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

    This one is truly a gem: https://httptoolkit.com It even bypasses SSL pinning on Android using 1 click. - 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

  • Best AI Monitoring Tools in 2026: LLM, Agent, and MCP Observability Compared
    Langfuse is the open-source standard for LLM observability. It traces every LLM interaction โ€” prompts, completions, latency, token usage, cost โ€” and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / about 1 month ago
