LibHunt

LibHunt helps developers compare programming libraries and tools, organised by language and topic with alternatives pages that rank well for library comparisons.

Suggesting a repository or product is free with an account and goes through editorial review; members can vote. Link type is unconfirmed.

Estimated traffic is around 400K monthly visits — substantial for a developer-focused site. Strongest fit for open-source libraries and SDKs rather than commercial SaaS.
