Best for a small team wanting a free cloud phone system
Zadarma is a cloud PBX with numbers in 110 countries, free for up to 5 users, with calling apps on every platform. The free plan includes no minutes or numbers, so those are charged as you use them, and prices change with the region you pick.
Who Zadarma is for
- Fits if you run a team of up to 5 and want a PBX without a monthly fee
- Works for businesses that want numbers in many countries on one account
Who Zadarma is not for
- Tight if you need minutes included, because Standard includes none and charges calls and numbers separately
- Watch out: prices depend on the region selector, and the figures here are the page's default World region
- Watch out: annual prices need yearly payment and plans cap users at 5, 10 or 20
- Skip it if you use Linux, since the calling apps page lists no Linux app
Why Zadarma gets a 3.2

Keep Zadarma, or make your own?
Keep it
To replace Zadarma you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 3.2 is higher than 44 of the 44 other business phone systems we grade. It costs $468 a year.
What you could not
- Phone numbers and calls carried over the phone network.
- Phone numbers that change for each visitor so every call is traced to its source.
- An AI model answering your customers from your own help articles.
- Texts from a business number, registered with the carriers.
- Speech turned into text you can trust.
- Apps for macOS, Windows, iOS and Android that stay in step with each other.
- It plugs into other products, HubSpot, Zapier and Shopify among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Zadarma’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
