Reach the home lab
Leave a development board or instrument connected and continue the work from another location.
NullPort for individuals
Your hardware stays put. Your work does not.
Reach your own bench, continue a project from another computer, or help someone with their equipment—using one focused invitation for the exact thing you want to share.
Made for practical moments
Use the hardware you already own from wherever the work takes you
Support a device remotely
Guide a trusted person beside the equipment while you use the exact screen, port, or device required.
Keep a long test moving
Check a screen, collect logs, replace a file, or reconnect after a short network interruption.
Work across your computers
Use Windows, Linux, macOS, Android, and Raspberry Pi where the selected capability is supported.
Everything in one application
Choose only the capability the task needs
A screen session does not automatically expose files. A file invitation does not automatically expose a USB device. You decide each boundary.
Remote USB hardware
Use supported debug probes, storage, cameras, audio devices, security keys, printers, phones, and specialist equipment from another computer.
Serial ports and boards
Reach RS-232, RS-485, UART and USB-to-serial equipment, including the signals many flashing tools use.
Screen help without over-sharing
Let someone watch, grant interactive control only when needed, and stop control immediately from the host.
Files, folders and logs
Move firmware, captures, project folders and large files with pause, resume, retry, integrity checks, and history.
A private work network
Bring remote computers and network equipment into one private workspace without changing home or office router settings.
Chat, voice and video
Keep conversation beside the work and add a call when explaining the equipment is faster than typing.
You remain in control
Private by intent, visible while active
Each invitation is a private, one-use 12-character code for a chosen capability. The host sees active participants and can withdraw control, remove a guest, or stop the session.
