts and granular tool permissions. Push notifications alert you to session events, agent questions, errors, and task completions across all managed repositories.

Your calendars and contacts do not need a cloud account, and Baikal is the small PHP server that keeps them on hardware you control while still syncing to every phone and laptop you own. The web admin panel is where you add users, create their calendars and address books, and reset passwords, no database editing or config files required. Each person signs in with their own username and password, so an iPhone, an Android phone running DAVx5, and a Thunderbird desktop can all stay in sync without sharing one master credential. Standard well-known redirects mean most clients configure themselves when you type the server address, and the combined dav.php endpoint serves calendars and contacts from a single URL. Events carry the full CalDAV feature set your clients expect (recurring appointments, reminders, attendees, and free-busy lookups), while CardDAV address books keep names, phone numbers, and photos in one place. Because storage is a plain database file or table set, backups are a copy you can make in seconds, and moving to a bigger host is a file transfer rather than a migration project. The same server happily runs for one person tracking a family calendar or for a small office sharing team schedules and a company address book.

BrightBean Chat is a self-hosted chat automation platform that builds visual flows once and runs them across Instagram, WhatsApp, Messenger, Telegram, SMS, and email, so your audience automations live on your server instead of a per-contact subscription. You drag conditions, delays, randomizers, data collection, and message nodes onto a canvas, test the draft while the live version keeps running, then set it live with every save versioned. Flows start from keywords, comment-to-DM triggers, story mentions and replies, follows, ref URLs, QR codes, or calls to the public API. Every channel lands in one shared inbox where teammates assign conversations, label them, schedule replies, and take over from the bot, which pauses the automation for that contact. Contacts carry custom fields, tags, and segments that stay unified across channels, and imports and exports keep the list portable. Broadcasts and multi-step drip sequences check opt-outs and each platform's 24-hour messaging window before sending, pace themselves per channel, and show exactly who will receive a message and who is skipped. Per-node counters track sent, delivered, failed, and clicked, while a bearer-authenticated REST API and signed webhooks hand leads to Make, Zapier, n8n, or your own systems.

With over 11,200 GitHub stars and adoption by France's sovereign digital workspace LaSuite serving 20,000+ government users, Grist is the relational spreadsheet that ends the false choice between fragile Excel files and expensive custom database development — storing all data in portable SQLite files while providing true relational structure where VLOOKUPs become actual linked records that update instantly across entire documents. Python-powered formulas replace complex Excel syntax with clear, readable logic using the full Python standard library, while familiar Excel functions remain available for users who prefer them. Granular access rules control permissions at row, column, table, and cell levels — not just entire sheets — enabling multi-department documents where each team sees only their authorized data. The flexible layout system combines spreadsheets, card views, charts, calendars, and custom widgets on configurable dashboard pages that transform raw data into operational interfaces. Real-time collaboration lets multiple users edit simultaneously with automatic snapshot history capturing every change for full audit trails and point-in-time recovery. AI formula assistance connects to OpenAI, Llama, or any OpenAI-compatible endpoint via OpenRouter to generate formulas from natural language descriptions. The REST API and webhooks enable integration with n8n, Zapier, and custom automation, while incremental imports keep external data sources synchronized. Deployable via Docker with OIDC, SAML, and SCIM authentication support. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Kokoro-FastAPI turns text into natural-sounding speech across eight languages by serving the 82-million-parameter Kokoro-82M model through an OpenAI-compatible REST API, so any existing OpenAI SDK client can generate audio by just changing the base URL. With over 5,300 GitHub stars since December 2024, the fully Dockerized FastAPI server covers American English, British English, Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese, and Mandarin Chinese with language-specific phoneme processing. Inline voice mixing blends multiple profiles using weighted ratios like af_bella(2)+af_heart(1), automatically normalizing weights and caching combined voicepacks as PyTorch tensor files for reuse. Audio streams in real time over HTTP with configurable chunk sizes, or generates complete files in MP3, WAV, OPUS, FLAC, AAC, or PCM formats with speed control from 0.25x to 4.0x. Per-word timestamped captions with speaker-tagged voice labels enable subtitle generation for podcasts, audiobooks, and accessibility workflows. Pre-built Docker images support NVIDIA GPU acceleration via CUDA, experimental AMD GPU inference via ROCm, and CPU-only deployment on linux/amd64 and linux/arm64 architectures, with Apple Silicon MPS support available through direct UV execution. The integrated web interface at port 8880 provides browser-based speech generation, while the Swagger UI at /docs exposes the full API reference. Debug endpoints report system statistics for monitoring inference load. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Processing over one billion tasks per month on Hatchet Cloud and holding 7,600+ GitHub stars, Hatchet is the open-source orchestration engine that replaces fragile legacy queues with durable, fault-tolerant task execution built entirely on PostgreSQL — no Redis, RabbitMQ, or Kafka required. Born from the creators' experience scaling Uber's Cadence-inspired patterns, the v1 engine achieves 10,000 tasks per second sustained throughput with 20ms average queue latency through dynamic buffer flushing and batch insert optimization. Define tasks, durable workflows, and DAG pipelines as code using native SDKs for Python, TypeScript, Go, and Ruby — every function gets automatic retries with configurable backoff, concurrency control with group round robin or cancellation policies, priority queuing, and dynamic rate limiting for third-party API protection. Durable execution persists the complete history of every task and state transition, enabling replay from failure, debugging via full event timelines, and complex pause/resume conditions using durable sleep and event waits. The real-time web dashboard provides workflow run visualization with DAG timeline rendering, worker health monitoring with slot utilization, queue depth metrics, task throughput charts, and error rate tracking — all filterable by status, workflow, or time window. OpenTelemetry integration and Prometheus metrics export enable advanced observability. Multi-tenant by default with users, roles, and namespace isolation. Self-host via Docker Compose with PostgreSQL and optional RabbitMQ, or use the single-container Hatchet Lite image for development.

