OpenFeature vs Flipt

Both are alternatives to LaunchDarkly. Here's how they stack up — verified facts, no spin.

Also searched as Flipt vs OpenFeature — same comparison, one verdict.

97

OpenFeature

Not a platform — the standard that makes the platform swappable.

OPEN SOURCEApache-2.0SELF-HOSTLOCAL-FIRST

OpenFeature is a CNCF specification and set of SDKs defining a vendor-neutral API for evaluating feature flags. You write against OpenFeature, then plug in a provider — LaunchDarkly, Unleash, Flagsmith, GrowthBook, or a local file — and changing vendors becomes changing one line at startup instead of touching every call site. It stores nothing and manages nothing, so it is not an alternative in the usual sense. It is listed here because it is the highest-leverage thing on this page: adopt it and the rest of this decision becomes cheap to change your mind about. Apache-2.0 under the CNCF.

93

Flipt

Flags defined in Git, evaluated by one Go binary.

OPEN SOURCEGPL-3.0SELF-HOSTLOCAL-FIRST

Flipt takes a GitOps approach: flag definitions live in your repository as files, get reviewed in pull requests like any other change, and are evaluated by a single Go binary that can run entirely offline with no external dependency. For a platform team that already runs everything through Git, this makes flags an ordinary part of the deployment pipeline rather than a separate control plane somebody has to remember to check. GPL-3.0 with about 4.9k stars. The trade is deliberate: no polished dashboard for product managers, because the source of truth is a file.

The verdict

OpenFeature edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.

OpenFeature

Strengths

  • +Removes SDK lock-in entirely — swap providers in one line
  • +CNCF-governed vendor-neutral standard with broad provider support
  • +LaunchDarkly itself ships a provider, so adopting it costs you nothing today
  • +Makes this whole comparison a reversible decision

Trade-offs

  • Not a flag platform — you still need something behind it
  • Thin abstraction: vendor-specific features may not be exposed
  • One more layer between your code and the evaluation
  • Provider maturity varies across the ecosystem

Flipt

Strengths

  • +Flag definitions live in Git — reviewed, versioned and audited like code
  • +Single Go binary, runs air-gapped with no external calls
  • +Fits a GitOps workflow with no extra machinery
  • +GPL-3.0 with no enterprise carve-out

Trade-offs

  • Smallest project here — a real bus-factor consideration
  • No dashboard a non-engineer will happily use
  • Git-based workflow means non-technical staff cannot flip a flag
  • No experimentation or statistics
