We just launched @Dograh , the open-source alternative to Retell and Vapi for building voice agents.
Self-hostable, so you own your stack and your data.
We started it out of rage - every tool was too expensive, too closed, or scammy (addon after addons). So we open-sourced every line from day 0, on one belief: no company should own voice AI. Big labs are lobbying with govts to ban open source.
