Satori
Free WebKit Mac browser with Spaces, Split View, Arc import and no telemetry; source repo still private.
Satori is a free, native Mac browser on Apple's WebKit, published by 0mind LLC (developer: tretten) since 2026-09-25 and updated almost daily; the current release is v0.13.7 (2026-11-11). Tabs run across the top or down a sidebar that folds to an icon rail, with up to nine Spaces per window that share one profile. It imports Arc's spaces and pinned tabs, opens links from other apps in a small Kensho window, blocks ads and cookie banners itself, and translates pages and summarises articles on the Mac. There is no account, sync or telemetry. The MIT-licensed source is in a private repository: the public repo holds the README, licence and builds only. It began as a fork of driceroland/Search and needs Apple silicon.
Built-in AI
AI optional
Only Apple's on-device model (macOS 26): Summary in Reading mode and history search by meaning (opt-in); translation is on-device too. No cloud AI.

Organization
| Feature | Satori | Arc | Note |
|---|---|---|---|
| SidebarVertical sidebarTabs live in a vertical sidebar that is the main tab UI and can be hidden. | ◐ | ✓ | Tabs sit across the top or down the left (picked in Welcome, ⇧⌘S switches); the sidebar folds to an icon rail.github.com |
| SpacesSeveral workspaces per window, each with its own pinned and open tabs, switched by swipe or shortcut. | ✓ | ✓ | Up to nine Spaces per window, each with its own name, icon, tabs and pinned tabs; ⌘1–9 or a two-finger swipe switches.satoribrowser.com |
| ProfilesProfiles per Space (shareable)Each Space can use its own browser profile (separate cookies, logins, history), and one profile can be shared by several Spaces. | ✕ | ✓ | One profile for all Spaces: sign-ins are shared. Only a Make Web App gets separate sign-ins.satoribrowser.com |
| FavoritesGlobal favoritesPinned icons at the top of the sidebar shared by every Space (Zen calls them Essentials). | ✕ | ✓ | No pinned icons shared across Spaces; "Favorites" are the most-visited sites under the address field.satoribrowser.com |
| Pinned TabsPinned tabs & foldersPer-space pinned tabs that act like bookmarks, with nested folders. | ◐ | ✓ | Pinned tabs are per Space and keep their place, but have no folders; Arc folders are flattened on import.satoribrowser.com |
| Live foldersSidebar folders that fill and refresh themselves from an outside source, such as GitHub pull requests or an RSS feed. | ✕ | ✓ | No live or self-filling folders; bookmark folders are plain and filled by hand.github.com |
| ArchiveAuto-archive tabsUnpinned tabs close automatically after a set time and stay recoverable in an archive. | ◐ | ✓ | Idle tabs sleep after 30 min and tabs unopened for a week are offered for closing; no archive, only Recently Closed.github.com |
| Theme pickerSpace themesPer-space colour or gradient themes. | ◐ | ✓ | Light, dark or Auto plus a per-site page colour for the bars; a Space has only a name and an icon.github.com |
Browsing

|---|---|---|---|
| Split ViewTwo or more tabs side by side in one window. | ◐ | ✓ | Two pages side by side with a draggable divider; no third pane.github.com |
| PeekLink previewOpen a link in an overlay without leaving the current page (Zen calls it Glance). | ◐ | ✓ | No Peek on ordinary links; a link leaving a pinned tab's site opens in a small Kensho window (switchable off).github.com |
| Little ArcMini windowA small, chrome-less window for links opened from other apps or a quick search. | ✓ | ✓ | Kensho: links from other apps open in a small window with the address on top; Open (⌘O) keeps the page. On by default.github.com |

| Tab SwitcherRecent-tab switcherCtrl+Tab jumps back to the tab you used last and cycles in recently used order. | ◐ | ✓ | ⌃Tab follows row order by default; a Settings › Tabs option switches it to your last five tabs by recent use.satoribrowser.com |

Compatibility & migration
| Feature | Satori | Arc | Note |
|---|---|---|---|
| Arc importImports Arc spaces, pinned tabs and folders. | ✓ | – | Bookmarks › ⋯ › Import Spaces from Arc brings spaces and pinned tabs (folders flattened, favorites into the first Space).satoribrowser.com |
| Chrome extensionsInstalls extensions from the Chrome Web Store. | ◐ | ✓ | Chrome Web Store links install on macOS 15.4+, but the maker calls it alpha (many work, not all); the site still says Bitwarden only.github.com |
| DRM streamingNetflix, Disney+, Spotify web and other DRM video/audio play, through Widevine or, on WebKit, FairPlay. Chromium forks need a Google Widevine licence; FairPlay counts once a major service is confirmed playing in the app. | ? | ✓ | System WebKit, so FairPlay is the only DRM; no Widevine in the bundle and playback was not tested. |
| PasskeysWebAuthn passkeys, Touch ID and the system/iCloud keychain. | ✕ | ✓ | Build lacks Apple's browser passkey entitlement, so WebKit refuses passkeys; the 0.8.0 notes claim them, nothing in the app backs it.github.com |
| SyncSpaces, pinned tabs and settings sync across devices. | ✕ | ✓ | No account, no sync and no iCloud; history, tabs and bookmarks stay in encrypted local files.github.com |
| Mobile appiPhone, iPad or Android app that shares spaces with desktop. | ✕ | ◐ | Mac only (macOS 15+ on Apple silicon); no iPhone, iPad or Android app.github.com |
Extras

| Custom ShortcutsShortcut editorMost browser keyboard shortcuts can be remapped in Settings. | ◐ | ✓ | Settings › Shortcuts rebinds a set of actions (new tab, sidebar, Split View, reader, translate, float), not every menu item.github.com |

| Feature | Satori | Arc | Note |
|---|---|---|---|
| Manifest V2 extensionsThe older extension format Chrome removed in 2025. Needed for full uBlock Origin and other extensions that block requests. | ◐ | ✕ | WebKit loads MV2 manifests but its webRequest events cannot block, so full uBlock Origin cannot block.github.com |
