Parallex or browser profiles?

A browser profile is the free, built-in way to be signed in to two accounts of the same website. It doesn't reach Mac apps. Parallex does, and can also make a separate browser of its own, opened on its own, with links sent where you choose.

When a profile is enough

If both accounts are websites you use in the browser (two Google accounts, a client's Jira, a second Slack in a tab), a profile does it, for free. Chrome, Edge, Brave, Firefox and Safari (since Safari 17) all have them.

When Parallex is better

Using both

Parallex works with profiles rather than replacing them. A workspace can send its links to a Chrome, Brave or Edge profile, and a browser instance (a separate Chrome with its own data folder) sits beside your profiles, with its windows outlined in its color. Two separate Chromes has the details.

Questions

Do Chrome profiles have separate Dock icons on a Mac?

No. Every Chrome profile is a window of the same Chrome, with one Dock icon. Chrome can make a desktop shortcut per profile, but the windows still belong to one app.

Does Parallex work with Safari?

Safari can't be copied, as it's one of Apple's apps. Safari has profiles of its own, and Parallex's website instances (each a small WebKit app of its own) work for any website.
