What it does Steedos is a low-code platform that lets you define enterprise apps through YAML metadata rather than boilerplate code. It auto-generates APIs, UIs, and workflows from *.object.yml and *.page.yml files, with a runtime that supports MongoDB, PostgreSQL, or even flat JSON files. Think Salesforce’s metadata model, but open-source and container-friendly.

The interesting bit The project is mid-pivot: the v2.x “Steedos Platform” is still supported, but all future development is heading toward “ObjectStack” — a three-layer stack (ObjectQL for schemas, ObjectOS for headless runtime, Object UI for React/Tailwind rendering). The bet is that AI can write the YAML faster than humans can drag components, making “text-to-app” the new drag-and-drop.

Key highlights

• Database-agnostic metadata layer: same YAML deploys to MongoDB, PostgreSQL, or JSON files
• Auto-generated GraphQL and REST APIs for every metadata-defined object
• Schema-driven React UI via Tailwind/Shadcn, with escape hatches for custom components
• Built-in RBAC down to field level, plus workflow automation through YAML or TypeScript triggers
• Docker one-liner (steedos/steedos-community:3.0) or npx create-steedos-app to scaffold

Caveats

• The ObjectStack rearchitecture is incomplete; the README warns v2.x is supported but future work is on the new stack
• The comparison table cheerfully marks Salesforce as “hard to extend” and “cloud only” — your mileage may vary
• 1,557 stars suggests a modest community; enterprise-grade claims vs. actual battle-testing is unclear from the README alone

Verdict Worth a Docker spin if you’re building internal CRUD-heavy tools and want a Salesforce-like metadata model without the licensing bill. Skip it if you need a mature, stable platform today — the pivot to ObjectStack means the ground is still moving.