Execute comprehensive multi-angle investigations across scientific journals and web repositories using Local Deep Research, an autonomous intelligence engine designed for researchers, analysts, and knowledge workers. Users can submit complex analytical questions through a self-hosted web console to initiate agentic research cycles powered by LangGraph workflows. The application dynamically queries search providers including SearXNG, arXiv, PubMed, Wikipedia, and Google, iteratively evaluating discovered content to formulate targeted follow-up queries. Discovered academic papers and web sources can be indexed into an encrypted personal library to combine internal documentation with external search intelligence. Reports are synthesized with structured outlines, section headings, and verifiable academic citations that link directly to source references. Individual research sessions, system logs, and user credentials remain isolated in per-user SQLCipher databases protected by AES-256 encryption. Automated subscriptions deliver scheduled news digests and topic monitoring summaries directly to connected notification channels.

Every account you run deserves its own browser identity, and FoxProfile keeps those identities permanently separate instead of letting them bleed into one another. Create a profile once and it remembers its device: screen, GPU, CPU cores, fonts, and canvas noise are generated on first launch and reused on every later one, so the fingerprint a site saw yesterday is the fingerprint it sees tomorrow. Sessions stick too: history, cookies, and logins live in the profile directory, and the tabs you left open reopen where you left them. Each profile carries its own proxy (HTTP, HTTPS, SOCKS4, or SOCKS5, with a built-in checker) while timezone and locale follow the exit IP automatically or stay pinned to your choice, and the Check IP button compares the exit address across three services and flags mismatches or datacenter addresses. Cookies move in and out as standard editor JSON or Netscape files, whole profiles travel as ZIP archives, and bulk actions launch, stop, or delete fleets at once. On a server, the web panel runs profiles headlessly so you can manage them and view their screens from anywhere, the REST API scripts everything, and the MCP server lets AI agents drive the browsers directly.

OpenGTM turns a market, a list, or a workbook into enriched, researched, ready-to-contact prospects on servers you control. Give it a market and it sources companies and people; hand it a CSV or a Clay table and it maps the columns into a shared record library. Enrichment columns run as waterfalls that try providers in cost order until a field is filled, and before anything spends a cent you see best and worst case estimates, with a workbook budget ceiling that halts paid calls on its own. Research columns send an agent to answer the hard question for each row, and the answer keeps citations to the pages it actually fetched, so a human can audit the claim before outreach. Live audiences segment your records and watch for hiring and buying signals, refreshing on schedules and firing automations when a prospect heats up. Finished rows flow out to HubSpot, Salesforce, Slack, Sheets, Airtable, Instantly, Smartlead, webhooks, or a warehouse, while every cell keeps a trace of provider attempts, latency, and cost. Your own agents get the same workspace through a REST API, webhooks, and an MCP server with scoped read and write tokens, and a seeded zero-key demo means the team can explore the whole loop before adding a single provider key under Settings.

