Kx Developer ( KX Developer ) is an exceptional, lightweight, browser-based q IDE. Features like its Grid Table View and integrated charting are things I have come to rely on heavily over the years for ad-hoc data analysis, and I am certainly not alone.
Unfortunately, after upgrading to the new KDB-X 5.0 Community Edition engine, Kx Developer fails to boot entirely with the error: [developer] failed to start Kx Developer: kdb+ version 5 is not supported - supported versions are 4.1 4.0 3.6 3.5 3.4.
As a result, I have been forced to revert to the old Java-based KDB Studio. While it works via standard IPC, the user experience is a massive step backward compared to the modern, streamlined feel of Kx Developer. Ironically, I was demoing Kx Developer to a fellow developer just yesterday, and they were incredibly impressed by how clean it was—so it was very disappointing to see it not working at all today.
I understand the push toward the new VS Code extension ecosystem, but many developers on native Linux environments intentionally avoid installing massive, corporate-telemetry-heavy platforms like VS Code just to run a lightweight scratchpad.
Please consider updating the internal compatibility flags for Kx Developer to support v5.0 namespaces, or open-source the tool so the community can patch it to work with KDB-X.
