webchanges 3.37.0

Web Changes Delivered. AI-Summarized. Totally Anonymous.

webchanges anonymously checks web content (including images) and commands for changes, delivering instant notifications and AI-powered summaries to your favorite platform.

Highlights

• AI-powered change summaries via Gemini (ai_google differ, BETA).

• Structural diffs for JSON and XML via the deepdiff differ.

• Visual diffs for images via the image differ (BETA).

• Bypass TLS/JA3 fingerprinting with the optional curl_cffi HTTP client.

• JSON-Schema-validated jobs.yaml and config.yaml for editor autocompletion and inline validation.

Requirements

webchanges requires . For the best experience, use the current version of Python; older Python versions are supported for 3 years after they’re replaced. Free-threaded Python is supported, though some optional dependencies may not be.

For Generative AI summaries (BETA), you need a free API Key from Google Cloud AI Studio (see here).
