WASM-Native Performance Monitoring for Web Apps

C5/10March 11, 2026
WhatAn observability tool purpose-built for WebAssembly web applications that profiles the JS-WASM boundary, identifies glue-code bottlenecks, and shows exactly where marshalling overhead is killing performance.
SignalMultiple developers highlight that the JS-to-WASM glue layer is a massive hidden performance footgun — people build WASM apps expecting speed gains and get surprised by marshalling costs, with no good tooling to diagnose where time is actually spent.
Why NowAs WASM adoption grows and the component model changes the interop story, developers need to understand whether their specific workload (DOM-heavy vs WebGPU vs compute) actually benefits from WASM, and current browser DevTools don't surface this.
MarketTeams shipping WASM-based web apps (gaming, CAD, video editing, AI inference in browser); niche but high-value segment willing to pay for perf tools. Competitors: none purpose-built for WASM profiling. ~$50M addressable.
MoatDeep technical expertise in WASM runtime internals creates a knowledge moat; integration with browser engines and build tools creates switching costs.
