Here's my personal list of things I want to see on Val Town. I may build them myself at some point, but to the glory goes the person who builds it first. If you want to collaborate or get clarification on any of these ideas, please drop me a comment or reach out on discord.

Possibly the singular most popular thing to do on Val Town is to build a downtime detector for your website. This one from @healeycodes is super popular as well as this fork by @andreterron.

Sites like cronitor do this and also seamlessly provide a status page as well, for example like this one: https://status.val.town/.

It would be awesome if we built a fork of these downtime detectors that also stored historical uptime/downtime (and possibly latency) information in sqlite, and then provided an http interface to view the data as well.

I have been working on a stock price api tool, initially for use within Google Sheets: https://www.val.town/v/stevekrouse/stockPrice

It would be awesome to expand this to also be useful to other folks, ie folks within Val Town. For example, it could be used to build stock price trackers. Our BTC price tracker is pretty popular. I think one for stocks would be similarly popular, but it'd need someone to provide a good free stock API. Maybe one exists or maybe we need to proxy it.
