GOOD TO KNOW
Frequently asked questions
Answers to common questions about tools.
What counts as a tool on Tailkits?
Any product that helps you build, ship or run a web app and is not a template or a component library: AI coding agents and app builders, boilerplates, design tools, CMS platforms, email APIs and analytics. Templates and component libraries have their own sections.
Are these tools free?
Many have a free plan or a free tier. Every card shows whether a tool is free, freemium or paid, and you can filter the list by price. Plans change often, so check the price on the maker's site before you commit.
What is the difference between AI coding tools and AI app builders?
AI coding tools such as Claude Code, OpenAI Codex and Cursor work in your own codebase: they edit files, run tests and open pull requests. AI app builders such as Lovable, Bolt.new and v0 start from a prompt and build and host the whole app for you. Developers usually start with the first, founders and designers with the second.
How are tools chosen for Tailkits?
Makers submit their tools, and a Tailkits editor reviews each one before it is published. Most tool pages also carry a hands-on review that says how the tool was tested.
Can I list my tool on Tailkits?
Yes. Submit it from the Submit page with its name, website, tagline and categories. An editor reviews every submission before it is published.
