Can you vibecode this?

Yes

A native Mac app in Swift/SwiftUI that reads browser state and surfaces a unified sidebar — this is pure code, ships, no licences, no catalogue, no human delivery. The browser breadth is coverage work added over time, not the core reason people pay.

For owners

Own SupaSidebar? List it for sale.

Founders read this page looking for a business to build like your $2K+/mo one — some would rather buy one that already works. They skip the line, you get a clean exit. $25 one-time, no commission.

Why it works

Value proposition
One sidebar manages tabs and bookmarks across every Mac browser.
Problem
Tabs, bookmarks and history are siloed inside each separate browser.
Audience
Mac users who run multiple browsers daily.
Business model
Free tier with a 7-day Pro trial, then one-time purchases per device tier.

Why people pay SupaSidebar

Users build up spaces, bookmarks and browser history inside SupaSidebar over time, making it costly to abandon. The app also has 3,500 users and a string of named, published endorsements from Apple press figures, giving it credibility a fresh copy starts without.

Product complexity
Low
A web dashboard for account and license management sits alongside the native Mac app.
Data
Low
No external data sources are needed; all tab and bookmark data comes from the user's own browsers.
Integrations & infrastructure
Low
Standard payment processing and iCloud sync are the only outside services required.
Human operations
Low
One founder builds and supports the product solo, with no required headcount.
Regulation / hardware
Low
No licenses or regulatory approvals are required to sell this software.
