Notes from building the tools on this site.
The Workers free plan allows 1,000 KV writes a day, shared by everyone. The rate limiting binding let 82 percent of a burst through, WAF rate limiting rules on a free zone are stuck at a 10 second window, and neither can express a daily cap. A per address Durable Object can.
Six shorteners, side by side, on the things that decide a free link: whether you have to sign up, how many links you get, whether you can pick the ending, whether you can take one down afterwards, and whether anything is counted. Two of the six will not let you delete a link you made.
The Workers free plan gives each invocation 10 ms of CPU, and an isolate tolerates going over as long as you do not do it often. I changed a cron from every ten minutes to every minute and it died an hour later. Then the profiler disagreed with all three of my guesses.
