How much does it cost to build an app like TikTok?

It costs about 500-700K dollars to build an MVP of a TikTok-like app. This includes algorithmic video feed, effects, monetization options, video editing, etc. The price can be lower if you use premade SDKs (e.g. Banuba Video Editor SDK) instead of developing everything from scratch.
