Elevenlabs OSS Engineers Fund: supporting the open-source projects that shape our work

Engineers Fund

Open source sits at the foundation of modern engineering. Many of the products we build at ElevenLabs depend on tools, libraries, and infrastructure created and maintained by people who often work without recognition or predictable support. Their work accelerates ours, and it expands what is possible for anyone building with audio and voice systems.

Today, we are launching the ElevenLabs Engineers OSS Fund, a program that directs sustained support to the open-source projects our engineers admire and rely on. Over the next six months, we are contributing $22,000 to projects and maintainers nominated by our engineering team. 

We will continue this program on a six-month cycle, with a new set of projects selected in May 2026.

Why we’re doing this

The pace of our work is possible in part because of the open-source ecosystem around us. It provides the compilers, runtimes, frameworks, editors, testing systems, and model tooling that support the backbone of our stack. Much of this infrastructure is maintained with limited resources. Supporting it directly is not only the right thing to do, it is also a practical investment in the stability and resilience of the systems we build on. The Engineers Fund is one way for us to contribute recurring and predictable funds to people who build software the world relies on.

How we select projects

Every six months, we ask engineers across the company to nominate the projects they depend on and describe how those tools support their work. We then assign funding across the nominated projects. This approach keeps the fund close to our actual workflows and ensures support flows to the projects that meaningfully improve our engineering, research, and product development.

This cycle includes a wide range of projects across audio, web infrastructure, testing, rendering, developer tooling, and core language ecosystems. A full list of supported projects and contribution amounts is included at the end of this post.

Total funding for the next six months: $22,000.

Looking ahead

The Engineers Fund is our commitment to providing stable, recurring support to the projects that make our work possible. We expect the next six-month cycle to include many of the same projects but also some new projects selected through the same engineer-driven process.

If you maintain an open-source project in audio, machine learning, distributed systems, or developer tooling, and our engineers rely on your work, there is a strong chance your project will appear in a future cycle.
