Open Source

Built in the Open

Our SDKs, tools, and integrations are open source. Contribute, customize, or just read the code.

Transparency Note

Our developer tools and SDKs are open source under MIT and Apache 2.0 licenses. The OmegaEngine platform (decision engine, audit infrastructure, cloud hosting) is a commercial service. This is the same model used by companies like Stripe, Twilio, and OpenAI.

Why Open Source?

Full Transparency

No Vendor Lock-in

SDKs work with our API, but the code is yours. Security teams can audit. Compliance teams can review. No black boxes.
