Looks great on first look, but on closer inspection saw that it's written in pure JavaScript (0% TypeScript) + Bash. Honestly makes me a bit worried about security. Now, I'm not so thrilled about it anymore...
Judging the security of an application based on its use of typescript is like when people judge the intelligence of a person depending on if they have an English or an American accent.
While we're doing analogies: I don't think it's like judging someone's intelligence from their accent. It's more like betting (or not) on the Jamaican bobsleigh team for an olympic medal. -- Certain programming languages invite buggy code more than others. Certain countries are a better environment than others for winter sports.
