In their own words, as submitted to SaaSHub.


Most people don't run one browser anymore. They run several, split across profiles. Safari for personal, Chrome for work, a separate Chrome profile for development, maybe Firefox for testing. Each profile is its own world of logins, history, and extensions. macOS never got the memo. Click a link...

As answered by people managing Burly.click and Diffyn.
Burly.click's answer
Profiles are the destination. Burly lists every browser profile (Safari Work, Chrome Personal, Chrome Dev) as a first-class choice, not buried in browser settings, and finds them automatically as they change. Make each one yours with an emoji or account photo, a curated petal color, and its own shortcut key, so the picker becomes a board of faces you recognize at a glance.
Diffyn's answer:

Burly.click's answer
Burly is made by Matt Senter, an independent founder and developer who designs, builds, and ships small, focused products end to end. Burly is one of them, a tool he wanted on his own Mac and decided to make properly. No team, no investors, no roadmap by committee: just software built with care and shipped when it's ready.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
