Cookie Injector

Cookie Injector is a developer-focused cookie mover: get your browser login state into whatever tool needs it, fast. KEY FEATURES • One-click copy: cookie string / full curl command / fetch snippet, straight to clipboard • Multi-format export: JSON (with httpOnly/secure/sameSite metadata) or Netscape cookies.txt (ready for curl -b) • Cookie editor: view, search, edit (all fields), add, delete, or clear all cookies for the current site • Session snapshots: save multiple login states per domain and switch accounts in one click — automatic backup before every switch, rollback on failure, and even "clear all" is backed by a snapshot • Optional local service: pair with a self-installed local component to serve cookies over a localhost HTTP API, so curl, scripts and API tools always read the latest values (everything above works without it) PRIVACY & SECURITY • Cookies are read only when you click, with per-site just-in-time permission (optional permissions) • Your data never leaves your machine: no remote upload, no analytics, no ads, no tracking • Snapshots live only in your browser's local storage WHO IT'S FOR Frontend, backend and QA engineers who need to reuse browser login state in curl, scripts, or API debugging tools.
