...because who says I can't write yet another link checker?

This thing was created from Hello Rust Episode 10. It's a link checker that treats Github links specially by using a GITHUB_TOKEN to avoid getting blocked by the rate limiter.

The existing link checkers were not flexible enough for my use-case. lychee runs all requests fully asynchronously and has a low memory/CPU footprint.

This comparison is made on a best-effort basis. Please create a PR to fix outdated information.

• report output in HTML, SQL, CSV, XML, JSON, YAML... format
• report extended statistics: request latency
• recursion
• use colored output (https://crates.io/crates/colored)
• skip duplicate urls
• request throttling

• https://github.com/analysis-tools-dev/static-analysis (soon)
• https://github.com/mre/idiomatic-rust (soon)

cargo install lychee

Set an environment variable with your token like so GITHUB_TOKEN=xxxx.

Run it inside a repository with a README.md or specify a file with

lychee <yourfile>

Collecting other link checkers here to crush them in comparison. :P
