Ferrum

Every Ferrum app

Ten native macOS apps, written in Rust and drawn on the GPU. All of them are free and in alpha, and Ferrum Launcher installs any of them and keeps it up to date.

Write it, commit it, run it, query it

The four apps most of a working day happens in.

Ferrum Editor

Code editor Alpha

A small, hackable code editor written from scratch in Rust and configured in plain TOML.

More about Ferrum Editor
  • Tree view, tabs, split panes, a fuzzy file finder and a command palette
  • Multi-cursor editing, regex find and replace, and find in files that respects .gitignore
  • Completions, problems and go to definition for Rust, Go, TypeScript and JavaScript
  • A built-in terminal, ⌘B builds, and Git staging in the sidebar
  • CI and Logs pages: GitHub Actions runs, and live logs of dev servers and containers

FerrumGIT

Git client Alpha

A native Git client with a commit graph, line staging and per-project SSH profiles.

More about FerrumGIT
  • A commit graph with branches, tags and your uncommitted work on top
  • Stage, unstage or discard one hunk, or only the lines you select
  • Side-by-side diffs, file history that follows renames, and blame
  • GitHub and GitLab pull requests: review, check out, create and merge
  • Undo for commit, amend and checkout

FerrumTerm

Terminal Alpha

A GPU terminal whose sessions live in a server, so closing the window stops nothing.

More about FerrumTerm
  • Sessions, tabs and splits that keep running in a background server
  • The fterm CLI starts, splits, types into and reads any pane, with --json output
  • An agents sidebar shows when Claude Code or Codex is working, done or blocked
  • SSH hosts from ~/.ssh/config in one click, and port forwards that keep running

FerrumData

Database IDE Alpha

A local-first database IDE for PostgreSQL, MySQL and MariaDB, SQLite, SurrealDB, MongoDB and Redis.

More about FerrumData
  • Run the statement under the cursor and stream it into a typed results grid
  • Sort the grid, keep a query history, and export to CSV or JSON
  • Browse tables with their columns and indexes, and Redis keys with their TTL
  • Read-only profiles, a confirmation before writes on production, and passwords in the keychain

Tools for the rest of the job

APIs, containers, ports, secrets, and the small conversions in between.

FerrumAPI

API client Alpha

A native, local-first API client with the Postman basics, minus the bloat.

More about FerrumAPI
  • Every HTTP method; JSON, form, multipart and binary bodies; Basic, Bearer or API key auth

FerrumKit

Developer utilities Alpha

The small conversions you would look up on random websites, in one native window that works offline.

More about FerrumKit

  • Start, stop, restart or remove, and bring a Compose project up or down
  • Live logs with search, and a shell in the container through FerrumTerm

FerrumPorts

Port inspector Alpha

Every listening port with its process and project, and a confirmed way to stop it.

More about FerrumPorts

  • Stop a process after a confirmation that shows its full command
