Stores feature flags directly in Git repositories with full version history and blame support, enabling seamless branching and deployment alongside code using existing CI/CD pipelines, as emphasized in the 'Git-Native by Design' section.

Runs as a single binary with no external database dependencies by default, offering zero-infrastructure setup and keeping data ownership within your infrastructure, highlighted in the 'Zero infrastructure' claim.

Uses Server-Sent Events (SSE) streaming API for instant flag propagation to client SDKs without polling, reducing latency and improving responsiveness, as noted in the 'Real-time updates' feature.

Supports environments mapped to Git branches, directories, or separate repositories for complete isolation, allowing flexible workflow integration across dev, staging, and production.
