REDBot

Business Profile

Core Value Proposition

REDBot provides lint for HTTP resources, testing protocol correctness, cacheability, content negotiation, and other HTTP semantics.

Target Customer

{"Web developers","Site operators / Webmasters","QA engineers","DevOps / SREs"}

Key Differentiator

Not a HTTP conformance tester; focuses on the HTTP semantic layer across headers and messages, reports problems, and is open-source under MIT with self-hosting options.

Implementation Timeline

Results are produced immediately after running a test; for ongoing monitoring and automation, you can deploy your own REDbot instance.

Pain Points

1Invalid syntax in headers
2Ill-formed messages (e.g., bad chunking, incorrect content-length)
3Missing headers

Key Features

1Checks HTTP resources for common problems and reports issues
2Assesses support for caching, content negotiation, Last-Modified and ETag validation, and partial content
3Allows adding custom request headers for tests
4Provides actionable guidance on how to fix issues
5Open source (MIT) with source code available; self-hosting option
