Kdb+/q
Kdb+/q can be downloaded from https://kx.com/developers/download-licenses/
In particular, there are two free versions of kdb+/q: the 32 Bit Personal Edition and the 64 Bit Personal Edition (On-Demand).
Both editions are licensed for personal use.
The 32 Bit Personal Edition:
- is permitted to run on-premises;
- is permitted to run on cloud;
- provides access to KX Fusion interfaces and integrations;
- provides access to community support;
- Linux/Mac/Windows/Raspberry pi versions are available.
The main limitation of the 32 Bit Personal Edition and, more generally, of any 32-bit program, is that it can only ever use up to 4 GB of memory. That's due to the 32-bit address space, since 2^32 = 4,294,967,296 bytes. For some use cases this may be a serious limitation.
The 64 Bit Personal Edition (On-Demand):
- requires "always on" internet connection;
- is permitted to run on-premises;
- is compatible with KX Developer and KX Dashboards Direct;
- provides access to KX Fusion interfaces and integrations;
- provides access to community support;
- gives regular access to upgrades;
- Linux/Mac/Windows versions are available.
The 32 Bit Personal Edition can be downloaded immediately, whereas for the 64 Bit Personal Edition (On-Demand) you would need to request a license. Both editions are available via https://kx.com/developers/download-licenses/

Q Insight Pad
Q Insight Pad (sometimes referred to simply as qPad) is a kdb+ client, written in C++ to run under Windows; as a result, it is fast, memory-efficient and easy to use. The author Oleg G. Zakharov makes a special emphasis on providing a Windows-style GUI that is visual, simple and intuitive.
Q Insight Pad provides simple but useful visualization capabilities.
