Audio and podcasting decision
Riverside
A technical user can reproduce a useful subset (recording, separate-track uploads, transcripts, and a text-based editor) within a few weeks, but Riverside’s enterprise-grade scaling, compliance (SOC2/ISO27001), and broad integrations are durable advantages that are expensive to replicate.

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.
What a replacement has to do
- Record multi-track audio/video -> upload/store separate tracks -> generate transcript -> text-based edit (cut/copy/paste) -> export MP4/WAV
What it still won’t have
- Ability to reliably scale live webinars to ~10,000 viewers
- SOC2 / ISO27001 compliance and audit-ready controls
- Deep integrations (HubSpot, Salesforce, Marketo) and single-sign-on (SSO)
- Polished, production-grade AI features and at-scale media processing pipeline
- Unlimited hosted storage and enterprise-level reliability/SLAs
What remains hard
- Compliance and regulation
SOC2 & ISO27001 compliance
- Infrastructure at scale
Up to 10,000 webinar registrants

Runnable build prompt
Build a self-hosted minimal Riverside-like service using React (browser recorder + edit UI), Node.js/Express backend, Postgres for metadata, and S3-compatible object storage. Implement: (1) a browser client that records separate local tracks (audio/video) and uploads them; (2) server endpoints to store uploads and metadata; (3) an automatic transcription step using a cloud ASR or an open-source model and store aligned transcripts; (4) a text-based editor UI that maps transcript edits to media time ranges and can export stitched MP4 and WAV; (5) basic audio cleanup (noise gate/denoise) prior to export. Out of scope: live multistreaming to social platforms, enterprise SSO, SOC2/ISO certification, multi-tenant studio management, and editor collaboration. Include error handling for failed uploads/transcodes, retry logic, and unit/integration tests for recorder upload, transcript generation, and export functionality.

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.
