Nokwatch is a lightweight Python-based website monitoring tool that runs on low-resource devices like a Raspberry Pi. It monitors multiple websites for content changes and notifies you by email, Discord, or Slack when your criteria are met.

Can Nokwatch run on a Raspberry Pi?

Yes. Nokwatch is designed for Raspberry Pi and similar low-resource devices. Use the minimal requirements install (requirements-minimal.txt) for a smaller footprint without AI or screenshot features.

How does Nokwatch notify me?

Nokwatch can send notifications via email (SMTP), Discord webhooks, and Slack webhooks. You can use multiple channels per monitor and set a cooldown to avoid spam.

What can Nokwatch monitor?

Nokwatch monitors web pages for content changes using string or regex matching. It also supports JSON/API monitoring with JSONPath, HTTP status and response time alerts, and optional AI-based content change detection. Plugins like nokwatch-scan (Scanner) add listing-page monitoring for new items.

Can I extend Nokwatch with plugins?

Yes. Nokwatch supports optional plugins that add new job types and UI. Install plugins from the Modules page in the Web UI or via pip (e.g. pip install nokwatch-scan). Plugins share the same dashboard, notifications, and cooldowns.