MediaMTX sits between cameras and viewers as a self-hosted live media server, taking in video and audio streams over one protocol and handing them back out over another, so one IP camera feed can end up playing in a browser, a phone app, and a recording archive simultaneously. Publish with FFmpeg, GStreamer, OBS Studio, a browser, or a Raspberry Pi camera over RTSP, RTMP, SRT, WebRTC, Media-over-QUIC, HLS, MPEG-TS, or RTP, and read it back on any other protocol without a transcoding pipeline. Run dozens of camera feeds side by side, each on its own path, and keep every path available even while its publisher is offline. Record everything to disk in fMP4 or MPEG-TS as it streams, then play recordings back later through the same server instead of shipping files around. Authenticate publishers and viewers with built-in users, an external HTTP check, or JWT, and use the control API plus Prometheus metrics to wire the server into the rest of your monitoring stack. Forward streams to other servers, proxy cameras behind NAT, and fire hook commands whenever a client connects, publishes, or disconnects, so a doorbell camera can trigger a snapshot or an alert as it starts streaming. Reload the configuration while clients stay connected, and tune everything from the same mediamtx.yml file or environment variables, with no database or runtime dependencies to babysit.

A streaming-style music player for your own Navidrome, Jellyfin, or OpenSubsonic server, on the desktop or in a browser. Home leads with a featured carousel, genre shortcuts, most played, and newly added releases. Browse by album, artist, genre, folder, or radio station. Queue, lyrics, and visualizer panels can each sit in the player sidebar. Japanese lyrics can show furigana and romaji. Star ratings, favorite hearts, and scrobbling to your server come built in. Shape the sound with a parametric equalizer, a compressor, ReplayGain, and optional transcoding. Auto DJ tops up a dwindling queue with songs or whole albums. Navidrome smart playlists get a visual rule editor with match-all or match-any groups. Choose from 32 built-in themes and 39 interface languages. The catch: Feishin is only the player, so the music server stays separate. In a browser it plays through the web player backend, while the desktop app adds MPV and built-in lyrics fetching. Docker environment variables can preset and lock the server, so guests only type a username and password.

A plain text journal is all Paisa needs to put your net worth, cash flow, expenses, and investment returns on one set of dashboards. Write entries in the built-in editor. It brings syntax highlighting, auto completion, error checking, and auto formatting to double-entry journals. Bank and credit card statements in CSV, Excel, or PDF import through reusable templates that categorize every transaction. Price providers track mutual funds, NPS holdings, and stocks. Manual prices revalue a house, a car, or a plot of land. Budgets set a limit for each category and track spending against it. Allocation targets show how far a debt and equity split has drifted. Goals compute a completion date from monthly savings. The retirement planner works from a safe withdrawal rate and yearly expenses. A calendar marks recurring bills as cleared, late, past due, or upcoming, and Liabilities pages cover credit cards, loan repayment, and interest. Live Sheets calculate taxes and EMIs from ledger data. Journals and settings stay in plain text files that can be version controlled or shared, and ledger, hledger, and beancount are all supported.

Backed by 4,800+ GitHub stars and trusted by teams replacing LaunchDarkly and Split with a self-hosted solution, Flipt v2 delivers the first truly Git-native feature management platform that treats feature flags as code stored in your own repositories. The architecture eliminates all database dependencies by building immutable in-memory snapshots from YAML flag definitions on every Git commit, delivering sub-millisecond evaluation latency with zero external runtime dependencies beyond the single Go binary. Multi-environment support maps directly to Git abstractions — separate repositories per environment, different directories within the same repository, or different branches — enabling teams to use their existing branching strategy, pull request workflows, and code review processes for flag changes. The evaluation engine supports boolean flags, multivariate string and numeric variants, segment-based targeting with constraint rules, percentage rollouts, and namespace isolation. Native SCM integration with GitHub, GitLab, BitBucket, Azure DevOps, and Gitea creates merge proposals directly from the UI with GPG-signed commits. Flipt implements the OpenFeature Remote Evaluation Protocol with official providers for Go, Node.js, Python, Java, C#, Ruby, and Web SDKs, enabling vendor-agnostic flag evaluation across all services. The gRPC API with REST HTTP gateway exposes flag management, evaluation, and analytics endpoints. Offline mode continues serving flags when the source repository is temporarily unavailable.

