The honest brief

Gemini CLI

Its free tier serves Gemini 2.5 Pro at a 1M-token context via a personal Google account — unusually generous limits for a terminal coding agent.

  • Apache-2.0 and fully open source
  • Generous free tier via Google account
  • Built-in Google Search grounding + MCP
  • Non-interactive mode for CI scripting
  • Locked to Gemini models
  • Younger ecosystem than Claude Code
  • Free-tier request limits and quota throttling

OpenCode

Fully open-source and provider-agnostic where most agent CLIs are vendor-locked — swap among 75+ providers, including local models.

  • Fully open source
  • Swap among many providers and local models
  • Terminal, desktop, and IDE surfaces
  • No code stored on external servers
  • Quality varies with chosen model
  • Fast-moving, frequent releases
  • Zen's curated models cost extra
