Rescanner
Know if it's worth flipping before you buy
What it does
Hey Product Hunt! I built Rescanner after losing money on too many thrift store flips. I kept buying things that looked good but never sold, or sold for less than I paid. So I built a tool that pulls real eBay sold data and gives you a Flip Score before you buy. Type in "Nike Air Force 1" and get the avg sold price, sell-through rate, and your exact profit margin in seconds. Still in beta. First 25 hunters get 1 month free. Would love brutal feedback on the scoring algorithm.

- IMI made a price aggregator to find the best PC parts deals across eBay2025 · pcprice.watch · ▲20
Started PC flipping as a hobby (buying used parts, building PCs, and selling them for a small profit). Found that focusing on used parts on eBay gives the best margins - like finding a GPU 20% below market, pairing it with other deals, and selling the complete build locally. I discovered that eBay marketplaces (.com, .de, .co.uk etc.) often have different prices for the same items! Or just completely different items. So I built an eBay price scanner for PC components. It scans listings across different Ebay markets, calculates median prices, and flags anything selling below market (including…

- IBI built an interactive demo builder for your sales team2024 · demoshake.com · ▲8
Hey HN! I’ve created (co-created with my co-founder) a tool called demoshake that helps you build interactive demos and use them in your sales process. The idea is simple - you create as many demos as you want, group them and let your sales team use them in their demos calls. You can embed demos in your landing page (iframe style) too. I welcome any criticism and suggestions! Harun
- MAMe and my buddy made $20 with a Stripe link and a Tweet2023 · ▲7
Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
