Introducing Feature Tags

Discover key service capabilities at a glance with new feature tags.

You’ll now find feature tags across AltStack.jp: a quick way to spot distinctive characteristics of each service.

We’ve started with three tags:

ALIAS
Indicates that a DNS provider supports ALIAS or ANAME records, or something similar to Cloudflare’s CNAME flattening. These records let you point root domains (like our own https://altstack.jp) directly to services like CDNs.

WAF
Stands for Web Application Firewall. Services offering a WAF help protect your site from threats like SQL injection, XSS, DDoS attacks, or unwanted bot traffic.

EN
Shows that a service is available (fully or partially) in English. Handy for international teams or non-Japanese speakers.

More tags will come as the site evolves. Have a tag idea or spotted something we missed? Feel free to reach out!
