Open-source terminal agent (MIT)

FreeAI IDEs & coding agentsopencode.ai

What it is

An MIT-licensed terminal agent from Anomaly, and the breakout open-source success of the era with well over 150k GitHub stars. It runs in the terminal, a desktop app or an IDE extension, drives 75+ providers through Models.dev, uses LSP for real language awareness, and runs several sessions in parallel.

Why it earns a slot

The vendor-neutral default when you want Claude Code ergonomics without the vendor. Shareable session links make debugging an agent run collaborative, and it has become the harness other products build on, including Roomote.

Know before you commit

Optional OpenCode Zen credits start at a $20 top-up; the agent itself is free but you are always paying some model provider.
