Zoom vs Whereby: could you build either?

The clearest split on the register: Whereby is a thin wrapper you can build, Zoom is global media infrastructure you can't. Same category, opposite verdicts, and the reason is worth reading.

These two split: Whereby is the more realistic rebuild, Zoom the one to think twice about. Whereby is a weekend of work against a rebuild that isn’t worth starting for Zoom. Zoom lists at $14.99/mo against $6.99/mo for Whereby — 2.1× the price, a difference of $96 a year.

Why Zoom gets 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

Why Whereby gets Borderline

  • A browser-based call room using an existing WebRTC SDK, with no app download required, is a bounded, well-documented integration
  • A persistent room link (same URL every time) is a simple, static routing pattern
  • For small-group calls (2-6 people), this is a genuine weekend project on top of the right SDK

Where the builds overlap

Both rebuilds are made of parts from the Vibe Codeability Database. The shared ones are work you'd do once either way — the split ones are what actually separates these two.

ONLY WHEREBY

Nothing — every part of this rebuild is also in Zoom.

What you lose leaving Zoom

  • 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

What you lose leaving Whereby

  • Reliable video quality across unpredictable networks and larger group sizes is the same real-time infrastructure challenge every video app on this register shares
  • Custom branding (waiting rooms, your own logo on the call screen) is real but bounded additional polish
  • Recording and cloud storage of calls adds real video-processing and storage scope

Questions

Is Zoom or Whereby easier to build yourself?

These two split: Whereby is the more realistic rebuild, Zoom the one to think twice about. Whereby is a weekend of work against a rebuild that isn’t worth starting for Zoom. Zoom lists at $14.99/mo against $6.99/mo for Whereby — 2.1× the price, a difference of $96 a year.

Can I build 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.

Can I build Whereby?

Borderline. A simpler case than Zoom's: no-download, browser-based video calls built on an existing WebRTC SDK are genuinely achievable for small groups, though real-time video infrastructure at any real scale remains the hard part.

What do Zoom and Whereby have in common technically?

Both rebuilds need landing page, live video / webrtc. That shared foundation is why they score similarly on the parts they overlap on — the difference comes from what each one adds on top.
