  • (2023-01-28) missthesky: 这是我遇到的最好用的网络请求类chrome插件
  • (2023-01-26) Ross Comer: Great functionality and amazing support. I ran into a problem with the Addin and the engineering team reached out to figure out a solution. They took the time to replicate the issue as well as provide alternative workarounds. At the same time, they taught me some tricks that eliminate the need for some other addins so I can just run this and not others.
  • (2023-01-25) Michael Kay: Really powerful. Been incredibly helpful in development and testing
  • (2023-01-13) Romain SAILLANT: Absolument indispensable à tout QA Analyst !!!!

  • (2023-01-12) Kenton deAngeli: A great tool for debugging web applications. Very useful for finding tough bugs.
  • (2023-01-12) Максим Дьяченко: I needed to change the API response to test how a specific value will be processed by frontend code I watched 4 minute video and it was enough to complete the task I google before that and all solutions involved a lot of coding, which I didn't want to do because it would be time consuming, and with requestly I saved quite a but of a time
  • (2023-01-03) Jason Reiche [RICH]: Saves me tons of time in development, testing, and diagnostics. I'm not sure how I'd do my work efficiently without it.
  • (2023-01-03) Sojib Belal: Been using it for 1y+ and my experience is very good.
  • (2022-12-29) Akshay Charwekar: Really helpful extension. Easy to use yet powerful.
  • (2022-12-28) Mano Mano: Nice to work
  • (2022-12-27) Sahil Gupta: Awesome Extension. Helps me a lot daily in testing.
  • (2022-12-23) pradeep jaiswal: Requestly comes as savior whenever adobe platform debugger shows a glitch in launch library override. I used Requestly for redirect and mockup file server and it really helped me in dev and debugging. The interface is easy to use and creating a rule one one machine and accessing it from different machine makes it awesome.
  • (2022-12-23) David Major: Very helpful for development!
  • (2022-12-22) ML: Requestly is user-friendly, brilliant and easy-to-use. I use it on an daily basis and it makes my work easier. After using other tools like Charles - Requestly is a nice new breath of air that I highly vouch for. Apart from the tool being amazing - the support from the Requestly team is phenomenal with them always going above and beyond for their clients.
  • (2022-12-22) Armaan Ahluwalia: Have used this tool at 2 different companies now - At the first, we used it to be able to inject our local bundles on third part websites. Recently, I tried using Postman mock servers but couldn't get it to work ( super confusing UX and lots of CORS issues). I thought I would give requestly mock servers a try since I'd used it before - to my delight the mock servers were so simple to set up and use I got it working within 2 minutes. Highly recommend requestly to all companies looking to mock APIs while doing front-end development before the backend is ready. Big up requestly team!
  • (2022-12-20) John Fraser: This tool has been instrumental in delivering our code to production on time. The ease of use has allowed us to develop the frontend application against an API concurrently with the backend work. It has also saved testing time by allowing the frontend to process edge cases very easily. Highly recommended!
  • (2022-12-17) Patricia rios: raro me funciona en mi computadora pero en la otra compu los instale para windows 7 simu y no me funciona que arreglen eso porfa

  • (2022-12-01) 未陈: why open “only in the desktop app” again? I don't want to download the desktop app,this will open a global proxy.I have another proxy and It is more necessary.This plug-in is less and less concise.
  • (2022-11-29) 未陈: 22-11-23 越来越不好用了,强制使用桌面吧。没必要吧,用户就是当作轻量的浏览器插件使用,这么迭代违反设计初衷。建议简单点,简单点。 22-11-29 This is very good. The web app modify API Response has been opened. For some users, only use to modify XHR/fetch request.
  • (2022-11-19) Amal S. Kuriakose: Damn, this is just one amazing extension! Been using it since a few weeks and I wanted to know if it was possible to redirect URLs and it can too!

  • (2022-11-02) Carl Hand: Requestly is awesome. I used to use Charles proxy in my day to day work but it always messed with my wifi. I haven't had any issues with Requestly. Requestly's UI is amazing too and great to work in

It also offering the session recording feature to easily track the steps and data for any bugs faced by someone. The sharing options of requestly rules helps to easily distribute the rules inside the team to setup easily and starts working. Thanks team Requestly!

