ngrok
Free plan for putting a local app online: $5 of one-time included usage, up to 3 online endpoints.
Dev Tools
What you get
Public URLs for local apps, webhooks and demos on an assigned dev domain: up to 3 endpoints, 1GB transfer and 20k HTTP/S requests from a one-time $5 credit.
How to get it

What it requires
Not stated on the pricing page.
The catch
The $5 is one-time, not monthly, and there's no usage beyond it. Visitors see an interstitial page on HTTP/S endpoints. Random TCP addresses need card verification. Hobbyist is $10 a month.
