Anvil vs Gemini CLI

Anvil: Anvil is an open-source, self-hosted AI coding agent that provides a provider-agnostic LLM development pipeline. It allows developers to build, review, and ship code using various models across different stages, optimizing costs by routing tasks to the cheapest or most suitable provider for each step.; Gemini CLI: Gemini CLI is Google's open-source AI agent for the terminal, providing direct access to Gemini models with a free tier of 60 requests/minute and 1,000/day. It ships with built-in tools for Google Search grounding, file operations, shell command execution, and web fetching, plus native MCP support for custom integrations. Built for developers who work primarily in the command line.

When to choose:
  • You want an Apache-2.0 terminal coding and task agent from Google with a generous free tier using a personal Google account.
  • You want built-in file editing, shell execution, Google Search grounding, MCP server support, and a GitHub Action for CI.
When to skip:
  • You want to switch freely between Claude, OpenAI, DeepSeek, and local Ollama models inside the same terminal agent; Open Interpreter supports any OpenAI-compatible provider.
  • You prefer a graphical desktop workspace over a command-line interface; AionUi or Cherry Studio provide GUI clients.
