Fonoster
Fonoster is a self-hostable platform for building voice apps and AI voice agents that make and answer real phone calls, with PBX features and SDKs. It is for developers who want programmable phone calls without relying on a closed service, and it can also be used through Fonoster Cloud.

What we couldn't confirm3
- Whether SMS and video APIs are supported, since the README only describes voice features.
- Whether the Fonoster Cloud service has paid tiers or closed parts beyond the MIT-licensed code.
- Whether the project is stable for production use, given the README's warning about major upgrades and breaking changes.
