Can I code Zoom?

Scheduling a call and putting a join button on a page is the easy 10%. Real-time, low-latency video across unpredictable networks — the actual hard problem — is a specialist field most companies rent rather than build, including companies much bigger than a solo project.

how this is worked out

Why CanICodeThis says Just pay

  • The scheduling, invite, and waiting-room UI around a call is ordinary web development
  • For a two-person call, existing peer-to-peer WebRTC libraries can get you a working prototype quickly
  • It's worth being honest about where the line actually is: everything up to 'connect two browsers' is buildable, everything after that isn't

Read before building

  • Reliable multi-party video at scale — mixing, adapting to bad connections, working behind restrictive corporate NATs — is deep, ongoing infrastructure work, not a library you drop in
  • Recording, transcription, and cloud storage of calls is a second full product on top of the video itself
  • Enterprise reliability (a call that just works, every time, for a wedding or a board meeting) is the entire reason people pay

The build spec

Don't rebuild Zoom's video infrastructure. Build the part around it instead: a scheduling and join-link page (OAuth to your calendar, generates a unique room link per meeting) that hands off to an existing WebRTC video SDK for the actual call — treat video transport as a service you integrate, not something you build. Waiting room, mute/camera controls, and a simple chat sidebar are all reasonable to build yourself on top of that.

Questions

Can I code Zoom?

Just pay. Scheduling a call and putting a join button on a page is the easy 10%. Real-time, low-latency video across unpredictable networks — the actual hard problem — is a specialist field most companies rent rather than build, including companies much bigger than a solo project.

How much does Zoom cost?

Zoom costs $14.99/mo (about $180/yr) as of 2026-08. That's what a working rebuild would save you.

What do I lose by building it myself?

Reliable multi-party video at scale — mixing, adapting to bad connections, working behind restrictive corporate NATs — is deep, ongoing infrastructure work, not a library you drop in Recording, transcription, and cloud storage of calls is a second full product on top of the video itself Enterprise reliability (a call that just works, every time, for a wedding or a board meeting) is the entire reason people pay

Is there a free alternative to Zoom I don't have to build?

Yes — Jitsi Meet are open-source options worth trying before you build your own. Details are in the standard parts section on this sheet.
