WebMonitor

Watch prices, stock, announcements and deadlines. Fill in each check in a visual dashboard, or describe what you want in one sentence; when the page changes, you get an email.

Projects

Two ways to start

The same job — watching a page for you — with two entry points: a dashboard you fill in, and an assistant you describe it to.

WebMonitor

Visual dashboard

Select the part of the page you actually care about with XPath, choose how often to check it, and get an email when the text changes. Tasks, run logs, public subscriptions and mail settings all live in one interface; no model service is needed.

XPath region monitoring · Email alerts · Public tasks and subscriptions · CC BY-NC 4.0

WebMonitor-Agent

Conversational monitoring

Paste a link and say what to watch, how often to check, and when to notify you. The assistant opens the page for a real sample first; review the content and recipients, then create the monitor. Price thresholds, restocks and new list entries are handled by condition rules.

Where to go next

The demo, the setup guide and the source.

Live demo

A separate demo instance run by the maintainer; it may be unavailable.

Setup and configuration guide

From preparing Docker to your first alert: install, email, task management, troubleshooting and data retention.

WebMonitor guide

Download Compose, create .env, start it, and create your first monitoring task.

Agent guide

Download the deployment files, configure a model service, and create your first monitor by chat.

GitHub organization

Source code, release notes and issue tracking.

Get Started

Three steps

Prepare Docker, download the deployment files, create .env from the template, then run the same startup command. A normal install needs no repository clone and no registry login.

WebMonitor-Agent

mkdir -p webmonitor-agent && cd webmonitor-agent
# Download the deployment files and create .env from /en/docs/#agent
docker compose up -d --wait

Open http://localhost:8080 and sign in with the admin email and password from .env; if no admin exists yet, create one as described in the docs. The first start also builds two helper images locally, which takes a few minutes.

WebMonitor

mkdir -p webmonitor && cd webmonitor
curl -fsSLo compose.yaml https://raw.githubusercontent.com/webmonitor/WebMonitor/main/compose.yaml
# Create .env from the template at /en/docs/#webmonitor
docker compose up -d --wait

Open http://localhost:8000 and sign in with the username and password from .env; configure email in the app.

Both projects start with the same command in their own deployment directory and pull the public latest image. Agent keeps its database and page archives in temporary storage, so stopping or recreating the data containers loses data; set up persistent storage and backups before long-term use.
