WAservix vs UltraMsg: An UltraMsg Alternative With Lower Prices and More Numbers

If you're using UltraMsg, you already understand the idea behind WAservix: scan a QR code, get an API, send without per-message fees. So the search for an UltraMsg alternative is usually about one thing, the price, and sometimes about needing more than one number. UltraMsg lists $39 a month. WAservix, which we make, starts at $4.50 and includes campaigns and auto-replies on every plan.

That's almost nine times less for a broadly similar connection. We'll go through what's the same, what's different and the few cases where staying put is the smarter call.

Plan comparison#

UltraMsg's numbers come from its website, checked on 30 October 2026.

Why teams look for an UltraMsg alternative#

Mostly because $39 is a strange price for a small business. It's too much for a one-person shop sending a few hundred messages, and it adds up quickly for anyone with several numbers. At five numbers you're looking at $195 a month if each one is its own instance. On WAservix Plus, six numbers cost $22.

Agencies feel this most. If you look after WhatsApp for fifteen clients, per-instance pricing eats your margin, whereas a shared plan lets you treat it as a small overhead. We wrote the plans with that in mind.

The second reason is tools. A lot of people who buy a QR API don't want to write code. They want to upload a list and press send. WAservix has that as part of the dashboard, as well as auto-replies for common questions.

What UltraMsg does well#

Credit where it's due. UltraMsg has been around for a while and has a straightforward developer experience. It keeps things simple: an instance, a token and a clear set of calls. It's easy to find examples for it in many languages, and that counts for a lot when you're trying to get something working late at night.

It's also open about limits. Its site warns that WhatsApp may apply restrictions based on behaviour, and that bulk messages marked as spam can get a number blocked. Good. Every provider should say that plainly.

Its free three-day trial is another small win over our $1 trial. If you've got a working UltraMsg integration, you've also got no pressing reason to rewrite it just to save money on a single number, unless the saving matters to you. We'd do the sums before touching anything.

What WAservix adds#

The biggest addition is the rest of Tekservix. If a WhatsApp message can't reach someone, SMS Gora can send a text through your own Android phone. And the AI Sales Agent answers customers on those same lines, using content from your website. It's all on a single account, paid from one wallet.

The API stays simple. You get REST endpoints, webhooks and support for text, images, video, audio, documents, stickers, locations and contact cards. Unlimited messages and contacts are part of every plan, not a premium feature. The documentation covers it all, and you can read it before paying a cent.

Then there's cost certainty for growing businesses. Plans step up by number count at a gentle slope, so a growing company isn't punished for adding a line.

Risks that apply to both#

Don't treat a lower price as a lower risk. WAservix and UltraMsg have the same exposure, because the risk comes from how WhatsApp views the number, not from the vendor's logo.

Numbers can get in trouble for:

• Sending to people who never agreed to hear from you.
• Sending lots of identical messages quickly.
• Getting blocked or reported repeatedly.
• Starting bulk sends on a brand-new number.

To reduce those risks, warm the number up with normal conversations, then increase volume little by little. Add delays and personalise your messages. And keep a list of who opted in and when. Our opt-in guide has examples.

Switching takes less time than you'd think#

Your code probably has one function that sends a message. Change the URL, the token and the field names, and you're most of the way there. Update your webhook handler for the new payload format, and check signatures using the X-Webhook-Signature header. For most small integrations, that's a morning's work.

Your number needs some care. A WhatsApp account can have several linked devices, so in principle you can pair the number to WAservix while the old service is still connected. In practice, we'd unlink the old one once you're happy, so two systems aren't answering the same messages.

If you're sending auto-replies from your own code, watch out for loops. Two systems replying to each other's output, or to a customer's automated reply, is an embarrassing way to burn a number's goodwill.

A simple payback calculation#

The UltraMsg column assumes one $39 package per number, so check whether they'd offer you a better rate at higher counts. Even with a discount, the saving should pay for the morning's work several times over.

Three people who'd save money, and one who wouldn't#

A Kuala Lumpur tutor sends class reminders to 90 parents. They've been paying $39 a month for something they use twice a week. WAservix Starter would do the job for $4.50, and they'd also get a screen for sending without any code.

A Warsaw agency manages WhatsApp for twelve clients. On $39 a number that's $468 a month. A WAservix Enterprise plan covers twenty-five numbers for $79, so the agency has room to grow and more than $4,000 a year back in its margin.

A Sao Paulo clinic runs two branches and wants each one to have its own line, with an AI answering after hours. It would take the AI Sales Agent Growth plan at $79, with three WhatsApp numbers and three SMS phones included, and 5,000 AI replies a month.

And then there's the developer whose side project sends a few thousand messages through a working UltraMsg integration and already covers its cost. Saving money is nice, but if nothing is broken and the fee is covered, the time spent moving might be better used on the product itself.

Should you switch?#

Switch if you've got more than one number, if you're paying $39 for light traffic, or if non-developers need to run campaigns. Stay if your integration is stable, your volume justifies the fee and you value not touching it.

If you're new to all this and comparing from scratch, there's no reason to start with the higher price. Run the $1 trial and send real traffic for three days. You might also want to read how we stack up against Maytapi and Whapi.Cloud, the two closest services, and our broader WhatsApp API roundup.
