Give your ideas
real data.

Describe your data model and Zero-1 conjures live REST endpoints with realistic records, automatic FK wiring, and propagation. No database, no config, no build step.

z1 — mock api engine

The data should look as real
as the idea.

Every frontend has the same dead time: somewhere early in the project you spend a day wiring up a throwaway API. Fake routes, hardcoded JSON, env vars pointing nowhere. You know none of it survives the sprint.

Zero-1 eliminates that entirely. Describe your data model the way you'd explain it to a colleague and in under two seconds you have a live server: realistic records, working filters, pagination, automatically wired foreign-key edges, and propagation that keeps denormalized copies in sync.

The schema evolves as you do. A single sentence adds a field, renames it, and tells you whether that change would break a reference before it does. Chaos injection, OAuth 2.0, header guards, JWT scoping — all one prompt away.

One AI call per intent. Your key, your cost, your data. Everything else — generation, CRUD, filtering, propagation — runs locally with zero API calls. Zero-1 is as fast as your machine.
