// what you get

An app you can trust in production

Not code to copy: a rulebook your AI agent follows, so every part of your app is built the proven way.

stable

Built on proven tech

Go, Postgres and boring tools with long track records. Every version is pinned, so an update never breaks your app overnight.

tested

Tested before it ships

Unit, integration and UI tests, with 99% coverage enforced. A change that breaks something never reaches your users.

secure

Secure from day one

Threat model, sign-in, input checks, rate limits and privacy are in from the first commit, not patched in after launch.

released safely

Releases without fear

Separate dev, stage and prod. Repeatable deploys, a way to roll back, and backups you have actually restored.

watched

You hear about problems first

Clear logs, alerts and dashboards, so you know something broke before a customer tells you.

fast

Weeks, not months

One stack and one way to do each thing. Your agent builds instead of debating basics, and you skip the rewrite after launch.

Questions

Is it really free?

Yes. Fill in the form on this page and it's yours, under the MIT license. Use it on any project, including commercial ones.

Do I need to be a developer?

No, but you should be comfortable in a terminal and with an AI agent such as Claude Code. The agent does the heavy lifting; the playbook tells it what good looks like.

I've already started my app. Is it too late?

No. Ask your agent to align the project with the playbook. It closes the gaps step by step instead of rewriting everything.

Can you help me apply it?

Yes. In ProCode Extended you apply it to your own app with me and finish with it live in production. Or book a consultation.
