# Polylane for release management

> Deployment monitoring with automatic rollback: every deploy watched against baseline, regressions tied to the change behind them, rollbacks you opt into.

Ten deploys a day. One of them is bad. Polylane finds it and rolls it back. Every deploy is watched out of the box, regressions are tied to the change behind them, and where you allow it, the bad one is rolled back on its own.

- Every deploy watched against how the service normally behaves
- Regressions tied to the exact change behind them
- Opt-in rollbacks: three per hour, receipted, on the record

## How it plays out

### Every deploy is watched, out of the box. What changed, who changed it, and the signals most likely to break.

No setup, no alert rules: every deploy and config change becomes a change record with an impact level, and the signals most likely to break get watched against their baseline at the change.

### Rollback, if you want it. You say when, in plain English: an agent handles the rest.

Rollback is the one decision left. Say when it's allowed; if error rates or p95 latency regress against baseline after a deploy, the agent restores the previous version and says why.

### Roll back now. Fix properly after. The rollback buys time: the real fix follows for your review.

Rollbacks run on Cloudflare, Vercel, Render, and Fly.io: three successful per hour per target, blocked when parallel passes disagree, every one on the record. The permanent fix follows with the evidence attached.

## How Polylane works

- **It learns your system first.** The context graph maps every resource and dependency across your clouds, repos, and observability providers. Agents reason over real topology, not guesses.
- **Detection without thresholds.** Built-in checks for every provider, plus checks generated from your own saved queries and dashboards. A statistical pass and an agent decide together, and an improvement never raises an issue.
- **Investigations that show receipts.** Every claim links back to the query, log line, or change record behind it. A verdict without evidence falls back to inconclusive.
- **Writes are earned, never assumed.** Accounts connect read-only. Rollbacks are off by default, rate-limited, and on the record. Code changes go through your normal review.
- **It gets sharper every week.** Memories, daily notes, and monitoring queries re-confirmed against real data: July's investigation learns from June's.

## Questions

### Which platforms can Polylane roll back?

Cloudflare, Vercel, Render, and Fly.io deployments, restoring the last known-good deploy. Rollbacks are off by default: you enable them per automation and can turn them off at any time.

### What stops an automatic rollback loop?

Hard limits in the platform, not agent judgement. Three successful rollbacks per hour per target, one rollback in flight at a time, and when parallel passes disagree on the version to restore, the action is blocked and escalated to you.

### Does it need my CI pipeline?

No. Polylane reads deploys from the providers themselves. The pull request review runs as a GitHub check you can require, but nothing about your pipeline changes.

### What about changes that aren't deploys?

Config edits, scaling events, and security changes are recorded and watched the same way. When a queue misbehaves twelve minutes after someone lowered its visibility timeout, the investigation starts from that change.

### Can I see why a rollback happened?

Every rollback is receipted: the automation run, the signals that regressed, the version restored, and the reasoning land in the record, and results are delivered to Slack, email, or a webhook.
