Description
I built Cossistant as a lightweight, open-source alternative to Intercom/Zendesk for NextJS/React devs. You can embed it with a simple NPM command and under 10 lines of code.The goal was so far to be a very very good human to human support platform, the next goal is to enable AI agents to auto-handle 80% of queries (train on your docs and knowledge) and eventually escalate to humans when needed.Everything is customizable with Tailwind or your custom React components.Support tools are bloated, pricey and never FEEL / LOOK like your product, this is why it's being shipped as part of your stack and not coming from someone else's.It's already generally available!Feedback/debates are welcome, what's missing?

Could you build this?
Yes A lightweight embeddable React customer support widget backed by a standard chat backend (WebSockets or Supabase) is a quintessential vibe coding project.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
