Self-hosted Changedetection.io runs in a container your team maintains, and the hosted plan still leaves filters, proxies, and LLM keys to you. Visualping runs in the cloud: paste your list into the Bulk tab or ask the assistant, and checks start on our servers.
Alerts lead with a sentence like "Competitor raised Enterprise pricing from $499 to $699/mo." Your sales team can paste it straight into Slack.
Visualping Business, from $100/mo billed annually, includes 5 team members, shared workspaces, and team comments on every Report. Changedetection.io documents no team seats, roles, or shared workspaces.
Changedetection.io filters noise with rules, or with AI intent prompts once you connect your own LLM key. Visualping's IMPORTANT flag works out of the box: it surfaces the one change that matters and records the other 49 as minor.


Visualping AI labels every change IMPORTANT or not, on every plan. Your team scans the IMPORTANT row and skips the rest, with no rules or API keys to set up first.
Changedetection.io's hosted plan includes EU, US, and Tor proxy locations, and residential proxies are an account you bring. Visualping runs every check in its own cloud, and Business teams can ask us for residential or country-specific proxies for sites that reject bot traffic.
Individual alerts catch each change. Visualping rolls a week of changes into one Report.
Reports come with Business plans, with AI summaries, team comments, and IMPORTANT flags at the top.


Inside Visualping: the AI summary

The AI tells you what to read first. Big moves up top. Share in one click.
No Docker to run and no AI key to bring. The assistant, Discovery, and bulk tools come built into your Visualping dashboard.
Chat inside your dashboard. Ask it to create a monitor, change a schedule or notifications, run a check, or flag a change. It knows your monitors and answers questions about Visualping.
Every plan, in betaDescribe what you want to watch, in your own words. Discovery suggests up to five pages at a time, with the reason each one fits, matched to what your workspace already monitors. Start the ones you like in one click. Searches use no credits.
Every planPoint it at a domain you already monitor. Visualping watches for new URLs, starts monitoring the pages that match what you care about, and pauses the pages that stop mattering. Your page allowance, and your alerts, go to the pages that count.
Solutions plans, on requestPaste a list of URLs, with names if you have them, and create every monitor at once. Then select monitors in your list to pause, run, delete, or change the check frequency, notifications, and alert condition in one go.
Every plan, including FreeBulk import creates monitors up to your plan's page limit. Domain Monitoring is available with Solutions plans, on request.
The setup playbook for catching pricing changes, product launches, and content updates without checking each page by hand.
