LynxPrompt

Self-hostable AI config management for teams and individuals

---

What is LynxPrompt?

LynxPrompt is a self-hostable platform for managing AI IDE configuration files — AGENTS.md, .cursor/rules/, CLAUDE.md, slash commands, and 30+ other formats. Deploy it on your own infrastructure and give your team a central hub to create, share, and standardize AI coding assistant configurations across every project.

Instead of manually writing configuration files for every project and every AI tool, use LynxPrompt to:

• Generate configs through an interactive wizard (web or CLI)
• Share blueprints through a private or federated marketplace
• Standardize AI behavior across projects with reusable templates
• Export to any supported format with one click

LynxPrompt is free and open-source. Self-host it for personal use, or deploy it within your organization to enforce coding standards, share institutional knowledge, and ensure consistent AI assistant behavior across your engineering teams. A hosted instance is also available at lynxprompt.com for those who prefer not to self-host.

Key Features

Universal AI Config Hub

Supports 30+ AI coding assistants — Cursor, Claude Code, GitHub Copilot, Windsurf, Zed, Aider, Gemini CLI, Cline, Roo Code, Amazon Q, JetBrains Junie, and many more. Write once, export to any format.

Blueprint Marketplace

Internal or federated marketplace for sharing AI configurations and slash commands within your organization. Browse, search, favorite, and reuse blueprints across teams.

Interactive Wizard

Step-by-step config generator available on both web and CLI. Auto-detects your tech stack, frameworks, and repo structure from GitHub/GitLab URLs. Supports template variables, monorepo hierarchies, and draft auto-saving.

Configurable Authentication

Flexible auth to fit your environment:

• OAuth — GitHub, Google
• Email — Passwordless magic link login
• Passkeys — WebAuthn biometric/hardware key authentication
• SSO — SAML, OIDC, and LDAP for enterprise identity providers

Optional AI-Powered Editing

Enable AI-assisted blueprint creation and editing with your own Anthropic API key. Entirely optional — works fully without it.

Full REST API + CLI Tool

Programmatic access for automation and CI/CD integration. Generate API tokens, fetch blueprints, search, and download via REST. The CLI (lynxp) mirrors the full web platform feature set.

Self-Hostable with Docker Compose

Single docker compose up to run the entire stack. PostgreSQL included. Auto-runs database migrations on startup. Toggle every feature via environment variables.

Quick Start (Self-Hosting)

# 1. Create a .env file
cat > .env <<EOF
NEXTAUTH_SECRET=$(openssl rand -base64 32)
ADMIN_EMAIL=your@email.com
APP_URL=http://localhost:3000
EOF

# 2. Download the self-host compose file and start LynxPrompt
curl -O https://raw.githubusercontent.com/GeiserX/LynxPrompt/main/docker-compose.selfhost.yml
docker compose -f docker-compose.selfhost.yml up -d

# 3. Open http://localhost:3000

That's it. LynxPrompt is running with PostgreSQL, automatic migrations, and email authentication enabled by default.

CLI

The CLI tool mirrors the web platform and works against any LynxPrompt instance. By default it connects to lynxprompt.com, but you can point it to any self-hosted deployment.

# Install
npm install -g lynxprompt

# (Optional) Point to a self-hosted instance — two ways:
lynxp config set-url https://lynxprompt.your-company.com
# or: export LYNXPROMPT_API_URL=https://lynxprompt.your-company.com

# Authenticate (opens browser on the configured instance)
lynxp login

# Generate AI config files interactively
lynxp wizard

# Pull a blueprint
lynxp pull bp_abc123

# Push local configs
lynxp push

# View current CLI configuration
lynxp config

The API URL is stored in the CLI config file (see lynxp config path). The LYNXPROMPT_API_URL environment variable takes precedence if set.

Also available via Homebrew (brew install GeiserX/lynxprompt/lynxprompt) and Chocolatey (choco install lynxprompt).
