Hi all, founder @ Retool here. We've made a lot of progress over the past few years, but we first started on HN, and certainly wouldn't be here without all of you! For example, here's when we launched: https://news.ycombinator.com/item?id=14515494 . Hilariously, we described Retool as "Excel with higher order primitives", and people understood it! (Only on HN!) After that, we spent around a year polishing the product…
Hopefully this is something money can fix :)
the problem was the sum of UI latency to US(?) plus latency of serial API calls to get the data. We could probably have lived with a full rendering time of 100ms or so, but responsiveness requirements don’t scale linearly. So with a few round trips, it quickly became insurmountable.