  • (2022-09-22) Rob Simpson: Excellent product, and incredible support! As a marketing person, I'm pretty illiterate with code - my use case required some custom script, and Sachin jumped on it straight away. He was incredible helpful and a really nice guy at the same time. Thanks again - wishing you huge success with Requestly!
  • (2022-09-20) Anwesha Palit: I faced an issue with while redirecting to Safari with Requestly. Sachin and Sahil were prompt in their support and helped us out quickly and efficiently. Very much appreciated.
  • (2022-09-20) Yehuda Rokach: Requestly is so smart and easy to use. I use it while developing for lots of cases. The replace string and mocks are so powerful and easy to use, and the UI is so simple and easy to understand.

  • (2022-09-13) Simon Cohen: Great product!
  • (2022-09-08) Ankush Kumar: Great Product! Easy to use and very helpful for network analysis.
  • (2022-09-07) Eric Benson: First, Let me say. The support for this is simply amazing. They went way above and beyond the call of duty. Ok, let me explain. I run a small private school for a therapeutic boarding school in Texas called Resolution Ranch Academy. I have an unlimited number of Microsoft 365 Accounts. Unfortunately, I could not hand these out to my students due to a huge security risk. I had no way to keep the students from logging on to Microsoft 365 accounts that do not belong to our school. According to Microsoft support the solution was to use a proxy server that can insert and verify a code into the login traffic. Not, sure I explained that right, ( https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/tenant-restrictions ) Anyway, I had been sitting on this for a really long time trying to find a solution. One problem I had was using a proxy server in line with the security server we already had screwed up the ability to identify individual students on the network. Here is were Requestly came it. Requestly can preform this action as a browser extension right from Chrome! Alright, Now for the cool part. Friday night I installed the extension and was trying to work through the instructions. Call me ignorant, but I didn't fully understand what I was doing. So, I sent a message through the built-in support chat on the app. I got a response within seconds!!! Not only that, but the support guy, Sachin actually looked at the instructions for me and tent me a template to my Requestly extension. All I had to do was save it to my app and enter the Tenant ID from our Microsoft Azure account! Honestly, I have been sweating this for over a year. I cannot tell you what a hugh deal this is for us. I know this was not the intended use care for Requestly, but it worked beautifully.
  • (2022-09-07) Jeremy Evans: Really useful extension - we use it anytime we need to test something with a mix of local/staging/prod environments. It's very easy to reroute requests anywhere you like. Thoroughly recommend!
  • (2022-09-01) Jared Smith: Requestly is a must-have extension for anyone that works on front-end web. Requestly has totally replaced Charles Proxy, Fiddler, etc. for me due to the ease of use & better interface. 10/10 would recommend!

  • (2019-10-10, v:19.9.19) Stefano Capuzzimato: Modify query parameter rule not working correctly
    I have a rule set using your tool that would allow me to change a parameter usually included in the request. The rule is structured as follows: # Request URL contains - maxResults # add/replace param - maxResults # value - 20 Original URL: * http://localhost:8080/rest/api/2/search?jql=(project%20=%20%22MetroSystems%20automation%20test%22)%20and%20key%20!=%20MAT-15&maxResults=10&_=1570634038378 * http://localhost:8080/rest/api/2/search?jql=(project%20&maxResults=20&_=1570634067336 Long story short, it looks to me like we're losing a much bigger chunk of the original URL while we (correctly, at least) fix the parameter that we wanted to amend, and the resulting API request obviously dies screaming as the value of the parameter is no longer valid (missing round brackets and everything past the '=' sign). A way forward to amend the requests on the fly using your tool would be great. Please advise. Many thanks, Stefano

    Installed on my FF browser (69.0, 64-bit on Ubuntu 18.04) and found that although the install seems to go flawlessly that it never installed the app icon. so the extension is "installed" but there's absolutely no way to interact with the rule editing. Put Chromium on my system and the install and app icon worked perfectly so there must be something missing in the FF install process that's missing the app icon registration with the browser.
