- Worth noticing
- Leak watch searches public GitHub code about once a day, but cannot check private repos, git history, chats, or other sites.
Field notes
The setup flow asks users to connect a provider key, choose daily and monthly thresholds, and optionally enable alerts for spending spikes against a seven-day average. For leak watch, the site says it sends only a short key fragment to GitHub code search; it explicitly excludes private repositories, chat, and sites beyond indexed public GitHub code. The integrations and kill switch are both marked beta.
