Port Lookup

Search by port number or service name (try 443 or "database"). Runs entirely in your browser — the full list is embedded on the page.

ℹ️ About this list

Covers the well-known/registered ports someone doing DevOps or networking work actually runs into — not exhaustive (there are 65,535 possible ports).
Search matches the port number, service name, protocol, and description, so typing "database" surfaces MySQL, PostgreSQL, MongoDB, Redis, and more.
Runs entirely client-side — nothing you type here is ever sent anywhere.

💻 Show API usage examples (cURL)

Look up a single port:

curl -sS https://devops.majbase.com/port-lookup/api/443

Returns a JSON array (a port can have more than one entry, e.g. TCP and UDP variants): [{"port": 443, "protocol": "TCP", "name": "HTTPS", "description": "..."}], or a 404 with {"error": "..."} if the port isn't in this tool's list.

List every port, or filter by keyword:

curl -sS https://devops.majbase.com/port-lookup/api
curl -sS "https://devops.majbase.com/port-lookup/api?q=database"

Returns a JSON array of matching entries in the same shape as above.
