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 Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

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.
Knock
6.3INFRA · APIS
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
