The open-core 3D creation platform with native WebGPU acceleration, a TSL transpiler and standalone TypeScript compilation under the Apache 2.0 license.
SILOS // LOCK-IN
Expctral was built to end this.
If I leave the platform, my project stays behind.
My shaders are concatenated strings that break and can't be debugged.
Every time the shader language changes, I rewrite everything.
I always start from a blank canvas.
Before creating anything, I have to install plugins and heavy software.
CODE SOVEREIGNTY // OPEN-CORE
Expctral combines WebGPU performance with TSL (Three.js Shading Language) and a transparent open-core model. The runtime and the visual compiler belong to the community under Apache 2.0.
Expctral replaces data lock-in with total developer autonomy.
Expctral fundamental principleThe output is clean, independent TypeScript: a real and permanent asset.
No downloads. If there is a modern browser, there is Expctral.
WebGPU gives direct access to modern graphics cards, with parallel compute shaders.
ECOSYSTEM // 4 SURFACES
Integrated gears designed to shorten the distance between creative intent and scalable monetization.
ENGINE // WEBGPU/TSL RUNTIME
Dual pipelines in parallel: a Compute Pass on storage buffers and a Render Pass targeting 60+ FPS, with a visual TSL compiler that only emits valid shaders.
This page's hero runs on that same runtime, live.
STUDIO // VISUAL GRAPH EDITOR
A reactive editor in React Flow + Zustand with real-time multiplayer collaboration through Yjs CRDTs.
REGISTRY // ASSET & SHADER HUB
Portable .exp packages, Code Refraction with automatic credit and a revenue split built for creators.
HUB // DEV PORTAL
Documentation, AIO/GEO structured data and community support. The site proves the product: you are looking at its first version.
STUDIO // PRISM
Connect nodes, tune speed, density and color, then eject the TSL code. Every node lives in four frequencies: switch the tabs to see and hear them.
Reactive state read by the Math Wave on every change.
Sinapse Engine rules: storage buffers aligned to 16 bytes and workgroups in multiples of 64.
TSL // SOURCEMAP · PARTICLE FIELD
The preview runs on three/webgpu in your browser, using exactly the TSL you eject. The node editor itself is a prototype of Prism Studio.

REGISTRY // ORBIT CLUSTER
Monolithic .exp packages carry the node graph and its parameters. Every refraction keeps an immutable lineage back to the primordial author. This catalog is a working simulation with the four Primordial Spectra.
No package matches this search.
Immutable history: every copy keeps credit to the primordial author.

ARCHITECTURE // SINAPSE + PRISM
Four decisions that turn a visual graph into fast, portable code.
01 // DUAL PIPELINES
The Compute Pass runs physics, particles and instancing on storage buffers inside the GPU. The Render Pass receives that data already in memory and draws geometry, light and TSL materials.
02 // VISUAL TSL COMPILER
Instead of concatenating fragile GLSL or WGSL strings, every node maps to a real TSL function. Shaders created visually are syntactically valid and transpile to both WebGPU and WebGL.
// Spectrum Color node → TSL material.colorNode = mix( uSpectrumA, uSpectrumB, clamp(uMix.add(hash(instanceIndex)), 0, 1) );
03 // 0% LOCK-IN
The graph is transpiled into a standalone .ts file with pure TSL functions. It only needs standard Three.js and runs on any server or React/Next.js app.
import * as THREE from 'three/webgpu'; import { Fn, uniform, instancedArray } from 'three/tsl'; // zero proprietary dependencies export function createVortex(renderer) { … }
04 // MULTIPLAYER CRDT
Yjs CRDTs over WebSockets let several creators move nodes, change parameters and connect wires in the same graph at the same time, with live telemetry cursors.

Founder and creator · Mezzetti⁴⁰⁹⁶ Studio
Each day is split between deep engineering (Sinapse Compiler, WebGPU, Prism Studio) and community, investors and Build in Public updates.
Unrestricted commercial use, explicit patent grant and preserved attribution.
Planned fiscal host (501(c)(6)) to receive community and B2B support with financial transparency.
Development in sequential phases with acceptance gates: zero type errors and all tests green before anything ships.
SUPPORT TIERS // OPEN-CORE
Monthly support pays for servers, international domains, certificates and the Sinapse Compiler infrastructure. In return you get access and recognition, and the code stays open for everyone under Apache 2.0.
V1.0 MVP goal
R$ 15,000 · US$ 3,000
Servers, domains, certificates and the first Sinapse Compiler infrastructure.
V1.5 consolidation goal
R$ 50,000 · US$ 10,000
Consolidating Prism Studio, senior engineering support and preparing the angel round.

ROADMAP // PHASES 0–4
Sequential phases with exit gates. A phase only closes when the type check has zero errors and the test suite is fully green.
PHASE 0 // W 1–4
AST security, storage buffer alignment, OSC and Apache 2.0 framework.
PHASE 1 // W 5–10
TSL engine, dual WebGPU pipelines and the TypeScript ejector.
PHASE 2 // W 11–16
React Flow canvas, Yjs CRDTs, offline-first PWA and the local assistant Dra. Ada.
PHASE 3 // W 17–22
.exp packages, Code Refraction and the 85/15 revenue split.
PHASE 4 // W 23–28
International restructuring and global commercial expansion.

Click [ ⚡︎ EJECT TYPESCRIPT ]. Your node graph becomes a clean .ts file with pure TSL functions that only needs standard Three.js. It runs on any server or React/Next.js app, with no Expctral dependencies.
Yes. Apache 2.0 allows unrestricted commercial use without opening your product's code, grants an explicit patent license from every contributor and only asks you to keep the copyright notices in modified original files.
Expctral falls back to WebGL2 automatically. TSL transpiles to both WebGPU and WebGL, so the code you write today is future-proof. The live counter at the top of this page shows which renderer your browser is using right now.
The first goal (R$ 15,000) covers servers, domains, certificates and the initial Sinapse Compiler infrastructure. The second (R$ 50,000) consolidates Prism Studio, brings in senior engineering support and prepares the angel round.
The plan is fiscal hosting through the Open Source Collective, a US 501(c)(6) nonprofit, with GitHub Sponsors integration for community and B2B sponsorship and public financial transparency. Enrollment is still in progress.
In the Spectral Registry, creators publish TSL materials, presets and 3D projects. 85% of each sale goes to the creator and 15% stays with the platform for infrastructure and engine development.
Development follows phases 0 to 4 (see the roadmap above). Today you can try the Prism Studio prototype on this page and eject its TypeScript.
