It is super stable. After trying to build our own using firebase... This was an awesome experience that got us deployed super quick. It is fully featured and ready out of the gates requiring very little adaptation.

There are still some things that are not included in our portal management. However, engaging support has been able to resolve them.

Sendbird allows you to get up and running with a chat solution pretty quickly. We have since customized it a lot (integrating it with Slack, building notifications etc). It is pretty good for plug and play if you are looking for a basic chat service. We don't use their UI, but their UI is good straight out of the box. Their response time is a bit slow, and they have made some changes to their product without warning and detailed descriptions of those changes. All in all it was a good solution for us because we needed to focus on other things and don't have the bandwidth to worry about make sure our chat foundation is reliable. Sendbird has been pretty reliable with only a couple of times going down. Their pricing is good for what you get. If you are just looking for a plug and play chat service then you should definitely consider Sendbird. If you are looking to customize it a lot like we have, then I would suggest thinking about what you are trying to achieve, as it may be better to just start from a little lower level like socket.io. We ultimately decided on Sendbird, and have been pretty happy thus far.

Plug and Play

Needed to customize quite a bit and the customer support is not the fastest.

We wanted a simple, fast, chat solution to drop into our app. Sendbird promised this, but did not deliver.

Seemed like it had the features we wanted, small hungry team that promised a lot.

Poor quality product, terrible documentation, engineering support that didn't know how their own product worked. We paid a lot of money for this software, got locked in, have regretted it every day since. Will leave as soon as we can.

I think the product is useful and needed. Chat is quite difficult to implement into an app on both the front-end and back-end. SendBird makes it much easier to do so, but still needs work in terms of documentation and support. It was not that easy to implement a front-end solution, albeit a custom one. I would like to be able to speak with a tech support staff via chat. It was very difficult to get support over email with long wait times in between correspondence - at least when I was a non-paying member. One might say that is a crucial time to convert someone to paying. A direct line via Slack or even their own messaging service would be incredibly useful. I still have issues to this day with implementation related to connecting, temporary messages, caching, error handling, etc. There are a LOT of odds and ends that need to be taken care of, and I'm willing to bet most apps implementing this solution are not bug free or on par with more mainstream chat services and I think it should be. Overall, I like the product. I think there's a lot more that can be done with it, and I look forward to future releases.

Definitely makes it easy to add chat. Saves a ton of time and headaches. It's a better back-end solution than I could have done personally.

- Needs better technical support. - Needs a better front-end solution. - Not very easy to implement.

Very pleasant and would recommend using Sendbird to other engineers looking for chat integration.

The customer service team has been very responsive with any inquiries. Although they are a third party partner, it feels like they are in my own team. Integration was very easy and straightforward as well.

Sometimes when there are errors, we have to reach out to them, instead of them reaching out to us.

Not having to implement it by ourselves :)

On top of the customisable API, one thing I appreciated the most was how easy you can communicate with the team behind SendBird. Had a request regarding some push notifications with WatchOS that were actually missing and within a few days, after some email exchange, here it was.

The fact it is not open source I would say. Open sourcing it would make it better for the community.

Team is willing to help you - starting from your first contact. all relevant platforms we need to integrate the chat on, are supported. if you have some custom requests, the team is willing to find a good solution to enable your business implement their plan.

the ui kit could offer more functionality.

Great tech support. Always proactive when we face issues

Some features were missing when we initially tied up and had to custom implement on our side

We've been working with SendBird for nearly 2 years. The customer service has been excellent and the learning curve to get up and running, minimal. Already a great service/product when we began, it's been nice seeing the team refine and expand the product. Each iteration has been well thought out and implemented. Highly recommended.

Ease of use, minimal learning curve

A couple times in the early days I found the documentation lacking a little but it appears this is no longer an issue.

What makes chat services available to users without direct management. Considering the labor cost, the use of the solution seems to be efficient. The part where sustained service is maintained at a reasonable speed for use.

Constraints on custom. It feels like extra cost for administrative features but not cheap. I am currently using the moderation tool but it is not easy to check the chat history because the filter function is not advanced. It would be nice if you could experience paid services before contracting.

I launched my app Pro Photo Shoot using SendBird as the engine for in-app messaging. I was very pleased with the way the API handled conversations, as it really took a lot of work out of the process, which can be very complicated if building from scratch. A few things in the suggestion box: - Faster, faster, faster! Make the API as fast as possible. - Improve your console to make it easier to drill down into a conversation when needed

Ease of use. Decent SDK and REST interface.

Documentation is a little thin. It could be more robust with details, examples, and use cases.

Absolutely terrible. We ended up cancelling our subscription, and asked for a partial refund for the unused portion of the costs. They refused. We contacted the credit card company and asked to rebate the charges, and Sendbird fought it. We were unable to get anything at all. What kind of a company takes your money and refuses to rebate unused service. We are are a B2C startup and every dollar counts. At the same time, I believe in customer service, and would never screw a customer out of their money. What a bunch of dirtbags! I would never do business with this company again! We ended up having our devs make a chat in house. Stay away. Far away.

Very little - the basic interface was ok

They wanted to charge us way more for moderation tools, which we believed should be an essential part of any chat software. And we were in development mode with virtually no users - so we needed time to ramp up to scale.

No need to develop chatting tool, Low cost for using such tool

Easy to use, quick response for issues or inquiries. Also it's easy to implement at the beginning of the service.

Our product relies heavily on the messaging aspect, so we chose our chat SDK really carefully. Before settling on SendBird, we tried about 10 different chat SDKs. SendBird was the clear choice for us due to how customizable and flexible it is. This flexibility gave us the freedom to easily build many features using their SDK. Sendbird is still evolving. We sometimes experience service issues and interruptions from time to time. However, their customer support is really amazing and they have been extremely helpful. They even built specific features we suggested. TL;DR: Go for it!

Flexible & Customizable, great customer support

Infrequent service interruptions and bugs

An (almost) out of the box production-ready and performant chat as a service solution with incredible group communications features that is easy to integrate and build on.

For our use case the large scale public and private group chats were absolutely essential. The performance is impressive, the API straightforward, and the iOS client code provided was good enough for us to build on and ship production worthy code quickly.

The API has a few design flaws and, while superior to the competitors offerings that we have direct experience with, the iOS client code is pretty mediocre. Building truly high quality client UI/UX will still involve a significant amount of effort.

SendBird makes it really us to build out complex chat features with minimal overhead! This helps us quickly differentiate vs. other competitors.

Documentation could use some improvement, but their team is amazingly helpful in filling in any gaps.

Chatting service

Customer service and feature.. the SDK is quite easy to implement. The performance is good.

The price, quite expensive. And the feature is quite limited for paying user. I hope I can get more MOU.
