Wide awake.
Barn Owl watches build health, performance, and infrastructure usage around the clock—so a slow regression doesn’t become your next surprise.
A frontier AI lab uses Hermetiq to analyze 2M+ builds and 4B+ build events every day.
Read the customer story →A failed build. A one-line fix.
Follow a real run: Hermetiq surfaces the failed action, Codex fixes its inputs, and Bazel verifies the result.
Step 1 of 4
A file exists locally. The remote action cannot see it.
The release-manifest action exits 1 on Buildbarn. Hermetiq records the failed invocation and action.
Read the build logfailure.log (excerpt)text
Executing genrule //:release_manifest failed: (Exit 1)
cat: build-mode.txt: No such file or directory
ERROR: Build did NOT complete successfully
Inspect the run and reproduce it
An intentionally introduced missing input in a small public sample. Hermetiq supplied the failed-action evidence; Codex applied the patch and reran Bazel. This is a recorded client-assisted workflow, not a customer benchmark.
See the whole build system.
Connect each slow build to the actions, cache misses, queues, and workers behind it. Give your engineers and AI agents the evidence to act.
Bazel profiles, Buildbarn telemetry, and infrastructure costs in one place.

An AI build engineer. Part of Hermetiq.
Meet Barn Owl.
It watches your builds, catches the regressions, and earns the trust to fix them. You get your product engineers back.
Knows your build.
It connects a failed build or slowdown to the work and infrastructure behind it. Answers from your actual build history, not generic advice.
Earns your trust.
Explanations first. Recommendations next. Then fixes as PRs you review and merge. More autonomy only where you grant it—never the keys to prod by default.
Gets wiser.
Every build outcome is another lesson in your stack’s failure modes. The owl learns what actually worked, not just what sounded plausible.
Built for production.
Built for teams building products
Give your engineers more time to ship.
More services, more dependencies, more code from your agents. Hand off build operations so your engineers can focus on moving your product forward.
Explore managed buildsDo we need to use Bazel already?
No. We assess your codebase, dependencies, toolchains, and migration effort before onboarding. The agreed workload needs a supported Bazel build before Hermetiq can operate it. We agree the setup and operating scope with you first.
Why not just CI and a coding agent?
Those are tools your team operates. Hermetiq takes responsibility for establishing, operating, and optimizing the supported build system underneath them. Your engineers keep ownership of product code, tests, and change approvals.
What about infrastructure costs?
Connect build activity to infrastructure usage so you can see where resources go. Barn Owl watches for wasted work and over-provisioned capacity, helping you plan instead of guessing at the next bill.
