Agent safety · open beta

Ship agents you actually trust.

Chronoly records every agent action, enforces OS-level boundaries, and stops runaway loops before they burn budget.

Platform

Three tools. One runtime.

Blackbox records. Shield enforces. Cost Guard kills loops. Use one or all three.

Blackbox tracing

Every prompt, tool call, file change, and command recorded as a replay-grade timeline — not chat history.

  • →Prompt + response log
  • →Tool-call chain
  • →File diff + rollback
  • →Session replay

OS-level shield

Boundaries at the OS and network layer. Rules agents cannot prompt-bypass.

  • →Per-path write guard
  • →Network filter
  • →Command sandbox
  • →Per-tool policies

Cost guard

Loop detection, per-task token budget, and a circuit breaker when a session runs away.

FAQ

Questions

Does it slow down my agent?+

Under 2ms overhead per tool call. Async logging, non-blocking checks.

What agents does it work with?+

Claude Code, Cursor, Hermes, OpenAI Codex, and any OpenAI-compatible proxy that calls tools, shell, or files.

Can I self-host?+

Yes. Local or your cloud. No data leaves the machine unless you opt into cloud features.

Is this just another dashboard?+

Dashboards show what happened. Chronoly also blocks what should not happen — at the OS layer, not the prompt layer.
