How it works.
Eight workflows explained.

From mock APIs to serverless functions — every workflow has its own interactive step-by-step guide.

Core Platform

Create & write function

Use the built-in Monaco editor with TypeScript support. Import shared layers for auth, DB helpers, and more.

getUsers.ts— Modified

1export const handler = async (req) => {

2 const users = await db.query(

3 'SELECT * FROM users'

4 );

5 return Response.json(users);

6};

Test with payloads

Inject JSON payloads and see the response in real-time. Built-in test runner validates before deploy.

Test Runner

POST /api/invoke/getUsers

{"limit": 10, "offset": 0}

200 OK42ms

[{"id":1,"name":"Alice"},{"id":2,"name":"Bob"}...]

Publish & get live URL

One-click deploy. Your function gets a live URL instantly with auto-scaling.

Built for teams.
Invite, share, control.

Collaborate on mock APIs and serverless functions with role-based access, project sharing, and granular visibility controls — all zero-config.

Invite by Email

Add team members with one click. Existing users are added instantly; new users get an email invitation to sign up.

Shared Projects

Assign any project to a team. All members see it in their dashboard and can invoke all APIs and functions inside.

Access Control

Two-tier visibility: set projects to Private, Public, or MoqAPI Users. Override per-endpoint with Inherit / Private / Public.

API Key Auth

Every project gets a unique API key. Pass X-API-Key in any HTTP request — perfect for CI pipelines and external callers.

Frequently Asked Questions

Everything you need to know about the moqapi mock API platform.

moqapi.dev is an all-in-one mock API platform for developers. Import OpenAPI, GraphQL SDL, or WSDL specs and get live mock endpoints in seconds — with AI-powered data seeding, stateful CRUD, chaos testing, webhooks, serverless functions, and cron jobs. No infrastructure setup required.

Postman mock servers require manual response setup and are limited to REST APIs. moqapi supports OpenAPI, GraphQL, and SOAP/WSDL specs out of the box, generates realistic data with AI, and includes built-in serverless functions, webhooks, chaos testing, and cron jobs — all on a free tier with zero config.

Yes. moqapi supports OpenAPI 3.x (including 3.1) and Swagger 2.0 specs. Import your YAML or JSON spec file and moqapi will automatically generate endpoints with smart path matching, query filtering, and spec-defined error responses.

Absolutely. Paste your GraphQL SDL schema and moqapi creates a working GraphQL endpoint with queries, mutations, and relationship resolution handled automatically. AI data seeding generates realistic response data matching your schema types.

Yes — moqapi offers a free tier that includes mock API creation, OpenAPI/GraphQL/SOAP import, AI data seeding, serverless functions, webhooks, chaos testing, and cron jobs. No credit card required to get started.

moqapi uses Google Gemini to generate context-aware mock data that understands your schema. Instead of random strings and numbers, you get realistic names, addresses, product descriptions, and domain-specific values that match your resource definitions.

Chaos testing lets you inject random HTTP errors (400, 404, 429, 500, 503) into your mock API at a configurable rate. This helps you stress-test your frontend error handling, retry logic, and loading states before hitting production — catching resilience issues early in development.

Yes. moqapi supports team workspaces where you can invite teammates by email, share projects, and control access with Private, Public, or API-key visibility settings. All team members can collaborate on mock APIs, functions, and webhook configurations.
