Inspect your training runs, from a browser or your coding agent.
Three panes, one local server.
arkor dev launches a local Hono server with a Vite-built UI. Browse your training jobs, inspect metrics as they stream, and prompt any checkpoint from a playground without leaving your laptop.
Jobs
Every training run, with status, base model, and dataset at a glance.
Metrics
Loss curves and per-step events stream in as the run progresses.
Playground
Pick any checkpoint and chat with the in-progress adapter from a local UI.
Studio works without opening a browser tab.
Claude Code, Cursor, and other coding agents can read Studio state directly. Ask your agent how a run is going and it will tell you, with the actual job metrics in context.
Reference docs ship inside the arkor npm package, so your agent already knows how to write training code against the SDK. No external context fetch required.
