Agentic Index
Aider vs Goose (2026)
Both are free, open source, local first, and model agnostic; the split is scope. Aider is a focused pair programmer for editing code in a git repository. Goose, created at Block and now governed under the Linux Foundation, is a general agent that also handles research, automation, and data work, with desktop, CLI, and API surfaces and deep MCP roots.
