Paul Oh's profile on Product Hunt

About

I build practical tools for people who sell online — one person writing the code and answering the email. PriceProof (priceproof.app) — a small studio of Shopify apps that turn one compliance rule into one honest line on your storefront: EU Omnibus 30-day lowest price per member state, GPSR safety disclosures, EU textile labels, UK/AU/CA was-price substantiation, and Japan's dual-pricing rules. PackshotForge — a Photoshop script that rebuilds product-photo backgrounds with AI while keeping the product pixels and label text intact. web_harvester — a no-code scraper that watches a page and pings you only when something changes. Drawn to the unglamorous parts of ecommerce: rules you must follow, and work you repeat every week.

PriceProof - Free Shopify apps for EU & Japan pricing rules

Four free Shopify apps that handle the price/label rules small stores keep tripping on: EU "was-price" history for sale displays, GPSR product-safety info, EU textile fibre labels in the shopper's language, and Japan's dual-price (二重価格) record-keeping. Each app records or checks the data the rule expects and shows it on your storefront — install, pick your market, done. Built solo, all free, no upsells.

PackshotForge - Studio product photos, generated inside Photoshop

I built this because I was tired of choosing between expensive product photo shoots and monthly AI photo apps that charge per image. PackshotForge is a Photoshop script: open a raw phone photo, pick a scene, and Google's Gemini model rebuilds the background while keeping your product (shape, colors, label text) intact. It lands as a layer. It runs on your own free Gemini key, so no subscription. 21 presets, marketplace export sizes, batch mode. Happy to answer anything!

web_harvester - Scrapers stop after one grab. This one keeps watching.

Most scrapers extract once and quit. web_harvester is a no-code Chrome extension + Python CLI that keeps running on your schedule and tells you what changed. Pick a page, tick the fields (no code, it finds them), leave it on. It pings you only when something moves: price drop, back in stock, new listing, rank or review shift, via Slack, Discord, or email. Data lands in Sheets/CSV/Excel/SQL, stacked by date. Public data, your own session, robots respected, no CAPTCHA or proxy evasion.
