What it does
Hexpit puts the small utilities you reach for during a debugging session on your phone: decode a JWT or a certificate, read a DER structure, build a cron expression, convert and format JSON, YAML, XML and SQL, calculate subnets, look up DNS records, probe a TLS handshake, check a port, or decode the smart card and SIM data that other tools hide.
The tools run on the device. Options and saved profiles stay on the phone, encrypted. Hexpit needs Android 13 or newer.
The 11 network tools connect only when you run them, and only to the host you enter (a few, such as My IP, contact a fixed public service when you tap their button). Use them only on systems you own or are allowed to test.
Three promises
Local-first
No backend of ours. Tools work on the data you give them, on your phone.
No account, no tracking
No sign-in, analytics, crash reporting or ads. What that means, and how to check it.
