# FreeAppStore > FreeAppStore is on a mission to rebuild everyday apps for the web. The web is cheaper to build on and run than native, especially with AI, so apps here are free: nothing to download, no ads, no trials, no subscriptions. > > It is a free, open-source app platform where developers publish PWA apps at `.freeappstore.online`. Apps are built with TypeScript, React, and Vite, deployed via GitHub Actions to Cloudflare R2. The platform provides an SDK with auth, per-user storage, real-time rooms, and UI components. Every app is free forever and MIT-licensed. Apps take no payments, and tracking SDKs can't be bundled into app code; analytics, if an app uses any, go through the platform loader. For the full AI agent guide, see [SKILLS.md](https://freeappstore.online/skills.md). ## About - [Our mission](https://freeappstore.online/about): Rebuilding everyday apps for the web, free for users and creators. - [How it's free](https://freeappstore.online/how-its-free): Web apps cost far less than native; platform costs are covered by ProAppStore, which earns from Pro app subscriptions. - [Web apps vs native apps](https://freeappstore.online/web-apps-vs-native): No download, one codebase, no ads or subscriptions needed. - [FAQ](https://freeappstore.online/faq): Common questions from users and creators. ## AI Agent Integration - [SKILLS.md](https://freeappstore.online/skills.md): Complete platform guide for AI agents. Tech stack, SDK reference (auth, KV, counters, collections, rooms, proxy), UI components, CLI commands, deploy flow, compliance rules. Point your AI agent here. - [MCP Server](https://mcp.freeappstore.online/mcp): Remote MCP server (Streamable HTTP). Drives the full build loop in two modes: (a) your AI writes the code — `create_app`, `update_files`, `read_file`, `list_files` (write a file, it auto-redeploys); (b) the platform's VibeCode agent writes+deploys from a prompt — `agent_build`, `agent_status`. Plus inspect/reference: `list_apps`, `app_info`, `deploy_status`, `app_logs`, `platform_guide`, `sdk_reference`. Connect with `npx mcp-remote https://mcp.freeappstore.online/mcp`. - [MCP Discovery](https://freeappstore.online/.well-known/mcp.json): Auto-discovery endpoint for MCP clients and registries. - [MCP Docs](https://docs.freeappstore.online/mcp/): Setup guide for Claude Code, Cursor, and other MCP clients. - [MCP Auth](https://docs.freeappstore.online/mcp/#authentication): OAuth 2.1 (automatic via mcp-remote) or Bearer session token. Write tools verify per-app ownership. - [MCP Security](https://docs.freeappstore.online/mcp/#security): Scoped tokens, session isolation, rate limiting, read-only mode, dry-run support. No generic shell/API proxy. - [MCP Capabilities](https://docs.freeappstore.online/mcp/#capabilities): What's read-only, what's write-protected, what's not supported via MCP. - [Agent Instructions](https://github.com/freeappstore-online/platform/blob/main/AGENTS.md): Repository instructions for platform contributors; main-only delivery and issue placement. ## SDK - [@freeappstore/sdk on npm](https://www.npmjs.com/package/@freeappstore/sdk): Platform SDK. `initApp()` gives you auth, KV storage, counters, collections, real-time rooms, API proxy, user API key vault, React hooks, and React UI components. - [SDK Docs](https://docs.freeappstore.online/): Full SDK documentation with examples for every feature. - [UI Component Library](https://docs.freeappstore.online/ui/): Shell (the standard app frame: wrap every app in `` with one nav item per screen; alias FasShell), PageHeader, NavBar, useToast, useDocumentTitle, useOnline, Avatar, SignInButton, ThemeToggle, ProfileMenu, ProfilePage, Spinner, Badge, Card, Tabs, Modal, ConfirmDialog, EmptyState, ProgressBar, SearchInput, ListRow, ErrorBoundary, KeyPrompt. - [API Key Vault](https://api.freeappstore.online/v1/keys): Platform-hosted key management page. Users store encrypted API keys (OpenAI, Anthropic, etc.) that apps access via the proxy. Apps never see plaintext keys. - [Free Libraries & APIs](https://freeappstore.online/skills.md#free-apis-no-key-required): 25 free tools that need no API key. Libraries: Leaflet (maps), Recharts (charts), Tiptap (rich text), date-fns, dnd-kit, Framer Motion, Lucide icons, Zustand. APIs: Open-Meteo (weather), Nominatim (geocoding), OSRM (routing), REST Countries, Wikipedia, and more. ## CLI - [@freeappstore/cli on npm](https://www.npmjs.com/package/@freeappstore/cli): CLI for scaffolding, compliance checks, and publishing. Commands: `fas init`, `fas check`, `fas publish`, `fas login`, `fas list`. ## For Developers - [Build with AI](https://freeappstore.online/build-with-ai): Step-by-step guide to building an app with Claude Code, Cursor, Codex, or any AI tool. - [Get Started](https://freeappstore.online/get-started): Manual setup guide without AI. - [Guidelines](https://freeappstore.online/guidelines): Tech stack, project structure, brand rules, compliance checks, templates. - [Contribute](https://freeappstore.online/contribute): How to become a creator and publish apps. ## Platform - [App Catalog](https://freeappstore.online/): Browse all published apps. - [Creator Console](https://freeappstore.online/app/): Manage your apps, deploy status, analytics. - [VibeCode](https://freeappstore.online/app/build): AI app builder in the browser. - [Pricing](https://freeappstore.online/pricing): Free vs Pro feature comparison and cost breakdown. - [Platform Source](https://github.com/freeappstore-online/platform): SDK, CLI, compliance, and backend source code. ## Optional - [Privacy Policy](https://freeappstore.online/privacy): Accounts, local and cloud app data, browser permissions, diagnostics, analytics configuration, and third-party services. - [Terms of Service](https://freeappstore.online/terms): MIT license required, free forever. - [Quality Reports](https://freeappstore.online/quality): Automated quality scores for every app. - [FreeGameStore](https://freegamestore.online/): Sister platform for free web games. - [ProAppStore](https://proappstore.online/): Separate paid platform; consult its own current docs and pricing.
