What is Cookie & Header Inspector?
Cookie & Header Inspector is part of the stbox.dev developer sandbox. Parse and inspect Set-Cookie headers, SameSite attributes, and security flags.
It sits in the Crypto & Certs category and is designed for day-to-day debugging, demos, and learning — without forcing you to paste secrets into opaque third-party SaaS forms whenever client-side execution is enough.
