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

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
• ●80.9% SWE-bench Verified: highest autonomous coding benchmark score

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

Ollama

Run AI models locally with Docker-like simplicity, 200+ model families, and full API compatibility

Ollama is the open-source standard for running AI models locally. With 155K+ GitHub stars and 2.5M weekly downloads, it provides Docker-like commands (pull, run, create) to manage 200+ model families on your own hardware. Ollama offers full OpenAI and Anthropic API compatibility as a drop-in replacement, GPU acceleration across Apple Metal, NVIDIA CUDA, AMD ROCm, and Vulkan, plus features like vision support, structured JSON outputs, tool calling, embeddings, and experimental image generation. Ollama Turbo ($20/month) adds optional cloud inference for users who want both local and hosted options.

• ●200+ model families: Qwen2.5-Coder, DeepSeek-Coder V2, Codestral, Qwen3-Coder, GPT-OSS, Llama 4, and more
• ●Docker-like CLI: ollama pull, ollama run, ollama create with Modelfile customization
• ●OpenAI and Anthropic API compatibility as a drop-in endpoint replacement

OpenAI Codex

✓

Cloud coding agent with GPT-5.5 frontier model, 1M+ developers, Desktop App, in-app browser use, and parallel sandboxed environments

OpenAI Codex is a cloud-based software engineering agent platform used by over 1M developers. Launched in May 2025 with a Desktop App added in February 2026, Codex spins up parallel sandboxed environments, reads your codebase, writes code, runs tests, and submits PRs autonomously. As of April 2026, GPT-5.5 — OpenAI's newest frontier model — is available in Codex and recommended for most tasks including complex coding, refactors, debugging, testing, validation, and knowledge-work artifacts. The Codex app added in-app browser use for local development servers and file-backed pages (visual bug reproduction and fix verification) and automatic approval reviews via a reviewer agent. Codex CLI 0.124.0/0.125.0 added quick reasoning controls, reasoning-token usage in `codex exec --json`, and Fast service tier defaults for eligible ChatGPT plans. The platform also includes a macOS Desktop App with Xcode integration for Apple developers.

• ●GPT-5.5 (April 2026): newest frontier model, recommended default in Codex for complex coding, refactors, debugging, testing, validation, and knowledge-work artifacts
• ●1M+ developers using Codex for software engineering
• ●Parallel sandboxed environments: reads codebase, writes code, runs tests, submits PRs

OpenCode

Open-source AI coding agent for the terminal with multi-provider support

OpenCode is an open-source AI coding agent built for the terminal. It helps developers write code via a terminal interface, desktop app, or IDE extension. OpenCode supports many LLM providers including Claude, GPT, Gemini, and local models, with GitHub Copilot and ChatGPT Plus login options. It features LSP integration, multi-session agents, and a privacy-first approach that does not store code or context. The CLI supports run commands for single tasks, a headless API server, and MCP management.

• ●Terminal interface and desktop app (beta)
• ●opencode run for single-task execution
• ●opencode serve for headless API
