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.
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.
| Tool | Type | Cost | Best 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 |
Paid products whose free tiers are enough to learn on — and in some cases enough to ship your first projects.
| Tool | Type | Free tier | Best for |
|---|---|---|---|
| Cursor | AI editor | Free Hobby tier (~2,000 completions + limited premium requests) | Developers and serious hobbyists who want an AI-native editor |
| Lovable | App builder | Free tier: 5 credits/day (max 30/mo), public projects | Non-technical founders shipping a web app or MVP fast |
| Replit | App builder | Free starter tier | Going from idea to deployed full-stack app with zero local setup |
| Bolt.new | App builder | Free tier: 1M tokens/mo, 150K/day cap (cut from 200K in Feb 2026) | Polished web prototypes, landing pages, and marketing-site demos in minutes |
| Windsurf | AI editor | Generous free tier — unlimited Tab completions plus Cascade agent access | Developers who want a strong free tier, and agent-mode users; no longer the budget pick after the 2026 price rise |
| GitHub Copilot | Assistant | Free tier: ~2,000 completions + 50 premium requests/mo | Developers already living in VS Code and GitHub; teams |
| v0 | App builder | Free tier with monthly credits | Frontend components and UI generation; Next.js projects |
| ChatGPT / Codex | Coding agent | Limited Codex access now included on the free ChatGPT tier | People already paying for ChatGPT who want delegated coding tasks |
| Base44 | App builder | Free tier with message limits | Internal tools and CRUD apps without touching infrastructure |
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.
