rtzen.work
We assemble production software from pre-built, tested modules. The agent writes only the part that is actually your business.
The problem
01
Non-deterministic
Same prompt, different code. Nothing accumulates.
02
Wrong where it matters
Plausible auth is still broken auth.
03
Humans still test it
Generation is cheap. Verification is not.
Demo in minutes. Production in months.
The insight
Don't make the agent an author. Make it an integrator.
What we've built
73
modules in the catalog
30
built out and versioned
707
automated tests
11
business categories
Fix a module once and every app built on it upgrades. Quality compounds instead of resetting.
The business
Against a stack billed per seat, per tool, forever.
Published
30 modules versioned on the registry. 707 tests every release.
Deployed
Pick modules, get a running app on its own live URL.
Composable
A reference app installs the published packages, not the source.
