AI Coding Tools

The open-source terminal coding assistant where every edit is a git commit

Aider is best for developers who want open-source AI coding with a git-native workflow and full model flexibility — every edit is a commit, so git revert is your undo button. Supports 100+ LLMs via LiteLLM, including local models through Ollama for offline or privacy-sensitive work. Architect mode lets Claude Opus 4 plan while GPT-4o-mini implements, cutting cost 10x. No GUI, no subscription, no seat fee — you pay only your API provider.

The terminal-native agentic coding CLI from Anthropic

Claude Code is best for developers who live in the terminal and want a fully agentic coding loop — it reads files, runs shell commands, edits code, commits to git, and chains multi-step tasks autonomously. You pay only for API tokens consumed, typically $2-8/day for active use on Sonnet 4. There is no GUI: no file tree, no inline completions, no diff view.

Sourcegraph's AI coding assistant with full-repo context and enterprise access controls

Cody is best for enterprise teams that need AI answers grounded in the full private codebase — it indexes every repo (not just open files) and uses Sourcegraph's code search engine for precise navigation. Pro is $9/mo, cheaper than Copilot or Cursor. Enterprise plans add SAML SSO, audit logs, and air-gapped deployment. The trade-off: setup is more involved (Sourcegraph account + IDE extension + optional self-hosted instance), and agentic capabilities lag Cursor Composer and Claude Code.

The AI-native VS Code fork for multi-file editing and autonomous coding

Cursor is best for developers who want an AI-first IDE without learning a new interface — it forks VS Code so extensions, keybindings, and themes work unchanged. The $20/mo Pro plan includes 500 fast premium requests (Claude Sonnet 4, GPT-4o, Gemini 2.0 Pro) and unlimited slow requests. Composer handles multi-file feature work; Background Agents run long tasks async. Hobby plan gets 2000 completions and 50 slow premium requests per month at no cost.

GitHub's AI pair programmer embedded in VS Code, JetBrains, and the web editor

GitHub Copilot is best for developers who want AI across the widest possible set of editors and the tightest GitHub integration — VS Code, JetBrains IDEs, vim, Neovim, Xcode, and the github.com web editor all work. Individual Pro is $10/mo, half the price of Cursor Pro. The trade-off: agent mode is less capable than Cursor Composer or Claude Code, and there is no persistent project memory beyond basic repository context.

The AI IDE with Cascade flow-based agent mode and persistent memory

Windsurf is best for developers who want Cursor-class multi-file agent editing at $5/mo less — Pro is $15/mo vs $20 for Cursor Pro. Cascade is Windsurf's flow-based agent that plans steps, edits files, runs commands, and persists Memories across sessions so project context survives restarts. The free tier's 5 Cascade flows per month makes serious evaluation hard — Pro is effectively required for real use.
