Building no-code Free Tools for Marketing?

Building no-code free tools is an effective marketing tactic for my Saas. It takes us normally just 15-30 minutes per tool, but every time we launch a new free tool for our target audience, there is a spike in traffic to our website. I'm still finding ways to do this more effectively, maybe a way to distribute these free tools other than ProductHunt. Have you considered experimenting with this marketing strategy for your Saas? Or have you done it successfully? Please share your experience here! Let me know if you have any questions.
