In general, I'd say most tech businesses are aware of Optimizely and the value proposition is quite compelling. I certainly wouldn't try to save money on our Optimizely spend by building any part of their system myself. But if I could save the company $700/month (the price for 50k MAU, which doesn't even cover our requirements) by implementing something as simple as feature flags, I'd add it to our development roadmap. For smaller companies, ~$10k a year is not trivial. However, I acknowledge that I may be vastly oversimplifying, and am not knowledgeable enough about LaunchDarkly to speak so brazenly about how I could do it myself. My main point is that as a small web development company, we have this feature in our builds already, and it only cost us a couple hours of development time to implement it.
