Sustainability Crisis: The Burning out of Open-Source Maintainers

21 September 2026

While open-source software powers everything from smartphones to supercomputers, the software behind the scenes is increasingly reliant on unpaid labor: 60% of maintainers are unpaid. According to a 2024 SonarSource survey, 60% have quit or considered quitting. These alarming figures suggest a sustainability crisis for open-source ecosystems - and the economy that relies on them.

Funding has not kept pace with the demands of maintaining the critical infrastructure that the software economy relies on. This resulted in burnout for 44% of open-source maintainers. Those who kept at it were not driven out by the difficulty of getting paid, or even by the unrewarding nature of the work, but by maintaining a double shift of full-time work and unpaid maintenance, hyper-responsibility and pressure to prove themselves.

These problems are tied to low reward, high demand, and hostile community dynamics. AI-generated code increases the review burden even as projects remain underfunded, and many maintainers work evenings and weekends.

It is important to recognize maintainer burnout as a sustainability problem for the software economy, not just a personal well-being issue. Sustainable software supply chains require sustainable maintainer incentives. The stakes are not just personal - they are economic.
