IFCescu

A web application for viewing, editing and checking IFC models directly in the browser, with no installation. IFCescu is developed in-house by Dan Vlăsceanu, within the buildingSMART Romania team, based on the open-source IFC-Lite library developed by Louis Trumpler (LT+). For full functionality, we recommend opening it in a new tab or using the enlarged viewer (buttons below).

🎁 Made available for free, as a tool for the entire AEC industry in Romania.

🔒 Privacy guaranteed — your IFC files are not uploaded to any server. IFCescu is built on the open-source IFC-Lite library, a fully client-side viewer: models are processed directly in the browser (WebAssembly) and never leave your browser. You can confidently load any model. Per the IFC-Lite documentation: "No backend, no upload — the model never leaves the browser tab."
