Try it now!

Trying Firebird is a very simple task. The installer size usually is less than 10MB (depending on the operating system of your choice) and fully automated. You can download it from the Firebird main site.

You will notice that Firebird server comes in three flavors: SuperServer, Classic and SuperClassic. Starting with Firebird 3, all the architectures benefit from SMP machines. SuperServer shares its cache among the database connections and uses threads to handle each connection. Classic starts one independent server process for each connection made. SuperClassic offers multithreaded single process server with independent cache for each connection.

The embedded version is an amazing variation of the server. It is a fully featured Firebird server packed in just a few files. It is very easy to deploy, since there is no need to install the server. It is ideal for demonstrations s or standalone desktop applications.

Firebird comes with a full set of command line utilities that allow you to create databases, retrieve database statistics, run SQL commands and scripts, perform backups and restores, etc. If you prefer to use a GUI (Graphical User Interface) tool, there are lots of options to choose from, including free ones. Check the list at the end of this paper for a good start.

On Windows, you can run Firebird as a service or in application mode. The installer can create an icon in the Control Panel that you can use to manage the server (start, stop, etc).


There are a lot of papers, FAQs and articles that you may want to check in the Firebird main site. Also, you can check if your country has a localized community site or discussion list, so you can get support in your native language.

All this information can be found digging around in the Firebird main site. Also, check to get up to date with the most recent news related to Firebird.

For all sized databases

Some people thinks that Firebird is a RDBMS to be used with just small databases and a few connections. They are wrong! Firebird is being used with many big databases and lots of connections. You can read full article about 1.7 Terabytes database.

Would you like to help?

Due to the nature of an Open Source project, anyone can contribute by developing new features or fixing bugs. If you want to become a member of the Firebird Development Team, download the Firebird source code from sourceforge and study it. Also, you may join the fbdevel discussion list to get in touch with other developers (note: fbdevel is not a general support list, so don’t ask support questions there, instead use firebird-support for free community support).

You don’t need to be a coder to help the project. Become a member of the Firebird Foundation or make a donation and you will be helping to fund core developers so they can invest more time working in the project.

Thanks for these two minutes...
