Cookie-Editor alternative

TL;DR: CookieVault is an open-source Cookie-Editor alternative on Manifest V3. It matches Cookie-Editor’s lightweight per-site editing and adds MIT-licensed code, end-to-end encrypted cross-device sync, cookie history, and reproducible builds. Cookie-Editor remains a good choice for users who want the smallest footprint and do not need sync.

CookieVault is a free, MIT-licensed cookie manager that serves as an open-source alternative to Cookie-Editor, the popular Manifest V3 cookie editor by Moustachauve. Both let you view, edit, add, and delete cookies from a per-site popup. The difference is that CookieVault publishes its source code, offers optional end-to-end encrypted sync, and ships reproducible builds — while Cookie-Editor is closed-source, local-only, and lighter weight. This page compares them honestly so you can pick on the merits.

In short: This is not a teardown. Cookie-Editor is well-maintained, Manifest V3-compatible, and widely used. CookieVault competes on open-source transparency and sync, not by claiming Cookie-Editor is unsafe — because it is not.

Per our content standards, we do not attack competitors. Cookie-Editor (by Moustachauve) is a legitimately good tool: a clean popup, fast local editing, a large and satisfied user base, and active maintenance on the current Manifest V3 platform. If you are happy with it, you have no urgent reason to leave.

CookieVault exists for a specific subset of users — those who want to audit the source code, sync cookies across devices with zero-knowledge encryption, or verify the shipped binary against the published source. If none of those matter to you, Cookie-Editor’s smaller footprint is a real point in its favor.

What CookieVault adds

In short: Open-source code, end-to-end encrypted sync, cookie history with undo, multi-account profiles, and reproducible builds. These are the reasons to choose CookieVault over a closed-source local-only editor.

Five capabilities CookieVault offers that Cookie-Editor does not:

In short: Smaller install, faster cold popup, no account ever, and a longer track record. For pure local editing, these are genuine advantages.

Honesty cuts both ways. Three areas where Cookie-Editor has the edge:
