JSON Mock Server
Hosted JSON Mock Server for Developers
A JSON mock server provides API-like responses while your application is under development. Forge API hosts those responses online, removing the need to install local server packages or keep a development machine running.
No backend server setup required.
✓
No local server installation or configuration.
✓
Access endpoints from multiple devices and environments.
✓
Share working mock URLs with teammates and clients.
✓
Manage custom JSON responses from one account.

3
Share or integrate
Use the hosted URLs locally, in previews, test environments or demonstrations.
Use cases
Built for practical development workflows
Remote development teams
Share the same mock API endpoints across different machines and locations.
Preview deployments
Connect staging and preview applications to a publicly accessible mock API.
Client demonstrations
Demonstrate application features without exposing local development servers.
Frequently asked questions
Questions about json mock server
How is a hosted mock server different from a local one?
A hosted mock server is available through the internet, while a local mock server normally runs only on a developer's computer.
Do I need to install anything?
No. Forge API hosts your configured endpoints and provides HTTPS URLs.
Can teammates use the same endpoint?
Yes. Anyone with the endpoint URL can call it, subject to the access rules and limits of the service.
