The bottom line
LaunchDarkly is an excellent feature management platform built for engineering teams. Its strength is progressive feature rollouts, kill switches, and server-side feature flags — capabilities that go well beyond A/B testing.
LaunchDarkly's experimentation works differently from traditional A/B testing: it's code-based, not visual. There's no visual editor, no split URL testing, and no revenue tracking. It's designed for product engineers testing feature variations, not marketers optimizing landing pages.
If you need feature flags or are an engineering team managing releases, LaunchDarkly is the right tool. If you need to visually test page variants, track revenue impact, and run experiments without code changes, Otter A/B is built for that.
