Founder of @coollabsio. I build self-hostable alternatives to closed SaaS: tools you actually own.
I built a 5-person business from these free and open source apps unintentionally, lol.
- Software should be free and accessible to everyone.
- 100% open source. No features locked behind paywalls. No enterprise edition.
- Forever free. Not a growth hack - a core belief that will not change.
