Open-source terminal pair programmer with git-native workflows

Aider is an open-source AI pair programming tool that runs in the terminal and keeps your workflow inside git. It can automatically create commits, apply diff-based edits across multiple files, and map your repository for large projects. Aider is model-flexible: you can use current OpenAI, Anthropic, Google, DeepSeek, and local model stacks through direct APIs, OpenRouter, Ollama, or compatible endpoints.

• ●Automatic git commits with descriptive messages
• ●Diff-based, multi-file editing directly in the terminal
• ●Works with current frontier model families (OpenAI, Anthropic, Gemini) plus DeepSeek and local models

Claude Code

✓

Anthropic's terminal-based AI coding agent with Claude Opus 4.7, /ultrareview, Routines, /ultraplan, and 80.9% SWE-bench

Claude Code is Anthropic's terminal-first coding agent (GA since May 2025) that lives in your terminal and handles full development workflows. As of Week 16 (April 2026, v2.1.105–v2.1.113), Claude Opus 4.7 is the default model on Max and Team Premium with a new 'xhigh' effort level (recommended for most coding work) selectable via an interactive /effort slider. Recent shipments include /ultrareview for parallel multi-agent code review in the cloud (public research preview from Week 17, v2.1.119), Routines on Claude Code on the web for templated cloud agents triggered by schedule, GitHub events, or API, /usage breakdown showing what is driving your limits, native per-platform CLI binaries replacing bundled JavaScript, /ultraplan (Week 15) for cloud plan mode from the terminal, the Monitor tool for streaming background events, /autofix-pr to enable PR auto-fix from the CLI, /team-onboarding for replayable teammate ramp-up guides, and session recap (/recap) showing what happened in unfocused terminals. Custom themes can be built from /theme or shipped via plugins. Agent Teams enable multiple Claude Code instances to collaborate on complex tasks. Integrates with VS Code and JetBrains IDEs and supports GitHub Actions for automated code review, issue resolution, and PR creation.

• ●Terminal-based AI agent (GA since May 2025) for full development workflows
• ●Claude Opus 4.7 default on Max and Team Premium (Week 16, April 2026) with new 'xhigh' effort level and interactive /effort slider

Goose

Open-source terminal-first AI agent from Block for autonomous coding

Goose is an open-source AI agent from Block that works as a terminal-first coding assistant. Rather than autocomplete, it executes tasks autonomously in your terminal: running commands, editing files, making multi-file changes, reading error logs, and self-correcting when commands fail. Goose supports multiple providers including OpenAI, Anthropic, Google, Meta, and Ollama, and integrates with Claude Code or Google Gemini CLI subscriptions. It includes MCP support for tools, APIs, databases, and browser automation, with session management for conversation context and state.

• ●Terminal-first: executes commands, edits files, runs tests
• ●Self-corrects when commands fail
• ●Multi-file editing and git commands
