Ada.Url brings the Ada URL parser to .NET: 1.9x faster than System.Uri, WHATWG-compliant
lemire · x · 2026-09-19
Ada.Url brings Ada — the C++ URL parser behind Node.js, Cloudflare Workers, and Datadog — to .NET. It's about 1.9x faster than System.Uri on Linux x64 (1.4x on macOS arm64, parity on Windows), allocates zero bytes on the UTF-8 path (vs 370 bytes per URL), and is WHATWG-compliant, unlike System.Uri. Open source on GitHub.
