Cookie Security Inspector
Inspect raw Set-Cookie headers for Secure, HttpOnly, and SameSite coverage before shipping changes.
Set-Cookie headersOne per line
Security posture
Secure: true · HttpOnly: true · SameSite: Lax
Secure: false · HttpOnly: false · SameSite: missing
FindingsMissing protections
Transmit cookies over HTTPS only when using Secure.
HttpOnly helps reduce client-side script access to cookies.
SameSite can reduce cross-site request exposure.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You copied one or more Set-Cookie headers and need to review their protection flags.
You want to check whether browser auth or session behavior may be explained by missing cookie attributes.
You need a quick summary for a ticket or review without manually parsing each cookie string.
Session and browser-auth debugging
Cookie inspection helps explain why a session may behave differently across environments, browsers, or deployment paths.
Security hygiene review
Teams can run a fast local pass on copied cookie headers before deeper application testing or release sign-off.
Support and escalation evidence
A concise cookie summary gives security and platform teams cleaner evidence than a long raw capture alone.
Common mistakes to avoid
These are the checks that usually keep the output useful instead of misleading.
Looking only at one cookie when the browser behavior depends on several cookies together.
Treating a cookie with Secure and HttpOnly as automatically fine without considering SameSite and the surrounding workflow.
Assuming the quick findings replace actual browser and application behavior testing.
Learn how to use this tool
Inspect copied Set-Cookie headers so Secure, HttpOnly, and SameSite coverage is easier to review before shipping or debugging browser auth behavior.
