Should I charge for my product?

Hi Product Hunters! I built a no-code tool that gives people the ability to customize Vimeo videos without the need for a paid Vimeo Pro account (https://vimeoconfig.com/). I've posted it on many channels and it gets an average of 80 active users a month. I've played around with the idea of charging a lifetime fee to use it as it does provide value for developers and marketers who want a more minimal/custom look to displaying Vimeo videos. For me the project has been useful to experiment on how to launch a product and finding the channels that are valuable for getting exposure. I've ran no paid ads and have found that building organic traffic with basically 0 content for such a niche product like mine is difficult but possible. Options I'm considering to gain more knowledge about developing a product: - Charging a one time fee for people to use it? - Maybe get people to enter their email so I can start a related newsletter but still keep it free. - Write content about how to use the product for even more customisation to continue driving traffic. Any feedback is appreciated. Right now people know and use it and I have nothing really to lose if I start charging and people don't pay for it.
