Popular & useful tools

🔒

Browser-only tools can process files locally. Server tools use strict size limits and can be moved to object storage later.

⚡

Lazy-load heavy processing and keep the homepage lightweight so the toolbox stays responsive.

🤖

AI runs through your backend so secret API keys are never shipped to visitors.

AI POWERED

Connect your OpenAI key on the server and turn ToolHub into an AI utility platform.

FAQ

Are the tools free?

Browser tools in this starter are free. AI and server processing can be limited by plan.

Is my OpenAI key visible?

No. The included architecture keeps the OpenAI secret on the Node.js server.

Can I add more tools?

Yes. Add a card, a page/interface and a JavaScript function or backend endpoint.
