I'm interested in pursuing a few new concepts, and I'm looking for the best free resources for startups that aren't going through an incubator. Specifically looking for free tier or startup credits beyond what AWS / DO / GCP has to offer, or for off-the-beaten-path programs that single-founder startups might be able to take advantage of. I'll be using Stripe for processing any payments.
What do you folks use when you're looking to stand up your MVPs?
