Open Source Startups

About

Open Source Startups is a directory of open source projects and self-hostable alternatives to popular tools such as Notion, Slack, Zapier and Airtable. It lists 856 projects across 12 categories and ranks them by GitHub stars. To submit, a founder pastes a GitHub repository URL, and the site pulls stars, language, license and topics automatically. The submission form also asks for a project name, tagline, category, website and the submitter's name and email. The pages reviewed do not state whether listing is free, whether an account is required, how long review takes, or what type of link a listing receives. No paid listing tiers or advertising placements appear on the pages reviewed. Founders should confirm these terms with the site before submitting.
