Open-source alternative to OpenAI's Canvas — a collaborative writing and coding environment where AI agents help you draft, edit, and refine documents through an agentic architecture built on LangGraph. The dual-mode editor combines a BlockNote rich text editor for live-rendered markdown with a CodeMirror-based code editor supporting syntax highlighting across multiple programming languages, letting you switch between prose and code artifacts within the same session. The built-in reflection agent automatically generates style rules and user insights from your chat history, storing them in a shared LangGraph memory store that persists across sessions for increasingly personalized assistance. Pre-built quick actions provide one-click access to common writing transformations including summarize, expand, simplify, and translate, while coding actions offer explain, refactor, add comments, and convert between languages. The monorepo architecture separates the Next.js 14 frontend from the LangGraph agent backend, connecting via HTTP and WebSocket protocols through the @langchain/langgraph-sdk client. Seven LLM providers are supported out of the box — OpenAI, Anthropic Claude, Google Gemini, Fireworks AI, Groq, Azure OpenAI, and local Ollama models — with Supabase handling authentication and data persistence. Deploy via Docker or build from source. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

With over 78,000 GitHub stars, 270 contributors, and seven years of continuous development tracking upstream VS Code releases within days, code-server has become the definitive way to run a full Visual Studio Code IDE on any remote machine and access it from any browser on any device. The project applies a curated set of patches to Microsoft's VS Code codebase that add password authentication, sub-path hosting behind reverse proxies, self-contained web views that never call out to Microsoft servers, a built-in proxy for accessing ports on the remote machine directly through the VS Code ports panel, and on-disk settings persistence instead of browser storage. The extension ecosystem works with the Open VSX marketplace by default, giving access to thousands of extensions for Python, JavaScript, Go, Rust, Java, and every other language, along with themes, linters, formatters, and debuggers. The integrated terminal provides direct shell access to the server, Git integration handles version control without leaving the editor, and the debugger supports breakpoints, variable inspection, and step-through execution for Node.js, Python, Go, and other runtimes. DevContainer support enables reproducible development environments defined in JSON configuration files. Installation options include a one-line install script, manual package installation, Docker via the official codercom/code-server image, and DevContainer features. Minimum requirements are a Linux machine with 1GB RAM, 2 vCPUs, and WebSocket support. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

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. 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.

An open-source alternative to Notion and Google Docs developed jointly by France's DINUM and Germany's ZenDiS that prioritizes data sovereignty, real-time collaboration, and structured knowledge management. The Yjs-powered CRDT engine provides live cursors, presence indicators, and inline comments enabling teams to edit simultaneously without conflicts, while BlockNote.js renders a clean block-based editing experience with rich text formatting, Markdown shortcuts, and drag-and-drop content organization. Hierarchical sub-documents create wiki-style knowledge bases where documentation nests naturally into navigable structures, and a dedicated slide mode transforms any document into a presentation without separate tooling. The document API separates content from metadata with distinct endpoints for formatted content, raw content streams, and document properties. Optional AI integration connects to configurable language models for writing assistance, summarization, and content generation directly within the editor. Access control supports granular permissions per document with team sharing, public links, and invitation flows. DOCX import brings existing documents into the platform while maintaining formatting fidelity. The Django backend serves a REST API with PostgreSQL storage, Redis caching, and S3-compatible media handling. Deploy via Docker Compose, Kubernetes with the official Helm chart, Nix, or YunoHost on your own infrastructure.

End-to-end encrypted by design, CryptPad is a real-time office suite where teams write documents, plan on kanban boards, collect answers with forms, and draw diagrams without the hosting server ever seeing their content. Rich text pages come with comments, replies, @mentions, and a document outline, while the Markdown editor adds a live preview, Mermaid diagrams, mind maps, and math. Kanban columns hold colored, tagged cards with Markdown bodies, and the diagram editor exports PNG, JPG, SVG, or PDF. Optional ONLYOFFICE editors add spreadsheets, word-processing documents, and presentations that several people can edit together. The form builder offers text, choice, grid, date, ranking, and poll questions, conditional sections, and separate author, auditor, and participant roles. Documents can be shared with contacts or teams, by link, or as embed code, with view, edit, present, or view-once access. Passwords, expiry dates, owner lists, and access lists limit who gets in, and every edit lands in a history you can step through, restore, or pin as a named snapshot. CryptDrive keeps files in folders, tags, templates, and a trash bin, while teams get their own drive, chat, and member roles. 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.

