Flipt vs GrowthBook
Both are alternatives to LaunchDarkly. Here's how they stack up — verified facts, no spin.
Also searched as GrowthBook vs Flipt — same comparison, one verdict.
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.
GrowthBook
Flags plus a real statistics engine — the experimentation answer.
GrowthBook is the option to look at when the reason you want flags is experiments rather than toggles. It runs A/B tests against your existing data warehouse — Snowflake, BigQuery, Redshift, Postgres — so the analysis happens where your data already lives instead of in a second copy, and it offers Bayesian and frequentist statistics rather than one opinionated method. Around 8.1k stars. The licence needs stating precisely: the core is MIT, but three enterprise directories are carved out under a separate commercial licence, so it is MIT-with-exceptions rather than plain MIT.

| Sovereignty Score | 93 | 83 |
| Open source | Yes | Yes |
| Self-hostable | Yes | Yes |
| Local-first | Yes | Yes |

| Pricing | Free and open source. One binary on hardware you already have. | Self-hostable core free. Cloud and enterprise tiers are paid. |
Flipt edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
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
GrowthBook
Strengths
- +Genuine statistics engine — Bayesian and frequentist, not a toggle with a chart
- +Runs experiments against your existing warehouse, no data duplication
- +Warehouse-native means no second source of truth to reconcile
- +Self-hostable with a real free path
Trade-offs
- −Enterprise directories are carved out of the MIT licence
- −Heavier to set up than the pure flag tools — you need a warehouse
- −Flag management is less polished than Unleash's
- −Overkill if you only want to turn features on and off
