SignaKit - Feature Flags & Experiments
Feature flags & A/B testing for engineering teams
SignaKit is a developer-first feature flag and experimentation platform. Ship faster with ~0.2ms flag evaluation, built-in A/B testing, and SDKs for 11 languages. Usage-based pricing from $39/month — no per-seat fees, no enterprise contracts.
I'm Robbie, founder of SignaKit. I built this after spending years on engineering teams that were either paying thousands a month for LaunchDarkly or duct-taping feature flags together with environment variables.
SignaKit gives you: - ~0.2ms flag evaluation (edge-ready, no latency cost) - Built-in A/B testing & experimentation with statistical significance alerts - SDKs for Node, React, React Native, Browser, Python, PHP, Laravel, Flutter, Go, Swift, and Java - Usage-based pricing — Starter is $39/month for 5M evaluations
It's the tool I always wished existed: powerful enough for serious experimentation, simple enough to set up in an afternoon, and priced for teams that aren't yet enterprise.
Free tier available. No credit card required to start.
Happy to answer any questions — I'll be here all day.
