Keep captures consistent: Activate
stealth=true to render pages the way a normal browser session would and keep scheduled monitoring jobs dependable. Enable StealthThe Stealth Mode Browser feature captures full-page screenshots using a browser profile with reduced automation signals. Some websites alter their appearance, show interstitials, or block content when they detect an automated browser, which makes captures inconsistent. By using Stealth Mode, you get reliable, consistent rendering — ideal for scheduled captures of your own sites or public pages.
Why Use Stealth Mode?
Stealth Mode is useful when a website responds differently to automated browsers — for example, by serving altered layouts, interstitials, or partial content. Stealth Mode reduces those automation signals so the page renders the way it does for a regular visitor, keeping captures consistent from run to run. Here are a couple of scenarios where Stealth Mode is beneficial:
- Monitoring your own sites: Keep scheduled captures of your production and staging pages rendering consistently.
- QA and documentation: Capture public pages as real visitors see them, without detection scripts changing the layout.
- Public page monitoring: Keep recurring captures of public product and pricing pages rendering reliably from run to run.
Default Stealth Setting
By default, Stealth Mode is not activated. To use it, you need to explicitly enable it by setting the stealth parameter to true in your request.
How to Enable Stealth Mode Browser
To activate Stealth Mode for a screenshot request, append the &stealth=true parameter to the URL query string. This instructs the system to reduce automation signals so the page renders as it would for a regular visitor.

Benefits of Stealth Mode
Using Stealth Mode offers several advantages:
- Consistent Rendering: Pages display as they would for a regular visitor instead of showing interstitials or altered content.
- Accurate Data Capture: Ensures that screenshots are taken under conditions that are less likely to alter the appearance of the web page due to detection scripts.
- Resilient automation: Keeps scheduled captures and webhook workflows running without manual retries.
