Very biased: I work for Eppo (after working for Split), and our solution works great. I don’t want to shill _too_ hard, but happy to answer any question. Another thing: Eppo is actually more focused on Experiment (A/B testing) analysis, and we let customers use any feature flag they want. Some clients use an in-house solution; some use Eppo, and many use commercial third-party options. If those systems have issues, our monitoring is often the first to flag it, and those errors are odd, so our clients pretty systematically flag us when that happens. That long explanation to say: I’ve seen a lot of how feature flagging system fail. Several a day, every day, for months. That’s why I can confidently say that Eppo is great, LaunchDarkly is great. Other commercial solutions… I have doubts: they work for basic use cases, but as soon as you have ad blockers, a bad connection, multiple ways to identify users (cookies vs. accounts; same account on mobile vs. desktop browser), or users who know how to edit their cookies, things get bad. In-house solutions (with one exception) also have common oversights. We talk a lot to experienced engineers who think they can build it —and they can, key patterns are simple— but tricky cases always pop up. I usually ask a few questions to clarify and help them understand what those gotchas are. Senior tech leads aren’t always… keen on thinking, “That’s too hard for me.” So if they push back even lightly, I tend to recommend people to go that way and expect them to come back weeks later, asking tough questions. It’s never lost time: they learn a lot about their own architecture, limits of spinning up new services, passing configuration, design, etc. More importantly, they learned that third parties have relevant experience building this.
