Executive SummaryUpdated on Apr 20, 2025

PostgreSQL and Firebird SQL are both open-source database solutions in the same category, but PostgreSQL seems to have the upper hand due to its scalability, performance, and extensive feature set according to user reviews.

Features: PostgreSQL includes complex query handling, extensive language support, and robust integration capabilities. Firebird SQL offers ease of deployment, strong transactional integrity, and minimal administration requirements, making it suitable for lightweight applications.

Room for Improvement: PostgreSQL could improve query speed, support for additional SQL standards, and further enhance scalability and replication. Firebird SQL could benefit from better handling of larger datasets, improved support for modern data trends, and increased popularity among larger user bases.

Ease Of Deployment and Customer Service: PostgreSQL supports versatile deployment options including on-premises and cloud environments with community-driven support. Firebird SQL is mainly used in on-premises setups, known for its ease of deployment with minimal maintenance.

Pricing and ROI: Both PostgreSQL and Firebird SQL are open-source, offering minimal costs and rapid ROI. Additional costs with PostgreSQL may arise from third-party products or services, while Firebird SQL remains completely free, appealing to cost-conscious businesses.

A reliable tool that offers good performance and is easy to use

I have had no issues with the stability of the product since it has always been a 100 percent reliable product and much better than the other databases available in the market. The multi-platform part is not good, especially when locked into things like Windows. You can judge your platform with Linux or Unix or whatever since they are good.

Transaction processes are fast and good replication capability

Use cases include querying data warehouses and databases to fetch data for clients already working on PostgreSQL. We also use Postgres for building reports It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping. The query speed is fast, and the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Robustness is the absolutely main feature."

"We are happy with the event capabilities of Firebird SQL database. We can raise events from it and display them in our application."

"The most valuable feature of Firebird SQL is the creation of databases."

"Firebird SQL is an open-source solution and can run on most operating systems, such as Linux, Unix, and Windows."

"The documentation is very well written."

"I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server."

"It helps us in detecting all kinds of problems in the code, such as bad quality, unclear code, or any violation in the code or best practices."

"The product was easy to use."

More Firebird SQL pros

"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."

"PostgreSQL is very powerful, easy to manage, and has many features."

"The tool is user-friendly."

"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."

"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."

"It is easy to use."

"The performance is good."

"It's a standard reliable database management system."

Cons

"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."

"On large databases, we have some difficulties."

"It is not easy to integrate the tool with Visual Studio."

"It would be interesting if they added functionality with redundancy, reputation, and variability."

"It would be good to have more automation and integration with the tools from other vendors."

"I don't think the solution is very scalable, because the scalability of the performance when using more than one process is not very good."

"We would like to improve the management of very large databases."

"Database sharing is a capability that Firebird SQL lacks."

More Firebird SQL cons

"The solution needs to improve the query, documentation, and JSON data functionality."

"The pricing could be better."

"They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great."

"PostgreSQL could improve by being more user-friendly. In SQL Server they have a studio where you can easily do management but not in this solution."

"It needs more integration."

"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."

"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."

"I'm not really able to customize it."

Pricing and Cost Advice

"There is a yearly maintenance fee for the use of the solution."

"I was using the free version of Firebird SQL."

"The most valuable feature of the solution is that it is freely available."

"There is no licensing cost for this solution, as it is open-source."

"It is a public domain system as every customer can install it on their system without paying any license fee."

"We are using the free solution, so there is no cost involved."

"It is okay."

"The tool is open source."

More Firebird SQL pricing and cost advice

"It is also open-source so it is free."

"The community version of Postgre is basically free."

"This solution can offer a cheaper choice for customers since it is open-source."

"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."

"We use the open-source version of PostgreSQL and not the enterprise edition."

"It is free. There is no license on it."

"There is an annual license."

"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
