Excel-speed in the Browser.
The high-performance spreadsheet engine for modern web apps. Built on Rust and WebAssembly for zero-copy memory access and sub-millisecond calculation cycles.
Real-time Recalculation
Because Titan is compiled to WebAssembly, it brings native execution speed to the browser. It resolves massive dependency chains in milliseconds, so the grid never locks up while users are typing.
60FPS Execution
Batched recalculations finish in under 10 milliseconds, easily beating the 16ms budget required for a smooth user interface.
Zero GC Pauses
Titan manages memory internally in WebAssembly. This bypasses the JavaScript garbage collector entirely, preventing unpredictable browser freezes.
Engine Capabilities
Architected in Rust to bypass JavaScript runtime limitations and deliver deterministic, ultra-low latency execution.
WASM-Compiled Core
Predictable, native-level execution via a custom Rust stack-based VM and Pratt parser.
Zero-Copy Memory
Bypasses JS garbage collection by sharing memory buffers directly between the engine and UI.
Topological Graph
Resolves complex chained formulas flawlessly using Kahn's algorithm with cycle detection.
Atomic Time-Travel
Instantly undo or redo massive batched structural mutations with O(1) state snapshots.
Array Math (Matrix Broadcasting)
100,000 evalsParsing & Compilation
30,000 formulasProven WebAssembly Performance
We benchmarked Titan against HyperFormula (the industry standard JS formula engine) across 10 extreme scenarios. Titan processes data in WASM linear memory, bypassing the JavaScript garbage collector to provide predictable, deterministic speeds even under massive loads.
- check_circle Memory Allocation: 5.7x faster (100k raw cell inserts in 70ms)
- check_circle Data Processing: 2.8x faster VLOOKUPs and SUMIFs
- check_circle Absolute Stability: Handled massive structural mutations (inserting rows across 20k chained formulas) in just 14ms, a test where Javascript completely crashed.
