LynxPrompt is a self-hosted web app that turns one set of AI coding rules into the file each tool reads: AGENTS.md, CLAUDE.md, .cursor/rules/, Copilot instructions, 30 rule-file formats in all, plus slash commands for six of them. A wizard writes the rules from your stack, blueprints let a team share them with variables, and the lynxp CLI and the VS Code extension put the files into every repository. Run it with Docker Compose or the Helm chart, or try the hosted instance at lynxprompt.com first.

Features

• One set of rules becomes the rule file of 30 tools: AGENTS.md, Cursor, Claude Code, Copilot, Windsurf, Zed, Aider, Gemini CLI, Cline, Roo Code, Amazon Q, JetBrains Junie and more, plus slash commands for six of them.
• A 12-step wizard on the web or in the terminal builds the rules from your project, stack, commands, code style and boundaries; lynxp analyze reads an existing repository first.
• Blueprints carry [[VARIABLE|default]] placeholders, so one blueprint fits many projects.
• Each blueprint is private, shared with a team or public; teams get their own page, and federation shares public blueprints between instances that join.
• Hierarchical AGENTS.md for monorepos, managed from the dashboard, the CLI and the API.
• The lynxp CLI (19 commands: wizard, check, analyze, convert, diff, pull, push, search and more) and the VS Code extension work against any instance.
• Sign in with a magic link, passkeys, GitHub or Google OAuth, or SAML, OIDC and LDAP SSO; each is one environment variable.
• Optional AI editing with your own Anthropic API key; off by default, everything else works without it.
• Docker Compose or Helm, PostgreSQL included, migrations on start, every feature an environment variable.

Quick start

curl -O https://raw.githubusercontent.com/GeiserX/LynxPrompt/main/docker-compose.selfhost.yml -O https://raw.githubusercontent.com/GeiserX/LynxPrompt/main/docker-compose.mailpit.yml
(umask 077; printf 'NEXTAUTH_SECRET=%s\nDB_PASSWORD=%s\nADMIN_EMAIL=you@example.com\n' "$(openssl rand -base64 32)" "$(openssl rand -hex 24)" > .env)
docker compose -f docker-compose.selfhost.yml -f docker-compose.mailpit.yml up -d

Put your own address in ADMIN_EMAIL, open http://localhost:3000, sign in with it, and read the sign-in link at http://localhost:8025 (Mailpit, a local mailbox for trying it out); the dashboard opens and that account is the superadmin. For a real deployment set the SMTP_* variables in .env and drop the Mailpit file; the image is amd64 and runs under emulation on ARM. Helm, the CLI and the other install channels are in Getting started.
