Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 2020, this domain has about 6 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The registrar is Squarespace Domains II LLC, a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
The lowest TTL is 54 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by vercel-dns.com, indicating managed DNS hosting. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates. No CNAME was found; the observed records resolve directly to addresses.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, Permissions-Policy, clickjacking protection. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. CORS permits the specified origin https://excalidraw.com. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Vercel.
Technology Stack Analysis
The public page identifies Vercel without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
Twitter Card metadata is configured. The title has 21 characters, within a common display range. A meta description is present, with 127 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
