Where Open Source Ends, HeroDevs Begins
At HeroDevs, we believe the web should be secure, stable, and sustainable for everyone—not just those on the latest version. We're a team of open source defenders on a mission to protect critical infrastructure from abandonment.
As open source software reaches end-of-life, businesses are left vulnerable without patches, compliance, or a plan. That’s where we come in. HeroDevs delivers commercial-grade, Never-Ending Support (NES) for deprecated and end-of-life frameworks, so you can run your legacy systems securely while planning upgrades on your timeline.
We’re building a safer, more sustainable web—one legacy framework at a time.
Giving Back to Open Source
We don’t just protect open source—we power it. HeroDevs contributes upstream patches, funds sustainability initiatives, and supports the communities behind the software we defend.
We’re proud to:
Sponsor long-term maintainers of major frameworks
Patch CVEs for abandoned open source projects
Lead funding efforts like the $20M Open Source Sustainability Fund
