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 Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.

Bugsnag
2.5INFRA · APIS
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.
Merge
6.3INFRA · APIS
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
