What is Buildkite?

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

What is Umbrel?

umbrelOS 2.0 Beta ships virtualization, iOS/Mac companion apps, multi-user, and MCP server — redefining the personal home server.

umbrelOS 2.0 Beta 1 is Umbrel's biggest release to date. The headline additions: Machines (run Windows, Ubuntu, Debian, Android in a browser via one-click install), iOS and Mac companion apps (automatic camera roll backup, Finder integration), multiple user accounts with per-user private home folders, a built-in MCP server for AI agent access, Storage Manager with FailSafe RAID, GPU passthrough for NVIDIA/AMD/Intel, and cloud storage downloads from Dropbox, OneDrive, iCloud, and others. The 1.7.x line is now in maintenance, receiving only security patches (DirtyFrag CVEs, CopyFail CVE).

Buildkite makes caching a built-in agent primitive and puts test workflows into Terraform.

◆ Current state

Buildkite is a CI/CD platform that combines a hybrid agent model with a growing Test Engine. Its October releases include built-in caching (now GA), Terraform and REST management of Test Engine workflows, queue-filtered webhooks and cluster-level OpenTelemetry. The product is filling infrastructure gaps that teams previously solved with plugins or custom images.

◆ Where it's heading

The pattern is to centralize and codify: settings move from individual agents to clusters, and from the UI to Terraform and APIs, and capabilities such as caching move from plugins into the agent itself. Test Engine is turning into a programmable flaky-test management layer instead of a dashboard.

◆ Prediction

Expect more Test Engine monitors and actions that can be managed in code, and cache controls such as eviction and scoping, now that Cache is GA.

umbrelOS 2.0 Beta ships virtualization, iOS/Mac companion apps, multi-user, and MCP server — redefining the personal home server.

◆ Current state

umbrelOS 2.0 Beta 1 is Umbrel's biggest release to date. The headline additions: Machines (run Windows, Ubuntu, Debian, Android in a browser via one-click install), iOS and Mac companion apps (automatic camera roll backup, Finder integration), multiple user accounts with per-user private home folders, a built-in MCP server for AI agent access, Storage Manager with FailSafe RAID, GPU passthrough for NVIDIA/AMD/Intel, and cloud storage downloads from Dropbox, OneDrive, iCloud, and others. The 1.7.x line is now in maintenance, receiving only security patches (DirtyFrag CVEs, CopyFail CVE).

◆ Where it's heading

2.0 is a category expansion, not an iteration. Umbrel started as a personal Bitcoin node host, broadened to a privacy-focused app server, and is now positioning as a full personal home server OS — with virtualization, AI agent integration, and first-party client apps. The MCP server is particularly telling: it makes an Umbrel unit a computer an AI agent can use, not just a server a human visits.

◆ Prediction

2.0 will ship final with Google Drive support (explicitly flagged as coming soon). The MCP server will expand its permission model and more apps will expose MCP-compatible interfaces. The companion apps will gain remote access features beyond Tailscale.
