Unleash does support open source and let us the chance to either use their cloud or use it on our self infrastructure

It is very simple to set up feature toggles through the UI. It guides you well along the process and it feels nice to use.

We looked at 10 feature management solutions and Unleash came out on top. Both the server and the SDKs are fully open-source. It has a modern architecture with server-side assignements in the SDK. The documentation is great too. For the managed solution: - Fair pricing model that is based on number of operators and not on traffic. - Role-based access, audit log and SSO. - Data privacy: user IDs are not tracked and service can be run in the EU. - Very responsive and reactive support. It was easy to integrate into our infrastruture. The grouping toggles into projects and creating API keys for sets of projects has enabled us to better separate permissions of our apps. We have a lot more stability with Unleash compared to our old system.
