While people love using text messages on their phone, online open-source chat continues to grow in popularity and diversity. I remember the days when using online chats involved signing into your email account and then you could use your AIM or Yahoo chat that was attached to it. 

Of course, today there are popular social media chat plug-ins such as Facebook Messenger. However, a social media chat box may not be appropriate for business teams. If you are a business or individual that is looking for a good and reliable source of online communication, you can  easily find the right one for your needs.

The right online open source chatbot can make communication with your team easier and more secure. With so many people working remotely in places all around the world, a reliable source of online communication is necessary.

As of now, KChat is still a free open-source solution. 

Some other open-source chat options may be more fleshed-out at the moment. However, downloading KChat  may be a good opportunity to contribute to or watch an open-source chat platform grow over time..

Final Thoughts on These Open-Source Chats

Now that we have reviewed these 6  open-source chat options, you may have a better idea of which one may be right for you or your team. Each option has different features and different uses to consider before downloading or buying.

For example, Rally would not be an ideal open-source chat for a work team. This is clearly something that is more for personal use among friends and family. The good thing about this particular chat is that it provides a private way to plan events without worrying about whether your invite page on a social media platform remains private or not.

Plus, a social media event page can be vulnerable and you would have less control over it. A chat like this allows you to keep your events among your small circle. In addition, it also allows the entire group to participate, as opposed to just checking “yes” or “no” for an invite. and KChat both have source code on GitHub, which is a popular community for developers.  However, Kchat  still has a long way to go, but it provides opportunities for eager people to contribute.

Both and Matrix stand out as open source options for communicating internally and externally.  These open-source chats provide the most versatility in terms of the types of channels you could use them on and who you can talk to. In terms of technological advancements, Matrix seems to live up to the movie that is named after. Its ongoing work with virtual reality, particularly 3D video chat, is something to watch out for.

However, if you are a company that is eager to grow or maintain great customer service, look no further than Chatwoot.  Recently, I've noticed more and more chatbots on websites that I've been going to and I've wondered if there is a live person behind that.

To my surprise, sometimes there have been live reps. After doing research on these open-source chat options, I realized that I may have been at the other end of a Chatwoot webBot and it's pretty cool.  Say goodbye to being placed on hold on  a customer service phone line. Simply go to a website and have almost instant communication with somebody at the other end of the chat box.

Before you invest in an open source chatbot , think about the needs of your company or your social circle. Consider whether you have the resources to maintain an open source chat on your own server, or if you should pay more for the company to host it on their cloud service. 

Whatever you decide, there are plenty of options for your needs and many of these open chat sources continue to develop more enhancements every day.
