CLIProxyAPI

CLIProxyAPI is a local API bridge for builders who already use coding assistants and want API-shaped access from their development tools. The official GitHub README describes a proxy server that provides OpenAI, Gemini, Claude, Codex, and Grok-compatible API interfaces for CLI-backed services. In practice, that means a script, SDK, evaluation runner, or agent framework can talk to a local endpoint instead of being hard-wired to one provider interface. The project is especially relevant for developers using CLI-first assistants such as Claude Code, ChatGPT Codex, Antigravity, Grok Build, Muse Code, and related tools. Rather than rewriting every client integration, a builder can put CLIProxyAPI in the middle, configure the supported accounts, and point compatible clients at the proxy. That is useful for local experiments, routing tests, side-by-side provider comparisons, and agent loops that expect an OpenAI-style API shape. GitHub listed the repository as router-for-me/CLIProxyAPI, written primarily in Go and released under the MIT license. At the time this profile was created, the repo showed more than 53,000 stars, thousands of forks, and a same-day push on September 25, 2026. The README also recommends EasyCLIProxyAPI for desktop users who want a graphical configuration UI, automatic updates, tray integration, and one-click start or stop. Pricing is recorded as free open-source software because the reviewed entity is the public MIT-licensed repository. That does not make the routed model usage free. Users may still need active subscriptions, API keys, OAuth sessions, provider accounts, or local infrastructure. Teams should budget around the underlying model services, not just the proxy license. The main caveat is credential and network safety. A proxy that touches model credentials and routes requests should be treated like sensitive developer infrastructure. Do not expose it to the public internet by accident. Pin versions, inspect configuration, isolate secrets, and confirm that provider terms allow the intended workflow. OpenTools classifies CLIProxyAPI as a developer tool because the durable value is installable infrastructure for API compatibility and agent development. It is not an LLM and it is not a hosted model gateway by itself. The best first step is to run it in a disposable local environment, connect one low-risk CLI account, and test a single compatible client before expanding to broader routing. For evaluation work, the safest adoption path is narrow. Use a test project, connect one provider, and log only non-sensitive prompts while confirming request and response compatibility. Then add rate limits, local firewall rules, and clear account boundaries. If the proxy becomes part of a team workflow, document who owns credentials, how upgrades are reviewed, and how incidents are handled. That operational discipline matters more than the raw star count because the tool sits directly in the model-request path.
