ChatGPT is a powerful generative AI tool developed by OpenAI. You enter text prompts in a conversational way, and it gives you a detailed response.

Sure, it is not perfect. But, sometimes it is incredibly helpful. No matter what you do with it, unfortunately, it is not an open-source solution.

As a proprietary option, it isn’t beneficial in every way. So, what are some open source ChatGPT alternatives? Here, let me highlight the best ChatGPT alternatives that are open-source in nature.


Not all ChatGPT alternatives function the same way. Some solutions are purely meant for developers to create their own chatbot on top of it. And, a few others offer a chatbot or demo for you to test.

Reasons to Look for Open-Source ChatGPT Alternatives

Relying on any single service is bad for the consumers. The same goes for ChatGPT.

In addition to that, here’s why we should look for open ChatGPT alternatives:

  • Get transparency on how our data is being handled.
  • You can choose to build your own solution, saving money in the process.
  • Customize the ChatGPT alternative as per your requirements.
  • You are not locked on to the policies of a single company. The open-source solution can be flexible as per your needs.
  • Contributions to the open-source project will make an impact on everyone across the globe.

I do not intend to say that ChatGPT is bad, or you should stop using it. However, “we” as the users should benefit more from the open alternatives in the long-run.

Now, let us move on to the best open-source ChatGPT alternatives.

Not all demos allow commercial use. You need to be careful when using the content from the chatbot demos for some options.
