Version: v2



  • Envio's licensing reflects open source ethos but is not OSI recognized.
  • Developers can use Envio's services without vendor lock-in, either by self-hosting or specifying an RPC URL.
  • The generated code is open and public
  • Our license allows self-hosting but restricts third-party competition with Envio's hosted service.
  • Envio may consider open-sourcing in the future but prioritizes stakeholder interests and market traction.

Our position

We're devs and we value OS ethos too, that's why our licensing mirrors a lot of the benefits from open source licensing however Envio and it's products do not use a recognized open source license by the OSI, we are however public and open and our licensing reflects this.

Our future business model lies in our hosted service and HyperSync requests and so we are protecting this, but to ensure continuity and no vendor lock-in, developers are able to run and develop on their indexer without either. Either by self-hosting, which our license permits or by specifying an RPC url in their indexer configuration and thus bypassing HyperSync.

Envio is in it's formative stages and though we may look to open source the software in the future we are dedicated to ensuring the best interests of all stakeholders. Going open source is some what of a one way function and it is easier to go open source than to proverbially go "closed source". Once we have gained more market traction we will review our position on going open source.
