SwapDeck is a local item-swapping app that helps you turn things you no longer need into things you actually want — without buying or selling. Add your items, swipe through nearby listings, match with other traders, and build fair item-for-item deals using smart matching, AI valuations, and a Fairness Meter. No coins. No marketplace payments. Just swipe, match, and swap.

RankReason is a product research and ranking platform that helps people make better buying decisions without digging through endless reviews and marketing claims. It analyzes product specs, manuals, expert reviews, and real owner feedback, then turns that research into clear rankings, practical recommendations, and plain-English tradeoffs. RankReason is also built for AI agents, with structured Markdown, llms.txt, and dedicated agent-friendly data for product research and comparison tasks.

ToolVitals is a public software intelligence platform that tracks the health of thousands of developer tools and open-source projects. It monitors signals like maintenance activity, release velocity, licensing and openness, source coverage, and evidence confidence — helping you quickly see which tools are actively maintained, which are slipping, and which are worth betting your stack on. Tool profiles are also available in Markdown and JSON, making the data useful for both humans and AI agents.
