The difference is who carries the pager. A concrete decision framework covering cost, ops load, compliance, and scale ceilings. Observability Guides https://tracepath.dev/blog/flutter-session-replay-internals https://tracepath.dev/blog/flutter-session-replay-internals Thu, 17 Sep 2026 00:00:00 GMT rrweb records the DOM. Flutter has no DOM. Here is how we rebuilt session replay for Flutter on top of the widget tree, and what the privacy trade-offs look like. Engineering Product https://tracepath.dev/blog/otel-collector-guide https://tracepath.dev/blog/otel-collector-guide Tue, 15 Sep 2026 00:00:00 GMT Where the tracepath-otel-agent fits in your pipeline, how to configure it for batch-and-forward, and when you should put a full OpenTelemetry Collector in front of it instead. Guides Observability https://tracepath.dev/blog/sqlite-observability-week-two https://tracepath.dev/blog/sqlite-observability-week-two Sat, 12 Sep 2026 00:00:00 GMT The follow-up to our SQLite observability benchmark: a full week of production-shaped traffic against the single-binary stack, with the failure modes nobody benchmarks for.

Here is what actually happens between a browser stack trace and a readable one: VLQ mappings, debug IDs, and why symbolication is a cache problem. Guides Engineering https://tracepath.dev/blog/what-is-apdex https://tracepath.dev/blog/what-is-apdex Tue, 08 Sep 2026 00:00:00 GMT Apdex turns thousands of request latencies into one number your PM can read. How the math works, where the thresholds come from, and how TracePath ranks endpoints by Apdex.

When you order the same meal twice, you expect the same meal twice. That predictability is what makes them reliable. A distributed system needs the same property.

In this tutorial we'll catch a production error, open an issue, and set up an automatic workflow that runs Claude Code to investigate and fix the root cause. When it's done it will open a PR linked to the original bug, or leave a comment explaining why the issue could not be automatically addressed.
