we have generated over 1 million in revenue for a client in US using 1 voice agent on livekit (case study + client interview coming soon) now why i tell you this is because to show that we dont play around with toy bots and build extremely reliable voice agents on livekit that are killers in production. we built our own voice ai stack on top of livekit, next js, supabase and hosting servers on digital ocean. soon we will open source the entire code and currently looking for agency owners to try out the platform and give us rapid feedback so we can fix bugs before open souring the entire code for public access. the stack does not just include UI that looks like vapi/retell , it has many other parts like call concurrency management server, livekit manager server that gives you api routes to easily start calls, receive end call reports and much more. our goal with this open source project is to completely replace vapi/retell + cekura + chatdash and have one stop shop for voice ai devs to build and deploy agents for clients. here are some internal docs and diagrams that give you overview of the voice ai stack we have built that we use for our clients https://github.com/VocalGrid/diagrams comment below if interested (please do not DM me)
