Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
