The voice-agent SaaS layer 22 of 25 open-source repos basically skip

We went through 25 voice-agent repos and scored them properly. Multi-tenancy, phone provisioning, billing, GDPR. Honestly? Almost none pass. Callforge is the stuff they're missing. Packaged up so you don't have to build it.

When the tutorial ends, you're kinda on your own.

Voice agent repos are great at proving the agent can talk. That's it. They skip the messy SaaS bits every real product needs:

One phone number per customer — not some shared line that leaks data
Per-minute billing wired to actual call durations, not flat monthly seats that don't match usage
GDPR-safe recordings — consent gates, per-tenant storage, proper erasure hooks

Look, these take 3–6 weeks to build properly. We've done it three times for different clients. Got sick of rebuilding the same mess. So we packaged it.

Callforge is the multi-tenant layer for voice-agent SaaS.

Built on Next.js + Twilio + Vapi + Stripe. Deploy in a weekend if you know what you're doing. Ship your first paying tenant in a day.

What you get vs what it replaces

What you get

What it replaces

One API call. You get a real number, Vapi assistant, and Stripe subscription per tenant. Done.

3–4 weeks of provisioning plumbing you'll mess up twice

Per-minute billing via Twilio call-status webhooks that actually sync to Stripe metered usage

Custom billing logic + those fun reconciliation headaches at month-end

GDPR consent gate, per-tenant recording buckets, erasure webhooks ready to go

Legal review bills and a bespoke compliance build that'll break in six months

Missed call triggers SMS triggers human approval flow. Leads don't get lost.

Lost revenue while your agent doesn't pick up and nobody notices
