About Serial Console
Serial Console is a free, local-only serial terminal that runs in your browser. Plug in a USB-serial or console cable and configure a switch, router, or microcontroller with no install. Structured command blocks, a cross-vendor command library, hex view, and session recording — all running on your device, nothing uploaded.
What it does
- Works in the browser — no PuTTY, minicom, or driver install
- Desktop (Web Serial) and Android (WebUSB) with built-in CH340/CP210x/FTDI/PL2303 drivers
- Structured command blocks: copy, re-send, bookmark, share any command + its output
- Cross-vendor command library with fuzzy search (Cisco, Juniper, Arista, MikroTik, and more)
- Hex/ASCII view, live filter, session recording and export
- Local-only — open DevTools and watch nothing leave your machine
How to use Serial Console
Connect
Plug in your USB-serial or console cable and click Connect. Pick the port (desktop) or device (Android) from the browser prompt.
Set the baud rate
Choose a baud preset (115200 is common) or let auto-baud detect it. Set data bits, parity, and stop bits if needed.
Type or tap commands
Use the terminal directly, or search the command library and tap a command to send it. On a phone, use the macro buttons and quick-keys.
Record and export
Record the session and export it as a log or JSON file. Bookmark important command blocks for later.
Frequently asked questions
Does this work on iPhone or iPad?
No. iOS browsers use WebKit, which does not support Web Serial, WebUSB, or Web Bluetooth, so no browser on iOS can reach serial hardware. Use an Android phone with Chrome, or Chrome, Edge, Opera, or Firefox on a desktop. For iOS you need a native app and an MFi or Bluetooth console adapter.
Which browsers are supported?
On desktop: Chrome, Edge, Opera, and Firefox 151 or later, all through Web Serial. The first time a site asks for a port, Firefox asks you to allow serial access for that site, then shows the port picker. On Android, use Chrome. Safari, Firefox for Android, and every browser on iPhone or iPad cannot reach serial hardware.
Does my data leave my device?
No. The serial bytes go straight from the cable to the browser tab over the native Web Serial or WebUSB API. There is no server and no relay. Open DevTools and watch the Network tab stay empty.
What cables work?
Any USB-serial or USB-to-RJ45 console cable using a CH340/CH341, CP210x (Silicon Labs), FTDI, or PL2303 chipset. On desktop, any cable the OS exposes as a serial port works.
