HTTP Toolkit Screenshot

HTTP Toolkit is a powerful tool that facilitates the analysis, debugging, and modification of HTTP(S) traffic. The free version offers essential features to capture, inspect, and manipulate HTTP(S) requests and responses seamlessly. It provides a user-friendly interface and requires zero setup, making it accessible to both beginners and experienced developers...

HTTP Toolkit Features:

Automatic setup for targeted interception of HTTP & HTTPS from various clients and platforms.

Supports desktop browsers (Chrome, Edge, Brave, Firefox), Android applications and browsers, backend & scripting languages (Node.js, Python, Java, Ruby), Docker containers, CLI tools, Electron-based applications, and more.

Acts as an HTTP(S) proxy for platforms without automatic setup, compatible with HTTP requests from any language or tool.


Allows exploration, search, and examination of HTTP traffic.

Offers skimming through traffic with highlighting by content type, status, and source.

Powerful filtering tools to precisely match and analyze relevant messages.

Provides detailed views of request and response attributes such as URL, status, headers, and body.

Inline explanations and documentation from MDN for better understanding.

Supports message body highlighting, autoformatting for various data types (JSON, HTML, JS, hex), leveraging the Monaco editor from Visual Studio Code.


Enables pausing and editing of live HTTP traffic.

Allows precise matching of requests and real-time editing of URL, method, headers, or body.

Manual response capability, responding directly to requests as they arrive and editing the real response on the way back.

Facilitates stepping through HTTP traffic request by request and manual mocking of endpoints and errors.


Supports fully automated mock responses with the PRO version.

Creation of rules to match requests and respond with customized content for quick prototyping against new endpoints or services.

Defines new endpoints, overrides existing ones, or replaces external services to reproduce tricky edge cases and test error handling.

Import and export mock rulesets to build complex setups and share them with the team.


Allows users to rewrite various aspects of requests.

Injects request timeouts, simulates connection failures, and redirects requests from one server to another.

Precise matching for targeting specific requests based on criteria.

Functions as a proxy or mock server depending on the requirements.

Pros of using HTTP Toolkit:
