6 Apps I Built With Claude Code
Instead Of Paying For.

You commented BUILD. Here are all 6 prompts, the folder structure, and my CLAUDE.md. Everything you need to cancel $4,236/yr of SaaS and own it forever.

You commented BUILD. Here's everything I used to replace $4,236/yr of SaaS in one weekend.

How this works: Each app is a prompt you run in Claude Code. You own what gets built. No subscriptions. No per-seat pricing. No data leaving your control.

The CLAUDE.md template and file structure are at the bottom. Start there if you've never used Claude Code before.
