AI Analysis

●MidShip ItDark Horse

Another HN job analyzer, but LLM classification runs at $0.07 per month.

Strengths

•Automated pipeline costs under $2 per year using Gemini Flash via OpenRouter
•Fully open source with separate repos for data pipeline and static site
•No server or database, GitHub Actions and Pages handle everything

Weaknesses

•HN job trend analysis is a crowded category with many existing tools
•LLM classification adds marginal value over keyword-based approaches

Post Description

I built a pipeline that fetches all HN job postings (both the monthly "Who is Hiring?" threads and direct job posts (/jobs)) classifies each one using an LLM (Gemini Flash via OpenRouter), and publishes the results as a static site.

What it tracks: - Top technologies and roles with month-over-month changes - Remote work breakdown (fully remote, hybrid, onsite) - Salary and equity mention rates - Experience level distribution - Per-job classification (click a technology to see its role breakdown, or vice versa)

Jobs are sent to the LLM in batches of 10 with structured output (JSON Schema). Total cost: ~$0.07/run, under $2/year. The pipeline writes JSON to a GitHub repo served via Pages. The site is a static Next.js export that fetches the JSON at build time. No server, no database, no ongoing costs beyond GitHub Actions minutes (free tier).

Everything is open source: - Data pipeline: https://github.com/gantryops/hn-jobs-data - Site: https://github.com/gantryops/hn-jobs-site

AI agents can consume the data directly there's an llms.txt at https://hn-job-trends.gantryops.dev/llms.txt with all the JSON endpoints and schemas.
