OpenCLI

OpenCLI is an open-source tool that exposes any website or Electron application as a command-line interface. By leveraging Chrome DevTools Protocol (CDP), it enables direct browser control from the terminal without injecting credentials or tokens. This makes it ideal for developers and AI agents who need reliable, deterministic web automation that reuses existing browser sessions. The tool is designed primarily for developers building automation pipelines, AI agent frameworks, or CI/CD workflows that interact with web interfaces. It supports both browser automation (clicking, typing, extracting, screenshotting) and desktop Electron app control (e.g., Cursor, Codex, ChatGPT). OpenCLI operates without consuming any LLM tokens at runtime, making it cost-effective for high-volume tasks. What sets OpenCLI apart is its security model: it reuses Chrome's logged-in state directly, so credentials never leave the browser. There are no tokens to expose and no password storage. Additionally, it provides deterministic output—the same command produces the same result every time, which is critical for scripting and CI integration. OpenCLI also includes AI agent adapters that allow automatic discovery and writing of new adapters, creating a repeatable loop for reconnaissance, extraction, and verification. It is released under the Apache-2.0 license and maintained by the open-source community.
