I created a chat on our page, and I also created a chat for a website portal and a chat in a Chrome extension.
It was a chat between a borrower and a loan officer on a mortgage application platform. The borrower could ask questions, and the loan officer could respond and request documents, signatures, etc.
Sendbird helped by implementing the chat, which was the main purpose for using it.
The most valuable feature for us, besides chat, was file transfer, as we used it for sending files and images in chats.
I would want to add features like impersonating for chats or adding a user from the admin to help test chats. Impersonating a user or using a template user to send messages for development purposes would be very useful.
I have been working with Sendbird for almost a year.
We did not face any problems with performance.
Sendbird is scalable on their end, but not on the customer's end. However, we did not notice any issues, probably since it is scalable.
As for customers, we have up to 10,000 users.
I don't remember escalating any questions to technical support. Most issues could be reported directly on the documentation page, which could be fixed easily.
We did not have any other chat solution before Sendbird. We used Sendbird from the start.
The initial setup was straightforward, and the documentation covered 100% of our needs. Everything was clear.
We had 30 developers working on the initial setup and on the solution in general.
I would most likely recommend Sendbird as it is easy to use and easy to set up.
I'd rate the solution nine out of ten.
