Lark

Team Communication · Free · since 2019

Lark is a integrated workspace combining messaging, video, docs, and project management from ByteDance. It handles messenger, video, docs, and calendar, and it's best suited for teams wanting an all-in-one collaboration suite. It has been around since 2019, giving it a 7-year head start in building out integrations and refining the product.

The free plan is free for up to 50 users — enough for most people to evaluate whether it fits.

Notification overload is a real problem as the number of channels grows
Mobile experience lags behind the desktop version in features and polish
