It provide very good insight about the user interaction and its behavior. Also  AI delivery is my favorite as it improve the click rates of our notification.

Push notifications that work really great on web and mobile devices, clean interface with a bunch of features  that easy the way we develop and they have a great support.

Even if you're not, there are probably videos you can find that'll guide you through doing whatever you might want to achieve with it. Thank this to the awesome community build around it.

Musician/Developer

The slightest change (http to https) meant that I lost all my subscribers that I had worked hard to build over a few years. It was the biggest letdown before they added the paid service.

software developer

Great tool for marketing departments and to generate important amounts of traffic. Simple and effective GUI.

Web Developer

Their pricing plans are very accessible, and their free plan is great, it allows you unlimited subscribers up to 10,000 recipients per message.

What I liked most about OneSignal is its versatility and ease of use.

It is easy to use and the support is super if you need help.

Timely notifications to readers/listeners. Connecting with them almost instantaneously was a good feeling.

It was really simple to integrate with my website and I was able to get started for free which was great. I needed some assistance with a configuration issue and can vouch for their technical support.

IT Admin

Overall expierience is great. I'm happy with the platform.

It is basically API based, so we start with a trial version, and I think it is perfect to create our new site or app marking with the help OneSignal.

We were looking for a solution to implement push notifications for desktop, mobile and other platforms. And OneSignal did great job there.

Student and Learner

The ease of integration with push notifications is quite easy to implement.

Dashboard can be a bit a bit confusing at the beginning.

Doesnt have advanced features. Unless you are a beginner, using One signal might be boring for you.

I can't find something I really don't like about OneSignal, it is the # 1 Push Notification Platform.

Firebase

software engineer

The documentation is fantastic and I especially love their unofficial Discord community -- great way to get instant feedback to questions and more.

Frontend Developer

Super easy to deploy to the server (much better than AWS in this). Great, easy to use UI and advanced features.

I love how easy to use Google Firebase is. My business managed to setup our application to production within a month thanks for the super detailed documentation.

Software Engineer

Overall really loved working with Firebase Cloud Messaging, it worked great with our React Native mobile app and supported all the features we needed.

Social Media Marketing

It is a strong platform to build applications and very easy to use. It keeps the team connected and the adversity of the platform really makes it a finest choice for our developers team.

Chief Technology Officer

The execution is deplorable. They make it so confusing and awkward to setup, so much back and forth.

Firebase has been stable and fast, the end-user experience with Firebase Authentication is also good. Getting started is relatively easy for typical usage, by following the tutorials.

Senior Android Developer

Crashlytics is great and very modern. Filtering crash reports and instances of thwm is really good and clean.

Great integration and support with Kotlin and Intellji making it one of the best platforms for android app developers.

Big Data Developer II

Firebase is super fast, real time data transfers are perfectly designed and it's a complete platform. It has all kinds of tools to analyse data in real time.

The main disadvantage is the search facility , which needs to be addressed. As the entire database is a json file its is difficult to search particular object.

Founder

Firebase has extremely good documentation for almost every language out there. It is very easy to figure out, set it up, and use.

UX Designer

Also has a lot of problems with JS integration, there are some things that just doesn't work and you don't have an idea why. In terms of usability, messages at terminal are not very comprehensible.

iOS / Android developer

The whole firebase suite and the free price tier which is great for POC and startups.

Information Systems Manager

My favourite feature about Firebase is how it makes it easy to integrate authentication into an applications and makes it simple to manage users without building a backend.

Software Developer

Perfect platform for startups or low budget developments.

The main thing is the community. Firebase has a huge active community and that is one of the main reasons why beginners can try this without any hassle.
