OpenCode

OpenCode has quickly become one of the most prominent open-source coding agents, with a strong terminal-first experience. A major strength is model flexibility: it supports hosted frontier models, self-hosted endpoints and local models. This makes OpenCode attractive for cost control, customization and restricted environments including air-gapped setups. It also means users need to be explicit about licensing and provider terms when using subscriptions or APIs.

OpenCode’s extension model is another key part of its appeal, supporting both plugins and MCP integrations for team-specific workflows, tools and guardrails. Many users leverage on Oh My OpenCode, an optional but popular harness that provides a more opinionated, batteries-included setup with coordinated agent teams and richer orchestration patterns.
