Every vibe coder hits the same wall

You built a beautiful app. Now your users want it to actually do something.

"I built my app in Lovable but I have no idea how to connect it to Gmail or QuickBooks."

— r/vibecoding

"Every tutorial assumes I know what a webhook is. I don't. I just want my app to work."

— r/nocode

"Zapier works for me personally, but I can't embed it into a product I sell to my own customers."

— r/SaaS

"I want to charge $99/month but the app doesn't actually automate anything yet. The backend is missing."

— r/microsaas

"I hardcoded my API key in the frontend and now I'm scared to show it to real users."

— r/vibecoding

"The AI generates a perfect UI but I have no idea what to put in the API call section."

How It Works

From idea to working app in three steps

No backend experience needed. No setup headaches. Just describe what you want.

Tell us what your app does

Describe your app idea in plain English — what should it read, write, or automate? What tools does it need to connect to? We'll handle the rest.

We design your backend

Our AI builds a production-ready automation pipeline with the right connections for your use case. Gmail, Stripe, Salesforce, QuickBooks — all wired up securely.

Paste a prompt into Lovable

We generate the exact Lovable prompt your frontend needs. Copy it, paste it, and your app now has a real working backend. Ship this week.

What You Get

Everything your app needs to actually work

Sinos handles the complexity. You focus on your product and your customers.

Connect to any app your users use

Gmail, Slack, HubSpot, Salesforce, QuickBooks, Stripe, Airtable, Notion, and 250+ more. Your users connect their own accounts — no passwords stored, no security nightmares.

AI that reads, writes, and reasons

Add intelligent steps to your pipeline — summarize documents, extract data, draft emails, score leads, or make decisions based on your users' data. Powered by the best AI models available.

Runs in the background

Long-running automations that take minutes or hours run silently in the background while your users do other things. Your app stays fast. Results come back when they're ready.

See exactly what's happening

Every run is logged — what ran, how long it took, what it cost, whether it succeeded. You get a complete picture of your product's health without building any analytics infrastructure.

One API key, fully secure

One builder API key connects your app to Sinos. Your users' credentials are stored securely on the server — never exposed in your frontend code. No security expertise required.

Lovable prompt, ready to paste

After designing your pipeline, we generate the exact prompt you paste into Lovable or Bolt to wire up your frontend. No guessing what the API call should look like.

Integrations

Connect to the tools your users already use

If your app needs to touch it, Sinos can connect to it — no code required.

📧 Gmail 💬 Slack 💰 Stripe 📚 QuickBooks ☁️ Salesforce 📋 HubSpot 🗓️ Google Calendar 📊 Google Sheets 🗂️ Airtable 📝 Notion 🔺 LinkedIn 📦 Shopify 📮 Outlook ✅ Asana 🎫 Zendesk

+ 235 more apps. If your users use it, we connect to it.

Why Sinos

Zapier is for you. Sinos is for your users.

There's a big difference between automating your own work and building automations into a product you sell.

Zapier / Make

❌Personal automation tool — your workflows, not your customers'

❌Can't be embedded inside a SaaS product you sell

❌Your users can't trigger Zapier flows from your app

❌No per-user billing or metering built in

❌Requires you to set up every workflow yourself

Sinos

✅Runs inside your product — your users trigger their own automations

✅Built to be embedded in apps you build and sell

✅Each user connects their own accounts securely

✅Simple per-run credit pricing — know exactly what you spend

✅AI designs the pipeline — you just describe what you need

Integration

One API call from your Lovable app

Drop this into any app that supports custom API calls — Lovable, Bolt, Replit, or anything else.

// Run a Sinos pipeline from your Lovable / Bolt / Replit app
const response = await fetch('https://api.sinos.pro/run-pipeline', {
  method: 'POST',
  headers: {
    'x-api-key': SINOS_API_KEY,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    pipeline_id: 'your-pipeline-id',
    user_id: currentUser.id,
    variables: { /* whatever your pipeline needs */ }
  })
});

// Sinos handles: connections, AI steps, retries, logging
const { run_id, status, creditsRemaining } = await response.json();
