About open source startups on Launchory

Open source startups are some of the fastest-growing companies in software, and this category collects the projects worth knowing: self-hostable alternatives to popular SaaS, developer infrastructure, headless CMSs and backends, automation platforms, and data tooling. Nearly all of them run a commercial open-source model — a permissive or source-available core you can self-host, plus a managed cloud tier that funds the work. That combination is why founders keep choosing them: you get an escape hatch from vendor lock-in, code you can audit, and usually a lower bill at small scale. When comparing open source startups, read the licence before the pricing page. AGPL, BSL, and Apache 2.0 imply very different things about what you can build on top and whether you can host it for customers.

Every listing in this category is screened before it goes live. Browse the full startup directory or submit your own open source product to get listed.
