Arc alternative: how do I replace Arc?

Size as a product trait from day one

Arc never sold itself as small. It sold a feeling: spaces as rooms, tabs as objects, Chromium as interior design. Interior design is not a 15 MB object, and when a fashionable shell pauses, the people who only needed a browser inherit a large Chromium plus a story. Capsule is the opposite: about 15 MB, native and reassuringly boring on disk. You can keep it next to a project folder without a keynote to justify why it exists. Arc made browsing feel expensive in a good way; Capsule makes the file feel cheap in the useful way.

From a Mac-first installer to a folder on USB

Arc arrived Mac-first, then added a late Windows chapter, and remained an installed app with an account-shaped gravity. Portability was never the point. Capsule is a folder you drop onto a USB stick or an external SSD, including machines you do not administer, with no installer and no admin rights. The transition away from Arc is often exactly when people realise they wanted a file rather than a membership in another browser company’s next experiment. The host stays as you found it after you unplug.

A device-encrypted vault instead of an account graph

Arc’s calm UI did not change the fact that Chromium is a different kind of business. Sync and account features still lived in a cloud-shaped product. Komby Vault is encrypted on this device, and Capsule itself never stores the master password; recovery runs through an authenticator app rather than through a mailbox. That matters when the previous browser’s company is busy with something else. Zero tracking is Capsule’s product stance — not an ask to migrate spatial bookmarks into the next branded Chromium.

Pro audio was never Arc’s point, and that is fine

Arc’s theatre was visual, not sonic. Chromium Web Audio stayed Chromium Web Audio underneath the spaces. For live mixing it was never a serious path, only a pretty one with the same latency as every other Chromium. Capsule’s live engine is native when Nightclub is on, and this page does not pretend Arc competed there. The honest sentence is simple: fashionable UX did not buy you a device driver. If you only needed tabs in a tidy column, any remaining Arc install still opens the web; if you needed a portable workstation that can also hit hardware, you were in the wrong product the whole time.

Replace Arc without waiting for the next spatial browser

• Replacing Arc is a continuity problem, not a theme problem. Export what still exports, copy Capsule beside the sites you use, and skip the wait for whichever spatial Chromium ships next. A 15 MB file does not need a transition narrative.
• If Arc was your Mac home, the Safari comparison is on the Safari page; if you only ever wanted off Chrome, read the Google Chrome page. Capsule is the portable object those pages describe, not a spiritual successor with another sidebar.
• Rebuild your spaces as Capsule workspaces if you must. The habit worth keeping is the on-device vault, not a company relationship.
• After a week, if what you miss is Arc’s theatre, that is design nostalgia. If the stick carries Capsule and the host carries nothing left behind, the transition is complete.
