Pages change without warning

Catch visible page changes before customers do

Render a page once or keep checking it on a schedule. RenderLog shows what changed, keeps the accepted baseline and leaves the evidence ready to review.

Built on Cloudflare infrastructure for reliable browser-based page checks.

How it works

Choose the path by the job

Use the API for files. Save a website check when the same page needs owners, baselines, alerts and repeat runs.

API output

Render a page result

Call RenderLog from a backend job, CI pipeline or product feature to create screenshots, PDFs, HTML, Markdown or stored files.

Visual checks

Watch a page over time

Save high-value URLs with viewports, waits and flow steps when a page needs repeatable visual control.

What both paths share

Approve the baseline

Choose the result that represents the accepted state. Later runs compare against that decision.

Run it where work happens

Start checks manually, from CI, through the API or on a schedule when Automation is enabled.

Review only meaningful changes

Open changed cases, keep the result and notify Slack, Teams or a webhook when action is needed.

Keep the operational trail

Keep result files, labels, logs and billing context attached to the same page or API run.

Coverage

What stays with every page run

Render outputs

Screenshots, PDFs, HTML, Markdown and files use the normal successful-run price. Async video keeps the same run history and adds a separate per-video run rate.

Baseline review

Promote an accepted state, compare later runs and keep the reason for the decision.

Saved website checks

Group priority pages with viewports, waits, flow steps and owners.

Real page controls

Use headers, cookies, selectors, waits, blocked requests and device presets.

Use cases

Where teams use RenderLog first

Start where a missed page change already costs trust, support time or release confidence.

Review visible changes after a release

Product releases

Review visible changes after a release

Trigger a Check Suite from CI, wait for the page to settle and review only screens that changed.

Fits pricing, signup, checkout, payment and account pages.

Keep landing pages from drifting

Marketing sites

Keep landing pages from drifting

Save the accepted version, then catch broken CTAs, shifted sections, missing blocks and pricing edits.

Run checks after CMS updates, campaigns and pricing changes.

Show clients the page state, not opinions

Client work

Show clients the page state, not opinions

Agencies keep a visual record for client sites, run regular checks and show exactly what changed.

Use it for weekly reports, content updates and post-release checks.

Protect content pages tests rarely cover

Content teams

Protect content pages tests rarely cover

Docs, help centers and long pages can break without failing a test suite. Give them baselines and history.

Compare pages after CMS edits, translations and template changes.

Make the next page change reviewable

Pick one page that matters, approve its current state and let the next run show whether anything visible changed.
