Developer Tool to Build, Test & Debug Web Apps
"Requestly is an open-source platform for front-end developers with essential tooling & integrations that helps them write, test & debug their code 10x faster. Requestly reduces dependency on backend devs and environments for development & testing needs.
Using Requestly, devs can create mock, test, validate & override API responses, modify request & response headers, set up redirects (Map local, Map remote), and use Requestly sessions for faster debugging.
Requestly's frontend application provides a UI to manage rules, mocks, SessionBooks, user profiles and workspaces. It's built using React!"
