The story of PageCrawl

Started by developers, now for everyone. PageCrawl monitors websites for changes and uses AI to tell you which ones matter.

Why PageCrawl exists

Websites change without notice. Prices move, stock sells out, terms and policies are rewritten, regulators update guidance and documents are replaced, usually without an announcement.

Checking pages by hand does not scale. Simple page watchers alert on every cookie banner, rotating ad or timestamp, so real changes get lost in the noise, and many websites are not built to web standards, which makes typical monitoring tools miss changes or fail to load the page at all.

AI made filtering easier. But fetching a page's text and asking an AI what changed is the easy part. The hard part is loading real-world pages reliably, including ones behind logins or built in unusual ways, capturing the right part of the page on every check, keeping history and evidence, and delivering alerts to the right place.

PageCrawl was built to watch the pages that matter, filter out the noise and explain each real change in plain language, so people only look at what is worth their time.

PageCrawl began as a few scripts Laurynas Sakalauskas wrote to keep track of a handful of pages. Alternatives existed, but they were unreliable, noisy or missed the changes that mattered. The scripts sent an email when something changed, and they turned out to be useful to other people too. After about a year of work they became PageCrawl, launched in June 2018.

PageCrawl started as a tool built by developers, for developers. Today it is for everyone. Watching a single page takes a couple of clicks and no technical knowledge, while teams with advanced needs get 30+ tracked element types (prices, availability, documents, feeds, DNS, SEO and more), CSS and XPath selectors, browser actions that click, type and scroll before a capture, a REST API, webhooks and an MCP server for AI assistants.

Teams and individuals use it to follow competitor prices, stock, policies, regulatory pages, documents and anything else published on the web. PageCrawl is not an uptime monitor: uptime tools answer "is the site up?", PageCrawl answers "what changed on the page?".

What we believe

Independent

PageCrawl is bootstrapped and funded by its customers, so it answers to the people who use it.

Simple first, powerful when needed

Simple monitors take a couple of clicks. Advanced teams get selectors, browser actions, the API and the MCP server.

Reliability first

A missed change costs more than a noisy one, so making every check load and capture the page correctly comes before new features. Monitoring works the same with or without AI.

Private by default

Data is hosted in the EU. PageCrawl does not sell user data or use customer data to train AI.

Who is behind PageCrawl

PageCrawl is built and run by developers, led by its founder Laurynas Sakalauskas, from Lithuania, European Union. Bootstrapped: funded by customers, with no outside investors. Customer data is stored in EU data centres (Amsterdam, Netherlands), and the business runs on subscriptions: it does not sell user data or use customer data to train AI.
