ZeroDaily is a high-performance, serverless, and automated cybersecurity newsletter platform that aggregates, summarizes, and broadcasts threat intelligence, CVEs, and security news.
The live platform is accessible at: zerodaily.in
Badge labels and colors can be customized with left_text, left_color, and
right_color, for example:

- Automated Intelligence Ingestion: Integrated parser utilities digest security feeds and employ Groq/OpenAI APIs to summarize technical CVEs into readable, engaging updates.
- Robust Double Opt-In Flow: Protects against spam using cryptographic verification tokens. Generates unique verification and unsubscribe tokens per subscriber, with email deliverability managed through the Resend API.
- Analytics & Engagement Telemetry: Custom JavaScript trackers log page-views and active reading session durations. The Flask endpoint logs session lengths and computes average read times to gauge content interest.
- Security Hardening:
- Configurations loaded safely via environment variables.
- Continuous Integration: Integrated GitHub Actions CI/CD pipeline automates syntax testing and verifies build dependencies on every push.
- Daily Hack Roasts: Features a witty daily summary of recent hacks. Long security stories are neatly collapsed by default to keep the reading experience focused.
- SEO-Engine Ready: Automatically updates an XML sitemap and a standard RSS feed dynamically. Includes a robots.txt configuration.
- Telemetry Dashboard: An internal interface to monitor total/recent subscribers, database metrics, and system health status.

The web interface is decoupled from the content ingestion engine. To learn more about how security news is scraped, summarized via LLMs, and compiled into JSON issues, visit the bot0 Scraper Repository.
