Best Postman Alternatives: Fastest API Testing Tools
For debugging, testing, and building APIs with HTTPs, you can effectively use HTTP Toolkit because it is built for this purpose. Also, this is the reason why it is known as a good Postman alternative for various purposes.
Comparing Charles Proxy, Fiddler, Wireshark, and Requestly
On the pricing front, Requestly strikes a balance between affordability and functionality. It is an open-source tool, offering freemium to individual developers and affordable pricing plans for team collaboration. We have also clearly differentiated how Requestly differs from Wireshark and other web debugging tools like Proxyman, Modheader, and HTTP ToolKit separately.

  • GrapheneOS โ€“ Break Free from Android and iOS
    I can add certificates on my unrooted android. That how HTTPToolkit [0] works, it only requires adb, which (thankfully) doesn't trip banking apps. Banking apps can (and do iirc) pin certificates, so a rooted phone adds no risk whatsoever. Also in my experience a rooted phone experience is by far more secure than the OEM androids. Security is supposed to assess risk objectively, yet "running on a Xiaomi phone with... - Source: Hacker News / 5 months ago
  • Charles Proxy
    For my rather simple needs I've been using https://httptoolkit.com free edition, I like that it launches a independent Firefox window on its own for the intercepting so I don't have to touch my working browser or deal with configuring a proxy anywhere. - Source: Hacker News / 7 months ago

  • APKLab: Android Reverse-Engineering Workbench for VS Code
    Https://httptoolkit.com also worth a look if you're interested in this space: has some neat automated setup for Android MITM that can be much simpler _and_ more effective than the manual config route (with automated Frida setup on rooted devices, so it handles unpinning too!). More UI & less CLI focused, so depends which way your preferences go there. - Source: Hacker News / about 1 year ago

  • How to Increase API Performance
    Caching helps minimize backend strain, reduce delays, and handle more requests, which translates to better scalability, smoother user interactions, and smarter resource use. Tools like Redis and Varnish have shown impressive results in high-demand API setups [1]. - Source: dev.to / over 1 year ago
  • API Caching: Techniques for Better Performance
    Varnish Cache โ€” A web application accelerator that serves as an intermediary between web clients and servers. It provides logging, request inspection, authentication and authorization, and throttling. Varnish can also enhance security as a web application firewall, hotlinking protector, and DDoS attack defense tool. - Source: dev.to / almost 2 years ago
  • Varnish Cache
    Varnish Cache is a tool that provides a caching HTTP reverse proxy in order to accelerate your web applications. Once Varnish Cache is installed in front of any server that understands HTTP and configured to cache the contents, delivery speeds are typically enhanced by a factor of 300-1000x, depending on architecture. Kilobyte22 finds this tool along with HAProxy to be a winning combo. Source: about 3 years ago
  • Leveraging Cache to improve Web Performance
    In this case, caching mechanism is situated in the proxy server or reverse proxy server like Nginx, Apache, or Varnish, and most probably it is a part of ISP (Internet Service Provider). - Source: dev.to / about 3 years ago
  • Beyond Changing Technology: Scaling Your Applications Efficiently
    To handle this level of traffic, you can use tools such as Varnish HTTP Cache, which caches the information of a news article starting from the first user who accesses and makes the request. Once Varnish caches the page, subsequent users will receive a response that is saved in memory. This process allows you to avoid unnecessary synchronous requests and send a quick response to users. - Source: dev.to / over 3 years ago
