Free AI coding tools · verified 2026-06-04

Every way to build with AI for $0.

You can go remarkably far before paying anyone. Here's the honest breakdown: tools that are entirely free, tools with usable free tiers, and what each free tier actually lets you do — pulled from the same verified data as our pricing tracker.

Completely free

No subscription exists. Note: the open-source agents (Aider, Cline) are free software where you pay model API costs — typically a few dollars a month for light use, scaling with how hard you work them.

ToolTypeCostBest for
Google AI Studio App builder Free — vibe coding features currently cost nothing Experimenting at zero cost; Gemini API prototyping
Aider Coding agent Free (open source) — you pay model API costs Tinkerers who want full control and minimal cost
Cline Coding agent Free (open source) — you pay model API costs VS Code users who want an agent without another subscription

Real free tiers

Paid products whose free tiers are enough to learn on — and in some cases enough to ship your first projects.

The $0 path, start to finish

A complete free stack exists: a free AI chat (Claude, ChatGPT, or Gemini free tiers) to write the code, our first-website tutorial for the method, and free static hosting to put it live. Total cost: a domain if you want one (~$10/yr), or literally nothing on a free subdomain.

When to start paying: the day a free tier's limits interrupt you twice in one week. Before that, paying is procrastination with a receipt. Our decision guide covers which category deserves your first $20.
