CC One is a desktop application that turns the local session logs of AI coding CLIs into usage analytics — tokens, cost, trends and sessions — and manages their provider configurations. Data is stored locally in SQLite. When multi-device sync is enabled, data is exchanged through a private Git repository that you own; the access token never leaves the machine.
- Five perspectives: overview, devices, projects, sessions and requests.
- Token accounting in four buckets — input, output, cache creation, cache read — with cache hit rate, request counts and cost.
- Usage trends, daily request volume, turn and duration distributions, model share, device and project rankings.
- Request-level log with per-request cost breakdown (input / output / cache read / cache write, billed model, stop reason).

- Sessions navigated by project, group or favorites; batch favorite, group and delete.
- Full transcript reading with turn navigation, in-session search and message copy.
- Local groups stay on the device; favorites and favorite groups sync across devices.
- A separate provider pool per app, with one active provider per app (OpenCode is managed additively: multiple providers coexist in its config).
- Built-in configuration presets, model role mapping (including Claude Code's 1M-context flag), and per-app shared config snippets merged under provider precedence.
- Switching rewrites only the fields the provider owns; all other fields in the config file are preserved. Writes are atomic, backed up, and idempotent when nothing changed.
- Import from CC-Switch and from live config files.
- Data is exchanged through a private Git repository you own, over HTTPS with a personal access token; the token is stored only on the machine.
- Usage data, favorited sessions, favorite groups and the per-device file library are versioned in the repository, namespaced by device.

A compact card pinned to the screen edge shows today's consumption at a glance — token buckets, cache hit rate, requests and cost — and tucks itself away when the main window is minimized to the tray. |
- Configurable model pricing: built-in price table, custom entries, LiteLLM fetch, import and export.
- Per-device file library, versioned through the sync repository.
- In-app auto-update via GitHub Releases.
- English / 日本語 / 中文 interface; light and dark themes with accent skins.
- Runs in the system tray with background collection.
