The O'Saasy License
Hisaabo uses the O'Saasy License, a source-available license designed for sustainable open-source businesses. Here's what it means in plain English:
You can
- Use Hisaabo for your own business, free forever
- Self-host on your own servers
- Read, audit, and modify the source code
- Build internal tools on top of it
- Contribute improvements back to the project
You cannot
- Offer Hisaabo as a hosted service to third parties
- Sell a managed/SaaS version of the software
- Remove or obscure the license and attribution
The restriction is narrow: you cannot compete with our hosted offering by reselling Hisaabo as a service. Everything else is fair game. Read the full license explanation.
