TPC Hosting free tools

TPC Hosting free tools give an AI assistant 44 read-only tools, the same ones offered at tpc-hosting.com/tools. No account or API key is needed. Network checks run from a server in Germany, so they test the real path instead of guessing: traceroute with every hop and round-trip time, DNS trace from the root servers down to the authoritative nameservers, a live HTTP/3 (QUIC) handshake, time to first byte split into DNS, connect, TLS and waiting, SSL/TLS handshakes with certificate chain, expiry and protocol versions, and SMTP tests of mail servers on port 25 with STARTTLS. The SMTP test never sends mail. More lookups: DNS records (dig, propagation, DNSSEC, reverse DNS), email authentication (SPF, DKIM, DMARC, BIMI, MX, blocklists and an overall deliverability report), website checks (redirect chains, response headers, is the site down, hosting provider, WHOIS over RDAP), robots.txt and sitemap validation, and IP and ASN lookups. Calculators, generators and decoders that make no network request: subnet, bandwidth, chmod, uptime and cron calculators; SPF, DMARC, robots.txt, .htaccess and llms.txt generators; email header, SSL certificate and CSR decoders. Private keys are refused. Every tool is read-only. Checks are rate limited per caller. Private and reserved addresses are refused, and there is no port scanner. Results are data returned by the checked servers, and each result links to the same check on tpc-hosting.com.
