What does it cost to build an app like Twitch?
Sample range · freelance
$41k–$95k
An agency would be $74k–$200k 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 video ingest with low enough latency that chat feels synced to the stream is a genuinely hard real-time media problem, distinct from on-demand video.
A chat system running alongside a live stream has to handle bursts of thousands of messages a second without falling behind.
Monetization means a creator payout system running in parallel with viewer billing, and clip and VOD storage at platform scale is an ongoing transcoding cost per hour streamed, not a one-time archive.
The cheapest honest version of this idea is pre-recorded video only, no live ingest, no subscriptions or payouts at launch. That lands nearer $22k–$51k.
