QA is a product feature
Exploratory testing, e2e suites and regression budgets — breaking things before your users do.
Read articleRealtime used to be a line item
For years, “live updates” meant websockets, a pub/sub layer and a week of edge cases. Clients paid extra for it, so most products shipped without it and relied on refresh buttons.
What a reactive backend changes
With Convex, queries are subscriptions by default. When data changes, every screen that depends on it updates — no cache invalidation code, no polling. That turns realtime from a feature into a property of the system.
The trade-offs
You accept a specific data model and a hosted runtime. For heavy analytics we still pair it with a warehouse. But for the operational core of a product, the speed of iteration wins every time.
What we promise now
Every product we ship is collaborative out of the box. Two people looking at the same record see the same thing, instantly. Clients stopped asking for it — they just expect it.
