Could you build this?
No Compiling, simulating, and synthesizing VHDL/SystemVerilog in the browser requires porting complex open-source EDA tools (GHDL, Icarus Verilog, Yosys) to WebAssembly or running isolated sandboxed container runtimes with interactive waveform renderers.
What it would actually take: A production implementation requires compiling complex C/C++ EDA toolchains (Yosys, GHDL, Icarus) to WebAssembly with Emscripten or running low-latency Linux microVMs/containers (e.g. Firecracker). The frontend needs custom hardware netlist visualization (ELK/Graphviz) and dynamic VCD waveform parsing into canvas-based viewers. This requires specialized knowledge in hardware description languages, compiler tooling, and WebAssembly compilation of large native C++ codebases.

Competitors mentioned: Visual Studio, Vivado, Quartus, Xcode, Android Studio
Concerns raised: 12-month access limitation instead of unlimited lifetime access, EDA tools have poor user experience and steep setup barriers for beginners
