Send a request, read the answer, save it for next time.

A browser tool for developers and testers to build and send API requests. Organize requests in collections, switch between environments and share them with teammates, with nothing to install. Included in every Nubo plan, at one per-seat price for all apps.

Do my scripts have network access?
No. Scripts run in an isolated sandbox with no network access and stop after a timeout.
