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',
});

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

Smart 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.

Frequently asked questions

Everything you need to know about Buildvox.

What is Buildvox?
Buildvox is a Backend-as-a-Service platform that gives you auth, email, payments, notifications, and secure messaging through a single API. Instead of wiring together Clerk, Resend, Stripe, and others, you get one SDK and one bill.
How is this different from Firebase or Supabase?
Firebase and Supabase are databases with bolt-on features. Buildvox is purpose-built for the backend services every SaaS needs: auth with OAuth, transactional email with templates, payment processing with Stripe and PayPal, in-app notifications, and encrypted messaging. We are opinionated about the SaaS stack so you do not have to be.
Can I use the free tier in production?
Yes. The free tier includes 1 project, 500 users, and 500 emails per month. It is production-ready with no time limit. Upgrade when you need more capacity.
What SDKs are available?
TypeScript and Python SDKs are available today. Both wrap the same REST API, so you can use any HTTP client if you prefer.
How does billing work?
We accept Stripe and PayPal. Plans are billed monthly. You can upgrade, downgrade, or cancel at any time from your dashboard.
Is my data secure?
All data is encrypted at rest and in transit. Secure messaging uses AES-256-GCM encryption. We run on hardened infrastructure with regular security audits.
Can I self-host Buildvox?
Enterprise customers can request a self-hosted deployment. Contact us for details.
