Frequently Asked Questions

Quick answers about the directory, listings and your privacy.

  • Web Tools Finder (WTF) is a curated directory built by developers and designers for web developers, designers, vibe coders, and freelancers. 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.

    Search the directory

    See the AI prices

  • Featured spots can be arranged on the Home page, in each section and on the Agencies and Deals pages. Get in touch through the contact page and tell us what you would like to promote. Featured and sponsored placements are always labelled.
