Free web tools: check whether a link is safe before you click, look up who owns a domain and how its DNS is set up, test your connection speed, and check a site's speed, HTTPS and accessibility. Webcentive's own tools: traceroute, web environment and DNS tools are under More on webcentive.

Each site has quick lookups: who owns it (whois), its history (Wayback Machine), a safety check, and one-tap questions to AI helpers. Grok asks you to tap Send first.
