Stop wasting hours explaining your Rails API to frontend developers. RailsMap automatically maps your routes, controllers, and models into beautiful, interactive documentation that everyone can understand.
Every Rails developer knows the pain. Your backend is powerful, but getting the frontend team on the same page feels impossible.
Frontend devs constantly asking about available routes, required params, and response formats. You spend more time explaining than coding.
You wrote docs once, then the API changed. Now nobody trusts them, and you're back to Slack messages and screen shares.
Every time someone needs API info, you have to stop what you're doing, dig through controllers, and piece together the answer.
New team members struggle to understand your data structure. They open migration files, check schemas, ask questions...
Install once, forget forever. Your API documentation stays in sync automatically.
Every route in your Rails app is automatically discovered and documented. HTTP methods, paths, constraints, and route names—all mapped instantly.
Database columns, associations, validations, and scopes are extracted automatically. Your data structure, documented without writing a single line.
Modern, responsive interface that developers actually want to use. Searchable, filterable, and easy to navigate. Looks great on any device.
Secure by default with environment variables. No database, no migrations—just set RAILS_MAP_USERNAME and RAILS_MAP_PASSWORD. Defaults to admin/password.
Run one command. That's it. No config files, no annotations, no comments. RailsMap reads your code and generates docs automatically.
Add a route? It's documented. Change a model? Updated automatically. Your docs are always current because they come from your actual code.
RailsMap reads your controller code and automatically documents every parameter—path, query, and body—with type inference.
A clean, organized view of your entire Rails API. No more digging through code.
No annotations. No YAML files. No manual work. Just install and go.

Seriously. Three commands and you're done.
Just one line. That's all you need to add.
This mounts the engine and creates the config. Set environment variables to customize credentials (defaults: admin/password).
Start your server and open the documentation URL. Login with default credentials: admin/password
rails doc:generate to export static HTML and host it separately.
authenticate_with config accepts any proc. Use authenticate_user! for Devise, or write your own custom logic — IP whitelisting, role checks, anything.
rails doc:generate to export static HTML to doc/rails-map/. You can then host it anywhere — S3, Netlify, internal wiki, etc.
Give your team the documentation they need. Install RailsMap today and bridge the gap between backend and frontend—permanently.
