Also called ferdium app, ferdi fork

Ferdium communityProductivity

A community fork of Ferdi/Franz that hosts many chat sites in one window. The process is Ferdium.exe.

What you need to know

Ferdium wraps many chat sites. It is not Rambox.

Ferdium.exe is a community Franz/Ferdi fork. Rambox.exe is a different workspace app. Native messenger exes are still separate products.

Feex says

If Ferdium.exe is huge, I would count the services you added. This is a site wrapper, not Rambox, and not native WhatsApp.exe by itself.

What is Ferdium?

Ferdium is an Electron shell that embeds many chat sites. The Windows executable is Ferdium.exe. It is not Rambox and not a single messenger.

If you have never used it

If you want WhatsApp, Slack, and mail in one window, this is Ferdium, a community fork of Ferdi and Franz. It is not Rambox. Download it from ferdium.org. The process is Ferdium.exe. Each service is still that website inside the shell.

What is it used for?

Many messengers in one window

WhatsApp Web, Slack, and others as services. WhatsApp.exe is still a different native client if you also installed that.

Community recipes

Ferdium services are site wrappers. A broken recipe is a Ferdium issue, not a Windows service.

A Franz/Ferdi upgrade path

Old Ferdi users were pointed here. Rambox is a different company.

Who is it for?

People who outgrew a pile of chat tabs
Users migrating from Ferdi or Franz
Anyone comparing it with Rambox

Current status

Ferdium (2022) is a current workspace messenger from Ferdium community. The vendor still points Windows users at https://ferdium.org/.

How old is it?

Franz started the multi-chat shell. Ferdi forked it. Ferdium forked Ferdi in 2022 after Ferdi stalled. It is a 2020s community continuation, not a 2016 Rambox-only story.

Versions

Major channels first. Exact build numbers are not all verified here.

Current Windows build

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current supported Windows 10 or Windows 11 release, per the vendor
RAM	Enough for Windows plus this app. Heavy projects want more.

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
Ferdium.exe	Main Windows executable

Startup components

Ferdium can start with Windows from its own setting so all services reconnect.

File locations

Common Ferdium locations
Typical install	C:\Users\<you>\AppData\Local\Programs\Ferdium\

File formats

whatever the wrapped sites use

Common problems

A site login loop inside a service

That is the wrapped website. Clear that service in Ferdium before you reinstall Windows.

People uninstall Rambox to remove Ferdium

They are separate apps. Ferdium.exe stays.

Getting unstuck

Install from ferdium.org

A Ferdi 2021 exe is stale. Ferdium is the current community fork.

Check GitHub issues for a broken recipe

github.com/ferdium/ferdium-app is the project tracker. Rambox Freshdesk is the other vendor.

Quit Ferdium.exe from the tray

Wrapped sites can keep the Electron host awake.

Alternatives

Rambox if you want that commercial workspace. Wavebox if you want a Chromium workspace browser. Native WhatsApp or Slack if you only need one chat.

Official help and downloads
