From what I've heard here on HN, most of these tools are overpowered (and with prices to match) for the needs of non-enterprise apps.
I've started on a no-code page editor with a trivial A/B framework. Basically it's click your HTML element (any text or ) and modify it as you please. Then set a % chance the user will get the edited variant vs the original.
I'd like to eventually start selling this thing; and this is my attempt at "talk to your customers."
What is a low feature set tool I can build that brings outsized value for a much lower monthly price tag?
We always needed to be able to have different rollout percentages based on build version and environment: e.g release feature A to 10% for app version v1.2.34 on production, 100% on staging.
Another nice to have is have a feature enabled for all users who are logged in with email that end with @myexamplecompany.com.
Change history is convenient, e.g Tom changed the flag on Friday. Quite often, the UI need to be usable for both developers and non-devs (product owners, designers).
I used Firebase AB testing and Split.io for it.
Good luck, looking forward to seeing what you build.
