5+ Free AI Development Platforms

Six tools here have a free plan: Replit, Hugging Face, v0, Google AI Studio, Firebase Studio, and bolt.new. The limits vary. v0 caps free users at 7 messages per day and $5 in monthly credits. Firebase Studio is in preview with a limited number of free workspaces. Hugging Face is free at the base level but some advanced features require the $9 a month PRO account. bolt.new also offers a Pro plan at $29 a month for users who need more than the free tier allows.

Replit, v0, and bolt.new all let you describe what you want in plain language and generate a working app from that description. Replit includes a built-in database and sign-in system so the full app runs without extra setup. bolt.new also accepts imports from Figma and GitHub if you already have designs or existing code. All three have free plans, though v0 limits free users to 7 messages per day.

Pythagora connects directly to VS Code and Cursor, so it works inside the editor you already use. It handles front-end building, back-end debugging, and one-click deployment from there. The trade-off is that it only supports React projects for now, and it is the only paid-only tool here, starting at $49 a month.

Replit, Hugging Face, v0, and Firebase Studio all support Web Application Deployment. Hugging Face offers managed hosting with flexible hardware options. Firebase Studio covers end-to-end testing and deployment in one place, though it is still in preview. v0 takes an app from a text prompt through to a production-ready build. Replit includes built-in backend services that stay live after you deploy.

Google AI Studio is built specifically for trying out prompts and AI models quickly. It gives access to Google's Gemini models, supports text, images, and other input types, and lets you test structured outputs and function calls in an interactive environment. It has no published pricing on its main site beyond a contact sales option, so the cost for larger use is not clear upfront.

Yes. Pythagora currently works only with React on the front end and a JavaScript back-end runtime. The company states that Python support is coming later. Every other tool here is more general in the stacks it accepts. That limit matters if your project uses a different framework, since Pythagora is also the only paid-only option, starting at $49 a month.
