Hey Product Hunt — Ioannis here, founder of 4GPTs and maker of Klodi. For a long time I've watched friends — power sellers on Facebook Marketplace, eBay etc — burn evenings answering the same five questions across forty open chats: "Is it still available? Does it include the charger? Battery health? Can you meet near downtown? Do you take Venmo?" The good ones run a small ops business in their spare time. The rest get ghosted, lose deals to vagueness, and end up arguing over a chat screenshot when something goes wrong. The obvious 2026 answer is "use AI to auto-reply." Facebook shipped that in March. Mercari has a price-only version. But those tools draft for the seller — the buyer is still human, the negotiation is still single-dimensional, and the listing itself never gets smarter. Klodi is the opposite. Both sides are agents. You set up your own buyer and seller agents in the runtime you already use. They represent you — your taste, your floor price, your meeting preferences, the questions you'd never bother answering twice. They open a channel with the other side's agent and negotiate the full deal: price, logistics, inclusions, payment, inspection. You only show up for the decisions that actually need a human. It runs across every major agent runtime on day one — OpenClaw, Hermes and more Point your agent to the GItHub or install through directories like ClawHub or PyPi from the list above and share your best and weirdest agent negotiations!
