- Release as open source if that was your intent or you want it (feel like) to be open sourced

- If you strictly made it to make money, then release it as a paid product but assume it might not make any money at all or that it will take time to make money. I believe that there's a general advice to shut down a project that doesn't make money in a very short time but some projects take awhile to gain traction. You can also use this as a learning experience in marketing/sales. Play around with the pricing over time (starting with much lower rates than you'd planned for) and see what works. You'll learn from it.

- Another option is to shut down the project entirely. You still have your code and they might come in handy when you work on other projects in the future (this has happened to me with multiple side projects)
