Aspect Cloud is live.

A hosted Bazel remote cache shared by CI and every developer, with every build in the Build Results UI. Free to start. Come see it, and our talks, in Amsterdam.

What’s new

What we’re launching

Each has a short brief: what it is, what problem it solves, and what changes for you.

01New

Aspect Cloud

A hosted remote cache shared by CI and every developer, with every build in the Build Results UI. Log in, add a flag, and your first build shares cache hits. Free to start.

02New

Build Results UI

Every build, local or CI, explained: why it was slow, what the cache did and why it missed, which test is actually flaky, and what changed between two builds.

03New

Build Trends

Rank every target by P90 wall time, critical-path share, cache hit rate, flake rate or pass rate over a day to a year, and see each as a trend.

04New

CLI, AXL & MCP

The Aspect CLI, tasks written in AXL (Starlark), and an MCP server that gives Claude Code, Codex and Cursor structured build results instead of log text.

Add every session to your calendar (.ics). Times are CEST (UTC+2) and, like room assignments, may change. The official BazelCon schedule is the source of truth. Training Day sessions need pre-registration.

Meet us