Undb turns a browser tab into a full-featured database with spreadsheet-style editing, auto-generated REST APIs, and five configurable views for every table. The platform organizes data through Spaces, Bases, and Tables, offering grid view for traditional editing, Kanban boards for workflow tracking, calendar for date-based planning, gallery for image-rich records, and pivot tables for analytical summaries, each with independent filtering, sorting, color coding, and field selection. An ANTLR4-powered formula engine provides Airtable-style calculated fields with proper syntax validation, variadic argument handling, and type-checked function signatures that go beyond simple string interpolation. Every table automatically generates a fully documented OpenAPI REST endpoint with Swagger UI, letting developers integrate Undb data into external applications through standard HTTP methods without additional configuration. The Drizzle ORM abstraction layer supports four database backends (SQLite, PostgreSQL, MySQL, and Turso edge-distributed SQLite) with separate migration configurations for each adapter. Authentication uses Lucia with OAuth2 via Arctic for GitHub login and Oslo for TOTP two-factor authentication. The SvelteKit 5 frontend renders through Houdini's compile-time GraphQL client and TanStack Svelte Query, while the Elysia.js backend compiles into a single executable via Bun's --compile flag, embedding all assets into one portable binary. File attachments store in any S3-compatible backend including MinIO. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

The Bitwarden server, reimplemented in Rust: Vaultwarden (formerly bitwarden_rs) is the unofficial lightweight edition. It speaks the same wire protocol as the official server, so every official Bitwarden client - browser extensions, iOS, Android, desktop, and the bw CLI - connects without modification, while the server itself runs as a single container against SQLite (or MySQL/MariaDB/PostgreSQL) instead of the official multi-container stack that wants gigabytes of RAM. Features Bitwarden gates behind paid tiers ship free: organizations with collections, groups, member roles, and policies; TOTP code storage; file attachments; Bitwarden Send; Emergency Access; event logs; and admin password reset. Two-factor options cover authenticator apps, email, FIDO2 WebAuthn, YubiKey, and Duo, and OIDC-based SSO landed natively in v1.35.0. Zero-knowledge encryption is unchanged - vault data is encrypted client-side and the master password never reaches the server. Attachments and Sends store on local disk or S3-compatible backends, an admin panel manages users and server settings, and backup is copying one data directory. Suited to individuals and teams up to roughly 50 users.

ODS turns a GPU machine or server you already own into a complete private AI stack with a single install command, replacing a shelf of separate tools with one system that serves models, chat, agents, automation, and search from your own hardware. The installer reads your GPU, VRAM, memory, and disk, then downloads a GGUF model matched to that hardware tier, and a compact bootstrap model starts answering within minutes while the full model finishes downloading. From the web dashboard you watch every service's health, ports, and resource use, restart what misbehaves, and check storage and updates without touching a terminal. You chat with local models in Open WebUI, hand background work to the Hermes and Portal agents, and build automations in n8n that connect the stack to more than 400 other apps. Documents you add become searchable knowledge through Qdrant vector storage, so answers cite your files instead of the model's memory. SearXNG and Perplexica answer web questions without trackers or accounts, Whisper transcribes speech, Kokoro reads text aloud, and ComfyUI generates images, all on the same box. Every bundled service is an extension you can enable, disable, or replace, and a Privacy Shield scrubs personal data before anything reaches an optional cloud model through the LiteLLM gateway.

Engineering teams and technical writers maintain operational runbooks, system documentation, and knowledge bases using LeafWiki, an open-source self-hosted wiki that stores page contents directly as human-readable Markdown files on the local filesystem. Authors can compose documentation through a dual-pane editor equipped with live HTML preview, keyboard navigation, autocomplete for internal links, and native rendering for Mermaid diagrams, KaTeX mathematical formulas, and collapsible callout containers. The navigational tree organizes complex documentation into explicit directory hierarchies and custom drag-and-drop page sequences tracked in lightweight configuration files rather than arbitrary alphabetical lists. An integrated SQLite engine indexes page content and custom taxonomy tags for fast full-text searches, automatic incoming backlink tracking, and automated broken link detection. System operators can deploy the single-binary application without external database servers or runtime dependencies, backing up the entire repository by copying the data directory. Administrators can provision granular user roles, configure reverse proxy header authentication for single sign-on gateways, and manage read-only API access keys for automated documentation scripts and continuous integration pipelines. Public viewers can browse technical notes without authentication or switch between dark and light high-contrast themes.
