Test if a specific TCP port is open and accepting connections on any host or IP address.

Ping a host to check if it is reachable and measure round-trip latency from our Indian data centre.

Trace the network path from our data centre to any host and see every router hop along the way.

Query DNS records for any domain — A, AAAA, CNAME, MX, NS, TXT, SOA, and more. See all DNS data at once.

Perform a reverse DNS (PTR) lookup to find the hostname associated with any IPv4 or IPv6 address.

Calculate network address, broadcast, usable IP range, subnet mask, and wildcard from any CIDR notation.

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes for any text input. All computation happens in your browser.

Generate cryptographically secure random passwords with customizable length and character sets. Nothing leaves your browser.

Encode text to Base64 or decode Base64 strings back to plain text. Supports full UTF-8. Runs in your browser.

Decode and inspect JWT tokens — view header, payload claims, timestamps, and signature. Nothing leaves your browser.
