Getting Started
xcelera audits your pages and diagnoses what to fix. Add a page now and in a few minutes you'll have your first audit and an AI diagnosis of the change that will improve performance the most. The free tier needs no credit card and covers a daily audit for a full month.
Add your page
Sign up, click Add Page, and enter the URL you care about most. Your homepage is a good default.
The defaults suit most sites: a mobile device profile and a daily audit at 9am in your timezone. Everything can be changed later, so don't agonize here. When you're ready to dig into the options, Regions & Devices and Scheduling cover them.
Auditing a page behind a login? Flip Requires authentication. Those pages are audited via the API or CLI instead of on a schedule. See Secure Pages.
Watch your first audit
Leave Run first audit now switched on. The audit starts the moment you click Add Page, and you land on its page to watch it complete. An audit takes a few minutes: your page is measured from a dedicated machine under controlled lab conditions, so the result is stable enough to act on. The report covers your Lighthouse scores and Core Web Vitals. Audit Stability explains what makes the numbers trustworthy.
Read your diagnosis
Your first successful audit is diagnosed automatically. Shortly after the audit finishes, the diagnosis appears on the same page: the change that will actually move the needle for your page, backed by evidence from the audit's own measurements. AI Diagnosis covers everything it looks at.
Keep it running
One audit is a snapshot; the value compounds when they keep running. Leave the daily schedule on and the dashboard builds a score history for the page. A regression from a deploy shows up as a step in the trend instead of going unnoticed, and patterns no single audit can reveal, like a server that only slows down at certain hours, stand out within a week. Diagnoses get better with history too: each one reads your past audits, so it can tell a chronic problem from one unlucky load.
Performance Monitoring covers how to read the trend.
