Feature Flags / Remote Config
flagd is free and open source while Convert runs on paid subscription pricing. Convert: A/B testing and personalization platform with no-cookie tracking and privacy-first architecture. Flagd: Feature flag daemon with a Unix philosophy. Reference OpenFeature-compliant backend supporting HTTP/gRPC evaluation, targeting rules and OpenTelemetry tracing. Convert fits gradual rollouts to reduce risk. Flagd fits platform teams standardizing on OpenFeature with self-hosting. On our rubric Convert scores 3/5 for developer experience and 4/5 for transparency, while flagd scores 5/5 and 5/5. The honest trade-off: Convert's main drawback — Solo developer shipping to production; flagd's — Minimal UI; configuration is file-driven. For flagd: Reference OpenFeature backend with clean Unix design. Convert is explicitly not the right pick for solo projects. Flagd is not aimed at teams that need a polished no-code flag dashboard. Another Convert advantage: Kill switches for features. Another flagd advantage: HTTP and gRPC evaluation, flexible targeting. Another Convert friction point: Products with no users yet. Another flagd friction point: Not a product; you build dashboards yourself.
Quick take
Convert is for gradual rollouts to reduce risk; flagd is for platform teams standardizing on OpenFeature with self-hosting; decide on pricing model.

Choose Convert if gradual rollouts to reduce risk, and if you'd rather pay for a managed service than run infrastructure yourself.
Not for: Solo projects
Choose flagd if platform teams standardizing on OpenFeature with self-hosting, and if you want to avoid recurring license costs and are willing to self-host.
Not for: Teams that need a polished no-code flag dashboard

No: flagd is free and open source, while Convert runs on paid subscription pricing. Convert may still be cheaper in total cost once you factor in hosting, maintenance, and engineering time to run flagd yourself.
Moving to flagd is reasonable on its side — it's low lock-in (OpenFeature OSS daemon, portable). The friction is on the way out of Convert, which is medium lock-in (A/B test data exportable). Budget time for data export and integration rework.
flagd scores higher in our rubric (5/5 vs 3/5 for Convert). Transparency is 5/5 for flagd and 4/5 for Convert. DX scores are rubric-based, not benchmarks, so evaluate against your own toolchain.
They sit in the same category, so yes — flagd is a plausible alternative for many Convert use cases. It fits best when platform teams standardizing on OpenFeature with self-hosting. Skip it if teams that need a polished no-code flag dashboard.
