Campfire vs Keybase

You can invite people to join conversations even if they don't have a Campfire account. Campfire will generate a link to share and the guest will only need to enter their name to join the conversation.

When you need to make a conference call, all you need to click is "Start A New Call" and Campfire instantly embeds a phone number and password code in the message thread.

Campfire supports only iOS, but third party apps can be used for Android. There are also other third party apps that build upon Campfire and extend its functionality.

Images that are uploaded in the GIF, PNG, or JPEG formats are represented as thumbnails in the chat room.
