Where Arx stands
Availability, open source, Arc, the engine, assistants and passwords.
This page is a first draft. It may change before the public beta.
When can I try Arx?
The public beta for macOS starts by the end of November 2026. Join the CaptureContext newsletter to get an email the moment it opens.
Will Arx be open source?
Yes. The source code will be published alongside the first beta, so anyone can read it, build it and check what the browser sends.
How is Arx related to Arc?
Arx is an independent CaptureContext project inspired by Arc's approach to browsing. It is not affiliated with Arc or The Browser Company. You can import your Arc profiles, spaces and pinned tabs when you switch.
Why Chromium?
For web compatibility and Chrome extensions. Arx runs a Helium-derived Chromium engine under a native macOS interface written in Swift.
Do I need to use AI to browse?
No. Agent access is off until you connect an assistant, and each assistant only gets the spaces and capabilities you grant it. You can revoke a grant at any time.
Can an assistant see my passwords?
No. When a site needs you to sign in, the assistant hands the page to you and every assistant pauses while you type. Arx tells the assistant whether you finished, never what you typed.
Which Macs does it run on?
Arx targets current macOS on Apple silicon. Intel builds are not validated yet.
Can Arx save my passwords?
Not yet. Passwords and passkeys are planned: website passkeys and Apple's iCloud Passwords both wait on Apple's approval. Until then, sign in the way you would in a new browser.
Does Arx sync between my Macs?
Not yet. Sync through iCloud is planned for before 1.0. Today, move your setup with an Arx archive.
Does Arx cost anything?
No. Arx is free, with no credits-based AI plan.
