spec → live mock · no account

Turn any API spec into a live mock in seconds.

Paste an OpenAPI spec, a doc table, or plain English. AI generates a validated mock config and publishes it to a live URL — instantly.

Live beta — some features are still in progress. Have feedback or hit a rough edge? contact@mocc.dev

mocc.dev — quickstart
// how it works
01
Paste any spec
OpenAPI, Swagger, a doc table, a PDF, or plain English — all accepted.
02
AI builds the mock
A validated mimicore config is generated with typed routes and transforms.
03
Hit your URL
Your mock is live at {slug}.mocc.dev — shareable, versioned, hot-reloadable.
// features
~3s
Zero-friction start
Anonymous quickstart. Paste a spec, get a live URL in seconds — register later to keep it.
AI
Understands messy input
Partial specs, PDFs, HTML docs, plain English — not just clean OpenAPI 3.x.
{}
Editable, versioned config
Own the JSON. Every save is an immutable version with full undo/redo history.
Subdomain per API
Each mock gets {slug}.mocc.dev. Share a URL, not an IP and port.
Postman · OpenAPI · Swagger
One click exports your mock to a Postman collection or OpenAPI 3.0 / Swagger 2.0 spec — no AI, every plan.
Real-time traffic
Prometheus metrics streamed from the engine — watch requests hit your mock live.
// who uses it
FRONTEND
Solo dev
Backend isn't ready. Needs a shareable mock for every feature sprint.
BACKEND
Full-stack
Flaky integration tests against third-party APIs. Wants deterministic fixtures.
QA / TEST
Test engineer
Needs controllable, repeatable responses. Staging isn't controllable.
TEAM LEAD
Architect
Team blocked on each other's contracts. Wants shared mock infra + SSO.
