StackCircuit365
npm
Prerelease 0.5.0 live // Sep 2, 2026

Every release has a safety circuit.

StackCircuit365 watches your GitHub to Vercel deployments. When a release breaks production, it works out which deploy caused it and brings back your last verified healthy version, but only within the rules you set. Free forever for developers.

Under the hood

For Developers

You know a deploy from a rollback. See exactly what runs, from webhook to verified recovery.

/ 01Recovery modes

You decide how much it is allowed to do.

Start in Observe Only and move up as you learn to trust it. Nothing touches production until your policy says it can.

Default

Observe Only

Detects incidents and writes an evidence report. It alerts you and changes nothing. This is where every account starts.

Recommended

Approval Required

Detects a likely regression and sends a rollback recommendation. You approve it in the dashboard, or later from Slack.

Opt in

Auto-Recover

Performs a rollback on its own, but only when every strict safety rule is met. Off until you turn it on, and only after real testing.

/ 02A worked incident

Watch a real regression get contained.

This is a simulated timeline of a bad deploy caught in Approval Required mode. Step through it to see what your team would receive.

    Production deployment promoted

    Vercel promoted dpl_7c33a to production and StackCircuit365 linked it to commit e9f14a2 "add pricing table query".

01 / 05
/ 03Scope

One narrow job, done properly.

What it is

  • A release-recovery tool for teams that ship often
  • Built for GitHub, Vercel, Next.js, and TypeScript
  • Made for one to twenty engineers with no dedicated SRE
  • Focused on the minutes right after a deploy

What it is not

  • Not a generic uptime monitor
  • Not a full observability platform
  • Not a replacement for Sentry or Datadog
  • Not an enterprise incident-management suite
  • Not an AI coding chatbot
/ 04Safety first

The AI never decides to change production.

A deterministic policy engine controls every rollback and every write. The AI reads evidence, connects a failure to a commit, and drafts the report a human reviews. It stops at the door of any database migration, auth change, billing path, secret, or anything it is not sure about.

StackCircuit365 must be safe before it is impressive. That rule comes before every feature on the roadmap.
