How do I switch from Franz to Singlebox?

Download Singlebox, sign in, and add your apps from the catalog or by pasting any website's address. Then sign in to each account. Every account gets its own profile, so you can recreate your Franz setup in a few minutes and keep using Franz until you're ready.

Can I use several accounts of the same app?

Yes. Every app or account is its own profile with an isolated session, so you can stay signed in to several accounts of the same service at once. The free plan includes 2 profiles, and paid plans include unlimited profiles.

Does Singlebox include its own email client like Franz Mail?

No. Singlebox runs your email provider's web app with all of its features. If you use several email accounts, each one gets its own profile, and you can make Singlebox your default email client so email links open in the inbox you choose.

Yes. Singlebox has a free plan with 2 profiles and cloud sync. Paid plans add unlimited profiles, app lock, built-in ad and tracker blocking, theme colors, and priority support.

Singlebox vs. Franz

The apps you already use, instead of an all-in-one messaging hub.

Franz 6, released in 2026, turned Franz into a messaging hub with its own mail client, a native Signal client, to-dos, a calendar view, and AI. Singlebox takes a lighter approach: it runs the web apps you already use, with every account signed in, in one window.

At a glance

Singlebox

A dedicated window for messaging, email, and work apps, running each service as you already know it. Best for people who are happy with their current apps and want them together in one place.

Franz

A messaging hub for recruiters, consultants, founders, and operators, with built-in mail, native Signal, to-dos, a calendar view, search across services, and AI. Best for people who want one app to replace several tools.

Your apps, or Franz's versions of them

Franz adds its own layer on top of your services: Franz Mail with a priority inbox, a native Signal client, to-dos, snippets, translation, and AI features. If you want those tools in one place, Franz offers a lot.

Singlebox doesn't replace your email or chat apps with its own versions. You get the web apps you already know, with all their features, side by side in one window. There's no new inbox to learn and nothing to move over.

Accounts and organizing

Franz runs services in isolated containers, so you can keep separate accounts for teams, clients, and personal life, and groups them into workspaces.

Singlebox gives every app or account its own profile with an isolated session, in one profile bar with optional folders, plus tabs and tab groups inside each app.

Why Singlebox

Why choose Singlebox

Keep the apps you know

Singlebox runs each service's own web app, so every feature you rely on is still there, and there's no new mail client or workflow to learn.

Every account side by side

Each app or account is its own profile with an isolated session, so a second inbox or chat workspace is one click away and stays signed in.

Simple, with room to grow

Singlebox keeps the basics simple, and adds tabs and tab groups, link rules, and custom CSS and JavaScript when you want more control.

Where Franz may be a better fit

You want a built-in mail client with a priority inbox, or a native Signal client.
You want to-dos, a calendar view, and search across mail and messages in the same app.
You want AI features, including the option to run models locally.
You use Linux. Singlebox is available for macOS and Windows.

Which should you choose?

Choose Franz if you want an all-in-one messaging hub that adds its own mail client, to-dos, and AI on top of your services.

Choose Singlebox if you want the apps you already use, as they are, together in one window with every account signed in.
