About Open-Source

The open-source model has been known for a long time, but many investors are still skeptical about it. This model is not so much different from SaaS – often the community version acts as a freemium that can be deployed in your cloud, and the enterprise version has a large set of features that you already need to pay for. But the main difference between open-source and SaaS is that open-source can be deployed in an internal cloud without sharing user data with 3rd parties.

More and more open-source startups are taking advantage of this trend and creating analogs of well-known SaaS products. It’s simple: the demand for these services has already been confirmed by the market, but there are niches where the SaaS model does not fit โ€” that’s where open-source analogs are aiming.

About SaaS

The SaaS model is the default model for almost all companies that make

money online. But it wasn’t always like that. Before the dot-com era, the most common model was on-premises, when users paid for a license and installed software directly on their device or a server. With the advent of SaaS, this model was forgotten, but, as we know, history is developing in a spiral.

Recently, the issue of personal data and state regulation in this area has been increasingly raised. Some companies simply cannot use popular cloud products (for example, Google Analytics) because they are forced to share user data with 3rd parties. There is a new market segment that is not suitable for SaaS.
