Decision shortcut
- Single stack, one developer, $29 budget. Pick whichever pack matches your stack. Skip the bundle.
- Single stack, team of 5–20. The matching Commercial license. Skip the bundle until you cross stack boundaries.
- Multi-stack team, plus agent or MCP work. Studio Complete bundle. The break-even versus individual is 4+ packs.
- Just want to see what a Studio pack looks like. Read the free sample first.
What's not in any pack
- No scaffolders. The agent writes the code. The packs enforce how.
- No proprietary runtime. Just .mdc files and a CLAUDE.md. Drop them in, reload.
- No vendor lock-in. Cancel after the 14-day refund window and the rules are yours to keep.
- No analytics. The packs do not phone home.
Ready to pick?
