What does it cost to build an app like Zoom?
Sample range · freelance
$37k–$86k
An agency would be $67k–$189k for the same scope. This is a pre-computed sample, not your estimate. Your version is probably smaller.
Where the money goes
Why this kind of app is expensive
Live audio and video for multiple participants is real-time media infrastructure — a different discipline from a normal app, and it has to hold up on someone's bad hotel wifi.
Recording and transcribing every call at scale means storage, processing, and retention policy, not a save button.
Enterprise buyers require SSO and admin controls before rolling it out past one team, and calendar sync across providers is its own integration surface that breaks in new ways constantly.
The cheapest honest version of this idea is 1:1 calls only, no recording or transcription, no enterprise SSO. That lands nearer $24k–$57k.
