Use cases

Who uses Account Switcher?

Real scenarios where one-click session switching saves hours — from staging tests to AI workflows and multi-client work.

Web Dev UAT & QA

Jump between admin, user, and guest roles on staging without logging out. Ideal for regression testing, bug reproduction, and sign-off across personas.

AI rate & token limits

Hit the daily cap on ChatGPT, Claude, or DeepSeek? Rotate between saved accounts instantly — each session keeps its own auth state and usage quota.

Multi-account SaaS

Manage personal and work accounts on the same platform — Stripe, Notion, Figma, or internal dashboards — without the logout-login loop.

Client demos & support

Switch to a client's sandbox or demo account before a call. Support teams can reproduce issues in the exact account context without asking for credentials again.

Agency & freelancer

Juggle multiple client environments from one browser. Save each client's logged-in session and switch in one click — no separate browser profiles needed.

Social & marketing teams

Handle several brand or client accounts on social platforms and ad managers. Stay signed in to all of them and swap contexts without clearing cookies.

How to use

From login to one-click switch

Save any authenticated session locally, add multiple accounts per website, and switch between them instantly — no logout required.

Developers

Built for developers, by a developer

Open source, auditable, and privacy-first. Account Switcher runs entirely in your browser — no backend, no telemetry, no account required. Inspect the code, fork it, or load it unpacked in seconds.

Every session is a local snapshot of cookies and web storage. The extension uses Manifest V3 with strict TypeScript, works on Chrome and Firefox from one codebase, and keeps your data in chrome.storage.local — never on a remote server.

  • Open source on GitHub — audit the code yourself
  • TypeScript + Manifest V3 — modern, strict, cross-browser
  • No telemetry, no external APIs (except optional favicon fetch)
  • Session data = cookies + localStorage + sessionStorage snapshot
  • Auto-sync keeps active sessions fresh after re-login
