About Us
Open Source SEO Tools is a community driven list of tools and resources for developers.
Who runs this directory
Open Source SEO Tools is run by Michał Snieżyński, creator of Bisibility. The directory helps people find open-source software for SEO and promotes Bisibility.
Bisibility's featured placement
Bisibility belongs to the directory creator. Its promotion is labelled on the homepage, catalog and profile. Featured placement is not an independent ranking.
What we check
Profiles link to reviewed source code and licenses, list requirements and separate software licensing from hosting and provider costs. The initial entries were reviewed against documentation, not tested as complete deployments.
Comparisons
Alternative guides compare specific tasks. They do not establish complete feature or dataset parity with a commercial SEO suite.
GitHub stars
Counts are dated snapshots from GitHub's public API and link to each repository. They are not product review ratings.
Interface image credits
Project-provided images may show illustrative data or earlier releases. Lighthouse is a historical example report, not a benchmark performed by this directory.
