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.
OpenFeature and Flipt are closely matched on ownership (97 vs 93) — this one comes down to pricing and to which trade-offs below you can live with.
OpenFeature
Not a platform — the standard that makes the platform swappable.
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.
Flipt
Flags defined in Git, evaluated by one Go binary.
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.
Side by side
6 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

Weighing both against staying on LaunchDarkly? Is LaunchDarkly free? What it actually costs →
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
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose OpenFeature
if a lower exit cost matters more to you than any single feature, and removes SDK lock-in entirely — swap providers in one line.
Choose Flipt
if flag definitions live in Git — reviewed, versioned and audited like code.
Neither, yet
if both carry a real cost you should weigh first — not a flag platform — you still need something behind it, and smallest project here — a real bus-factor consideration. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
OpenFeature vs Flipt — common questions
Is OpenFeature a better fit than Flipt for feature flags & experimentation?
It depends on what you are optimising for, and the honest split is this: OpenFeature scores 97 to Flipt's 93 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Flipt earns its place on a different axis — flag definitions live in Git — reviewed, versioned and audited like code. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
OpenFeature keeps its data local or in open formats, so leaving is an export rather than a negotiation. Flipt is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host OpenFeature or Flipt?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are OpenFeature and Flipt both alternatives to LaunchDarkly?
Yes — both appear in our LaunchDarkly comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off LaunchDarkly and now choosing between the two replacements, which is a narrower and much easier question.
