The stack behind every tool here.

Four pieces are all it takes to build and run your own internal tools. It is exactly what we use.

01 Hosting

Netlify

Where your tool lives on the web: sites, forms, file storage and small serverless functions, deployed with one command.

Visit Netlify → 02 Your builder

Claude Code or Codex

The AI that writes, runs and fixes the code with you, inside your own folders. Pick one; both work with every tool here.

Visit Claude Code → 03 Servers

Hetzner

Low-cost servers for anything that has to run all day: bots, scrapers, schedulers and background jobs.

Visit Hetzner → 04 Code

GitHub

Where the code lives, with every change saved, so you can roll back, share it or open it up like we do.

Why we give it away

Most agencies guard their tooling. We would rather show our work.

If a free tool solves your problem, use it. If you would rather have the team that built it build the next one for you, that is what we do.

Want it built for you instead?
