Casbin Gateway
Casbin Gateway is a local dashboard and proxy that shows what every AI coding agent on a machine is doing, grades whether an API key's provider matches what was paid for, and centralizes model access, permissions and spend tracking across 44 vendors.
Casbin Gateway runs on a developer's own machine and puts every coding agent, such as Claude Code, Codex, Cursor and Gemini CLI, behind one endpoint that can reach 44 model vendors. It records each agent's prompts, tool calls and spend by reading the agents' own transcripts, and on Windows can also see where an agent's own process uploads data outside any proxy.
Its authenticity check probes a provider on its own, grading it from A to F to flag a reseller that might serve a cheaper model, fake a cache hit, or silently drop a supported parameter, and it can grade a single endpoint without installing anything else. It also installs, upgrades or rolls back the coding agents themselves.
Installation is a single script for Linux, macOS or Windows; the app runs with no sign-in, stores its data in a local SQLite file, and can also run headless as a background server.
