Self-hosting means connecting your own provider accounts. The provider list below is based on the current codebase and .env.example.

​
Required for live calls

Convex stores business data, call records, contacts, appointments, knowledge, billing state, and app settings. It also runs backend functions and HTTP endpoints used by Twilio, the voice gateway, calendar callbacks, and downloads.Configure CONVEX_URL, CONVEX_SITE_URL, and matching VITE_ variables for the web dashboard.
Twilio provides phone numbers, inbound voice webhooks, Media Streams, SMS delivery, and phone verification.Live voice requires a Twilio number with its voice webhook pointing at the voice gateway. Onboarding phone verification requires TWILIO_VERIFY_SERVICE_SID.
OpenAI powers live voice conversations through the Realtime API. Configure OPENAI_API_KEY on the voice gateway.You pay OpenAI directly for self-hosted usage.
The voice gateway is a Node.js service with a public HTTPS URL. Twilio must be able to reach it for inbound calls and media streams.The existing deployment docs use Fly.io as one supported hosting option.

​
Optional providers

Google Calendar enables calendar availability and booking sync. Configure Google OAuth variables and SESSION_ENCRYPTION_KEY.
Firecrawl powers website knowledge import. Without it, operators can still add text entries and upload documents.
Gemini is used for embeddings and non-realtime text generation in knowledge and SMS flows.
Resend sends password reset and email-change emails. Without email delivery, those auth flows will not work correctly in production.
Polar powers hosted subscription billing, checkout, customer portal access, product mapping, transactions, and usage sync. Single-business self-host deployments usually do not need Polar.
PostHog is used for analytics and telemetry when configured.
