OpenCode is the 2026 open-source breakout in agentic coding CLIs. Launched March 2025, crossed Cline and OpenHands in GitHub stars by April 2026 (140K+), closing the gap on Aider. Go-based TUI with built-in plan mode, MCP support, and provider-agnostic backends (75+ providers including local Ollama). Indie Bench’s next-up evaluation candidate because it’s the easiest harness for autonomous evaluation — single Go binary, no IDE runtime, zero auth friction.
