Good fit for Engineering teams that want session replay as a primitive they own end-to-end and don't need a fancy product UI.
Weak at Bring your own everything — no analytics, no heatmaps, no admin UI; this is a library, not a product.

Replaces these SaaS
- FullStory · Session replay + product analytics
rrweb is the recording library at the heart of OpenReplay/PostHog/Hotjar. Install via `npm install rrweb`, hook `rrweb.record({ emit: events => POST(events) })` in your app, store the event stream (S3, Postgres JSONB), and replay via `new rrweb.Replayer(events)`. You build your own UI on top.
