Can I code Whereby?

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.

VIBE SCORE 67/100

how this is worked out

Why CanICodeThis says 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

Read before building

  • 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

The build spec

Build me a simple browser-based video call tool: a persistent room link, no download required, built on an existing WebRTC SDK, supporting small groups. Basic mute/camera controls. Skip recording and custom branding for v1 — a clean, working call room is the real goal.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$43–$86 one-time
Hosting, once it's running$15–$30/mo
Domain name, if you want your own~$12/yr

Whereby costs $6.99/mo, but hosting alone could run $15–$30/mo — that can eat the whole subscription saving before the agent cost even comes into it.

Questions

Can I code 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.

How much does Whereby cost?

Whereby costs $6.99/mo (about $84/yr) as of 2026-08. That's what a working rebuild would save you.

What do I lose by building it myself?

Is there a free alternative to Whereby 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 page.
