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:

  • MIT-licensed open source — the Editor and Guardian browser extensions, including the client-side cryptographic boundary, are public and auditable (the hosted sync service is proprietary). Independent reviewers can inspect exactly how cookies are read, written, and (optionally) synced.
  • End-to-end encrypted sync — passphrase-derived key (PBKDF2-SHA-256), per-record AES-256-GCM encryption, server stores only ciphertext. Your cookies appear on all devices without the provider being able to read them.
  • Cookie history with undo — 90-day history (Pro) lets you restore a cookie you edited or deleted by accident.
  • Multi-account profiles — named cookie snapshots for one-click identity switching (work vs personal) in a single browser window.
  • Reproducible builds — verify the Chrome Web Store binary matches a tagged Git commit by comparing SHA-256 checksums.

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:

  • Smaller footprint — roughly 120 KB packed versus CookieVault’s ~480 KB. CookieVault carries the sync client and crypto library even if you never enable Pro.
  • No account, ever — Cookie-Editor never prompts for an account. CookieVault’s local mode is identical, but the existence of a Pro/sync tier is visible in the UI.
  • Longer track record — Cookie-Editor has years of stable releases and a large review history. CookieVault is newer.

If CookieVault’s additions are worth it for you, migration takes about a minute:

  1. Open Cookie-Editor on any site, click its export button, and save the JSON
  2. Check the download page for the verified Editor release status. The package is not yet publicly available.
  3. Open CookieVault → Settings → Import → JSON
  4. Select the file you exported in step 1
  5. Verify your cookies appear with correct domains, values, and flags
  6. Optionally enable Pro sync to replicate across devices
