Announcing HTTP View: one-click debugging for HTTP(S)

HTTP View is a beautiful, free & open-source HTTP inspector. This is the first release of HTTP Toolkit, and lets you intercept HTTP or HTTPS traffic with one click, explore & examine that traffic up close, and discover exactly what your code (or anybody else’s) is sending.

HTTP Toolkit is a project that I’ve been working on for a while, to build an open-source suite of tools for HTTP development. The goal is to intercept & examine HTTP, edit it live, analyse flows of HTTP requests to audit performance and security, and rapidly prototype HTTP clients or servers.

You might be familiar with Fiddler or Charles — this is a similar concept, but taken further, and updated to integrate closely with newer tools and technology.

This first release includes the core technology for this and the full set of working features for the read-only parts, with lots more to come soon. Some of the features included so far:

Capture HTTP & HTTPS with zero setup

HTTP View can do automatic hands-free interception for HTTP and HTTPS on a huge range of platforms, with more to come soon, from Chrome to iOS to Docker.

For any platforms without automatic integrations, it simply acts as an HTTP(S) proxy, so it’s compatible with almost all HTTP clients out of the box.

Quickly skim & search HTTP traffic

HTTP exchanges are automatically highlighted by content type, status and source, so you can skim through streams of requests, and easily spot issues. You can search over the full request & response URLs, statuses and headers too, to quickly find whichever message you’re hunting.

Deep dive into HTTP exchanges

If you pick a specific request, you can examine the full URL, status, headers and body up close to understand exactly what’s being sent.

You can also explore the details of request and response bodies, with built-in editor highlighting and autoformatting for JavaScript, JSON, all popular image formats, HTML, hex, etc etc.

All the body inspection is built using Monaco, the editor from Visual Studio Code, so it comes with all the power of VS Code built-in too.
