DeployCanary

DeployCanary is a web app (with a lightweight CLI agent) that automatically validates deployments using real production signals. It connects to your existing observability stack (metrics, logs, traces) and runs a short, opinionated “canary checklist” after each deploy: error-rate deltas, latency regressions, saturation, and key business KPIs if available. It then produces a simple go/no-go recommendation with a confidence score and a human-readable explanation of what changed and where. This isn’t a full APM replacement; it’s a focused deployment guardrail that teams can adopt without replatforming. The product is realistic if it stays narrow: integrate with a few common stacks, provide clear rollback triggers, and reduce noisy alerts. The value is preventing incidents caused by risky releases, which is still one of the most common sources of outages.
