Documentation

API monitoring and error tracking that captures every request and exception automatically. No agents, no sampling, no config files. Add an SDK and everything is recorded: status codes, latency, headers, bodies, client IPs, stack traces. Sensitive data is redacted before it leaves your server.

Supported frameworks

• Node.js: Express, Next.js (setup guide)
• Python: FastAPI, Flask (setup guide)
• Go: net/http, fasthttp (setup guide)

The quickstart takes a few minutes. Or run the wizard:

What you get

• Request capture: every API request recorded with URL, method, status, headers, bodies, latency, client IP. See the full schema.
• Error tracking: uncaught exceptions, panics, 5xx responses captured automatically with full stack traces. No code changes needed.
• Alerts: anomaly detection learns your traffic patterns, fires when something deviates. Email, Discord, Slack.
• Assistant: ask questions about your API data in plain English, get answers with charts. Save charts to dashboards.
• Auto-redaction: passwords, tokens, API keys redacted automatically. Emails partially masked.
