When you visit mcweb-dpvrhafpp6l7.edgeone.dev, you get a 404 error instead of a working website. That's the single most important fact: the site doesn't serve any content. For any legitimate online service — whether it's a business, a blog, or a portfolio — a 404 on the homepage is a clear sign that something is broken or the site isn't actually live.
Is mcweb-dpvrhafpp6l7.edgeone.dev safe? There's no evidence it's dangerous: it isn't blacklisted, its SSL certificate is valid, and it uses modern encryption. But safe and trustworthy aren't the same thing. Without a functioning page, you can't verify what the site is supposed to do, who runs it, or whether it would protect your data if it ever went live.
This domain is a subdomain of EdgeOne Pages, a hosting service from Tencent Cloud. It was likely created for testing or as a temporary placeholder, then abandoned or never fully deployed. If you stumbled on this link expecting a real site, your best move is to move on. There's nothing of substance here to evaluate.
