We run silverbullet on teal, and it's a great piece of software. It's not ideal for us, however, as it doesn't support multiple users the best and we've had various sync conflicts/delays/etc. even with 1 user. We also don't need all of its features - for example it seems to be leaning heavily into offline mode which we don't need...
...insetad, mediawiki. It's heavier, uses wikitext rather than markdown, etc. but for collaborative features, history, etc. it far exceeds SilverBullet
