Reviewer scorecard
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become essential.”
