Feature flag tools

Feature flag tools that live in your stack

Everything you need to ship behind flags: rollouts, targeting, kill switches, experiments and governance, evaluated locally in your SDKs and managed from one console. No per-seat meter deciding who gets an account.

No card required

01 · Release control

Ship on your schedule, release on the flag's

Boolean + multivariate flags

On/off toggles for releases, string and number variants for experiments and config. Unlimited flags on every plan, named and searchable like code.

Percentage rollouts

Walk a flag from 1% to 100% with one slider. Consistent hashing keeps users in stable cohorts across every SDK and service, so a gradual rollout never flickers.

Targeting rules

First-match rules on any attribute you pass: user id, plan, country, device, or your own. Internal first, beta next, everyone last.

Kill switch

One click turns a misbehaving feature off for every user in about 3 seconds, while your deploy stays put. The pager stops; the redeploy never starts.

Scheduled + progressive rollouts

Schedule a step-up ladder in advance, or let guardrail metrics advance the rollout automatically on Scale plans.

Environments

Dev, staging and production copies of every flag, promoted intentionally. Two environments on Launch, unlimited from Team up.

02 · Experimentation

Measurement built into the same flags

A/B and multivariate tests

Any flag becomes an experiment: assign variants with the same consistent hashing, attach a metric, read the result in the console.

Guardrail metrics

Error rate, latency and your own counter-metrics watch every rollout, so a conversion win cannot hide a reliability loss.

Sequential analysis

Scale plans add sequential testing so you can peek at results without inflating false positives.

Full details on the A/B testing software page.

03 · SDKs and performance

In your stack, out of your request path

SDKs stream your ruleset and evaluate flags in-process: sub-millisecond checks, no network hop per decision, and fail-safe behaviour if anything upstream is unreachable. Flags serve their last-known value, then your coded default. Your app never waits on us.

React Next.js Node.js Python Go Java Rails iOS Android

Linked SDKs have setup guides; the rest ship with the same core API. All SDKs are part of the early-access program.

One call, every stack < 1 ms

// Node.js
await flags.isEnabled('checkout.new-flow', ctx)

# Python
flags.is_enabled("checkout.new-flow", **ctx)

// React
useFlag('checkout.new-flow', false)

04 · Governance and safety

Controls your security review will ask about

Audit log

Every flag change records who, what, when and the previous state. Retention controls on Enterprise.

Roles and RBAC

Separate who can edit rules from who can flip production flags. Advanced RBAC on Scale and Enterprise.

SSO / SAML / SCIM

SSO on Scale; SAML and SCIM provisioning on Enterprise, so access follows your directory.

Compliance posture

SOC 2 is planned and in progress, stated honestly. DPA and invoicing available on Enterprise.
