Facebook & YouTube Creator SaaS

I am building a cloud-hosted, WordPress-based SaaS that lets creators spin up their own “mini Facebook/YouTube” spaces—complete with RTMP live-streaming, IRC-style realtime chat, and a tightly integrated video-editing studio. The core of the project is content creation, so everything from account signup to final publish should keep creators in flow: record or upload, trim, add overlays, then push the finished video straight to a channel that feels like a mash-up of Facebook feeds and YouTube TV.

Key requirements
• Front-end and back-end must run as a multi-tenant WordPress installation so each customer gets a branded sub-site.
• RTMP ingest and playback need to scale; I’m open to Nginx-RTMP, Ant Media, or another proven stack if it stays inside my hosting carrier’s environment.
• Real-time chat should follow an IRC protocol or modern equivalent and appear alongside the live player.
• The video-editing suite can be based on an existing JS library or custom Gutenberg blocks, as long as creators can cut, merge, and add simple effects in-browser.
• Cloned social features: follow/subscribe, threaded comments, reactions, and algorithmic or chronological feeds that mirror what users expect from Facebook and YouTube.
• Single sign-on across all modules and clean mobile responsiveness are non-negotiable.

Acceptance criteria
– A new tenant can be created from the WP network dashboard and goes live with default branding in under one minute.
– A test stream pushed via OBS appears in the tenant’s feed with chat active and playback under three seconds latency.
– A sample 1080p upload is editable and publishable without leaving the browser.
– Core social actions (like, comment, follow, react) work end-to-end for registered users.
– Source code and deployment docs are handed over in a Git repo.

If these checkpoints make sense, let’s talk through architecture choices and a milestone schedule so we can launch the beta quickly.
