A new web-based URL parser testing tool allows developers to compare how different programming language parsers interpret URLs, highlighting inconsistencies across implementations. The tool uses WebAssembly and Web Workers to support multiple languages, though it may have stability issues on Safari. It includes interesting edge cases where parsers commonly diverge, such as IDNA encoding and Windows file paths.
Background
URL parsing inconsistencies across different programming languages and libraries have long been a challenge for web developers, leading to potential security vulnerabilities and compatibility issues. This tool helps identify and understand these differences.
