Mount it.
Don't deploy it.
A separate deployment for every SaaS feature you rebuild is the wrong shape. Testimonials, live chat, a feedback board — these are features of your product, not products. Mount them as engines onto the app you already run.

Questions
- What is a Rails engine?
- A Rails engine is a miniature application that plugs into a host Rails app. It brings its own models, controllers, views, migrations and routes, and mounts at a path you choose — so it shares your database, your session and your deployment.
- Why mount an engine instead of deploying a separate app?
- A separate deployment means a second database, a second auth system and a second thing to patch. Mounting keeps one app, one deploy and one database, and the feature can read your existing user records directly.
- Can a Rails engine really replace a SaaS product?
- For features rather than products, usually yes. Testimonials, live chat, feedback boards, admin panels, analytics and feature flags all have mature mountable engines. Where an engine only covers part of what the SaaS does, this directory says so.
- How do I add an engine to the directory?
- Create an account and submit it with a repository link, a description, screenshots and the SaaS product it replaces. An admin reviews every submission before it goes live.
