Simple as a commit

Describe your Data

Create a config file on your GitHub repository and update it as your UI requirements evolve.

Use Git branches to have dedicated per-feature fake API.

github.com /org/repo/ .mockend.json 
{
  "User": {
    "name": { "string": { "minLength": 3, "maxLength": 10 } },
    "online": { "boolean": {} },
    "picture": { "regexp": "https://…" }
  }
}
Custom and powerful

Get random Data

Provide your own values or use our simple and flexible generators to have meaningful fake data.

The possibilities are limitless.

mockend.com /org/repo/ users
Instantly productive

Focus on UI

Get a fake REST or GraphQL API in seconds.

Everything you need: list, filter, sort, search, paginate, create, update.

Mock API everywhere: 

// REST CRUD
GET    mockend.com/org/repo/users?params…
GET    mockend.com/org/repo/users/<id>
POST   mockend.com/org/repo/users
PUT    mockend.com/org/repo/users/<id>
PATCH  mockend.com/org/repo/users/<id>
DELETE mockend.com/org/repo/users/<id>

// GraphQL endpoint
{
  users(limit: 5) {
    name
    online
  }
}
Integrated to GitHub

Perfect for Teams

Git branches for multiple fake API, pull requests to discuss and update your API.

Secure, Mockend can only access the config file and not the rest of your code.

Nothing to install, use your favorite tools: GitHub, VSCode, CodeSandbox, Terminal, …

# Git push to deploy a new fake API
$ git add .mockend.json
$ git commit -m "add new Product model"
$ git push

// New resource instantly available
fetch('https://mockend.com/org/repo/products')
