I found Adjust's tracking was difficult to process.

Comprehensive tracking and measurement capabilities, including in-app event tracking, in-app purchase tracking, and attribution trackingSupport for a wide range of platforms and ad networksIntegration with other marketing tools such as Facebook Ads and Google AdWordsUser-friendly and intuitive interface

Head of growth

Mobile measurement partner very complete and easy to use for an experienced marketer.

Founder and CEO

Setting it up is extremely difficult, and their set-up documentation is both poorly written, inaccurate and often outdated.

Martech Analyst

The purpose of Adjust is to assist with mobile attribution, and it does this very well; however, the user interface and campaign setting are not designed for applications that serve multiple business units. and the lack of a local payment method, generates many unnecessary tax costs.

Performance Marketing Analyst

It is necessary to integrate Adjust and your database, which is more laborious and can end up making analysis more complex and time-consuming.

Software Engineer

Some features (e.g. full-text search) require third-party services

IT SUPPORT SPECIALIST

Google Firebase is a great tool for building and managing web and mobile applications.

It is there in the same platform and architecture, but it takes 3-4 clicks to get to where you want to be.

From the authentication system, which is super complete and secure, to the nosql database, Firebase is a complete product that has served me for years without ever letting me down.

The real-time database and authentication features are particularly useful.

It is also pay as you go so it is easy to setup for free, use it freely for quite some time until you reach the point where it s time to pay when you are properly settled.

Firebase isn't that complete and I personally would go using other enterprise services for production apps.

Firebase makes backend development fast and efficient.

Full Stack developer

The cost, beign in Africa and still a students, implementing large apps will be costful for me, but they have implemented a pay as you go plan, and some features are free up to a certain point

For beginner and small project where small amount of data is processed, this could be the best to go for. But for large scale data processing, more integration of other software is needed.

Subject Matter Expert

Also, Firebase offers various analytics tools that help me to gain insights into users behavior and app performance.

Senior Developer

In particular, its real-time database, cloud features, and hosting capabilities are amazing and simplify development.

The security rules are limiting and feel ambiguous to set up

Head of Marketing & Growth

I like how you can integrate both OS systems for mobile apps and see data in one report/dashboard.

MoneyLion

It gives me all the app usage and traffic data which is insightful while making further marketing decisions.

Seo Executive

All in all, over the last 12 month I have managed to automated a significant amount of processes that would have otherwise required manual intervention, thus saving time and money.

From the ease of integration with my apps to the array of powerful features available, Firebase has exceeded my expectations in every way.

Office Assistant

While Google Firebase offers many benefits, I found its pricing structure, especially for high-traffic apps, to be complex and potentially costly.

Expensive for medium-to-large-scale projects

The authentication system is a gem that gives you several ways to register your customers (even anonymously) on all the main platforms on the market such as google, apple, facebook, etc.

Student

We can ceaselessly screen the mental soundness and standard progression of our occasions in the occasions segment and furthermore see the exhibition of different application renditions and crash rates on various cell phones.

I appreciate that it provides various forms of affirmation (browse of email, phone number, casual networks). That you can definitely produce a record without the need for a credit or charge card is something I prefer.

Connectivity manual for developers

Using the JSON key provided to sync and authenticate our app with Firebase, we used Firebase to easily authenticate our users, and we used Firebase to integrate social media signup methods on our app.

web developer

However, I notice limitations in terms of customization, scalability, engagement tracking, reporting/analytics, customer segmentation, and A/B testing capabilities. but I can say  these limitations are not unique to Firebase

Accountant

Firebase enables developers to keep tabs on important statistics like in-app sales, subscriptions, and sign-ups.

web devloper

Firebase's real-time database is optimized for real-time synchronization and offers limited querying capabilities, which can make it challenging to perform complex queries or search operations. While firebase offers cloud functions to run server-side logic, it is limited compared to a traditional backed service that offers moe control over server configuration and management.

Features such as security have little documentation and it is difficult for users to secure their database with specific rules. As Firebase is constantly upgrading, there needs to be a more in-depth documentation of their most current changes and advanced features.

Firebase doesn't discriminate whether you are an iOS, Android, or web developer; the Firebase tool can be integrated,We used Firebase primarily for our mobile app, which was built using Android Studios.

Firebase has been a part of our routine for more than 2 years now and It is the best go to product for the prototyping and quick development as it provides complete suit from Hosting to Database

Firebase is paid service so as your app grows or needs more resources, the cost can become very high.

It has great features which allow users to create, develop, and execute applications and provide authentication to our application.

Building and managing a range of applications, whether they are for the web or mobile, is incredibly easy with Firebase.

Limited query and search functions

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.

69% of reviewers feel negative about Firebase’s querying capabilities. Users report frustration with the lack of advanced query options, such as logical OR operations and efficient text search. They say complex queries are difficult or slow, and batch processing large datasets is cumbersome. Reviewers mention that the non-SQL structure limits flexibility, making it challenging to perform aggregations or implement features found in traditional databases. Many find that search and indexing are not as robust as needed for more sophisticated applications.

Frequent bugs and instability

Founder

Sometimes, the instructions are unclear and I get errors that I cannot figure out since I never suspect the error was sourced by the instructions.

44% of reviewers feel negative about Firebase’s stability due to bugs and issues. Users mention encountering errors in authentication, real-time database, and Firestore, sometimes after new releases. They say documentation can be unclear when changes roll out, making troubleshooting difficult. Reviewers note that bugs can delay project progress and that some issues are considered expected behavior by the platform. Many express frustration with delays in bug resolution and the persistence of errors in certain features.

Challenging data handling for complex needs

35% of reviewers feel negative about Firebase’s data management. Users report difficulties managing large, highly structured, or complex datasets due to the JSON-based, non-SQL structure. They say it’s hard to perform advanced filtering, segment data, or handle big data efficiently. Reviewers mention issues with importing/exporting data, limitations on data nesting, and problems retrieving or editing information. Many find the platform less suitable for applications requiring robust data manipulation or handling significant data volumes.

Unpredictable and high costs

Software Developer

The only cons in my opinion are the potential costs as your software grows and the lock-in. If you haven't analyzed the cost for firebase then you may be surprised in the future by how much you are paying.

38% of reviewers feel negative about Firebase’s pricing. Users say the cost structure is confusing, with separate charges for different features and unclear documentation. They report that the free tier is limited, and costs can escalate quickly as user numbers or data usage grow. Reviewers mention difficulty in estimating future expenses and express concern about affordability for small or scaling projects. Many highlight that certain features require paid plans, and unexpected charges can impact budgeting.
