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.
What is Buildkite?
Buildkite is rebuilding its CI surface so agents, not just humans, can drive and diagnose builds.
Buildkite is a CI/CD platform whose recent work points squarely at machine consumers. The last ten entries cluster around exposing more build, job, and runner context through the REST and GraphQL APIs and the MCP server, alongside steady build-page UX work. The throughline is making pipeline state legible to agents, CLI tools, and MCP clients.

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.
Buildkite
6.3INFRA · APIS
Buildkite is rebuilding its CI surface so agents, not just humans, can drive and diagnose builds.
◆ Current state
Buildkite is a CI/CD platform whose recent work points squarely at machine consumers. The last ten entries cluster around exposing more build, job, and runner context through the REST and GraphQL APIs and the MCP server, alongside steady build-page UX work. The throughline is making pipeline state legible to agents, CLI tools, and MCP clients.
◆ Where it's heading
The direction is an agent-operable CI plane: signal and signal_reason for failure triage, MCP write tools for cluster and schedule management, headless token auth, and runtime job controls like self-adjusting timeouts. Buildkite is treating automated callers as first-class operators of the system, not just readers.
◆ Prediction
Expect continued expansion of MCP write capabilities and API-exposed runner context, with more of the agent flows currently in preview moving toward general availability.
