The OpenTelemetry Wave

The OpenTelemetry adoption wave across its target languages

The future-proof OpenTelemetry (OTel) observability standard has created a major industry shift. OTel breaks vendor locks and reduces costs while offering interoperability. Dart is the last of OpenTelemetry's 15 target languages to get an OTel SDK. Finally, the power of OpenTelemetry is available for Dart and Flutter.

PRO OTEL FOR DART AND FLUTTER

Dartastic Native OTel SDKsDartastic OTel

Break Heisenberg's Law — observe without affecting performance.

  • Move OTel to native threads. Observability shouldn't cost you frames.
  • Never Lose a Crash. Native catches errors that Dart can't.
  • Jank Attestation. Know which widget is too busy.
  • Metrics for Mobile and Server — see what your users actually feel.
  • Automatic PII scrubbing — emails, IPs, auth tokens, SSNs, credit cards redacted before they are saved in your platform.
  • Compatible with any OpenTelemetry stack. Use with Dartastic Observatory or bring your own OTel-compliant platform.

PRODUCTION ERRORS → SOURCE-CODE LINES

Dartastic SymbolizerDartastic Symbolizer

Dartastic Symbolizer turns production errors into actionable source-code lines, privately.

When the Native SDK detects an error, it can call Dartastic Symbolizer and augment the error with its source code location. Your o11y platform gets the error with a finger pointing to a line of source code, automatically.

Debug symbols (or source maps) + your app = your source code. Uploading them to your observability vendor adds an attack surface for your IP, and devops pain on top of it.

Keep your symbols where you publish packages, in Dartastic Pub, where you control who sees your IP.
