Mock any REST API.
Before the backend writes a line.
Define routes, generate realistic JSON payloads, and connect your frontend to a persistent HTTPS mock server in seconds.
Active
developer community
Instant
live mock URLs
5 HTTP Verbs
GET, POST, PUT, DELETE, PATCH
Zero Cold Start
Persistent PostgreSQL storage
From contract to integration in three steps.
Built to eliminate dependencies so frontend engineers can develop without waiting on backend sprint tickets.
Define Endpoint Contract
Select HTTP verbs (GET, POST, PUT, DELETE, PATCH), custom path, status codes (200, 404, 500), and custom response headers.
Shape Payloads & Latency
Edit JSON directly or prompt the AI engine to generate realistic mock collections. Inject simulated network latency to test UI skeletons.
Plug into Client App
Copy the persistent HTTPS URL straight into your React, Next.js, Vue, or Flutter codebase. Zero cold start, 100% predictable.

All the controls required to simulate edge cases, test network hiccups, and share contracts with teammates.
Complete HTTP Verbs
Support for GET, POST, PUT, DELETE, and PATCH. Return exact response headers, cookies, and HTTP status codes (200, 201, 400, 404, 500).
Dynamic Latency Simulation
Inject artificial network delay (from 0ms up to 2,000ms) to inspect your React Suspense fallbacks, loading spinners, and offline states.
Workspaces & Public Docs
Keep your endpoints grouped by project or microservice. Generate shareable public documentation pages with a single toggle.
Straightforward pricing for developers.
Start completely free. Upgrade only when your project needs expanded workspace capacity.

Frequently asked questions.
Everything you need to know about mocking endpoints with VeloMock.
Is VeloMock a real hosted API endpoint?+
Yes. Every mock endpoint gets a globally reachable HTTPS URL that returns your exact JSON payload, custom headers, and status code with persistent PostgreSQL storage.
Can I simulate network latency and slow connections?+
Yes! You can configure custom delay in milliseconds (e.g., 200ms or 1500ms) to thoroughly test your frontend loading skeletons, optimistic UI, and error boundaries.
Can I use it without AI generation?+
Absolutely. AI generation is an optional accelerator. You can write, format, and edit standard JSON payloads directly in the editor.
What happens when I hit the Free tier limit?+
All your existing active endpoints remain live and reachable. Upgrading to Pro unlocks 100 endpoints, workspaces, and priority generation limits.
Can I self-host VeloMock on my own VPS?+
Yes. VeloMock is built with complete Docker and Docker Compose support and can be deployed to your own private server via Coolify or Docker.
