opencode vs Pi
AI coding agents compared
opencode is an open source coding agent with build and read-only plan agents, while pi combines a coding-agent CLI with a toolkit for building and customizing agents. opencode provides defined agent roles and a beta desktop app; pi emphasizes extensibility, provider choice, and automation.
opencode: Work with an Open Source AI Coding Agent
OpenCode is an open source AI coding agent for developers who want AI assistance in their coding workflow. It offers build and read-only plan agents, a terminal UI, and desktop apps in beta.
Pi: Build and Customize a Coding Agent
Pi is a minimal, extensible coding-agent harness built with TypeScript and its pi-ai unified LLM API. Run it as a CLI on macOS, Linux, or Windows, or adapt its components and extensions to your own workflows.

Key differences
- opencode includes a full-access build agent and a read-only plan agent; pi omits plan mode and sub-agents by default, with options to add features through extensions or packages.
- pi provides a unified API for multiple LLM providers, an agent runtime, and a TypeScript SDK; opencode focuses on using its coding agent through a terminal UI or beta desktop app.
- opencode offers a general subagent for complex searches and multistep tasks; pi provides customization through extensions, skills, prompt templates, themes, and packages.
- pi supports print and JSON modes, RPC, and libraries for building or automating applications; opencode documents agent configuration and use.
- Both projects are written in TypeScript and use the MIT license. opencode lists 212k stars and 28.1k forks, while pi lists 112k stars and 14.2k forks.
Choose opencode if you…
- want distinct build and read-only plan agents for coding and code exploration.
- prefer a terminal UI with the option of a beta desktop app.
- need a general subagent for complex searches or multistep tasks.
Choose Pi if you…
- want to customize agent tools, prompts, and interface for your workflow.
- need a multi-provider API, TypeScript SDK, or agent runtime for applications.
- want scripting and integration options such as print or JSON modes and RPC.
