You can make a Roblox community from the app or website, but it is not actually free to create one normally: Roblox says creating a community requires a one-time payment of 100 Robux.

How to create it

  1. Log into your Roblox account.
  2. Go to Communities.
  3. Choose Create a Community.
  4. Enter the name, description, and emblem.
  5. Set the join settings, such as public or manual approval.
  6. Finish by paying the 100 Robux fee.

If you want it without spending money

The only practical way is to earn 100 Robux first, then make the community. Common methods people use include:

  • Creating and selling game passes.
  • Selling clothing.
  • Making and monetizing experiences.
  • Receiving donations in donation games or communities.

Important note

Be careful with “free group” videos or posts that claim you can just claim an existing group. Official Roblox support still says a community costs 100 Robux to create.

TL;DR: You can create a Roblox community, but the official method costs 100 Robux; “free” usually means earning the Robux first.
