Capabilities

Everything a backend developer actually wanted

Built for developers who are tired of writing throwaway mocks. Paste a URL, get a server.

Instant mock server

From spec to running server in seconds. ClonePoint generates a full Express mock that returns realistic sample data for every endpoint.

{}

OpenAPI 3 & Swagger 2

Paste any OpenAPI 3.x or Swagger 2.0 spec — JSON or YAML. ClonePoint auto-detects the format and parses every endpoint, parameter, and schema.

$_

cURL templates for every endpoint

Copy-pasteable cURL commands for every endpoint, against both the source API and your mock. Ready to drop into scripts or docs.

📦

Download the Express project

Grab the full Express project — server.js, package.json, README — ready to run locally or deploy anywhere. It's your code.

Workflow

FAQ

Common questions

What spec formats are supported?
OpenAPI 3.0, 3.1, and Swagger 2.0 in both JSON and YAML formats. If it's a valid spec, ClonePoint can parse it.
How long do hosted mocks stay live?
Mocks stay live as long as your account is active. They're accessible via a unique URL with your API key — perfect for development, testing, and demos.
Can I customize the mock responses?
Yes. Download the Express source, modify the handlers however you want, and redeploy. You own the generated code.
What's the difference between ClonePoint and DevBook?
DevBook is your team's API workbench for building, testing, and managing API requests. ClonePoint is a tool for cloning entire API specs into mock servers. They complement each other — use DevBook to test against your ClonePoint mocks.
Is there a free tier?
Every account starts with a 14-day free trial, no credit card required. After that it's $15/month — cancel anytime.
