Security-header grade

A live check of the HTTP security-response headers linear.app sends, the same class of signal as securityheaders.com. Present headers score points; missing ones do not.

HEADER HYGIENE
B
75/100
Content-Security-Policy
Strict-Transport-Security (HSTS)
X-Content-Type-Options
X-Frame-Options
Referrer-Policy
Permissions-Policy
What this is, and is not. This grade reflects only the publicly observable HTTP response headers of linear.app, measured automatically. It is a hygiene indicator, one signal among many. It is not a security audit, not a penetration test, and says nothing about Linear's internal systems, code or data handling. Many secure sites score below A because headers like Content-Security-Policy are commonly omitted.

What Linear is used for

  • Bug and issue tracking
  • Sprint / cycle planning
  • Roadmaps
  • Engineering project management

FAQ

What technology does Linear use?

The hosting, CDN and framework signals we can detect from linear.app's public HTTP responses are listed in the "Detected stack" section above. They are read from the site's own responses at load time, so they reflect what Linear exposes publicly, not a definitive or complete stack list.

Is linear.app safe?

This page reports linear.app's publicly observable security-header hygiene as a letter grade, shown above. Security headers are one signal of good front-end practice, not a full security audit, and they say nothing about Linear's internal systems or data handling. Treat the grade as informational.

What are the best alternatives to Linear?

Widely used alternatives include Jira, Shortcut, GitHub Issues. The right choice depends on your workflow, budget and team size.
