Kit – open-source toolkit for building AI devtools

In plain words

Kit is an open-source toolkit designed for developers building AI-powered development tools. It provides reusable components and frameworks to streamline the creation of AI devtools, reducing the time needed to integrate AI capabilities into development workflows. The toolkit is aimed at developers and tool builders who want to leverage AI in their products without building infrastructure from scratch. Kit's open-source nature allows for community contributions and transparency in how AI devtools are constructed.

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
