Executive SummaryUpdated on Jul 27, 2025

PostgreSQL and Firebird SQL are two open-source databases competing in the market. Based on comparison across different sections, PostgreSQL seems to have an edge due to its extensive feature set and strong cloud deployment capabilities.

Features: PostgreSQL provides a rich feature set including comprehensive SQL standards support, complex query handling, and superior data reliability. It supports JSON and NoSQL features, making it versatile for diverse applications. Additionally, PostgreSQL's extensibility is valued by developers. Firebird SQL, contrastingly, offers simplicity and ease of use, an ideal choice for environments with limited resources. The lightweight nature of Firebird makes it straightforward to administer and deploy.

Room for Improvement: PostgreSQL users call for improved replication, enhanced user-friendly properties for beginners, and better performance on large-scale queries. Firebird SQL could benefit from enhancements in handling larger databases, more graphical management tools, and boosted integration capabilities with existing development frameworks.

Ease of Deployment and Customer Service: PostgreSQL's versatile deployment options across cloud configurations enhance its applicability in complex settings. Despite strong community support, there is a demand for centralized documentation. Firebird SQL is praised for easy on-premises deployment and has solid community-driven support, though it lacks a centralized commercial-grade support system.

Pricing and ROI: Both databases are open-source with no licensing costs, providing significant savings over commercial options. PostgreSQL might incur additional costs for support services but offers substantial ROI, valuable for startups and transitioning enterprises. Firebird SQL stands out as cost-effective in scenarios where stability and simplicity are prioritized over advanced features.

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.

Offers simplicity and is cheaply priced

I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

Quotes from Members

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

Pros

"I can deploy it on Linux, Mac OS, and Windows — it's very easy."

"I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB."

"The solution is very useful for stock management."

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

"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."

"The product was easy to use."

"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."

"I find the ease of deployment to be the most valuable aspect of this solution."

More Firebird SQL pros

"The most valuable feature is the performance."

"The solution has many valuable features such as it easy to use and the interface is intuitive."

"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."

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

"The product is quite flexible."

"Scalable, stable, and easy to manage database system, with a straightforward installation."

"The product is easy to use and works fast for relational databases."

"The solution is scalable, it is very good."

Cons

"In the next release, it should support JSON, XML, and replication with third-party tools."

"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."

"On large databases, we have some difficulties."

"The main feature I expect is to be able to work with different databases at the same time because that's a wishlist item for me."

"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."

"The security of the users could improve in Firebird SQL."

"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."

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

More Firebird SQL cons

"PostgreSQL could improve by adding data warehousing tools."

"I had some issues when I integrated with the Jupyter Notebook."

"The interface could be much better."

"The search option is not very good."

"I'd like to see better memory management. I think that that's one of the few areas that Postgres does not handle as well as MySQL does or did."

"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."

"I have noticed that user and access management should be improved."

"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."

Pricing and Cost Advice

"It's open-source and free."

"It is okay."

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

"Firebird SQL is an open-source solution, which means it is a free product."

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

"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."

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

More Firebird SQL pricing and cost advice

"The community version of Postgre is basically free."

"PostgreSQL is a free and open-source database."

"The solution requires a license."

"The licensing model is good."

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

"We are using the free version of PostgreSQL."

"There is an annual license."

"It is open source. There is no licensing."
