Feature Management

Feature flags that obey the contract.

OpenFeature-compatible feature management with entitlement-driven evaluation, CEL targeting, and built-in adoption analytics. Your flags know what the customer paid for.

Feature flags were never meant to live alone.

Traditional tools treat flags as isolated switches. But in B2B SaaS, a flag's value depends on who is evaluating it: Does this customer have the right license? Are they in the right deployment zone? Have they exceeded their quota?

Traditional approach:

[LaunchDarkly] ←── custom sync ──→ [Stripe] ←── custom sync ──→ [Your Code]

Kaiten approach:

[Kaiten] ← one source of truth → [Your Code]

"Is flag on AND does the contract allow it?" — answered in one call

Everything your flag tool should have been.

OpenFeature Native (OFREP)

Zero vendor lock-in. Day one.

Kaiten implements the OpenFeature Remote Evaluation Protocol. Use the standard OpenFeature SDK in your language of choice. If you ever want to switch providers, you change one line of configuration.

Entitlement-Driven Evaluation

Flags that respect the business.

Unlike standalone flag tools, Kaiten flags are dynamically computed against the customer's active license. If the contract doesn't include a feature, the flag is forced to Off — regardless of targeting rules.

CEL-Based Targeting

Surgical targeting with real expressions.

Target feature flags using the Common Expression Language (CEL) — the same expression engine used by Google Cloud IAM and Kubernetes. Write real logic, not UI-click conditions.

Progressive Rollouts

Ship with confidence.

Roll out features gradually using percentage rollout, CEL targeting rules, date-based schedules, or instant kill switches. Combine multiple strategies. Support variants with typed payloads.

Built-in Adoption Analytics

Know what's used. Without a single tracking event.

Every flag evaluation is natively recorded. Feature adoption rates per customer, evaluation frequency over time, accepted vs. rejected evaluations — all out of the box.

Why not just use LaunchDarkly?

LaunchDarkly, Flagsmith, and Unleash are excellent feature flag tools. But they only solve one-third of the problem.
