Everything the classics did — done right
Built for developers, QA & power users
Inline editing
Edit values and SameSite in place
Click any cookie to expand a precise editor: change the value, flip Secure or HttpOnly, and set SameSite to Lax, Strict, or None. No raw JSON unless you want it.
Profiles
Multi-account profiles, one click
Save a full cookie snapshot per account and switch between them in a single click. No more logging in and out to test as a different user.
Search
Real-time search and filtering
Type to filter by name or value instantly, across every domain. Find the one cookie that matters in a sea of session and analytics noise.
Portability
JSON, CSV & HAR — in and out
Bring cookies in from any tool and take them anywhere. Round-trip your full cookie set with every flag preserved, or hand a teammate a HAR for repro.
CHIPS-aware · light & dark
Partitioned cookies, understood
Native support for partitioned cookies (CHIPS) — the modern standard the legacy tools never updated for. Editor ships light and dark, both WCAG AA.
P = partitioned by top-level site.
Import your existing JSON export in seconds — every cookie, every flag, intact.
Simple pricing. Free is genuinely useful.
One purchase unlocks Pro across both Editor and Guardian.
Take control of every cookie.
