Curated — checked & pruned 2026-06-13

Recovered from the original Aubit4GL links page, then link-checked and pruned — dead, parked, and repurposed domains were removed. What remains below is live and still relevant to the x4GL / Informix-4GL world. Found something that belongs here? Let us know.

• 4Js — Genero — the modern commercial Informix-4GL successor; the Genero low-code / 4GL development suite.
• Querix — 4GL development suite and application-migration tooling.
