Introducing the Tidelift Subscription. Find out more on our blog.

The Tidelift Subscription

The software you already use. The professional assurances you need. Directly from the experts who know it best.



Open source you can depend on

In a recent survey, developers told us that almost 95% of their software applications include open source components. Every time a software developer incorporates another fantastic open source library or package into their application, it also introduces additional complexity.

The Tidelift Subscription brings order to this beautiful chaos, ensuring software development teams have open source software they can depend on.





Develop and deploy with confidence

The Tidelift Subscription delivers commercial-grade security updates, maintenance, and quality assurance for the open source projects you depend on, provided directly by the people who created them.



Key benefits

We’re creating a way to subscribe to open source software you can depend on—across every open source ecosystem. Several Tidelift subscriptions are already available, and we’re continuing to add coverage.
