RunKit provides this functionality and it’s more or less instant (every version of every package on npm is already pre-installed, you won’t feel the boot up time, just the code in question’s actual execution time). Also, it’s free and has been free since it was introduced about 5 years ago. The code lives on your site so the “degraded experience” if we’re ever down is just “falljng back” to the unrunnable code. Try it yourself and see if the speed is acceptable: https://runkit.com/docs/embed https://runkit.com/docs/embed
