OpenFeature – open standard for feature flags

• go-flagz

  1 204 10.0 Go

  Dynamic flag management for Go.

This is a good start. Long road ahead on this. Some comments on the design:

1. If there were more similarities to how Prometheus defines flags I think that would be better. Adding metadata like help text and other things that prom has would be nice.

2. Having some method to identify what flags a binary thinks are set (and more specifically the set to non-default values) from a process running outside of the binary is extremely helpful. [0]

3. Defining schemes for flag rollouts. They should be able to be gradual, canary + gradual, global.

4. Some integration with common web/rpc frameworks that would allow you apply flags to a user population ("only the devs from our team should see this feature") is very helpful as well.

I believe the idea is that you run feature flag management as a separate service. It's not meant for desktop software but rather as a component of a microservices architecture. This is not uncommon - I know at least one of the FAANGs has something like this internally.

Flagsmith [1] (formerly Bullet Train) is another open source feature-flags-as-a-service software, and they have their own SaaS offering now.
