What is Bugsnag?

BugSnag's centre of gravity has shifted from crash reports to performance spans and system metrics.

BugSnag ships one dated digest a month, and for the past six the bulk of the content has been Performance, not error monitoring: span groups, session windows, pre-main iOS start times, and CPU/memory/rendering metrics. Error monitoring still gets work, but it reads as maintenance — filter operators, App Hang detection, HTTP error capture — while the new surface area lands in the Performance product. Flutter has been pulled up to iOS/Android parity over two consecutive releases. A self-hosted MCP server sits alongside all of it, gaining OAuth and write actions rather than staying a read-only lookup.

What is Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

BugSnag's centre of gravity has shifted from crash reports to performance spans and system metrics.

◆ Current state

BugSnag ships one dated digest a month, and for the past six the bulk of the content has been Performance, not error monitoring: span groups, session windows, pre-main iOS start times, and CPU/memory/rendering metrics. Error monitoring still gets work, but it reads as maintenance — filter operators, App Hang detection, HTTP error capture — while the new surface area lands in the Performance product. Flutter has been pulled up to iOS/Android parity over two consecutive releases. A self-hosted MCP server sits alongside all of it, gaining OAuth and write actions rather than staying a read-only lookup.

◆ Where it's heading

The product is converging on a single app-health telemetry store where an error, a span, a session, and a device metric are all queryable against each other — Correlated Events in April was the clearest statement of that, and July's per-session aggregated CPU and memory extends it to resource cost. The SDK is becoming the control surface: developers define their own session windows and delivery strategies rather than accepting BugSnag's defaults. The MCP work is the quieter arc, moving from token-based reads to OAuth logins and mutating actions like snoozing errors and linking Jira issues.

◆ Prediction

Expect the Sessions tab to gain the same correlation treatment errors got — jumping from a session window straight to the events and spans inside it. The MCP server is the thing to watch: it has been given auth and write actions in consecutive digests, which points at more triage operations exposed to agents next.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
