Workspace URLs, invite links and which to encode
Slack identifies workspaces, not people, by subdomain: yourteam.slack.com. That's what this page encodes, and it's the right destination when the audience already has an account or will be invited through the normal flow — new hires, contractors, a partner team.
For open communities, an invite link is usually what you want instead. Those are long, contain a random token, and can be revoked or expire, so paste them through "Any link" and treat printed copies as disposable. A workspace URL, by contrast, stays valid for as long as the workspace exists.
The practical placements are onboarding sheets, desk cards for a new starter, conference stands for community Slacks, and laminated signs in shared spaces. All of them beat writing a subdomain someone has to spell back to you.
Every Slack code made here is static: the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down. There's no account, no watermark and no scan limit — download it once and it keeps working for as long as the Slack link behind it does.
