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 ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week

Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.

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 ships Agent v4, a VS Code extension, and MCP write-access to secrets in the same week

◆ Current state

Buildkite is expanding on three fronts simultaneously. Agent v4 — the first major version since 2018 — is now the stable release, clearing eight years of deprecated behavior. The MCP server gained cluster secret creation, test-suite attribution, and build-failure summaries. And a VS Code extension now surfaces pipelines, live job logs, agent status, and YAML validation without leaving the editor.

◆ Where it's heading

Two threads are running in parallel: hardening the core agent (v4, ephemeral job acquisition tokens, 1 GiB log quota) and expanding the agentic surface (MCP tools for secrets, test attribution, step uploads, failure summaries). The VS Code extension opens a third front — IDE-native CI — that no major CI platform currently owns. The combination points toward Buildkite positioning as infrastructure for AI-driven developer workflows, not just pipeline execution.

◆ Prediction

The MCP server will keep acquiring write operations — secret creation is already there, pipeline modification is the next logical step. The VS Code extension will likely gain pipeline creation and editing to close the IDE-native CI loop.
