AI Coding Tools: Editors, Agents and Code Review Compared

ByAI Tools Directory Team

AI coding tools have split into several kinds: editors with AI built in, agents that take on whole tasks, terminal tools, code reviewers and app builders that need no coding at all. This guide groups 17 tools from our AI Coding Assistants and AI App & Website Builders categories by how they work. Every detail comes from the tool’s official website.

  • You prefer open source or local models: Cline and Aider let you choose your model.
  • Your team reviews a lot of pull requests: CodeRabbit and Qodo focus on code review.
  • You do not code: app builders like Lovable and Bolt.new create apps from a description.

Frequently asked questions

Which AI coding tools are free?

Cline, Aider and Zed are listed as free, according to their official websites. Cursor, GitHub Copilot, Warp and Qodo have free plans with paid upgrades.

What is the difference between an AI code editor and a coding agent?

An AI code editor is a full editor with AI features such as completions and chat. A coding agent takes a task, reads your codebase, edits files and runs commands with less step-by-step guidance. Many editors now include agents too.

Can I build an app with AI without coding?

Yes. App builders such as Lovable, Bolt.new, v0 and Replit create web apps from a text description, and include hosting so you can publish the result.
