It would probably take some effort to hook it up to whatever billing platform you use, but it would make it easy to turn certain features on/off based on billing. Instead of checking if a customer has a specific plan, you instead have Unleash handle the features that are on/off and then check for those flags in the code.
Thanks for the link - am I getting it right that this is a Feature Flag system akin https://www.growthbook.io/ and PostHog Flags (also OSS)? At least I got this impression from their landing page.
It looks similar, but Unleash has a lot of really awesome features that let you configure rules for when flags are enabled/disabled. Stuff like turning them on for specific domains or customer or any other metadata you can feed into it.
I'm curious why one would want a "system" or a "library"?
I run a SaaS which has a feature system. Every plan has a set of features. There are additionally feature overrides for users. Checking if a feature is available to a user is a set membership query.
With a couple more lines of code I also generate my entire pricing (plan comparison) page, so that each plan shows all available features.
Not sure where a library would provide any value, there is barely any code for this (I mean, it's Clojure, so it's very succinct and expressive, but still).
