sentry_sdk.init( dsn="https://abc@o0.ingest.sentry.io/123", dsn="https://abc@eye.santiyepro.com/123", )
Pivot from a replay to the error to the trace to the log — in one click.
Automatic grouping, regressions, suspect commits, and source-mapped stack traces.
Web (rrweb) and mobile video replay, stitched seamless, with a synced activity timeline and touch overlay.
Distributed span waterfalls with autogrouping and one-click pivots to errors and logs.
Structured, searchable, live-tailing logs correlated to traces and replays.
Spikes, new issues, regressions, crash-free drops — to Slack, email, webhook, or Telegram.
Adoption, crash-free sessions/users, and regression tracking across every deploy.
Runs entirely on your Cloudflare account — Workers, D1, R2, Durable Objects. You own the data and the bill.
