Tools

Debugging tools for every service on the platform, free and without an account. Each answers one question you would otherwise open a terminal for, and shows what the internet sees rather than what your own machine does.

Domains & DNS

What the world sees when it looks up your names.

DNS lookup

Query A, AAAA, CNAME, MX, TXT, NS, SOA, SRV, CAA and PTR records for any name.

WHOIS / RDAP

Registrar, status, registration and expiry dates, and name servers of a domain — .zm included.

Custom domain checker

Is your domain pointed at the platform correctly? Checks the CNAME and addresses the way the platform does.

App Platform

Is the URL answering, and with what?

HTTP & TLS inspector

Fetch a URL from the platform: status, redirect chain, response headers, timing and the TLS certificate.

Virtual Machines

Reachability of your machines from outside.

Port reachability

Does a port on one of your public addresses answer from the internet? Sign in required.

My IP address

The address your traffic arrives from — what to put in a firewall or database allow-list.

Object Storage

Make sense of S3 links and errors.

Pre-signed URL inspector

Decode an S3 pre-signed link: bucket, key, who signed it, when it expires and whether it already has.

Databases

Check a connection string before you use it.

Connection string inspector

Break a database URL into its parts, mask the password and spot a missing TLS setting.
