All your messaging and web services in one free, open-source window
Ferdium is a free, open-source desktop app that gathers all your messaging and web services in one window. WhatsApp, Slack, Gmail, Discord, Teams and dozens of others live side by side in a sidebar, so one program replaces a dozen pinned browser tabs and separate clients. It is a community-run fork of Ferdi, licensed under Apache-2.0, and the current release is v7.2.3, published on September 7, 2026.
The project is deliberately community-first: it is maintained by volunteers after Ferdi moved toward paid accounts. A Ferdium account is optional — without one, your services and settings stay entirely on your machine. Workspaces let you split services into contexts such as Home and Work, and the same service can be added several times when you juggle multiple accounts.
The honest trade-off is the one every Electron-based aggregator makes: each service runs as an embedded web view, so memory use grows with every active service, and Ferdium can only offer what each service's web version offers. There are no mobile apps. If your daily routine is a pile of chat tabs, it is a tidy, no-cost consolidation; if you need native-app performance, it will not change that equation.
Featured in our discovery: Ferdium: A Home for All Those Chat Windows
WhatsApp, Slack, Gmail, Discord, Teams and many more services live together in one app with a unified sidebar.
Group services into workspaces such as Home and Work to keep contexts separate and switch between them in one click.
Add the same service several times to stay signed in to personal and work accounts at once.
A Ferdium account can sync your setup across machines, but the app works fully without one.
No. The app works fully without an account and keeps your services and settings on your machine. An optional Ferdium account exists only to sync your setup across devices.
Yes. It is free and open-source software under the Apache-2.0 license, maintained by community contributors, with no paid tiers.
