Tidelift joins Sonar

We’re excited to share that Tidelift has signed a definitive agreement to be acquired by Sonar, the leading provider of code quality and security solutions. Read the full press release.

For Tidelift and Sonar customers, this will be a powerful combination. Both Tidelift and Sonar have deep open source roots, a developer-first focus, and a shared interest in proactively improving the quality and security of code.

Sonar’s code quality and security solutions are used by over 7 million developers and 400,000 organizations worldwide, including the DoD, Microsoft, NASA, MasterCard, Siemens, and T-Mobile. These solutions help developers prevent code quality and security issues from ever reaching production, resulting in more secure, reliable, and maintainable software.

Tidelift helps organizations improve the health and security of the open source powering their applications and is the only source for human-validated data about the secure development practices followed by the world’s most critical open source projects.

With the addition of capabilities from Tidelift, Sonar will be able to help its customers analyze, improve, and secure all code, including code written by developers, AI-generated code, and open source libraries.

Tidelift customers and maintainer partners will not experience any disruption to their current experience, and we’ll have more details to share in early 2025 as Tidelift is fully integrated into Sonar.

Almost eight years ago, when Jeremy, Havoc, Luis, and I founded Tidelift, we did so to pursue the mission of making open source work better—for everyone. In my conversations with the leadership team at Sonar, it has become clear to me that Sonar will provide a tremendous platform for us to scale what we’ve built together to the next level and continue to fulfill that original mission.

I’d like to take a moment to say thank you to all of the employees, customers, partnered maintainers, and other friends who have helped Tidelift grow over the past eight years. We appreciate your support, and look forward to an even more promising future as part of Sonar!
