OpenCode is an open-source coding agent for the terminal. Its built-in build agent handles development work, the plan agent is read-only for analysis and exploration, and a general subagent supports complex searches and multistep tasks. The project also offers a beta desktop app for macOS, Windows, and Linux, so users can choose a CLI or desktop workflow.

Cline works as a VS Code extension, terminal assistant, or SDK, allowing an agent to create files, run shell commands, browse the web, and call tools with human approval. Project rules and skills carry across its clients, while the SDK can register custom tools, lifecycle hooks, plugins, or MCP servers. It therefore spans personal coding assistance as well as custom agents and scheduled or embedded automation.

Open Interpreter is a Rust terminal coding agent designed for lower-cost and open models such as DeepSeek, Kimi, Qwen, and GLM. Its TUI can switch models and agent harnesses, execute commands inside native sandboxes, and use a built-in QA skill to operate and test web or native applications. Configuration and session state remain on the local machine.

Aider pairs a language model with an existing Git repository, building a map of the codebase so it can make coordinated changes across larger projects. It automatically records edits in Git and can run linters and tests after changes, fixing issues they expose. It supports many hosted models as well as local ones, and can take context from IDE comments, images, web pages, or voice.
