Developer tools that ship faster.

Mac apps, open-source developer tools and games, built by engineers.

EasyHomebrew

Supply-chain hygiene for your Mac. Every installed Homebrew package is checked against a live CVE database, a menu-bar agent watches for new advisories, and a complete native package manager sits underneath.

  • CVE scanning of installed packages against a live advisory database
  • Menu-bar agent that watches for new advisories on your schedule
  • Services manager with live log tailing, and Brew Doctor one-click fixes

Contain

One window for the windows you already have open on your Mac. Each one gets a tab, and letting it go puts it back at the exact position, size and screen it came from.

  • One tab per window, not per app — three documents from one editor are three tabs
  • Release a window, or quit, and everything goes back exactly where it was
  • €6 once for three Macs — no subscription, no account, lifetime 1.x updates

Practical UV

uv inside VS Code. Outdated packages and known vulnerabilities are flagged in the file you already have open, and a pip project converts to uv in one click.

  • Outdated dependencies and known CVEs flagged in the file you already have open
  • uv.lock-accurate findings — the version you install, not the range you declared
  • One-click pip → uv conversion in VS Code, or one npx command in any terminal

WizLook

Quick Look for the files your Mac leaves blank. Press Space in the Finder on an Excalidraw drawing, a Jupyter notebook, a canvas, a JSON file or source code in 61 languages, and see what is inside.

  • Finder previews for Excalidraw, Jupyter notebooks, JSON Canvas, JSON, YAML, TOML and Markdown
  • €6 once, for one Mac, with no subscription
  • Read-only by design — it never changes a file, and never runs what is in one

What we are building toward

AI you can check
We want AI you can hold to account: running on your own machine, giving the same answer twice, and keeping its reasoning close enough to the surface that you can disagree with it. Where a question has an exact answer, we would rather compute it than ask for one.
Owning the mechanism
We would rather understand a thing than depend on it. The engines under our tools are written from the format up, with almost nothing pulled in, because the parts we wrote ourselves are the parts we can fix, explain and keep running for years. It is the slower way to build, and it ages far better.
Privacy first
The strongest privacy guarantee is a product with no reason to collect anything. Ours are bought outright, which keeps the incentives simple: your files stay on your disk, your work stays yours, and privacy is the default state rather than a setting you have to go and find.
Fair pricing
Every tool we sell follows one fair-pricing policy: a price set so that the tool is accessible to everyone who could use it, and ends up in daily use rather than on a shelf. One fair payment, and it is yours. Fair is not the same as cheap. It is the price at which a tool reaches the most people, and we would rather be used by many than paid the most by a few.
It works on what you already have
Our tools meet your work where it already is — the windows already open, the files already on disk, in formats other software wrote and other software can still read. A tool should fit around the work that exists, rather than ask the work to rearrange itself around the tool.
Research that reaches somebody
A good idea about software deserves both halves: an implementation people can actually use, and the evidence standing next to it. We build our experiments as products you can hold, and publish the numbers behind them where anyone is free to check the claim.
