Agelum Browser for macOS, Windows and Linux

A browser built around your apps and your sessions.

Keep work, personal and client accounts in isolated sessions. Open your apps from one desktop. Tabs stay grouped by site, and your passwords stay in a vault only you unlock.

What's inside

Everything a working day needs, nothing it doesn't.

An app desktop

Group your web apps into cards and drag them between groups. Each app runs in its own sandboxed view, opened from the bar on the left.

Isolated sessions

Named sessions keep their own cookies, sign-ins and proxy. Be signed in to two accounts of the same site, side by side.

Tabs grouped by site

Pages of the same site share one tab, with their pages in a second row. Hover a tab for back, reload, bookmark and Read later.

A vault you unlock

Saved passwords, addresses and cards, encrypted with your system keychain. Touch ID or a PIN before anything sensitive is used.

Bring your history

Import bookmarks and history from Chrome, Brave, Edge, Arc, Firefox, Safari and more, into the session you choose.

An agent beside your apps

Apps that provide an agent open it in a side panel, next to the page you're working on.

Sessions

One window. Every account kept apart.

Each session is its own browser inside the browser. Pick which saved credentials it may use and route it through its own proxy. Private sessions forget everything when they end.

Security

Passkeys, security keys and a vault that asks first.

Touch ID passkeys

Sign in to sites with passkeys bound to this device, kept separate per session.

Security keys

USB and NFC FIDO keys for two-step sign-in. Touch the key when it blinks.

Step-up unlock

Touch ID or your vault PIN before saved credentials are filled in.

Agents can't read them

Your page passwords and cards are kept apart from the secrets apps and agents may use.

For developers

Ship your web app as an Agelum app.

Describe it in a manifest, ask for the permissions it needs, and use the window.host API. Add a plugin for work that runs outside the page, or an agent provider for the side panel.
