aider vs opencode
AI coding assistants for terminal-based development compared
aider and opencode both bring AI assistance into software development through a terminal interface. aider focuses on pair programming across repositories with a range of models and Git workflows, while opencode provides distinct build and read-only plan agents, plus a beta desktop app.

aider: Pair Program with AI in Your Terminal
Aider is a terminal-based AI coding assistant that works with existing repositories or new projects. It helps developers make code changes with cloud or local language models while keeping edits and version control in their workflow.

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.

Key differences
- aider supports hosted and local language models and offers a copy-and-paste workflow for web chat; opencode centers on its build, plan, and general agents.
- aider maps repositories for model context and supports more than 100 programming languages; opencode highlights code exploration and planning with a read-only agent.
- aider integrates with Git, can commit changes, and can run linters and tests; opencode distinguishes a full-access build agent from a read-only plan agent.
- aider is written in Python and uses the Apache-2.0 license; opencode is written in TypeScript and uses the MIT license.
- opencode offers a beta desktop app for macOS, Windows, and Linux; aider is described as a terminal-oriented tool.
- aider’s considerations emphasize model access and reviewing generated edits; opencode’s emphasize agent permissions and the beta status of its desktop app.
Choose aider if you…
- want to work with cloud or local models in a terminal-based pair-programming workflow.
- need repository mapping, Git integration, or help running linters and tests after edits.
- prefer model flexibility, including a copy-and-paste workflow with web chat interfaces.
Choose opencode if you…
- want separate full-access build and read-only plan agents for coding and code exploration.
- prefer an option to try a beta desktop app on macOS, Windows, or Linux.
- want installation routes such as npm, Homebrew, Scoop, or an install script.
