Flags.md

Teams define flags in structured YAML or Markdown frontmatter blocks, commit changes through their normal code review process, and sync state to the FlagsMD runtime without separate tooling.

The platform supports gradual rollout configurations including percentage-based targeting, user segment rules, and environment-specific overrides. Its server-side evaluation engine handles flag resolution at low latency, ensuring that flag checks in application code add minimal overhead even at high request volumes.

SDK clients are available for Node, Python, Go, Ruby, and major frontend frameworks.

FlagsMD appeals to engineering teams that want the operational benefits of feature flags without adopting another SaaS dependency whose state lives outside their repository.

By treating flag definitions as code, teams gain the same review, rollback, and history capabilities for flag changes that they already apply to application logic, reducing the risk of poorly coordinated flag cleanup and flag debt accumulation.
