Comparison
Best AI coding assistants
A rare category where we have no skin in the game: none of these tools pay a referral commission, so what follows is straight recommendation, and the open options are genuinely the ones we reach for.
Worth stating plainly up front: not one commercial AI coding tool here runs a cash affiliate program. Cursor, Copilot, Windsurf, and Replit pay usage credits or gift cards at most, so nothing on this page earns the site money. That frees the comparison to be about the work. For most developers the honest answer is an open, bring-your-own-model agent, Cline above all, which gives you Cursor-style capability without sending your codebase or your bill to a vendor. See our affiliate disclosure for how the rest of the site works.

| GitHub Copilot The default AI pair-programmer, wired into GitHub. | Commercial | Free tier for some users; paid from ~$10/mo. No affiliate program. | Read review → | |

One caution that applies to every tool here: an AI agent will confidently write code that looks right and is wrong. Review its edits, and prefer tools like Aider that turn each change into a commit you can read and revert.
