Full-Stack AI Engineering.
Zero Paywalls. Built to Finish.
Other AI builders cut off your code when hitting token limits or lock backend databases and custom domains behind $20/month plans. LucasMarc Studio orchestrates 5 specialized agents with automatic rate-limit checkpointing to build, sandbox, and deploy complete applications.
Deploy to lucasmarc.dev/sites/[customname] in one click or map your own custom domain for free.
Build a real-time 3D product configurator with /web3d_engine and /fullstack_dev, connect checkout to @stripe, and isolate my API key in the backend vault.
// Secret keys stay 100% on the backend — never exposed in browser
module.exports = async function(req, context) {
const { action, payload } = req.body;
const stripeKey = context.secrets.STRIPE_API_KEY;
if (action === "createCheckout") {
return await context.fetchJson("https://api.stripe.com/v1/checkout/sessions", {
method: "POST",
headers: { Authorization: `Bearer ${stripeKey}` }
});
}
return { status: "verified", sandbox: "isolated" };
};
5 Model Effort Tiers. Generous Daily Energy.
Every account receives 100% Daily Energy that automatically resets every midnight. Pick lightweight tiers for rapid prototypes or unleash the full 5-agent studio for complex full-stack platforms.
Rapid Prototype
Powered by high-speed Llama 3.1 8B Instant. Builds up to 20 micro-tools, calculators, or landing pages per day.
Standard Builder
Routes to Llama 3.3 70B Versatile with 1x QA verification pass. Great for multi-view dashboards and interactive web apps.
Hybrid Multi-Agent
Splits planning and coding across Groq 70B Architect and G4F Frontend/Backend specialists with automatic token stitching.
Deep Full-Stack
Dedicated UI/UX Shader Agent, isolated VM backend sandbox generation, and 2x self-healing DOM validation passes.
Autonomous 5+ Min
Unlocks all 5 agents, multi-pass token-cutoff stitching, and 60-second rate-limit checkpointing for massive full-stack builds.
Modular AI Skills Studio
Extend the AI's engineering capabilities in dashboard.lucasmarc.dev/skills. Create private proprietary workflows or publish public skills for the community. Enable any skill and invoke it directly in chat with /{skillname}.
Complete React/HTML5 frontend + Node sandbox wiring.
Three.js, WebGL shaders, interactive 3D scenes & physics.
Bento grids, micro-animations, and high-contrast themes.
60FPS HTML5 Canvas games with audio & collision loops.
20+ App Connectors & Custom APIs
Link external platforms or register your own custom API endpoints with custom headers. Reference any integration in chat using @{connectorname} and your keys are automatically injected into the protected backend vault.
Instant Subpath Hosting
Deploy any project immediately to lucasmarc.dev/sites/customname. Real-time database verification checks if your chosen slug is available and publishes your live build in milliseconds.
Protected Backend API Vault
Never leak sensitive API keys in frontend JavaScript. Your secrets are isolated in our MySQL vault and injected strictly at runtime inside a secure server-side Node.js VM sandbox.
Free Custom Domain Mapping
Connect your own domain (e.g., yourbrand.com) to any deployed project at zero cost. Our custom domain router detects incoming host headers and serves your app seamlessly.
