Most of the CRM software is web-based. There are some free open source ones like EspoCRM. Some companies shy away from them because they require IT skills, monitoring, maintenance, backups, which are hassle or expensive for small companies.

If you're a solo CRM user or a small company with a few users, would you use a free desktop CRM software if it were as easy to install as any desktop app? If you're the only user, the app and the database will be on your computer. If you were a company, each user will have it installed on their work computer. The database can be hosted anywhere. A computer in the company with no hosting fees, or hosted in the cloud (Azure or AWS) or hosted at a hosting company with as little as $5 for shared hosting with backups. This option will be Windows only, so no Mac or Linux.

There will also be a web based version with the same features.

But I am inquiring right now about if there's interest in the desktop version if it means it's hassle-free to install, host and use. It's free as well.

The business model is making money from advanced customizations.
