Gollum
LiveAuction tracker with automated alerting
overview
Gollum is an auction tracker that answers a very specific question: which listing is the best quality for the price, rather than simply the cheapest? It was born from a real quest — finding the right necklace without overpaying.
A Playwright scraping pipeline follows auctions over time and ranks items on a quality-for-price basis. When something worth acting on appears, it fires an alert through a self-hosted email service, so the whole loop runs without third-party notification providers.
On demand, an LLM vision model reads the listing photographs to pull details that never make it into the structured text — condition, materials, hallmarks — and feeds them back into the ranking.
how it works
- Ranks on quality-for-price instead of lowest price, so genuine bargains beat noise.
- Playwright pipeline tracks listings over time rather than taking a single snapshot.
- Alerts go out through a self-hosted mail server — no external notification SaaS.
- On-demand LLM vision reads listing photos to enrich the ranking signal.
