Pure open source, no caveats
No SSPL, no BSL, no exceptions. Tramline is open source, through and through, under the universally accepted Apache 2.0 License. Check out our source code, issue queue, or just run the system yourself, no strings attached. 

Why? We believe critical software should be open to public review and scrutiny. Modern release engineering practices are built on a backbone of open source software and we benefit from that too. Being open source guarantees the longevity of our product, and inspires confidence in our enterprise customers.
