SnapRender

Included in every plan

Scheduled website screenshots that tell you what changed

Pick a page and how often. SnapRender captures it every hour, day or week, compares each capture with the one before, and emails you when the page changes, with a link to both versions side by side. Set it up in the dashboard, or with one API call.

Stop checking pages by hand

Pricing pages, terms, client sites, your own release: the pages that matter change without notice. A schedule watches them for you and keeps the receipts.

  • Hear about it the same day

    An email or a webhook as soon as a capture differs from the last one by more than your threshold. Quiet pages stay quiet.

  • See exactly what changed

    Before and after side by side, with the changed areas outlined and the share of the page that changed. No squinting at two tabs.

  • Keep proof of every version

    Every capture is dated and stored with its SHA-256 hash, for 7 to 180 days by plan. Download any of them when someone asks what the page said.

Set up in a minute

SnapRender runs the schedule, the browser and the comparison, so there is nothing to host or maintain.

  1. Add the page

    Paste the URL, choose every hour, day or week, and how big a change should alert you.

  2. SnapRender captures it on time

    A fresh render in real Chrome each time, with cookie banners and ads removed, on desktop or any device preset.

  3. You hear about real changes

    Each capture is compared with the one before. Above your threshold you get an email, a change.detected webhook, or both.

Schedule settings: check every hour, day or week, alert on any change, bigger edits or big changes only, and email alerts

In the dashboard, or in your code

The same schedules either way. Start in the dashboard, then automate when you need to.

No code: the dashboard

Add pages, see every capture, compare versions and change the alert settings. Your schedules, their latest captures and their last change at a glance.

Code: one API call

Create the schedule with POST /v1/schedules, then receive a signed webhook when the page changes.

Questions

Does SnapRender run the schedule, or do I need my own cron job?

SnapRender runs it. Add a page in the dashboard or with POST /v1/schedules and it is captured every hour, day or week, compared with the capture before it, and kept in a dated history. You do not need a server, a cron job or an image diff library. If you already have a scheduler, you can still call the screenshot API from it.

How does SnapRender decide that a page changed?

Each capture is compared with the previous one, pixel by pixel in small blocks, so anti-aliasing noise does not count. The result is the share of the page that looks different: one changed price is a few hundredths of a percent, a new section several percent. You choose what alerts you: any change (even one changed number), bigger edits such as a new line or banner, big changes only, or your own threshold.

How do I find out about a change?

Three ways, and you can use all of them. An email to your account address (turn it on per schedule), a signed change.detected webhook for your own code, and the schedule page in the dashboard, which shows the capture before and after the change side by side with the changed areas outlined.

How often can a page be captured?

Every hour, day or week. The free plan includes 1 daily or weekly schedule; paid plans add hourly captures, more schedules (5 on Starter up to 300 on Scale) and longer history (14 to 180 days).

What does it cost?

Schedules are included in every plan. Each capture counts as one render of your monthly quota: a daily schedule uses about 30 renders a month, an hourly one about 720. Failed captures are refunded, and when the quota runs out captures are skipped, never billed as overage.

Can I use the captures as evidence?

Every capture is stored as a PNG with its capture time and SHA-256 hash, so you can show what a page displayed on a given date and that the file has not changed since. Download them from the dashboard or list them with GET /v1/schedules/{id}/captures.
