Little Things

One of my favorite tools is ngrok (pronounced en-grok, presumably referencing Stranger in a Strange Land, a book I read as a freshman in high school when I was far too young to appreciate it). If you need to get a locally-running service on the Internet, ngrok can do it in seconds with a single command. I use it all the time when experimenting with and debugging APIs, such as this weekend’s foray into LangChain.

Supposedly it can do a bang-up job of fronting production services also, but I’ve never tried it for that use case. Perhaps someday? In any case, I’m truly grateful it exists.
