Backend-as-a-Service

Auth, email, payments, and messaging — as a service.

One API for the backend services every SaaS needs. TypeScript and Python SDKs. Start free or scale with managed plans.

No Clerk. No Resend. No assembling 5 different services. One SDK, one bill.

Ship in minutes, not weeks

Install the SDK. Register users. Send emails. Accept payments. All through one client.

app.ts
import { BuildvoxClient } from '@buildvox/sdk';

const client = new BuildvoxClient({
  projectId: 'proj_abc123',
  apiKey:    'sk_live_...',
});

// Register a user (verification email sent automatically)
const user = await client.auth.register({
  email: 'alice@example.com',
  password: 'securepassword',
  name: 'Alice',
});

// Send a transactional email
await client.email.send({
  to: 'alice@example.com',
  subject: 'Welcome!',
  html: '<h1>Welcome to our app</h1>',
});

// Create a Stripe checkout
const checkout = await client.payments.createCheckout({
  externalUserId: user.id,
  mode: 'subscription',
});

Your entire backend, one dashboard

Monitor all services, manage API keys, and track usage from a single console.

How it works

01

Connect

Create a project. Get your API key. Install the TypeScript or Python SDK. One import, one constructor call.

02

Integrate

Call client.auth.register(), client.email.send(), client.payments.createCheckout(). Your backend services are ready.

03

Ship

Focus on your product, not backend infrastructure. Scale with confidence — upgrade your tier as you grow.

Battle-tested in production

We built Kubevox and Jobvox on Buildvox. Two real SaaS products, running in production, powered by the same platform you'll use.

Kubevox

Kubernetes portfolio orchestration. Uses Buildvox for auth, email, and notifications.

Jobvox

AI-powered job discovery. Uses Buildvox for auth, email, payments, and notifications.

Stop assembling services

Most developers pay $70-180/mo assembling auth + email + payments from separate vendors. Buildvox bundles everything.
