Developer experience

Monitor page changes with periodic scrapes.

Use the Scrapes endpoint to capture a page snapshot as Markdown, store it, then scrape again later and diff the results.

See what changed on a public page

A website change monitor fetches the current page text, compares it to the snapshot you saved last time, and highlights added and removed lines.

  • Live scrape, not a cache

    Olostep fetches the public URL now and returns clean markdown, the same way the website-to-markdown tool does.

  • Compare to your last check

    The first run saves a baseline in this browser. The next run on the same URL reports unchanged or changed with a line diff.

  • JSON for workflows

    Copy the snapshot, hash, and diff. Recurring alerts belong on Olostep Monitors with email, Slack, SMS, or a webhook.

How it works

Each tool is designed around a direct job: provide the input, get a useful output, and move it into your workflow.

  • 1

    Enter a public URL

    The first check stores a baseline in this browser so later visits can detect a change.

  • 2

    Olostep scrapes the live page

    The request uses the Olostep Scrapes API and returns markdown for the current contents.

  • 3

    Review the snapshot and diff

    See baseline, unchanged, or changed, then copy JSON or set up a scheduled monitor for alerts.

Built for practical workflows

These tools are small on purpose: they solve the conversion job quickly, then point teams toward the API path when the workflow becomes recurring or high volume.

  • Pricing and copy checks

    Re-check a product or pricing page after a launch and see which lines moved.

  • Policy and docs reviews

    Capture a terms or docs page now, then confirm whether the published text changed later.

  • Competitor snapshots

    Keep a local baseline of a public competitor page without signing up for a scheduled watch.

Need alerts on a schedule?

Create an Olostep monitor for recurring snapshots and email, Slack, SMS, or webhook alerts. See the Monitor docs or the Monitor API page.

Frequently asked questions

Product & Capabilities

  • It scrapes a public page and compares the current text to a previous snapshot so you can see whether the page changed.

  • This page is a one-off snapshot in your browser. Olostep Monitors is the scheduled product: recurring runs, snapshot history, and email, Slack, SMS, or webhook alerts.

  • Change detection needs a previous version. The first successful scrape saves that version locally. Check the same URL again to see if it changed.

Usage & Automation

  • Only in this browser, in localStorage, keyed by URL. Olostep does not keep a server-side history for this free tool.

  • No. Each click is a live scrape. For recurring checks and alerts, create a monitor in the Olostep dashboard.

  • Use Olostep Monitors. Describe what to watch, set a frequency, and add a notification channel or webhook. See the Monitor API docs.

Pricing & Plans

  • The page UI is free to use. Live scrapes use the Olostep API configured for this site and are rate limited.

  • Standard scrapes are usage based. See Olostep pricing for the current plan details.

  • Olostep offers free credits for new users, so teams can test extraction before scaling.
