Requestly features

Send and debug API requests in seconds

Create and send API requests in seconds. Add methods, headers, and parameters, then check responses with full details with syntax highlighting and formatted JSON.

Organize your requests into collections and environments

Group related requests into Collections for easy navigation. Reuse variables and switch environments to keep your testing workflow clean and consistent.

Automate tests with scripts and variables

Add logic to your API flow using pre- and post-request scripts in JavaScript. Automate things such as adding tokens, setting timestamps, and validating responses, so you won’t have to do them manually every time.

Simplify with variables

Switch between dev/staging/prod instantly using environments. Use variables to replace static values and adapt requests to different environments instantly. Keep them global or limit them to a specific project - whichever works best for your setup.

Work locally or in the cloud with optional team sync

Your data stays on your device when working locally. Keep your projects private with local workspaces or collaborate with your team in the cloud when required. Git sync and role-based access make teamwork easy and controlled.

Import from Postman

Move your entire Postman collection and environment to Requestly with a single click. Enjoy a lightweight, fast, and open-source workspace that keeps all your APIs local and under your control. Start developing smarter and faster without losing any of your existing setups.

Every time I try to open it, I get: « No internet Unable to connect to Requestly servers. Make sure you're connected to the internet or try removing any active proxy. » Yes, I’m using a custom DNS, and a VPN, but it shouldn’t block… it should be the other way around.

Hi Universus, thanks for giving Requestly a try. Using a custom DNS and a VPN shouldn't cause this issue unless it blocks the access to Requestly servers. Please feel free to reach out to us so that we could help you diagnose the issue. https://www.browserstack.com/contact

Hey Théo — really sorry about that experience 😞 That’s definitely not what we aim for. Would you mind sharing a bit more detail on what specifically didn’t work or felt buggy? It would help us a lot to understand the exact issues you ran into. If it’s convenient, could you please raise an issue here with steps/screenshots (even brief ones are fine): 👉 https://github.com/requestly/requestly We actively track and fix issues there, and your feedback would directly help us improve. Thanks again for taking the time to try Requestly 🙏

Awesome App

The app won’t quit using force quit. Also I was searching for a tool that allowed me to store information from a request in a variable. This app allows the use of variables but you cannot update them based on responses. Edit: @Developer Thanks for following up, I could not find the resource needed, also the AI did not suggest the post-response-script feature. I would like to rate the app neutral, however there is no such option as I would like to review it further.
