Does the extension replace the Telegram bot?

No. The Telegram bot remains available. The Chrome and Firefox extensions are additional browser dashboards that use the same backend and Linux agent.

Do I need to install the Linux agent first?

Yes. First install the Linux agent on your server with the PAIRING_TOKEN, then connect the extension using the same PAIRING_TOKEN.

Does the extension use SSH?

No. The extension never connects to your server over SSH. It only talks to server.howprog.one API over HTTPS.

Chrome extension

Download

Download the Chrome developer build

Use the ZIP build until a Chrome Web Store listing is published. Do not use fake store links; the developer build is the current install method.

Install

Install in Chrome with Load unpacked

Open chrome://extensions.
Enable Developer mode.
Extract the ZIP or use the browser-extension folder.
Click Load unpacked.
Select the extension folder.
Open the extension popup and enter the API URL plus the same PAIRING_TOKEN.

Agent first

Set up the Linux agent before connecting Chrome

The Chrome extension is not the installer. First run the agent install command on the Linux server. After the agent registers, use the same token in the Chrome popup.

curl -fsSL https://server.howprog.one/agent/install.sh -o install.sh
sudo bash install.sh --api https://server.howprog.one --pair PAIRING_TOKEN

Metrics

What Chrome shows

Server online/offline state.
CPU, RAM, disk, inodes and load average.
Uptime, last heartbeat and OS details when available.
SSL certificate days left when reported by the agent.
Active alerts and highest alert level.

Security

Why Chrome does not need SSH

The extension never connects to your Linux server. It only calls the backend API over HTTPS with X-Pairing-Token. The backend checks pairing ownership before returning server data.
