UrlEdge
Serverless Mock Engine

Instant Mock APIs & Static Endpoints

Frontend ready but backend isn't? Spin up a JSON Mock API in seconds. Host config files, ads.txt, or maintenance pages directly on the global edge.

Stop Waiting for the Backend

Why delay your frontend shipping date? Hardcode your expected JSON response at the edge and start building immediately. No server setup, no deployment pipelines.

Mock JSON APIs

Simulate your production API. Define status codes (200, 404, 500) and headers to test how your app handles errors.

No-Code Maintenance

Backend down for upgrades? Switch your DNS to serve a static, beautiful HTML 'Under Maintenance' page instantly.

IoT & App Config

Host `config.json` or `remote_flags.json` for your mobile apps or IoT devices. Update values globally in <1s.

Solves the "Root Directory" Problem

Host .well-known Files Without Accessing the Server

Using Shopify, Wix, or Webflow? They often won't let you upload specific verification files to the root directory. UrlEdge solves this. Create a route for /ads.txt or /apple-app-site-association and serve the raw content from our edge.

ads.txt / app-ads.txt

Limits, CORS, and Headers.

URLEdge allows you to define custom response headers. Simply add `Access-Control-Allow-Origin: *` to your response configuration to allow requests from any frontend domain (localhost or production).
