Our open source licensing and ethos
The vast majority of the platform is open source. View our GitHub.
Most of the platform is under the BSD-3-Clause license. A small number of repositories are under the MIT license.
We built Flagsmith as an open source feature flag tool we needed and couldn't find on GitHub. Core functionality stays open, always.
Use cases for open source feature flags
Decouple deploy and release
Achieve continuous deployment by deploying behind flags, and then only toggling them on when a release is scheduled.
Using Flagsmith, you can release new features to a small percentage of your users initially, and then enable them for the rest of your users over time.
Once you’ve integrated the Flagsmith SDK and gated a feature with a flag, you can then easily use that flag to power A/B/n tests.
