## What it is
Browserosaurus is an open-source macOS browser prompter that registers itself as the default browser and shows a picker menu of installed browsers whenever a link is clicked from a non-browser app. It is built with Electron, React, and TypeScript.

## Use cases
- choose which browser opens links clicked in other apps
- prompt for browser on every link click on macOS
- set a favourite browser with a hotkey
- preview the URL before opening it in a browser
- use multiple browsers with per-link selection

## When to choose
- you use macOS and switch between multiple browsers
- you want a visual picker instead of URL-based rules
- you want an open-source alternative to default-browser utilities

## When to avoid
- you need automatic per-URL rules (use Finicky instead)
- you need Windows or Linux support
- you want actively maintained software - the project is no longer maintained
