Dev open-sources OpenSEO, an Ahrefs alternative for teams done paying $129/month

A developer named Ben built OpenSEO, an open-source rival to Ahrefs ($129/mo) and Semrush ($139.95/mo). The reviewer's takeaway after an hour: it does very little, deliberately—no 40 menus, no upsell popups. You type a topic to see search volume and ranking difficulty, drop in a competitor's site to see the keywords bringing them traffic, pull their backlink sources, and run a crawl-based site checkup. There's no subscription: connect a data account and pay per search, or self-host to skip the fee entirely. The repo has 20k GitHub stars, a sign of how many small businesses were done paying rent.
