An invite-only Slack network specifically for UX designers and researchers: one of the longest-running, most established communities on this list.
The channel structure is the real strength: dedicated spaces for portfolio feedback, salary discussion, freelance leads, and specific tools, so you're not shouting into one giant firehose channel.
Best for working UX designers and researchers past the total-beginner stage: the application process and community norms assume you already have some practical footing.
It's invite-only with an actual screening step, so budget a little time for the application: you won't get instant access the way you would with an open Discord.
Designer Hangout is a dedicated, invite-only network of UX designers and researchers.
