Auto reloads Rails applications when assets or views have changed

Realtime debug dashboard for Rails applications

A Rack middleware captures object allocations per request using GC.stat diffs and stores them in a thread-safe ring buffer. Results are served through a mountable engine with a sortable, filterable dashboard — filling the gap between the memory_profiler gem and having nowhere useful to view results in a Rails app.

RailsNexus is an extensible operations and administration console for Rails applications.

Build reactive, real-time UI components that automatically re-render server-side when subscribed models change. Uses ViewComponent, Turbo Streams, and ActionCable to keep your UI in sync without writing custom JavaScript.

This gem helps Rails apps implement real-time like/unlike functionality on polymorphic models with Turbo Streams broadcasting.

Recourse adds a `recourses` method to config/routes.rb. One line draws the routes, controllers and views needed to browse and edit a resource, with no files added to the host app. Any controller, view or partial can be overridden by defining it in the app.

A Rails engine that lets a signed-in person pin notes to elements of any page: where on the page, what was there, what should change. Notes are read back by the host app (or its agent), resolved with one line, and the line shows up on the page.

Reviewkit is a mountable Rails engine for rendering Git-like code diffs, persisting threaded line comments, and embedding review workflows into host apps.

Every page of a Rails app opens as a window in endlessly scrolling column strips, one strip per workspace. Pages say how they want to be shown (size, modal, full width, workspace, reuse key); ⌘K and a drop-down terminal run the same fuzzy-matched command tree; a keymap with a configurable modifier (⌘ in a native shell) and optional Blender-style hover keys drive the windows. Ghostty colour themes and Unsplash wallpapers included. The host app keeps its own controllers and views.
