The control plane for every feature
Ship features with confidence using boolean, string, number, JSON, and multi-variant flags. Every flag type supports the full targeting, scheduling, and lifecycle management capabilities.
- Boolean, string, number, JSON, and multi-variant A/B flags
- Sub-millisecond evaluation — no database calls on the hot path
- Percentage rollouts with consistent hashing (MurmurHash3)
- Instant kill switches and scheduled toggles
- Per-environment flag states with promotion between environments
- Prerequisites and mutual exclusion groups for complex release logic

Targeting Rule
Priority 1 · Enabled
Target the right users, every time
Precise user targeting with 13 operators and reusable segments. Build once, apply everywhere. Priority-based evaluation ensures consistent, predictable behavior.
- 13 targeting operators: eq, neq, contains, startsWith, endsWith, in, notIn, gt, gte, lt, lte, regex, exists
- Reusable segments for condition groups shared across flags
- Priority-based rule evaluation with fallback chains
- Custom attribute targeting for any user property
- Target inspector for real-time debugging of why a flag evaluated the way it did
Measure what moves your metrics
Run experiments directly on your feature flags — no separate tool required. Weighted variants with deterministic assignment ensure consistent user experiences across sessions.
- Weighted variants with deterministic assignment (MurmurHash3)
- Impression tracking for conversion measurement
- Per-environment experiment configuration — test in staging, run in production
- Built into every plan — not a paid add-on
- Combine with targeting rules for segmented experiments

chore: remove stale flags (3 files)
Stop flag rot before it starts
The AI Janitor autonomously scans your codebase for stale feature flags, categorizes them by risk, and opens cleanup pull requests — so your team can focus on shipping, not housekeeping.
- Autonomous stale flag detection across your entire codebase
- Category-aware staleness thresholds: Release (14d), Experiment (30d), Ops (90d)
- Auto-generates cleanup pull requests with context-aware diffs
- Supports GitHub, GitLab, Bitbucket, and Azure DevOps
- Configurable confidence scoring and compliance modes for regulated industries
- LLM-powered code analysis with provider flexibility
Switch without rewriting your codebase
Import your flags, environments, segments, and targeting rules from any major provider in minutes. Dry-run first to verify everything maps correctly. OpenFeature-native SDKs mean this is the last migration you'll ever need.
- One-click import from LaunchDarkly, ConfigCat, Flagsmith, and Unleash
- Dry-run preview before execution — see exactly what will be created
- Preserves targeting rules, segments, and per-environment configuration
- Operator and strategy mapping for each provider's unique semantics
- OpenFeature-native: switch providers without code changes
- Infrastructure as Code export: Terraform, YAML/JSON

Ship fast without compromising compliance
Enterprise-grade access control, audit logging, and change management built into every plan. Know who changed what, when, and why — with tamper-evident records you can trust.
- Four built-in roles: Owner, Admin, Developer, Viewer
- Per-environment permissions: can_toggle, can_edit_rules, can_manage
- Change approval workflows with configurable reviewers
- Tamper-evident audit logging with before/after diffs for every change
- SSO (SAML/OIDC), SCIM provisioning, and MFA enforcement
- IP allowlisting and custom roles (Enterprise plan)
Automate your release pipeline
Connect FeatureSignals to your existing toolchain with webhooks, scheduling, and infrastructure as code providers. Flags respond to your pipeline — not the other way around.
- Webhook notifications for flag lifecycle events: created, toggled, archived
- HMAC-SHA256 signature verification for secure payload delivery
- Flag scheduling: time-based enable/disable with timezone support
- CI/CD pipeline integration: flip flags from GitHub Actions, GitLab CI, Jenkins
- Infrastructure as Code: Terraform, Pulumi, Ansible providers
- Relay proxy for edge-cached evaluation with local sub-100µs latency
