How this service works
Prüft am Objekt seite den Befund Zeit bis zum sichtbaren Renderstart.
Output
Returns the measured time (in milliseconds or seconds) until the first visible render event occurs when loading the specified page, giving a concrete front-end performance data point for render start latency.
Example use cases
Pre-launch page speed audit
“Before we go live, can you measure the render start time for https://staging.myshop.com so I can make sure visitors see something quickly?”
Competitor rendering benchmark
“I want to know how fast https://www.competitorsite.com starts rendering compared to our own site — can you check the time to first visible render start for that URL?”
Regression monitoring after deploy
“We just pushed a new release — can you test the render start time on https://www.myapp.com so I know if we accidentally slowed things down?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/renderstart/seiteWhen to prefer
Use this endpoint when you need to measure specifically the time to first visible render start (first paint latency) for a web page, particularly when building performance audits, CI/CD regression checks, or competitive benchmarking workflows. Prefer this over generic uptime or full-load-time checks when the user cares specifically about perceived render speed from a visitor's perspective.
Side effects
- Non-public or unreachable URL returns an error or timeout
- Invalid URL format causes a validation rejection
- CSS selector matches no element, falls back to first match or returns an error
- Very slow or unresponsive target sites may cause measurement timeouts
- Rate limiting or bot-blocking on the target site may prevent accurate measurement
