This site is essentially a login screen with no context. There's no company name, no privacy policy, and no way to contact anyone running it. For a website that asks for your email and password, that's a serious problem.
Most legitimate services — even small ones — provide at least a basic about page, a privacy notice, and some sign of who's behind the operation. Here, you get none of that. The domain is hidden behind the 'dev' TLD with no ownership records, and the site has no history in the Wayback Machine, meaning it's either very new or deliberately untraceable.
If you're asking 'is crucial-blush-quax49gl.edgeone.dev a scam,' the answer is that there's no evidence it's legitimate. A site that collects credentials without transparency is a classic setup for credential harvesting. Avoid entering any information here and look for a service with a visible business identity, clear policies, and a track record you can verify.
