Compare UCaaS Platforms

UCaaS platforms bring business calling, video meetings and team messaging into one service; the right choice depends on the communication features your team needs and how it fits with your current apps.

Compare the board’s signal score out of 10, then check the feature columns for calling, meetings, messaging and other needs. API, open-source and free-tier marks show whether a platform has a public API, open-source code or a free plan.

How to choose

Which calling features does my team need?

Start with the calling features your work depends on, such as PSTN calling, SMS/MMS, auto attendant or call recording.

The board compares these features alongside video meetings and team messaging, so you can focus on the functions your team uses.

How many people need to join a meeting?

Check the meeting participant limit against the size of the meetings you expect to hold.

Video meetings and participant limits are separate comparison points, so confirm both before choosing.

Which devices and platforms should it support?

Match platform support to the devices your team already uses. The board lists Android, iOS, web, macOS, Windows and Linux support.

Check the relevant platform entry for a service before relying on it on a particular device.

How should I compare plans and prices?

Look at the free-plan mark and the paid-from price, where one is listed. A free trial is different from an ongoing free plan.

For example, the listed pricing notes identify free plans for Dialpad Meetings and Alcatel-Lucent Enterprise Rainbow, while Net2Phone Office shows a starting price of $19.99 per user per month on annual billing.

What should I check about app connections?

If a platform needs to connect to tools your team already uses, check whether it has a public API and confirm that it supports the specific connections you need.

An API is a published way for software to exchange information. The API mark does not by itself confirm a particular app integration.

Questions

What does a UCaaS platform do?

It brings business communications such as calling, video meetings and team messaging into a software service.

What does the signal score mean?

It is a score out of 10 based on published signals: usage, public API, documentation depth, open-source code and a free tier.

How do I tell if a platform has a free plan?

Check the free-tier mark and the plan details. A free trial is not the same as a free plan.

Which features should I compare in UCaaS software?

Compare video meetings, PSTN calling, team messaging, SMS/MMS, auto attendant, call recording and meeting participant limit.

How can I check whether UCaaS software works on my devices?

Check its platform support for Android, iOS, web, macOS, Windows or Linux against the devices your team uses.
