Helicone is committed to being an open-source project. We believe in the power of open source for several key reasons:
  1. Transparency: We want our users to understand exactly how our software works and be able to trust it fully.
  2. Giving Back: We’ve benefited immensely from the open-source community, and this is our way of contributing back.
  3. Ease of Self-Hosting and Contribution: Open source makes it simpler for users to self-host Helicone and for developers to contribute to its improvement.
  4. Preventing Vendor Lock-In: We believe users should have the freedom to modify and control the software they rely on.
  5. Execution as the True Differentiator: We’re confident that our value lies not just in our code, but in how we execute and support our product.
