Tags: wasm, rust, spreadsheet, engine, performance

Score: 7.8/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 7)

Titan is a high-performance spreadsheet engine written in Rust and compiled to WebAssembly, designed for browser-based recalculation of large sheets. It uses a chunked struct-of-arrays memory layout, bytecode VM with lazy range evaluation, and zero-copy viewports to minimize WASM boundary overhead. The project is notable for its careful engineering trade-offs and potential to power faster web-based spreadsheet applications.

Target audience: frontend developers, web application developers, spreadsheet tool builders
