Native to the metal
No web views wrapped in a window. Real native apps on every platform we ship to — fast, quiet, and at home on the device they run on.
We forge native software for every screen you own.
The App Foundry is a small, independent studio building software that respects your machine, your privacy, and your time. We started on the Mac, we're on iPhone now, and we're expanding fast — Android, Windows and the web are next. Same standard on every platform.
The workshop
A studio with a standard, not a catalogue.
The Foundry exists to ship a handful of apps done properly — not a shelf of quick utilities, and not one platform's worth of them. Three commitments hold across everything we make, wherever it runs.
Safe by default
Software that touches your machine should earn your trust. Nothing destructive happens without informed, reversible consent.
Yours & private
Your files, keys, health data and configuration stay on your device. We collect as little as possible, and never sell your data.
Our apps
What we've forged.
Two shipping, more on the bench — and more platforms with them. This is where they'll appear.
Live Catalyst
Mission control for your Mac dev environment
Homebrew, pip, virtual environments, a broken toolchain, disk bloat, drive and battery health — even moving your whole setup to a new Mac. Every terminal chore becomes a few safe, reversible clicks.
macOS 14.6+ INSTALL →
Live Metapace
Every metric. Total privacy.
Calories, macros, weight, fasting, water and recipes — with the deepest South Asian food database anywhere, and a wellness intelligence suite that reads sleep, training and recovery. No account. No analytics. Everything on your device.
iOS 17+ INSTALL →
How the Foundry works
Made by hand, kept in good repair.
- 01
Built in the open where we can
Catalyst is free and GPL-licensed, source and all. Where an app can't be open, the reasoning and the data practices are — no black boxes either way.
- 02
Shipped, then sharpened
Small, frequent releases with real changelogs. Updates land quietly; you always know what changed.
- 03
Honest by construction
No dark patterns, no rented essentials, no data sold. Free where free is right, paid where paid is honest — and never a subscription for something that should have been yours.
Join the Collective
One server, with #catalyst and #metapace inside it. Share ideas, get early access, tell us which platform to take on next — and help us grow. A small studio moves as fast as the people backing it.
Behind the bench
Built by a community that actually uses the tools.
The App Foundry is a free software collective. Questions, bugs, or an idea for what the Foundry should build next? Join us on GitHub.
