Ship in minutes, not weeks

Install the SDK. Register users. Send emails. Notify and message them. All through one client.

app.ts
import { BuildvoxClient } from '@nimvox/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: '[email protected]',
  password: 'securepassword',
  name: 'Alice',
});

// Send a transactional email
await client.email.send({
  to: '[email protected]',
  subject: 'Welcome!',
  html: '<h1>Welcome to our app</h1>',
});

// Notify a user in-app
await client.notifications.send({
  userId: user.id,
  title: 'Welcome aboard',
  body: 'Your account is ready.',
});

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.notifications.send(), client.messaging.send(). 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 build our own products on it — Kubevox, Jobvox and Scoutvox. Real SaaS products, running in production, on the same platform you'll use.

Kubevox

Kubernetes portfolio orchestration. Decide what is safe to autoscale at all, then scale only what you approved.

Jobvox

Smart job discovery. Scan company career pages and rank every opening against your resume.

Scoutvox

Hiring intelligence for employers. Score job-listing quality, benchmark against the market, and rewrite with AI.

Stop assembling services

Most developers assemble auth, email and notifications from three separate vendors — three bills, three dashboards, three SDKs to keep in sync. 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, notifications, secure messaging and signed webhooks through a single API. Instead of wiring together Clerk, Resend, 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, in-app notifications, encrypted messaging, and signed webhooks. 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 emails per month and 60 requests per minute, with a generous fair-use ceiling on registered users. 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.
Do you charge per user?
No. Plans are a flat monthly price — we do not bill per user or per monthly active user, so your cost does not move when your signups do. There is a generous fair-use ceiling on registered users per project, set far above real use; if you are approaching it, talk to us.
Is my data secure?
All data is encrypted at rest and in transit. Secure messaging uses AES-256-GCM encryption, and every project is isolated from every other.
Can I self-host Buildvox?
Enterprise customers can request a self-hosted deployment. Contact us for details.
