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.
What is Unkey?
Unkey is racing to harden Deploy into a credible Vercel/Fly alternative.
Unkey has spent April and May turning Deploy from a demo into a usable platform: public beta launch alongside a $4.5M seed and a website refresh, plus autoscaling, ephemeral disks, build cancellation, fork-PR previews, and a CLI deploy path. The trajectory is clearly capability parity with established container-PaaS competitors. Original API key management work (CLI for keys, identities, rate limits) continues underneath but is now secondary to Deploy.

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.

Unkey is racing to harden Deploy into a credible Vercel/Fly alternative.
◆ Current state
Unkey has spent April and May turning Deploy from a demo into a usable platform: public beta launch alongside a $4.5M seed and a website refresh, plus autoscaling, ephemeral disks, build cancellation, fork-PR previews, and a CLI deploy path. The trajectory is clearly capability parity with established container-PaaS competitors. Original API key management work (CLI for keys, identities, rate limits) continues underneath but is now secondary to Deploy.
◆ Where it's heading
Deploy is the company's central bet now and the cadence reflects it: weekly feature drops covering compute, storage, and ops controls. The seed round explicitly funds the path from code to production API, and the editor of choice is moving from the dashboard to the CLI. Expect the security/rate-limit heritage to fold into Deploy as differentiation versus generic container hosts.
◆ Prediction
The next directional move likely connects Deploy with Unkey's API-key and rate-limit primitives natively, so deployed apps get gateway-grade controls out of the box. A custom domains and TLS story plus more region coverage seem imminent.
