Feature Flags

Built OpenFeature-native from day one specifically so you're not stuck with them if you change your mind later.

Other products from Feature Flags

The category-defining flag platform — mature and powerful, but you'll feel the enterprise pricing before you feel the need for it.

Flags and real experiment statistics in one dashboard, which is why OpenAI and Notion run releases through it instead of a spreadsheet.

Open source flags you can self-host for free and actually own, instead of trusting a vendor's uptime page.

The biggest open source flagging project by a wide margin — pay for managed hosting or run it yourself for nothing.
