Features
What featflags includes
Approvals, scheduled changes, release templates that advance on their own, guarded releases, kill-switch URLs and webhooks are on the Team and Business plans, and bandits and single sign-on on Business. The rest is on every plan, with one experiment at a time on Free.
- LaunchDarkly-style targeting
- Contexts with kinds and multi-contexts, individual targets, prerequisites, segments, and regex, semver and date operators.
- An importer that keeps buckets
- Flags imported from LaunchDarkly keep every user in their variant, and --verify compares evaluations with LaunchDarkly’s own SDK.
- Large customer lists
- Target an uploaded list of customer IDs, up to 10 million keys on Business. Private lists need a token your server issues.
- 14 SDKs, the same answers
- TypeScript, React, React Native, Go, Python, Java, Rust, .NET, Ruby, PHP, Elixir, iOS, Android and Flutter give the same answer for the same user.
- OpenFeature and OpenTelemetry
- Providers for Go, Python, Java, .NET, Ruby, PHP, Elixir, iOS, Android and Flutter, hooks in every SDK, and spans that follow the semantic conventions in all but Flutter.
- Experiments and bandits
- A/B tests on any flag with Bayesian or frequentist results you can read at any time, guardrail metrics and a check for uneven splits. Experiment data uses IDs only you can link back to a person.
- Change control
- History with diffs and restore, required comments, approvals, scheduled changes, time-based ramps and release templates reused across flags.
- Guarded releases
- A release template can watch guardrail metrics while each step is live and pause, or go back a step, when the new variant does worse than the old one.
- Operations
- Terraform provider, CLI, webhooks and Slack, kill-switch URLs, SDK key rotation, roles and scoped tokens.
- Single sign-on
- SAML or OpenID Connect through your own identity provider, for the email domains you verify. People join on their first sign-in, and you can require it for everyone but owners.
- AI assistants
- A hosted MCP server: Claude, Cursor or another assistant acts as you, and its changes go through the same comments and approvals.
- Analytics without personal data
- Counts per variant, with a warning when a split looks uneven. Exposure events go to your own code if you want them.
When to pick something else
Where featflags falls short
You need changes everywhere in under a second
Servers get a change within about 5 seconds and browsers within a minute. Several tools here push changes in real time, some only on enterprise plans.
You need an experimentation platform
We run A/B tests and bandits with Bayesian or frequentist results, but have no CUPED, holdouts or mutually exclusive experiments, don’t break results down by user attribute and don’t analyse data in your own warehouse. LaunchDarkly, Statsig and GrowthBook offer CUPED, holdouts and warehouse analysis, some of it only on paid plans.
You need SCIM or single sign-on on a smaller plan
Single sign-on is on Business, and people join on their first sign-in: there’s no SCIM to add or remove them from your identity provider. ConfigCat has SAML and SCIM on every plan.
You need self-hosting or an SDK we don’t have
featflags runs as a hosted service only, and has no SDK yet for C++ or for game engines such as Unity and Unreal Engine.
Try it with your own flags
Import from LaunchDarkly or start from scratch. The Free plan doesn’t need a card.
