Multi-tenant AI voice widget: paste one script tag, get bookings & chat
V.AWBS is a multi-tenant SaaS that lets any business add an AI voice assistant to their website with a single script tag — no coding required from the end customer. Built on Cloudflare Workers + D1 (serverless, globally distributed), with GPT-4o-mini + OpenAI TTS for the voice assistant, Stripe for billing, and Resend for email. How it works: business owner enters their website URL, the system crawls it automatically, and generates a ready-to-embed widget snippet within minutes. Key features: Guided onboarding with automatic site crawling Industry-specific AI prompts (dentist, lawyer, beautician, restaurant — easily extendable) Google Calendar and Calendly integration for real appointment booking Full dashboard: conversations, appointments, unanswered-question tracking Email fallback when the assistant can't answer Stripe billing already wired up (Free / Starter €29 / Pro €79 tiers) Documented security model (SECURITY.md): rate limiting, widget origin binding, CSRF-protected OAuth, 600k-iteration password hashing, SSRF guards Full production deploy runbook included — not just a local demo This is one of the more complete projects in terms of documentation and production-readiness among similar-stage SaaS tools: it ships with a real security threat model and a step-by-step go-live checklist, not just working code. Known pre-launch items (documented in SECURITY.md): encryption-at-rest for Google OAuth tokens, dashboard CSP headers, and monitoring setup are flagged as remaining before full production go-live. Asking price reflects source code sale only (no active clients, hosting, or brand included — Cloudflare Workers/D1 setup and API keys are not transferred and would need to be reconfigured by the buyer).
Project details
Next step: <p>The core product is functional end-to-end: onboarding, site crawling, AI voice widget, appointment booking, and billing are all wired up and documented with a real production deploy runbook. To take it fully to market, a buyer would want to:</p><p><br></p><p>- Complete the pre-launch security items already flagged in SECURITY.md: encryption-at-rest for Google OAuth tokens, CSP headers on the dashboard, and monitoring/alerting setup</p><p>- Expand the industry-specific prompt library beyond the current four verticals (dentist, lawyer, beautician, restaurant) to match their target market</p><p>- Set up their own Cloudflare account, API keys (OpenAI, Stripe, Resend, Google OAuth), and custom domain — none of these are transferred with the sale</p><p>- Add automated tests around the crawler and voice pipeline, since these are the most failure-prone parts of any AI-driven onboarding flow</p><p>- Consider a self-serve billing upgrade/downgrade flow, since Stripe checkout is wired up but the current tiers (Free/Starter/Pro) may need adjusting to the buyer's market</p><p><br></p><p>This is a strong fit for someone targeting local service businesses (dentists, salons, restaurants, law firms) who want a simple "paste one script tag" AI receptionist — a growing category with clear willingness to pay, especially in markets where 24/7 phone coverage is a real pain point.</p>
