Pull the current month credit usage to monitor how many pages are being rendered against your plan.
List Cached Pages
Search for all currently cached URLs to identify which parts of the site are already processed.
Set Render Options
Configure specific browser settings or wait times for the render process to ensure heavy scripts load.
Purge All Cache
Clear every cached page in the account. Use this for major site redesigns or global CSS changes.
Get Page Metadata

Frequently asked questions

Ceven sends the target URL to Prerender which uses a headless browser to execute all JavaScript and wait for the DOM to stabilize. Once the page is fully rendered, Prerender sends back the static HTML. Ceven then feeds this HTML into the model for analysis. This process bypasses the typical limitation where AI agents see only the initial empty shell of a React or Vue app. By using this flow, the agent can interact with the actual content that users and search engines see, making it possible to automate SEO audits that would otherwise require a human to manually inspect the page source in a browser.
Yes. When Ceven calls the render endpoint, it monitors the HTTP response codes and the content of the returned HTML. If Prerender returns a timeout or a blank page, Ceven identifies this as a rendering failure. You can set up a workflow where the agent periodically checks a list of priority URLs and sends a Slack alert the moment a page fails to render. This is critical for catching breaking changes in your frontend code that might block search engines from indexing your site, allowing you to fix the issue before it impacts your organic search rankings.
One key quirk is the cached nature of the service. Prerender caches pages to improve performance and save credits, but this means you might see an outdated version of your page if you just pushed a change. To solve this, Ceven provides a Clear Page Cache action. Additionally, Prerender has strict rate limits based on your plan tier. If you attempt to render thousands of pages in a very short window, you may encounter 429 Too Many Requests errors. Ceven handles this by implementing a retry logic with exponential backoff to ensure your audit completes without crashing.
Standard scrapers often just pull the initial HTML response from a server, which for modern apps is often just a script tag and a blank body. Prerender actually runs the JavaScript in a real browser environment. Ceven leverages this by using Prerender as a middleware. Instead of trying to execute JS locally, which is resource heavy and unstable, Ceven asks Prerender to do the heavy lifting. This ensures that the agent sees the final rendered state of the page, including content fetched via API calls after the initial page load, which is exactly how Googlebot operates.
Yes. Since Prerender can render any public URL, Ceven can be configured to snapshot competitor pages on a schedule. The agent can pull the prerendered HTML of a competitor every week, extract their current pricing or feature lists, and notify you of changes. Because it uses a headless browser, it can capture content that is dynamically injected into the page, which simple scrapers usually miss. This allows you to build a competitive intelligence dashboard that is based on the actual rendered experience of the competitor site rather than just the raw source code.
Yes, through the Set Render Options action. You can tell Prerender to wait for a specific element to appear on the page before taking the snapshot or to ignore certain scripts that might slow down the render. Ceven can manage these settings programmatically. For example, if you have a page with a slow third party widget that is not important for SEO, you can configure the agent to skip that element. This optimizes the rendering time and ensures that the agent gets a clean snapshot of the primary content without waiting for unnecessary assets to load.
Every time Ceven requests a page that is not already in the Prerender cache, it consumes one render credit from your Prerender account. If the page is already cached, no credit is used. To optimize your spend, we recommend using the List Cached Pages action to see what is already available. You can also build a workflow in Ceven that only triggers a render when a deployment is detected in your CI CD pipeline. This prevents the agent from wasting credits on pages that have not changed, ensuring your budget is spent only on fresh content verification.
Prerender has a default timeout for how long it will wait for a page to finish loading JavaScript. If a page exceeds this limit, Prerender returns a timeout error. Ceven captures this error and can be programmed to react. For instance, the agent can try again with a longer wait time specified in the render options or flag the page as a performance risk. This is actually a useful SEO signal, as pages that take too long to render for Prerender are likely to be flagged as slow by search engines, potentially hurting your Core Web Vitals scores.
