Apache Casbin Gateway, a subproject of Apache Casbin (Incubating)

See what every AI coding agent on your machine is doing

and whether the API behind it is the one you paid for.

One local gateway for Claude Code, Codex, Cursor, Gemini CLI and the rest: the providers they talk to, what they may do and what they spend.

Get started GitHub

$ curl -fsSL https://raw.githubusercontent.com/apache/casbin-gateway/master/scripts/install.sh | bash

One command. No database, no Go, no Node, no configuration.

Is that API key what it was sold as?

A reseller can serve a cheaper model, fake a cache hit, or quietly drop a parameter it claims to support. Authenticity probes every provider on its own and grades it A–F.

What every agent did, spent and sent

Every prompt and tool call, the spend read from the agents' own transcripts, and on Windows, where each agent's own processes upload data.

One place for all of them

Point every agent at any of 44 model vendors, say what each may do, and install, upgrade or roll back the agents themselves.
