Auto-rollback Vercel production if Honeycomb error budget burns

What it does

This workflow guards the moments right after a production promotion. Once a new build goes live on Vercel, it queries Honeycomb for the freshly deployed version's error rate and p95 latency over a short bake window. If the new release is burning the error budget faster than your threshold, it rolls Vercel back to the last good deployment and escalates to on-call.

When to use it

Use it when a green CI gate is not enough and you need real production telemetry to confirm a release is healthy — catching regressions that only appear under live traffic.

How it works

  1. 1A Vercel production-deployment-succeeded webhook fires with the new deployment ID.
  2. 2The flow waits a configurable bake window, then queries Honeycomb for error rate and p95 latency filtered to the new release.
  3. 3A logic branch compares the metrics against your SLO burn threshold.
  4. 4If healthy, the run ends quietly. If burning too fast, an action calls the Vercel API to promote the previous deployment back to production.
  5. 5A PagerDuty incident is opened with the Honeycomb query link and the rollback details for on-call.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect VercelDeploys, runtime logs, analytics.
  2. 2
    Connect HoneycombDistributed traces and queries.
  3. 3
    Connect PagerDutyIncidents, on-call, escalations.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
