How Sitewell compares
Six tools people use for the checks Sitewell runs, compared honestly. Each page has a table, the part where the other tool is genuinely the better choice, and the part where Sitewell is. Nobody wins all six.
httpstatus.io alternative
httpstatus.io checks status codes and redirect chains in bulk. Sitewell runs the same checks free, then repeats them on a schedule and alerts when one breaks.
WhereGoes alternative
WhereGoes traces where a link ends up. Sitewell traces the same chain with per-hop timing, maps redirects in bulk, and can watch the route on a schedule.
redirect-checker.org alternative
redirect-checker.org traces redirects and can vary the user agent. Sitewell times every hop, maps redirects in bulk, and re-checks the path on a schedule.
Screaming Frog alternative
Screaming Frog is a desktop crawler with an installer and a licence. Sitewell runs the specific checks in a browser: free, no install, and it keeps checking.
UptimeRobot alternative
UptimeRobot tells you when a site goes down. Sitewell watches the failures that keep returning 200: redirects, certificates, dead links and page speed.
TrackSSL alternative
TrackSSL watches certificates and warns before they expire. Sitewell watches the certificate, the domain registration behind it, and the rest of the site too.
Why these pages concede so much
A comparison page that finds nothing good to say about the other tool is marketing, and everyone reading it knows within a paragraph. So each of these names at least two situations where the other tool is the one to reach for, and in one case the free tier being compared is plainly better than ours.
The useful version of this question is not which tool is best. It is which tool fits the check you are trying to run, on the site you are responsible for, at the frequency you need to run it.
Skip the comparison and run a check
Bulk status codes, redirect chains, certificate and domain expiry, broken links. All free, none of them behind a signup.
