Nice. Some ideas for the landing page:

- You don't have any use cases. Good technical explanations for sure, but generally people "get" a product better/faster with some examples of what it can do for them (instead of "hybrid reverse proxy" stuff).

- On the surface this seems similar to lot of other real time messaging services. Clear "why this over those" or unique selling points is missing.

- The free cloud plan seems really stingy.. 500 free messages per day is so low that it left negative impression.
