If cold starts are at all an issue for whatever use-case, you can just do a warming job like we do (in our case it's built into Ruby on Jets). We find invoking every 30 seconds is enough to never have a cold start. It's still quite cheap as well. The lambda portion of our bill (with tons of platform usage) is still incredibly low / low double digits.

Just doing a warming job with no other usage falls well within free tier usage, I can confirm.
