- It runs on your own computer or server; there is no hosted crawler, and emailed reports need your own SMTP server.
- The AI assistant uses your own API key or local model, so any LLM charges come from that provider.
- Pages built by JavaScript are crawled only in the optional browser mode, which renders them in Chromium.
