How will pricing work?

Check out the pricing page here. We’d love to chat with you to better understand your use case(s), as we understand that every application is different and you may require a custom plan to suit your needs.

Chatkit is nice, but can it do X? I have a feature request, what should I do?

Just ask us! Email us at chatkit@pusher.com. We’d love to hear your requests.

Can I use Chatkit in production?

If your use case requires a broadcast chat or large group chat (>100 end users per chat room), we do not recommend Chatkit. However, we would love to understand your specific needs in order to best serve you. If this sounds like your use case, Pusher Channels may be a better fit for you. Please contact us at chatkit@pusher.com so we may help you find the solution that best fits your use case.

Do you support Emojis?

😍 🤗 💯 (in short, yes)
