OnePanel is an all-in-one messenger for Mac and Windows, with split view, a notification inbox, and productivity extras like a combined Teams calendar and usage insights.

What is Singlebox?
Singlebox is a desktop app for the apps you work in every day. Pick from 65,000+ apps in the catalog or add any website, and every app or account becomes its own profile with an isolated session, so all your apps and accounts stay signed in side by side. It runs on macOS and Windows.
What is OnePanel?
OnePanel is a commercial all-in-one messenger and desktop workspace for Mac and Windows. It shows up to five apps side by side in split view and collects notifications in an inbox with history. This comparison is based on the current version of OnePanel.
1. Built for every work app
OnePanel focuses on messengers. Singlebox is designed for every app you work in, from email and chat to project tools. Keep each app's pages in tabs and tab groups, group apps into folders, and jump anywhere with the command palette.
2. Links go where they belong
Singlebox can be your default browser and email app. Link rules send each link to the right profile, so a client link opens in that client's account, and everything else opens in your regular browser.
3. Sync on every plan
Singlebox syncs your profiles, bookmarks, and settings across your computers on every plan, including free, so a new computer is ready as soon as you sign in.
4. Room to grow
When you want more control, Singlebox has custom CSS and JavaScript, proxies, and auto-reload for each app, plus the 1Password, Bitwarden, LastPass, and Dark Reader extensions.
