Built for developers, loved by finance teams
At $0.015 per SMS vs Vonage's $0.05, you'll save thousands annually. A startup sending 10,000 OTPs/month saves $4,200/year—that's a full-time developer's salary in many regions.
Vonage only does SMS. We support Email ($0.0025), SMS ($0.015), and WhatsApp ($0.006) with automatic fallback. One API call handles all channels intelligently.
Just 2 API calls: /otp/generate and /otp/verify. No complex SDKs or workflow management. Most teams migrate in under an hour.
Beyond OTP, you get a complete messaging platform. Send transactional emails, marketing campaigns, and notifications—all from one dashboard. Consolidate your tools and save even more.
Most teams complete the switch in under an hour. Zero downtime required.

4. Get your API key instantly
5. Start sending (100 free SMS included)The API is intentionally simpler than Vonage. Here's a side-by-side comparison:
// Generate OTP
const { Vonage } = require('@vonage/server-sdk');
const vonage = new Vonage({
apiKey: API_KEY,
apiSecret: API_SECRET
});
vonage.verify.request({
number: '1234567890',
brand: 'YourBrand',
code_length: 6
}, (err, result) => {
const requestId = result.request_id;
});
// Verify OTP
vonage.verify.check({
request_id: requestId,
code: userCode
}, (err, result) => {
if (result.status == '0') {
// Success
}
});// Generate OTP
const response = await fetch(
'https://api.sendmator.com/v1/otp/generate',
{
method: 'POST',
headers: {
'Authorization': `Bearer ${API_KEY}`,
'Content-Type': 'application/json'
},
body: JSON.stringify({
phone: '+1234567890',
channel: 'sms' // or 'email', 'whatsapp'
})
}
);
const { verification_id } = await response.json();
// Verify OTP
const verify = await fetch(
'https://api.sendmator.com/v1/otp/verify',
{
method: 'POST',
body: JSON.stringify({
verification_id,
code: userCode
})
}
);
const { verified } = await verify.json();
Pro Tip: Use our multi-channel fallback by setting fallback_channels: ['email', 'whatsapp']. If SMS fails, we'll automatically try email, then WhatsApp.
Use our sandbox mode for testing, then run both systems in parallel before fully switching.
