Competitor monitoring for Shopify stores. Without running a server.
changedetection.io is excellent open-source software. If you would rather not self-host, configure selectors by hand, or maintain uptime for your own monitoring stack, Beaconmon covers competitor and store monitoring from free.

What changedetection.io costs
The pricing facts, without spin.
Hosted SaaS from $8.99/mo, includes a Chrome browser for JavaScript sites and EU/US proxies.
10 monitors and 1 competitor free forever. Starter at $29/mo unlocks unlimited competitors and Weekly Competitor Report.
Why Shopify stores look for a changedetection.io alternative
changedetection.io is free but general-purpose. Ecommerce store owners usually want less setup, not more.
Self-hosting is a real cost, even if the software is free.
Running changedetection.io yourself means a server, Docker or a Python environment, and ongoing maintenance. Beaconmon is fully hosted from the first signup.
Selectors are manual with no ecommerce shortcuts.
changedetection.io is a general-purpose tool. Setting it up to track a Shopify product price means inspecting HTML and writing your own selector. Beaconmon ships with presets for Shopify and WooCommerce product, price, and stock elements.
Your own store's uptime is not covered.
changedetection.io watches URLs you point it at, competitor pages included, but has no concept of monitoring your own store's availability, SSL certificate, or domain expiry. Beaconmon covers all three in the same plan.
There is no ecommerce-specific digest.
changedetection.io sends raw change notifications through its Apprise integration. Beaconmon's Weekly Competitor Report rolls every change into one readable summary built for a store owner, not a developer.
What Beaconmon covers instead
Built for stores that want competitor and uptime monitoring working in minutes, not after a Docker deployment.
Free plan: 10 monitors, 1 competitor, forever. No card, no server.
Preset selectors for Shopify and WooCommerce price, stock, and content.
Uptime monitoring and SSL expiry alerts included in every plan.
Domain expiry alerts at 30, 14, and 7 days.
Weekly Competitor Report: a weekly Slack or email summary of every competitor change.
Nothing to deploy, update, or keep running yourself.

Where changedetection.io still wins
Be honest about this. If changedetection.io is the right fit, we will say so.
Full control through self-hosting.
With 30.7k GitHub stars, changedetection.io is the most established open-source option in this space. Self-hosted, you own the deployment, retention, and data completely. Beaconmon does not offer a self-hosted option.
Broader monitor types.
changedetection.io tracks JSON APIs, PDFs, and visual changes, not just HTML content. Beaconmon is HTML-only and focused specifically on ecommerce competitor pages.
JavaScript rendering on the hosted plan.
changedetection.io's hosted SaaS includes a real Chrome browser for JavaScript-heavy sites. Beaconmon monitors server-rendered HTML only, so a headless or client-side-rendered competitor storefront may hide changes from Beaconmon that changedetection.io would catch.
Common questions
Is changedetection.io free?
The self-hosted, open-source version is free. You run it on your own server via Docker or pip and maintain it yourself. A hosted SaaS version exists starting at $8.99/mo if you want to skip the self-hosting.
Why choose Beaconmon over free, self-hosted changedetection.io?
If you do not want to run a server, configure selectors manually, or maintain uptime for your monitoring tool itself, Beaconmon is hosted from the start with Shopify and WooCommerce presets built in. It also monitors your own store's uptime and SSL status, which changedetection.io does not do at any tier.
Does Beaconmon support the same broad monitor types as changedetection.io?
No. Beaconmon is HTML-only and purpose-built for ecommerce competitor pages. changedetection.io also monitors JSON APIs, PDFs, and can render JavaScript on its hosted plan. If you need that breadth, changedetection.io covers more ground.
Can I use Beaconmon for competitor pages and changedetection.io for everything else?
Yes. Some teams run changedetection.io for general-purpose monitoring, API endpoints, PDFs, internal tools, and use Beaconmon specifically for ecommerce competitor intelligence and their own store's uptime.
