Dig — DNS lookup

Like Google Admin Toolbox Dig, powered by the same Google Public DNS. An IP address does a reverse (PTR) lookup.

Base64 encoder / decoder

UTF-8 safe, with URL-safe mode. Paste Base64 and it decodes; paste text and it encodes. You can also drop in a file.

Cron expression parser

Explains a crontab schedule in plain words and shows the next runs in your time zone. Five fields, an optional seconds field, names (MON, JAN) and macros like @daily.

Certificate decoder

Paste a PEM certificate (or a whole chain) or drop a .pem / .crt / .cer file: subject, issuer, validity, SANs, key, fingerprints. Get one with openssl s_client -connect example.com:443 -showcerts.

YAML linter & validator

Checks syntax as you type, points to the exact line, and warns about classic traps: tabs, duplicate keys, trailing spaces, and yes / no / on / off that YAML 1.1 tools (Ansible, older Kubernetes) read as booleans. Paste YAML or drop a .yml file.

Google Admin Toolbox:

Google's own free web tools for admins. They open on toolbox.googleapps.com.
