AI Gateway Bookkeeping for the Self-Hosted and Suspicious

What it does

CPA Manager Plus is a management panel and monitoring server for CLIProxyAPI, an OpenAI-compatible AI gateway. It turns the gateway’s usage queue into a local SQLite ledger and surfaces a React dashboard for live request tracking, historical search, and long-running analytics. If you don’t need the database, you can also drop in a single-file panel that talks directly to an existing CPA instance.

The interesting bit

The project treats gateway operations as an accounting problem, not just a routing one. It syncs model pricing from LiteLLM and OpenRouter to estimate spend, automatically disables Codex accounts that hit usage limits and revives them at reset time, and flags stale auth files or revoked OAuth tokens before they silently fail. That is unusually thorough lifecycle management for a self-hosted tool.

Key highlights

• Breaks down cost, tokens, cache usage, latency, and failures by model, provider, account, API key alias, project, and time window.
• Codex-specific health checks cover quota windows, 401 reauth needs, deactivated workspaces, and safe enable/disable/delete suggestions.
• Account-pool safeguards distinguish between auto-disabled limits and manual bans, so automation does not override human intent.
• Ships as a single-file management.html, Docker images, or native binaries for Linux, macOS, and Windows on amd64 and arm64.
• Manager Server mode encrypts the CPA Management Key and gates access behind an admin key; CPA panel mode stays lightweight for existing setups.

Verdict

Worth a look if you self-host CPA or another OpenAI-compatible gateway and are tired of guessing why bills spiked or which auth file died. Skip it if you already have enterprise observability covering AI spend down to the per-account level.
