How it works
Pick. Install. Grow.
Pick a tool
Browse the catalog; every product page shows a live terminal demo and the exact install command.
Install the free edition
One command — installer script, ketch, Homebrew or your package manager. The open-source edition is the full tool.
Add Pro per tool
Only for the tools your team relies on, on top of the same binary. Placeholder
Why these tools
Small, local, accountable.
One binary each
Written in Rust and shipped as a single native binary for macOS and Linux; ketch runs on Windows too.
Local first
Ledgers, archives and installs live on your machine; export telemetry only if you choose.
Measured and verified
rtok records every saving, cox records every request’s cost, ketch checks every checksum.
Same licensing
GPLv3, royalty-free or commercial — your choice, for every tool in the catalog.

FAQ
Questions, answered.
What is free, and what would I pay for?
Every tool’s open-source edition is free — the full binary, no feature gates. Pro tiers (placeholder) would add team features on top, priced per tool.
How are the tools licensed?
All tools in the catalog use the same licensing. You can use each one under any of the following, at your choice:
- GNU GPLv3 — free for open-source applications on any platform, including embedded systems.
- Royalty-free license — free for proprietary desktop, mobile and web applications, as long as you disclose that your application uses the project. Embedded systems are not covered.
- Commercial license — for proprietary applications, including embedded systems, without the attribution requirement.
What data leaves my machine?
The open-source tools run locally and keep their ledgers on disk; rtok and cox export telemetry only if you point them at an OTLP endpoint. Pro data handling terms are a placeholder and will be published before any launch.
Can I self-host?
The free editions are local binaries — there is nothing to host. A self-hosted Pro option is a placeholder in this MVP.
How do I upgrade a tool to Pro?
Keep your existing install; Pro (placeholder) is designed to connect on top of the same binary, one tool at a time.
