Frequently asked questions

Everything about claiming your always-free subdomain.

Is the subdomain really free?

Yes. Every devs.surf subdomain is always free, forever. There is no credit card, no trial period, and no hidden fees — claim a name and it stays free.

Will it stay free forever, or become paid later?

It stays free. Devs.Surf is a free domain service for developers; your subdomain and DNS management remain free for as long as you use them.

What DNS records can I manage?

You can manage A, AAAA, CNAME, and TXT records with realtime propagation, and point your free subdomain at Vercel, Netlify, Firebase, GitHub Pages, Cloudflare Pages, or your own server.

Do I need an account to claim a free domain?

You just sign up with email or Google, search an available name on devs.surf, and claim it in seconds — completely free.

Can I use my free subdomain with Vercel, Netlify, or Firebase?

Yes. Add the CNAME, A, or TXT records your host provides (for example a Vercel, Netlify, or Firebase verification record) and your free devs.surf subdomain will point straight to your deployment.

AI_AGENT_CAD_COMPILER

Parametric CAD Synthesized by Autonomous AI Agents

Terrarium replaces manual 3D drafting with an independent Rust geometry engine (not OpenSCAD itself, but fully compatible with OpenSCAD syntax and standard libraries). Autonomous agents interpret physical constraints, iterate on parametric geometry, and verify watertight models in realtime via sub-second JIT compilation and hardware GPU rendering.

Terrarium CAD Workbench — Autonomous AI Parametric Engine

CLICK TO EXPAND HIGH-RES (3200x2000)

01 // AGENT PIPELINE

LLM coding agents generate, inspect, and repair mechanical parts (housings, snap-fits, hinges) autonomously without tedious CAD sketching.

02 // RUST CSG JIT & GPU RENDER

Sub-100ms Manifold CSG kernel in Rust with native OpenSCAD language support, realtime viewport feedback, and hardware GPU rendering: delivers 3-10x faster execution than OpenSCAD Nightly and 50-100x faster than legacy OpenSCAD.

03 // 3MF & STEP EXPORT

Outputs guaranteed watertight production meshes ready for slicing directly on Bambu Lab 3D printers and CNC fabrication machines.
