Signal lets your team ship code and release features independently. Toggle, target, and roll back in seconds — no redeployment, no drama, no code freeze.
No spam. One email when we open.
The reality
Shipping code has always been a bet. Signal removes the house edge.
of incidents are caused by a new deployment
slower to ship when every deploy is a risk
rollback time with a feature flag in place
The solution
Three primitives, zero friction. Feature flags that work exactly the way your team expects.
No redeployment
Your code ships. You decide when users see it. Enable, disable, and roll back in one click — without touching git.
Right audience
Target by user ID, email, country, or any custom attribute. Gradual rollouts from 1% to everyone.
Always in sync
Real-time WebSocket push keeps every SDK instance in sync in under 50ms. SSE and polling transports are also available — all three deliver the same payload so you can switch without changing a line of code.
How it works
npm install @code-signal/signalconst { enabled } = useFlag('new-checkout')// toggle from the dashboard, not from git"The fastest way to kill a release is to make it irreversible."
