Ask HN: I have an initial platform but not a product. Any SaaS ideas?

Recently in my spare time I've coded a small initial platform on AWS. I've set up IaC, CI/CD dev/prod, management (sso, billing alarms), frontend hosting, api, logging, tracing, database, auth etc. Since it is mostly serverless, I don't pay anything for it (because there is no product/usage). My idea was to use it to test some product ideas and maybe something will stick. Do you guys have any ideas for a SaaS product? I know there are probably a bunch of people in the same situation, but it won't hurt to ask. Thank you
