Synthwave intercepts errors before your users notice. Real-time traces, smart alerts, and full context — zero config required.
Trusted by engineering teams at
Synthwave surfaces the issue, shows you exactly what went wrong, and points you to the line of code that needs fixing.
Catches errors, unhandled rejections, and slow queries the moment they fire. Zero-config, sub-millisecond overhead.
Traces the full request across services, workers, and APIs. Pinpoints the exact commit, file, and line.
Assigns to the right owner via CODEOWNERS. Pings Slack or PagerDuty. MTTR drops from hours to minutes.
Synthwave cut our mean time to resolution from 45 minutes to under 7. It's not a nice-to-have anymore — it's infrastructure.
Watch your production environment in real time. Errors, warnings, and deployments — all in one stream.
Drop Synthwave into any Next.js, Express, or FastAPI app. No agent. No YAML. Just import and ship.
