EventHunter
An open-source event discovery engine that scans 34+ sources, enriches them with a local LLM, and presents everything in a single interface — IT events and concerts.
Overview
Instead of checking dozens of sources one by one, it automatically scans 34+ sources for IT events and concerts worldwide, enriches them with AI, and presents them in one interface. The same engine can track any topic tomorrow.
All AI inference runs locally on a Mac Studio M4 Max via Ollama (qwen3:32b). Token cost is zero, scraped content never leaves the machine (KVKK/GDPR), and there are no rate limits.
Celery Beat + RedBeat kicks off a full crawl every Monday at 03:00 UTC. The schedule lives in Redis and can be changed at runtime. URL-based deduplication ensures the same event is never stored twice.
Features
Conferences, summits, webinars, workshops, hackathons — from platform giants to cybersecurity and analyst firms
City-based tour tracking, electronic music, nationwide ticket news · genre tagging
Two-stage architecture: intent resolution → real DB query · no hallucinations
Quality × 0.4 + match × 0.6 · scored against the user’s interests and city profile
Region, category, company, city, date range, online/in-person, content type + free-text
Playwright (headless Chromium) renders JS-heavy pages · httpx + feedparser for static sources
Architecture
Data flow: each source is scanned, HTML is cleaned, an LLM produces structured JSON via the LiteLLM proxy, results are deduplicated, written to PostgreSQL, and served in the React UI.
