It brings useful tools and resources together in one place, helping you save time, discover better resources, and bookmark your favorites for free, without signing up.

    About Web Tools Finder

  • Yes, it is free. Browsing, searching and saving tools need no account. Your saved tools are kept in your browser on this device, so they are not shared between devices.

    Open your saved tools

  • You can discover AI tools, development resources, UI/UX design tools, graphics, website inspiration, open-source projects, learning materials, freelance resources, and more. We're also expanding into useful communities and groups to help you connect, learn, and grow.

    Browse the directory

  • Use the Search Directory, or press Ctrl K (Cmd K on a Mac) to search from any page. Each section lists its tools by category, and when tools have pricing details you can filter by price, such as Free, Freemium or Paid. Open a tool to read its description, highlights and details, and save the ones you like.
