I Built a 500k-Domain Search Engine for Makers in a Weekend for $10

At 2am, annoyed by SEO sludge, I built a personal search engine for makers. Over a weekend, I crawled and summarized 560,000 homepages using a rented GPU and a local LLM, costing about $10. The system includes a fetcher, a worker that summarizes pages, a steward that blocks spam domains, and a search UI. Key challenges: 90% of the web is corporate, Tumblr and Neocities flooding, and GPU rental pitfalls. The final index is under 1GB, and the approach can scale to millions of sites for ~$100.

The headline, if you only read one paragraph: for about $10, an overnight GPU rental, and a few hours of steering the thing while it ran, you can have a personal search index of a few hundred thousand sites, under a gigabyte on disk.

    Here's my impressions of your algorithm:

    1. read each site

    2. rent a 4090 with https://vast.ai to run vllm

    3. let llm model invent its own category and tag names freely

    4. save 1KB of metadata each

    a. a small local language model that reads each one and writes a name, two or three sentences, a category, and a handful of tags.

    5. `code is going up as open source` soon (TM)

    FYI for those needing a list of domains

    Subject: I want all domains and subdomains

    Interesting project. Website discovery is indeed in a pretty dire spot, definitely a space that needs innovation. An auto-labeled website directory isn't that silly of an idea.

    I have a 400 GB sqlite database with samples of rendered root document DOMs I use for ad detection in Marginalia Search I've been meaning to explore similar ideas using.

    Reminds me that AltaVista's servers ran in 4G of RAM (there were famous, at the time, pics of the circuit boards - DEC was rightfully proud of this, 30 years ago) and that a modern AltaVista should run on a decent laptop :-)

More from this day
