In Where to learn how to build an A/B testing tool?For Ruby on Rails there is: https://github.com/flippercloud/flipper
In Ask HN: How did you build feature flags?Shameless plug (it's my project!), but there's also Flagsmith - https://github.com/Flagsmith/flagsmith
For completeness, the other OS projects I know of are:

In Flags vs. GatesHow does this compare to something like Flipper?

In Launch HN: Airship (YC W18) – Controlled rollouts of new featuresThere's a bunch of feature toggles libraries out there for pretty much every web language you can think of. Doing it statically is pretty easy, you can rewrite a similar library in a day or two. One Ruby[0] and Python[1] example below, but there are tons.
What you don't get out of those libraries alone is a couple things. One is a metrics pipeline if you want to actually A/B test and gather metrics on the success of different features. That's a hard problem because A/B metrics collection pipelines are something pretty much something everybody reinvents from scratch right now to fit their combination of language/logging tool/cloud host/data warehouse/BI tools/whatever.
The other big one is the managed configuration deployment - a UI that you can toggle features on and translate those to appropriately flipped toggles in all of your clients
Read the rest
(mobile, web backend, web frontend, whatever). That's a pretty big task to do and requires a hosted service one way or another. Flipper (below) looks like it integrates into a rails service and so has a UI, which is kinda neat (first time I've noticed an OSS solution that does that part - looks like theres a number of options that do this now), but you'd still need to reinvent tooling for mobile apps and such with it.
