Rocket chat free version

Hi everyone
i am trying to use self-hosted-server in rocket chat
Can you tell me what is the limited features that i can use and i cannot in this version through API ?

There are but it isn’t documented.
As per your thread here answered several time here:

CE is ‘free’ to download and use but has limitations. Key ones are:

  • Likely user limit around 200 users due to architectural constraints
  • Max 10,000 push notifications
  • No read receipts
  • Limits on customisations

‘Starter’ is free for up to 25 users and includes most features.
