A browser built for people who ship
Zio Browser is the SayZio desktop browser for Mac and Windows: private, fully isolated profiles, a built-in device lab for testing your pages, distraction-free browsing and one-click access to your links and analytics.
Free download · Latest version 0.3.6 · macOS (Intel & Apple Silicon) and Windows · all installers
Built for the people who build pages
Zio Browser is a full desktop browser — tabs, bookmarks, history, downloads — designed around one workflow: making, checking and sharing your Sayzio pages. Your account rides along, so opening your dashboard, your biolinks or a follower's page never starts with a login screen.
Type a handle and it resolves straight to the Sayzio profile. Open the device lab and see the same page as a phone, a tablet and a desktop side by side. When you're done, close the window knowing private sessions left nothing behind.
- Signed-in session bridges to your Sayzio account across windows
- Per-profile isolation keeps clients, brands and personal browsing apart
- Private windows carry a hard wall — no history, no leftover storage
More than tabs
The tools creators and teams actually use, built into the browser.
Private profiles
Every profile gets its own cookies, logins and history — switch between work, personal and client accounts without leaks.
Built-in device lab
Preview any page across phone, tablet and desktop viewports side by side — perfect for checking your Link in Bio.
Fast & focused
A clean, distraction-free window with none of the toolbar clutter. Your pages, your work, nothing else.
Sayzio built in
Jump to your links, biolinks, QR codes and analytics from anywhere with one click — no bookmarks needed.
True private windows
Private windows keep zero traces and are walled off from every profile — by design, not by setting.
Auto-updates
New releases install themselves quietly in the background, so you're always on the latest version.
Three ways makers use it every day
The browser earns its place by removing the little frictions between "edit" and "looks right everywhere."
Check every screen at once
The built-in device lab renders your page at real phone, tablet and desktop sizes side by side — no resizing windows, no guessing how a block wraps on mobile.
One window per client
Profiles keep logins, cookies and history fully separated. Manage a client's workspace in one profile and your own brand in another without ever logging out.
Stay in the flow
A quiet, chrome-light interface and handle-aware address bar keep the path from "idea" to "published page" short — type the handle, see the page, make the change.
Zio Browser, answered
macOS (both Intel and Apple Silicon builds) and Windows. Grab the right installer above or from the downloads page.
Yes — Zio Browser is completely free to download and use. A Sayzio account unlocks the built-in link and analytics shortcuts.
Each Zio profile is a fully isolated session: separate cookies, storage and logins with zero sharing between them, so one browser can safely hold many identities.
A built-in preview mode that renders any URL across common phone, tablet and desktop viewports at once — ideal for testing biolinks and landing pages before you share them.
Sign in once and your links, pages and analytics are one click away in every window. Your browsing data itself stays on your machine.
