Feature flags, A/B testing, and multi-armed bandit experimentation for engineering teams. Event-based pricing with no per-seat fees. Free tier available.
A startup from the United States that is founded by Robbie Crenshaw.
This page is designed to help you find out whether SignaKit is good and if it is the right choice for you.
SignaKit is a feature flags, A/B testing, and experimentation platform built for engineering teams who need full control over software releases without per-seat pricing or vendor lock-in.
At its core, SignaKit enables teams to wrap features in conditional checks controlled from a central dashboard — turning deployments into low-risk events. Flags are evaluated locally inside the application process using a cached configuration distributed through AWS CloudFront, producing sub-millisecond evaluation with no network roundtrip on the hot path. Bucketing is deterministic via MurmurHash3, so the same user always receives the same variant across sessions and devices.
SignaKit ships official open source SDKs, for Node.js, React, React native, Browser/vanilla JS, Swift, Flutter, Go, Java, Python, PHP, and Laravel. The Laravel SDK — with facade support and Artisan integration — is a notable differentiator; most managed feature flag platforms do not offer a native Laravel integration.
Pricing is event-based with no per-seat fees. The Free plan includes 1 million events per month, 3 team members, and 1 project with no credit card required. Paid plans (Starter at $39/month, Growth at $119/month) add higher event limits, more projects, more team members, and shorter experiment snapshot intervals. All plans include multi-armed bandit optimization.
Listed in
Feature flags
Boolean and multivariate flags with percentage rollouts, audience targeting by any user attribute, and instant kill switches for emergency rollbacks
A/B testing
Controlled experiments with statistical significance tracking, variant exposure logging, and result snapshots at configurable intervals (down to 1-hour cadence on Growth)
Multi-armed bandit
Bayesian adaptive experiments that automatically shift traffic toward the winning variant as results accumulate, included on all plans including Free
Audit history
Unlimited audit log of every flag change, who made it, and when
Slack notifications
Real-time alerts on flag changes and statistical significance milestones
Data Export API
Pull raw exposure and event data into your own warehouse (Growth and Enterprise plans)
SignaKit delivers ~0.2ms feature flag evaluation with built-in A/B testing and experimentation in a single SDK, with no bloated SDKs or per-seat pricing.
SignaKit is a fraction of the cost of LaunchDarkly or Statsig with usage-based pricing starting at $29/month — no enterprise contracts, no per-seat fees.
Software engineers and engineering teams at startups and growth-stage companies who want to ship faster with feature flags and experimentation without vendor lock-in.
SignaKit was founded in 2026 by Robbie Crenshaw, a software engineer frustrated by the complexity and cost of existing feature flag tools, to build the developer-first alternative.
SignaKit is built on Next.js, Node.js, PostgreSQL, and AWS, with SDKs available for 11 languages and frameworks including Node, React, Python, PHP, Flutter, Go, and Swift.
SignaKit launched in 2026 and is building its early customer base — reach out at hello@signakit.com if you'd like to be featured.
