Hibira vs PubNub Chat: chat APIs compared
PubNub bills chat on its realtime platform from $98 a month for 1,000 users; Hibira charges $49, counts each user once a month and keeps unread counts on the server.
PubNub sells a realtime platform with a chat SDK on top, billed by monthly active users or transactions. Hibira's Chat API is a chat service of its own: the server keeps conversations in order, counts unread messages and pushes to people who are away. The differences are how use is counted, how long messages are kept and how far the free plan goes.

When PubNub is the better fit
- You want one vendor for chat, IoT messaging and other realtime traffic, billed together.
- You need edge locations worldwide rather than one region in Asia.
- You want unlimited message history with a yearly Pro contract.
When Hibira is the better fit
- You want 1,000 chat users for $49 a month instead of $98, and 500 free instead of 200.
- Some of your users send a lot: on Hibira they still count once.
- You want the server to keep unread counts, read marks and order, so every client sees the same thing.
- Your app already uses the Pusher protocol, and chat should share the same account, app and connection.
