I frequently found myself needing to convert video files and everything is either paid, needs login, full of ads, or uploads your files. So I built my own tool that has none of that.
Yes, exactly why I built this. Works surprisingly well for my use case so far which is cutting ~300MB mov screen recordings down to size and converting them to mp4. That said, converting large videos to GIFs will almost certainly run out of memory.
The ease of getting things set up quickly and usually for free when starting up is very tempting. Later, migration is usually considered risky and not worth it because of maintenance overhead - which I would argue has become very easy.
I am working on https://spatialsheets.com Think geodata formulas + excel. Mostly for my own use just to quickly debug geodata. Used to heavily use geojson.io for it but it is not very good at handling large datasets and couldn't enrich data so I started working on this thing.
