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 Agent Handler catalog now carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy. Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
What is Trunk?
Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.
Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.
Merge vs Trunk: editorial side-by-side
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 Agent Handler catalog now carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy. 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.
Trunk
0.0INFRA · APIS
Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.
◆ Current state
Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.
◆ Where it's heading
Trunk is making Merge Queue programmable and observable: APIs, IaC, metrics endpoints, and richer dashboards point at customers who manage CI at scale and want it wired into their existing tooling. Flaky Tests is gaining automation hooks (Jira issue creation, configurable threshold monitors) that move it from detection toward workflow.
◆ Prediction
Expect continued API, metrics, and integration depth on Merge Queue, and more automated remediation paths for Flaky Tests, as Trunk leans into programmability for larger engineering orgs.
