Open Mercato
Open Mercato - the AI-Engineering Foundation Framework.
AI code assistants generate code. They don't decide where it goes, how it should be layered, or whether it stays consistent across 30 or 50 engineers in the team.
Open Mercato is the open-source foundation framework that solves it:
- Architecture-aware AI harness - agents know where in the project to place code, not just how to write it, they are provided with autonomous skills for everything from adding data table, Design-System coherent forms to implementing whole features with unit and integration tests,
- Spec-first development - specs ship with the repo, AI output becomes reproducible
- Including AI harness and skills for human cooperation - code review, ticketing flow and debugging
- Ready-made CRM/ERP domain modules - start at 80% done
- Open-source, no lock-in - full code ownership, no per-seat pricing trap
- Teachable - the whole team enters AI-assisted dev, not just 1–2 seniors
End with „almost ready apps”. Ship it pro, ship it fast. We’ve got you!
Built for CTOs who have already deployed Cursor/Copilot and noticed it isn't enough. Built for developers who want to build professional business apps and backends without constantly checking their back.
Start with 80% done.
Buy vs. build? Now, you can have best of both. Use Open Mercato enterprise-ready business features like CRM, Sales, OMS, Encryption, and build the remaining 20% that really makes the difference for your business.
