HOL GuardOpenObserve

Bottom line: HOL Guard for developers running autonomous coding agents; OpenObserve for teams running agents in production.

HOL GuardHOL Guard

An open-source (Apache-2.0), local-first runtime control that intercepts risky AI coding-agent actions and lets you allow, ask, or block them, with optional paid cloud sync.

Best for
  • developers running autonomous coding agents
  • teams wanting shared runtime policy
  • Teams running agents in production
  • Platform teams already using OpenTelemetry
  • Organisations needing LLM cost attribution
Pros
  • Core runtime is open source (Apache-2.0), free, local
  • Allow/ask/block before an action has side effects
  • Works across many coding agents
  • Vendor is candid about coverage limits
  • Agent traces are standard OpenTelemetry spans, not a silo
  • Per-span token cost from your own model pricing
  • Unlimited users with no per-seat charge
  • AGPL-3.0 core with a self-hosted option
  • Self-hosted enterprise free up to 50 GB per day
Cons
  • Coverage is harness- and event-specific
  • Explicitly not a firewall or complete prompt-injection preventer
  • Many headline metrics are self-reported
  • Strongest team value sits behind paid cloud
  • LLM observability is labelled preview
  • Online evaluations are an enterprise feature
  • Ingestion-based pricing needs volume forecasting
  • Self-hosting carries operational overhead
  • Payload capture raises data governance questions
