doc0 - terminal-native documentation

A document0 product

A terminal-native documentation runtime. Browse any framework’s docs in a TUI, expose the same cache to your agent over MCP, and keep everything local. One config file. One cache. Zero servers.

$ npm i -g doc0

doc0 — zsh

01tui

A real browser, in your terminal.

Run `doc0 <id>` to open the Ink TUI: tree on the left, rendered Markdown on the right, forward/back history, `/` to search, `Enter` to open. Same layout for installed bundles and remote URL docs.

# Receive Stripe webhook events

Webhooks notify your server of asynchronous events. Configure an

endpoint, verify the signature, then return 2xx within 30 seconds.

## Forward events to localhost

$ stripe listen --forward-to localhost:3000/webhook

> Ready! Your webhook signing secret…

02mcp

Your agent runs the same CLI — over MCP.

`doc0 mcp` is a stdio MCP server. Four tools: find_docs, read_docs, grep_docs, list_docs. Most agent flows are a single find + single read. `doc0 mcp install --cursor` merges doc0 into `~/.cursor/mcp.json` in one command (Claude Code + Windsurf support coming).

Ran Read Docs in doc0

Stripe retries webhook deliveries with exponential backoff over 3 days when the endpoint returns non-2xx or times out.

Return 2xx quickly; queue slow work in a background job.
Verify signatures with Stripe.webhooks.constructEvent.

03local

One config file. You own every byte of it.

Everything doc0 does is driven by `~/.d0rc`. Point at your own registry fork, disable the community source for air-gapped networks, rebind every TUI key, tighten or loosen cache TTLs, or restrict MCP to installed bundles for a team setup.
