OSS TanbouOverview
Flow Browser is a TypeScript desktop browser built on Electron and Chromium. It combines multiple profiles, Spaces, a sidebar, command palette, persisted tabs, Chrome extensions, native ad blocking, sleep tabs, and Widevine support in a minimal interface. The latest release as of September 17, 2026 is v0.12.0.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Organize tabs around profiles, Spaces, a sidebar, and command palette
The README highlights multiple profiles and Spaces, quick access to bookmarks/history/settings from a sidebar, command-palette navigation and search, and persisted tabs across restarts.

Keep Chromium compatibility while adding extensions, ad blocking, sleeping tabs, and Widevine
Flow can install Chrome Web Store extensions and includes a native ad blocker, resource-saving sleep tabs, and Widevine for DRM-protected content. It is an Electron/Chromium product rather than an independent browser engine.
For users who want Arc/Zen-inspired browser organization while keeping the Chrome extension ecosystem in a GPL codebase
It also provides a useful reference for developers interested in building browser UX on top of Electron and Chromium.
It is still a v0.x browser and the README lists basic browser capabilities as upcoming
As of v0.12.0, the README still lists tab reordering, downloads, pinned tabs, custom search engines, and tab previews under Upcoming Features. Validate the basics you rely on before replacing a primary browser.
Privacy-focused positioning does not change the fact that the engine is Electron/Chromium, so security and privacy review should include Chromium/Electron update cadence and extension permissions.

Supplemental curator note
It offers Arc/Zen-inspired organization with Chromium compatibility, but v0.x maturity and several upcoming basic browser features warrant testing.
