Observability and cost tracking for Exo

See every Exo agent conversation, fork, tool call, and token as it happens. ClawMetry detects Exo (exoharness) workspaces automatically and renders conversations, tokens, native per-call cost, and fork lineage in one dashboard.

What ClawMetry sees on Exo

Once ClawMetry is running, your Exo activity shows up as:

• Conversations as sessions: one row per Exo conversation, with the agent it belongs to, started at, last activity, model, message count, and per-session token totals.
• Live activity: every tool call and result as it lands, with arguments, plus the model's reasoning summaries. A tool call shows once, even though Exo journals it in two places.
• Per-turn tokens: prompt, completion, cached, cache-creation, and reasoning token counts on every model call, plus time-to-first-token and call duration.
• Native cost, honestly labelled: Exo prices each model call itself, and ClawMetry shows that exact figure. When Exo could not price a call, ClawMetry prices the tokens and marks the session estimated instead of pretending.
• Fork lineage without double billing: a forked conversation nests under its parent as a child lane, and the history it inherited is billed once, to the parent.
• Any executor: whether the conversation ran on Exo's default executor, Codex, Claude Code, or Cursor, it lands in the same view with the same numbers.

Enable it in about two minutes

1. Install ClawMetry

Pick the line that matches your OS. Windows users: paste the install.cmd line, not the shell one.

# macOS or Linux
curl -fsSL https://clawmetry.com/install.sh | bash

# Windows (cmd.exe or PowerShell)
curl -fsSL https://clawmetry.com/install.cmd -o install.cmd && install.cmd

2. Run the daemon

clawmetry

The daemon auto-detects Exo workspaces on the machine and starts reading immediately. No config, no runtime restart.

3. Open the dashboard

Open http://localhost:8900. Switch the runtime chip to Exo.

The one thing this catches that Exo alone does not

Exo is built to fork, rewind, and let an agent rewrite itself mid-run, and exo repl shows you one conversation at a time. That is exactly when spend stops adding up in your head: a branch inherits its parent's whole history, a self-edited agent starts calling tools in a loop, and three executors share one workspace. ClawMetry watches the whole fleet: cost per hour across every Exo conversation, fork trees with the inherited history billed once, message-repeat detection, and per-session token-growth curves. Set a threshold, and the approval queue pauses before the next call. Kill switch (Pro) stops it.

Starred by the people building AI
