Parallel Spaces
Run multiple instances of the same app on your Mac — dual WhatsApp, two Telegrams, two Slacks, side by side. Fully isolated copies, separate logins, zero mix-ups.
Requires macOS 14.0 Sonoma or later · Native, no virtual machine · On the Mac App Store
Other platforms have let you run two copies of the same app for years. Mac never did — until now. Parallel Spaces brings true multi-instance to macOS the way it should have been all along: native, instant, and built to feel like the rest of the system.
If you juggle a work account and a personal one, manage clients, or share a Mac with family — you've felt the pain. Parallel Spaces fixes it for good.
Run two Slacks, two Mails, two browsers at once. Each one stays signed into its own account — no switching, no logout.
Freelancers and agencies: keep each client's tools and logins in their own space, with zero chance of cross-posting.
Developers and QA: spin up a clean, isolated copy of an app to test a second account in seconds.
No setup files, no terminal, no virtual machine. Just pick an app and go.
Choose any app on your Mac — or turn a website into one.
Give it a name, a colour and a badge so you always know which is which.
It creates a separate launcher with its own private, isolated storage.
It opens as its own app, with its own account. Make as many as you need.
Fast, native and quietly powerful — Parallel Spaces gets out of your way.
Every space gets its own private storage. Logins, cookies, history and settings never bleed between them.
No emulation, no containers, no VM. Your apps run at full speed — because they're the real apps.
Turn any website into a standalone Mac app — its own icon, window and storage, with native notifications.
Colour-code and badge each space so a glance at the Dock tells you exactly which account it is.
Optional menu bar access and launch-at-login keep your spaces a click away.
Make a space disposable — it wipes its own data when you quit. Perfect for one-off logins.
Parallel Spaces supports the apps already on your Mac — and any website you want to treat like one.
Gmail, WhatsApp Web, Notion, ChatGPT, your CRM — give each one a real Mac app: a Dock icon, its own window, and its own isolated storage.
Messaging clients, browsers, Electron apps and many more. Parallel Spaces detects how each app stores its data and isolates a second copy correctly.
macOS won't normally open two copies of one app. Parallel Spaces does — here are the setups people reach for most. Each runs side by side, signed into its own account.
Run two WhatsApp accounts on a Mac at once — personal and business side by side, each with its own chats and notifications. Works with the WhatsApp desktop app or WhatsApp Web as a web app space.
Open dual Telegram on macOS in separate windows. Keep work and personal Telegram fully isolated — separate logins, separate message history, no switching.
Apps that normally allow only one copy — like Viber and Signal — can run twice in isolated spaces, so two numbers stay signed in at the same time.
Run multiple Slack instances on Mac, one per company or client, each in its own window. No more logging out of one workspace to reach another.
Keep a main and an alt Discord signed in together. Each space is a separate, isolated copy of the same app — perfect for moderators and multi-server users.
Turn any website — Gmail, Notion, ChatGPT, Instagram, your CRM — into its own isolated Mac app, and run the same site multiple times with a different login each.
Parallel Spaces is built to keep your accounts apart — and to keep your data yours.
Each space is sealed into its own storage. One account can never see another's data.
No analytics, no telemetry, no profiling. Parallel Spaces doesn't watch what you do.
Your spaces and their data live entirely on your device. Nothing is uploaded.
No sign-up to use Parallel Spaces. Sandboxed and notarised through the Mac App Store.
Clean, familiar, and right at home on macOS.
On the Mac App Store. Your accounts, finally apart.
