Crush vs OpenCode
Two bring-your-own-key terminal coding agents — a source-available TUI and an MIT-licensed agent — compared across models, extensibility, and automation.
Updated August 28, 2026 · Independent comparison — Crush, OpenCode are separate products.
Crush
Charm's glamorous terminal coding agent
Crush is Charm's terminal-based coding agent, written in Go and released under the Functional Source License (FSL-1.1-MIT): source-available (not OSI open source), but converting to MIT over time. It connects to many providers — Anthropic, OpenAI, Gemini, Bedrock, Copilot, MiniMax, Vercel, and more — and lets you switch models mid-session while preserving context. Crush is LSP-aware, keeps multiple isolated sessions per project, supports MCP servers and agent skills, and adds a crush run command for non-interactive, scriptable use in CI and automation. It ships as a single self-contained binary on macOS, Windows, and Linux.
OpenCode
Anomaly's terminal-first open-source coding agent
OpenCode is an MIT-licensed, terminal-first coding agent maintained by Anomaly, with a polished TUI plus a desktop app and editor extensions for VS Code, Cursor, and Zed. It supports 75+ model providers and BYOK, with an optional OpenCode Zen model gateway and the $10/month OpenCode Go open-weight subscription. It has Plan and Build modes (toggled with Tab), subagents invoked with @, LSP and MCP support, a plugin and skills system, and headless automation via opencode run plus an opencode serve HTTP server and optional web UI. It runs on macOS, Linux, and Windows (WSL recommended).
Bottom line
