Description
I’ve spent the last few days prototyping a browser-based game engine stack designed for instant-load, "Roblox-for-Teens" style deployment. The goal is to lower the floor for AA indie devs who want high-fidelity physics and instant web distribution without the overhead of Unity or a heavy Godot export.The Stack Engine: A headless WASM/WebGPU implementation. I’m currently using custom flags and selective streaming to bypass standard browser memory and execution limits.Physics: I’ve ported Jolt (Guerrilla Games) but modified the solver to mimic the original Blam! engine (Bungie/Halo 1-3). It successfully replicates that specific "physics chaos" (unstable vehicle momentum, grenade jumping) that modern rigid-body sims often feel too "clean" to capture.The "Vibe Console": A React-based no-code layer on top of a Godot web-editor clone. It uses an LLM-backed (Claude) interface to allow real-time engine modifications via natural language—essentially mapping prompts to engine dials and knobs.The Vision I want to build a platform where casual/semi-competitive party games launch instantly upon page load. No installs, no long loading bars. I’m launching with three open-source "proofs of concept":A Halo 2-inspired multiplayer arena.A Simpsons Hit & Run style driving sandbox.A 3D "Mousetrap" physics runner.Why I’m posting here I’m a bootstrapped guy with a previous 10x SaaS exit and a light background in PDEs. While I’ve "vibe-coded" the current architecture into existence, I’m looking for a lead systems engineer who lives and breathes low-level optimization.I have the capital and gtm know how, but I need a partner who can help me harden the WebGPU pipeline and ensure the "Vibe Console" doesn't create unmaintainable technical debt.I’d love to hear the community’s thoughts on:The viability of WebGPU for high-fidelity physics at scale in 2026.The "Blam!" physics approach—is there a better way to simulate retro-instability than modifying Jolt's constraints?If you’re a cracked engineer who wants to build the next-gen web gaming substrate, let’s talk.

Could you build this?
No Building a custom WebGPU-based 3D game engine featuring custom high-fidelity physics ('Blam'-style halo engine mechanics) requires specialized knowledge in computer graphics, WGSL shaders, and numerical physics integration.
What it would actually take: The stack would involve Rust or modern TypeScript compiling to WebAssembly, paired with WebGPU and custom WGSL compute shaders. The core difficulties are building a deterministic 3D physics engine capable of handling complex vehicle/character momentum and collision resolution in real-time, plus optimizing asset streaming pipelines for zero-install instant loading in browsers. This demands specialized 3D graphics engineers and physics engine developers.
