Replace expensive per-seat SaaS with tap-to-install open-source apps

The App Store for
Open Source

Liberate your data by replacing expensive SaaS with tap-to-install open-source applications. Instead of corporate data silos with high switching costs and vendor lock-in, use curated open-source tools that offer you complete control over your data and privacy.

What do you get when you self-host open-source applications via Fortressa?

Unparalleled ROI

Software-as-a-service is often charged on a per-seat basis, so even small 50-person companies can easily spend thousands each month on just a handful of SaaS products. Fortressa provides open-source alternatives for a tiny fraction of the cost, yielding unparalleled return on investment without having to worry about costs skyrocketing as you grow.

No Vendor Lock-In

Proprietary SaaS has a vested interest in making it difficult for you to take your business elsewhere. They do this by restricting access to the data you have put into their products — data that is rightfully yours and yet is locked away out-of-reach. Fortressa takes the exact opposite approach: all of your data is fully available to you from day one — without even having to ask for it.

You Own Your Data

Many companies have problematic business models that mine your personal data and sell it to the highest bidder. Fortressa considers privacy to be its most important core value, so neither we nor any other third-party company or platform can spy on the data associated with your open-source applications.


When you think about the apps and SaaS products you use, do you ever wish you could change how they work? Add a feature you really need? While that isn’t possible with most proprietary products, open source provides you with the freedom to customize how your software works, making it work for you — not the other way around.

The per-user pricing model used by many software companies can get expensive… fast. We believe all members of your team should have the best tools, so Fortressa doesn’t use per-user pricing.
