# Crow Nest Docs

> Crow Nest hosts the web apps people build with AI, behind sign-in, shared like a document, with a database, files, AI calls, outside APIs, live updates and server code built in. Every page below is Markdown.

## Get started

- [Crow Nest docs](https://docs.crow-nest.com/index.md): What Crow Nest is, how the pieces fit together, and where to start reading.
- [Quickstart](https://docs.crow-nest.com/quickstart.md): Connect your AI to Crow Nest, publish an app, and share it, in about five minutes.
- [How Crow Nest works](https://docs.crow-nest.com/how-it-works.md): Apps, addresses, versions, viewers and sign-in, workspaces, and what Crow Nest runs for you.
- [For AI agents](https://docs.crow-nest.com/for-ai-agents.md): How an AI agent should read these docs, use the Crow Nest MCP server, and behave when publishing for a person.

## Publish and share

- [Publishing](https://docs.crow-nest.com/publishing.md): Publish an app from your AI through MCP or from the terminal with the crow CLI, what gets published, versions and rollback.
- [Sharing and access](https://docs.crow-nest.com/sharing.md): The five ways to share an app, what viewers need to open it, company policies, search engines and AI crawlers.
- [Custom domains](https://docs.crow-nest.com/custom-domains.md): Serve an app on your own domain with a CNAME record, put all of a company's apps on one company domain, or buy a domain through Crow Nest at the registrar's price plus $1 a year.

## Build apps

- [crow.json](https://docs.crow-nest.com/crow-json.md): The reference for crow.json, the file at the root of a published folder that turns on data, files, AI, outside APIs, live updates and server code and sets their rules.
- [Data with crow.db](https://docs.crow-nest.com/data.md): Save and share JSON documents from the browser with crow.db, set who can read and write them, take entries from signed-out visitors, and watch for changes.
- [File uploads](https://docs.crow-nest.com/files.md): Let people upload images, PDFs and other files with crow.files buckets, and control who can see and add them.
- [Live updates](https://docs.crow-nest.com/live.md): Show changes to everyone looking at an app as they happen, with watch on collections and crow.live channels for messages that aren't saved.
- [AI calls](https://docs.crow-nest.com/ai.md): Call Claude, GPT, Gemini or an OpenAI-compatible model from an app with crow.ai, using a key you, your company or the app brings, with limits and costs you control.
- [Outside APIs and secrets](https://docs.crow-nest.com/apis-and-secrets.md): Call third-party APIs that need a secret key from the browser with crow.api, without the key ever reaching the page.
- [Server code](https://docs.crow-nest.com/server-code.md): Run your own code on the server for webhooks, private logic and SQL, with scheduled jobs, background tasks, logs and per-request limits.
