A browser grid that spent the summer becoming a team product, and is now opening itself to agents.
TestingBot runs a cross-browser and real-device cloud, and the last three months have gone almost entirely into what surrounds a test run rather than the run itself: custom roles enforced identically in dashboard and API, service accounts so pipelines stop borrowing a person's credentials, enforced two-factor authentication, comments with @mentions on failed runs, one-click filing into GitHub, Jira, Trello, Asana or Azure DevOps, and a notification inbox tying it together. The grid work continues underneath — WebRTC streaming for iOS simulators, a rebuilt web inspector, new devices and browser versions on the usual cadence.
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.

Two directions are visible. The platform is being made safe for organisations rather than individuals, which is what roles, service accounts, 2FA and audit-friendly reporting add up to. Alongside it, the grid is being made reachable by software instead of people: an Insights API exposing pass rates and flakiness, embeddable build reports for CI dashboards, GitHub checks on every pull request, and now Vibium's CLI and MCP server pointed straight at the grid over WebDriver BiDi. The AI work so far reads results — failure analysis, documentation questions — while Vibium is the first path where something other than a human-written script drives the browser.
Expect the agent-facing path to be developed further, since supporting Vibium's MCP server without extra configuration is a small step from offering a first-party one, and expect the device and browser catalogue to keep rotating on its established cadence.
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.
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.
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.
