Loved by engineers and product teams
Flagmint's SDK is the cleanest I've used. We went from zero to production feature flags in under an hour.
The TypeScript support is phenomenal. Autocomplete for flag names and values has saved us from countless bugs.
Finally, a feature flag tool that doesn't slow down our builds. Edge evaluation is a game-changer.