Multiple authors can edit the same LaTeX document simultaneously in the browser with live cursor tracking, conflict-free merging, and instant PDF compilation on every save.

One browser tab can hold every database you manage, from MySQL and PostgreSQL to MongoDB and Redis, so there is no separate client to install for each engine. Connections are unlimited, and each can use its own SSH tunnel or SSL certificates. Tables open in an Excel-like grid where you edit cells inline, filter rows with expressions, and sort by any column. The SQL editor offers schema-aware code completion, a formatter, a join helper that builds clauses from foreign keys, query parameters, and a history of past runs, while result sets appear in separate tabs that you can filter, sort, and export. ER diagrams chart tables and their relations. The table editor creates columns, keys, and indexes and previews the SQL before anything is applied. Import and export move data between databases and files as SQL, CSV, JSON, XML, NDJSON, Excel, DBF, or YAML. Administrators can preconfigure connections through environment variables, mark them read-only, and protect the interface with logins that carry per-user permissions. Light and dark themes, customizable keyboard shortcuts, and translations into many languages keep daily work comfortable.

Design a website on a canvas, manage its content in spreadsheet-style tables, and publish plain HTML, all from one self-hosted Instatic server. Designers see several breakpoint frames side by side, or switch to live mode and edit one full-size page in place. A built-in design system expands one brand color into a full shade scale, generates fluid type and spacing scales, and writes the utility classes into a single small stylesheet. Reusable Visual Components take typed parameters and named slots, templates set site-wide or per-post-type layouts, and loops repeat a design over posts or media. Editors work in custom post types and data tables, and posts move through draft, scheduled, and published states. Forms on the site save their submissions to tables of your own. An AI agent can do the building, placing real, editable nodes on the canvas using Claude, OpenAI, OpenRouter, or Ollama with your own key, and an MCP connector lets Claude, ChatGPT, and other remote agents work on the site too. Super Import converts a whole static site into pages, styles, tokens, and media. Teams get roles built from 38 capabilities, TOTP two-factor sign-in, and an append-only audit log, plus site branches with private copies, shareable preview links, and merge review. Everything published is baked to plain HTML and CSS on disk. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Wiki-Go turns a folder of Markdown files into a searchable team wiki with page history, comments, and access rules, and never asks you to run a database. Pages live in a nested tree with a sidebar and breadcrumbs, and an editor with a preview toggle handles emoji shortcodes, highlighted code, LaTeX math, Mermaid diagrams, collapsible sections, GitHub-style alerts, and embedded YouTube, Vimeo, or MP4 video. Full-text search supports exact phrases in quotes and term inclusion or exclusion, and highlights each match. Each save keeps a revision, up to a configurable limit, and any stored version can be restored later. Attachments such as PDFs, spreadsheets, images, and archives sit beside the page they belong to. Drop a Kanban board into any document for drag-and-drop task tracking with nested tasks, or build a categorized link library that fills in page metadata automatically. Signed-in users comment in Markdown, and admins can remove comments. Admin, editor, and viewer roles, user groups, path-based public or private rules, and an optional private-wiki mode decide who sees what. Branding comes from a custom logo, banner, and favicon, shortcodes such as stats insert live site statistics, and readers can switch between dark and light themes or print any page. A REST API opens content to scripts, and a community tool imports Notion exports.

Browse, upload, edit, preview, and archive the files on your server from any web browser, with no FTP client, no shell session, and no database to set up. Tiny File Manager lists every folder in a sortable table showing size, modified date, permissions, and owner, with a search box that filters as you type. Drag files into the upload zone, send several at once, or paste a URL for the server to fetch. Rename items, select several to copy, move, delete, or pack into a zip or tar archive, and extract uploaded archives on the server. Click any text file to open the built-in editor, which offers syntax highlighting for 150+ languages and 35+ color themes, so quick fixes to configs and scripts happen where the files live. Images, audio, video, and text open in a preview without downloading, and every file has a copyable direct link. Give teammates or clients their own accounts, each locked to a root folder you choose, mark accounts read-only, and limit uploads to approved file extensions. Hide folders you never want listed, restrict access with IP allow and block lists, switch between light and dark themes, pick from 35+ interface languages, and use the responsive layout on a phone. Setup is one file copied to a web server, or one Docker container. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
