Hacker News Scraper with Telegram Alerts

A Python-based tool that monitors the Hacker News homepage for a specific search string (in titles and comments) and sends alerts to a Telegram chat when matches are found. The tool uses SQLite to store previous matches, so no duplicate alerts are sent. It runs periodically and can be deployed in a Docker container.

  • Telegram Bot Token (see BotFather)
  • requests and python-telegram-bot Python packages
