  • getd.io

    A free, online REST API builder that works with CORS. A Postman alternative without the native apps. Most Postman alternatives in the market today (including Postman) require downloading a platform-specific client app, or installing a Chrome plug-in. This is needed to provide full request support such as CORS. However, this approach has a few cons: - Setting up a new dev env requires downloading and installing app again. - App needs to be periodically updated / patched.
