ibisjp/ibis-office (ibisOffice) is an office suite built with Rust and GPUI. It aims to open, view, edit and save Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) documents. The latest release published in the repository is v0.8.4. However, the provided information lists no changes for this version, so the specific release changes cannot be confirmed.
The project handles documents in both desktop apps and web browsers, and uses the GPU to draw the screen. According to the README, the same codebase targets Windows, macOS and Linux as well as the web (Wasm), and supports DirectX, Metal, Vulkan and WebGPU as rendering backends. The goal is for Word, Excel and PowerPoint documents to look the same in ibisOffice as well. The README explains that compatibility is checked by comparing pixel by pixel with PDFs produced by actual Office. The license is AGPL-3.0.
The performance table and the figure of 70,000 tests are presented as an SVG image and a README description, and the provided information does not confirm any means to reproduce them. The repository mentions benchmark data under test/ and crate-level tests, but this alone makes it hard to judge per-GPU-backend speed or rendering compatibility. Therefore, what can be confirmed now is the design and the goals, and measured performance requires separate evidence.
