Why open source
Transparency, security, and community-driven development aren't marketing words—they're why Reloop is open source from day one.
The open source advantage
Six reasons
that matter.
Open source isn't just a license—it's how we build trust with developers who depend on email infrastructure every day.
Complete transparency
Every line of code is visible. You know exactly how email is routed, stored, and delivered—no hidden algorithms.
No vendor lock-in
Use our hosted service, self-host on your servers, modify the code, or migrate whenever you want.
Security through visibility
Public code means more eyes on security. Issues get found and fixed in the open—not buried in a ticket queue.
Community innovation
Features and fixes from developers solving real problems. The roadmap is shaped by contributors, not a sales team.
Runs anywhere
Docker Compose, Kubernetes, or bare metal—or use Reloop hosted. Your infrastructure, your rules.
Accessible to everyone
Apache 2.0 with Reloop Labs use restrictions: free for personal and internal use, hosted or self-hosted.
The difference
Closed source asks you to trust.
Open source lets you verify.
