Hermetiq for Bazel and Buildbarn

Debug Bazel builds without spelunking logs.

Hermetiq turns Bazel build events and connected cache, Buildbarn, and infrastructure telemetry into one queryable record for engineers and AI coding agents.

Answers, not another log viewer

Go from “CI failed” to the evidence needed to investigate it.

Hermetiq correlates signals across the build graph and execution infrastructure so you can investigate the system as one workflow.

Find the failing action

Move from a failed target or test to the recorded action, rule, input, command, configuration, and execution evidence.

Explain the cache miss

Compare action keys, commands, declared inputs, platforms, and environment evidence instead of guessing from logs.

Unblock remote execution

Separate scheduler queue time, worker saturation, uploads, downloads, and execution time across your RBE fleet.

Give your AI agent context

Let Codex, Claude, and other MCP-compatible agents query build history and investigate failures with structured evidence.

Built from your telemetry

Connect the signals your build infrastructure can provide.

Keep Bazel and your execution backend. Configure Build Event Protocol ingestion first, then add supported cache, completed-action, metric, trace, or cost sources for the views you need.

  • Bazel Build Event Protocol (BEP)
  • Remote-cache events when connected
  • Buildbarn completed-action records
  • OpenTelemetry metrics, logs, and traces when connected

Agent-ready through MCP

Let your coding agent investigate the build.

Hermetiq makes build history and failure evidence queryable through MCP, so an agent can inspect what ran, explain what changed, and recommend its next action.
