About
shim sits between your code and the model and masks personal data and secrets before a prompt leaves, then shows what every call carried and cost. shim-cli is free and open source, runs on your own machine next to Claude Code, Codex, Copilot CLI and VS Code, and needs no account. For apps there is an AI Gateway, one base URL in front of OpenAI, Anthropic and Gemini that also handles PDF, Word and Excel files, plus an Enterprise version on your own servers. Free to start.
