Scheduling and meetings decision
Whereby
A competent developer can build a usable browser-based conferencing replacement (embedding, rooms, chat, recordings) but reproducing Whereby’s certified compliance, globally distributed server mesh, uptime SLA, and enterprise support is expensive and time-consuming, so paying is reasonable for production-critical or enterprise use.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Whereby alternatives, with the arithmetic →
Code Whereby publishes itself
Not a way out of the subscription - these are the vendor’s own repositories. Worth a look for how they build, and for anything you would have to integrate with.
What a replacement has to do
- Start/join browser WebRTC calls, host rooms with persistent URLs, share video/audio/screen/chat, optionally record and transcribe sessions.
What it still won’t have
- Globally distributed server mesh and bandwidth-optimized routing across regions
- Enterprise SLAs (99.9% uptime) and large-scale reliability guarantees
- Official compliance certifications (GDPR/HIPAA configuration and ISO 27001 certification)
- Mobile SDKs and embeddable pre-built UI with maintained docs and developer support
- Dedicated customer success and enterprise-level support included
What remains hard
- Compliance and regulation
Built in Europe, our products are GDPR and HIPAA compliant, and ISO 27001 certified.
- Infrastructure at scale
Globally distributed server mesh
- Execution quality
Unrivaled support From our developer docs to our dedicated Success team, we’re here to help. At no extra cost.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted WebRTC conferencing service using React for the web UI, Node.js + Express for signaling, Janus or mediasoup as the SFU, Coturn for TURN/STUN, Postgres for room metadata, and S3-compatible storage for recordings. In scope: persistent room URLs, join/create UI, basic in-call controls (mute/camera/screenshare/chat), server-side cloud recording saved to S3, and optional speech-to-text via a third-party API. Out of scope: achieving ISO 27001/HIPAA certification, multi-region global mesh, mobile native SDKs, and enterprise SLA. Include authentication for locked rooms, webhooks for events, error handling, and automated unit/integration tests for signaling and recording flows.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
