Make money online: YES

Building a SaaS can be a remote-friendly side hustle that allows you to work from anywhere as long as you have an internet connection. There are typically no hidden in-person requirements, and you can manage the development and operations online. On forums like Reddit and Twitter, many individuals attest to the flexibility and convenience of running a SaaS remotely. The success of this side hustle may depend on your location in terms of access to potential clients, time zones for communication, and the equipment needed for development. It's important to note that setting up a SaaS can range from $500 to $5,000, and the time to profit can vary but usually ranges from 6 months to 1 year. Potential red flags include fierce competition in the SaaS market and the need for ongoing maintenance and updates to stay relevant.
