• Deploy verdict
  Every production deploy ends Cleared, Failed, or Not cleared yet, with the evidence behind it
• Release-to-release baseline
  Compares each release with the last one it cleared, not with the hour before the deploy
• HTTP regression detection
  5xx rate and p95 latency per route, with explicit sample sizes and thresholds
• Exception detection
  New exception fingerprints and spikes in existing ones, stable across deploys
• Background job verification
  Job failure rate and duration regressions, per job class
• Scheduled job monitoring
  Missed or failed recurring runs, during a release and between releases
• Silent failure detection
  Routes, jobs, and webhooks whose traffic collapses while nothing errors
• Worker and agent silence alerts
  Alerts when workers stop picking up jobs or an app stops reporting
• Clearance report
  What was exercised, what wasn't, and what DeployAngel is still watching
• Latency watch
  Keeps comparing latency through the release's first day and alerts on late regressions
• Critical flows and checkpoints
  Name the paths that matter more than their traffic suggests and verify they ran
• Human-only acceptance
  An intentional drop is accepted by a person on the dashboard with a reason, never by an agent
• AI investigation
  Optional explanation of a failure, run only after the deterministic rules have found it
• Rollback guidance
  Names the last cleared release and the migrations a rollback would cross
• Coding agent integration
  CLI, MCP server, and CI exit codes so an agent can wait on the verdict
• GitHub integration
  GitHub Action for deploy pipelines and commit checks on the repository
• Notifications
  Slack, email, PagerDuty, signed webhook, Honeybadger Insights, AppSignal markers
• Deploy detection
  Automatic on Heroku and GitHub Actions, one-line deploy hook anywhere else
• Staging promotion
  Tracks a release from staging to production and shows the staging verdict
• Shareable release pages
  Public read-only link to any release's verdict and report
• Fire drill
  Tests the whole alert path without sending traffic or writing telemetry
• Open-source agents
  MIT-licensed for Rails, Hanami, Sinatra, Django, FastAPI, Flask, and ASP.NET Core
• Privacy by design
  Aggregated counts and histograms only, no request bodies, parameters, cookies, or logs
• Hands off production
  Never sends traffic to your app and never rolls anything back
