Bottom line
Unleash if you self-host; LaunchDarkly if you would rather not own it.
The short answer
Both flip feature flags, and both can take production down if the agent guesses wrong. LaunchDarkly is the managed product with the broader targeting engine and the bill to match; Unleash is open source and self-hostable, which matters if flag state is something your security team wants on your own infrastructure.
