Cloudflare Workers sound cool, but their pricing is, to me, all wrong. I'd like to try them out on some of my low-volume side-projects to see if I'll find them useful and like them, but $5 per month per site is more than I pay for the entire server for all the sites combined.

I don't like being that guy who asks for free stuff, but a free tier would at least mean that I get to spend an hour or two trying the feature out. Not that $5 is a prohibitive cost, but Workers haven't sounded good enough to take my credit card out for.
