Latest reviews
Honestly, I never thought I'd be able to implement the various features I needed directly on the website with zero knowledge. I'm extremely pleased with the app's performance and thank the developers for such a great solution!
Very helpful extension
is cool but modify api response being paid is such a pain
Works pretty well. can add multiple API responses and update and use whenever it requires. Very good and recommended.
Works great. Pretty easy to use interface, the dark mode make it super easy to read, the flow of adding new scripts and to test some ideas is spot on.
Awesome tools so far. Easy to use and many logics that can be used
easy to use, even for an old man trying to get back initt
Awesome extenstion, very good and recommended.
Very helpful tool for API development work This tool has been really useful for my daily work. I mainly work with APIs, React frontend, and Python backend for AI/ML projects. Requestly makes it easy to test API requests and responses without changing my code. I can modify headers, test different request payloads, and see responses quickly. It saves a lot of time when debugging issues between frontend and backend. The interface is simple to use and does what I need. Highly recommend for developers working with APIs and web development.
Helpful to test API failures
Nice to do some dynamic changes to API responses!
Have been using Requestly for years and it is important for my daily software engineering work. can't recommend more.
Good extension for developers and QAs
I use Requestly all the time, mostly for redirects. It's super convenient, reliable, and has clean, beautiful interface
Helpful for mock data!
excellent
Proper pro tool for mocking api responses and delays, much much easier than chrome overrides and way faster to adjust and manage
Requestly makes debugging APIs and modifying network requests a breeze. Nice plugin
Requestly makes debugging APIs and modifying network requests a breeze. Huge time saver for my workflow!
Nice Extension
very easy to use
Their paid plans are insane. When I first got the notification to upgrade I was reluctantly going to pay $8 a month, but then I saw that's limited to 5 rules??? What? So greedy
Perfect!
goodοΌvery very good
Great for debugging and modifying API responses to speed up development and testing
Great for debugging, modifying network calls, API responses, Params! Easy to use UI !
Great tool for debugging and modifying network calls. The standalone app + chrome extension is a plus.
Good tool for Dev recommended it
This Tool is Very helpful for Developers. Here we can Modify the Request as per our need . and the best Part its Right there in your Browser and Comes along with you if you Switch MAchines , unline Fidler or Charles. Good Work Team.
Helpful for debugging network issues
Best tool to intercept queries, modify them.
very useful tool for web development.
The tool is great, aggressive payment option is not
Great tool, worth to try!
Great tool
Very good, I hope there will be a free version soon
Very easy to use and it works as expected
Great tool
Great tool, I use it mostly every day. It helps a lot for modifying my test cases.
Very handy tool for frontend QA, testing and development overall
Can't say enough great things about this tool. We have a ton of complex data at work. Whether it be complex user data, specific error scenarios that just don't happen that often, or anything else I need from an API to prove to myself that something on the UI is working correctly, I always turn to Requestly to get me through it!
Very handy tool for frontend development!!
Useful tool for the QA purposes to modify BE responses
I use it to mock API calls to my servers. Sometimes I don't have a service running locally or the data that I have is not good enough for a complex page to render as expected. Here is where Requestly comes in. I mock responses with data that I want to have in my front end, and I do not need to worry about bad data in database, or an API that is not functioning correctly. I can mock headers as well during app's request. It is super useful for front end development. Responses can be dynamic as well, such as :id that is returned from the API. Solved my pain working with microservices and bad local data!
Love it so much! best in the game for dynamically modifying api response.
I am in love with this app it helps me out so much i use it everyday this may seem fake but its just so good.
For my use case 5 stars. A grocery store website that I access frequently was having issues with calls to a particular server timing out. I discovered another server without this timeout issue and used Requestly to redirect calls to this alternate server.
this is a great tool to unblock development, i need to bypass backend team for some time in a fast an efficient way and requestly gives me that
Super plugin
Very useful, just lack the variable feature, where I can add the value in a variable and use it across various rules like headers etc, other than that very user and powerful tool
