Mine is an online animation editor that requires no coding or formulas https://toonclip.com The first users came from a post here on HN and Product hunt. For community building we have a Forum and a Discord server. Also our animations can be exported and shared on social media. As these animations have the ToonClip log,o it drives a decent bit of traffic. - Source: Hacker News / almost 3 years ago

I am still in this process. My first launch was here on Hacker News, but at that time it was a prototype with no way to register and log in. Interest was very good. Then launched on Product Hunt where I got my first 20 registered users. Beyond that it has been posting the animations created on 4chan and other social websites.

I guess since the last promotion I've mostly just provided comments to (powerpoint) presentations of others rather than having to create one myself. It's been so long since then that I wouldn't be able to recall what my setup even is at this point, but I believe I did research and chose sli.dev in the end. I wish I could share more, alas, my notes from those times are laughable. Source: over 1 year ago

Seeing that you use Marp, did you take a look at https://sli.dev yet? I've switched to that from Marp and it's been pretty great! I've held my Bachelor's colloquium and a 100+ min presentation at work with it and it was fantastic! Source: over 1 year ago
