Facilitates user communication with rich features
In our company, we are using Sendbird for building a chat feature within our salon application.  I am using the Flutter framework to implement the chat feature, which facilitates communication between users and businesses, specifically salon shops There are many useful features with Sendbird. I…

Automation features and user-friendly interface support seamless communication
Slack is very supportive in terms of communication between my colleagues and clients. While working with the reimbursement feature, I found the automation capabilities on Slack to be incredibly useful, allowing me to automate messages for specific dates or times and even to greet someone on their birthday. I haven't specifically used the channel organization feature of Slack, as I am added to channels, but I use it with Airtable, which automates notifications to a specific Slack channel when a user fills out a form on our website. In my experience, Slack is a stable product for communication, and I appreciate its automation features and integration of AI capabilities for enhancing specific functions.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There are many useful features with Sendbird."
"Sendbird is reliable and generally crash-free."
"Sendbird is very flexible, and they have made great strides towards optimization."
"Sendbird provides many features for real-time messaging, such as receipt ID and typing indicators."
"The most valuable feature for us, besides chat, was file transfer, as we used it for sending files and images in chats."
"The backend system was managed by Sendbird, eliminating the need for caching systems or local storage on user devices."
"Features similar to WhatsApp, such as online and offline statuses, message reactions, and replies, add significant value."
"The Sendbird developer portal provides each step, including methods, making it easy to implement."
"With respect to being a clean and efficient communications platform, I think that it does the job quite well."
"It allows to facilitate communication, allowing us to create channels for updates, file sharing, and photo sharing within our team profiles."
"Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated."
"The solution is scalable."
"Slack helps us keep the conversation focused and avoid multiple threads that create more confusion. I would say that has been the biggest advantage for us."
"Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat."
"The product gives the best user experience."
"I use Slack for communication with my colleagues."
 

Cons

"The documentation for integrating with the Flutter framework is lacking detailed information."
"More analytics tools could be integrated into Sendbird."
"A major issue was the requirement for a separate connection to Sendbird, resulting in a delay when initiating the chat."
"The documentation for integrating with the Flutter framework is lacking detailed information. Initially, I struggled to connect users and manage tokens for active and offline sessions, which caused frustration."
"Their pricing is very high compared to competitors, which is a concern for us."
"Impersonating a user or using a template user to send messages for development purposes would be very useful."
"At times, there are unexpected behaviors where the documentation suggests something different from how the SDK actually behaves, requiring us to create workarounds."
"I thought that there should be the audio and the video call functionality as well."
"The product crashes when I use it on the desktop."
"The integration with SharePoint doesn’t work properly."
"Sometimes Slack behaves unexpectedly and shuts down without notification or support communication."
"Slack should add a feature to schedule meetings."
"I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom."
"Slack feels clustered and hence it should improve its design and UI."
"The only area of concern that I have is with the inability to preview received documents without having to download them first."
"Slack's interface is not simple for me. It's not a user-friendly interface"
 

Pricing and Cost Advice

"There is a starter plan for $399 per month, and a pro plan for $799 dollars."
"The solution’s pricing is cheap."
"When it comes to pricing, it is on the expensive side."
"The pricing can range up to about twenty bucks a user. You can spend a lot of money, especially if you're talking about thousands of users. Generally speaking, Slack is less expensive than Teams. Slack doesn't include all the bells and whistles that Teams does. So you can go from a $6 license in Microsoft 365 to a $50 license per user per month, and there's a lot more you can do in the $50 license."
"Slack is definitely worth the money."
"It is an affordable solution."
"It is less expensive than one of its competitors."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"I would rate the tool's pricing a four out of ten."
