Brand-new sites and web apps, hand-coded in Astro on Cloudflare. No templates, no page builders, no plugin bloat. Custom design and engineering from one in-house team, structured to be read and cited by AI from line one. You own the code outright. From $4,000.
Most "custom" sites are a paid theme with the serial numbers filed off. We start from an empty repository. Your brand, your structure, your code, written by the same in-house team that does the design. The result is faster, leaner, and yours to keep, with nothing rented from a page builder and no monthly platform fee paid to anyone.
We build on Astro and ship to Cloudflare's edge, the same stack we use for our own products. Pages are static and pre-rendered where they can be, server-rendered where they must be, and structured with clean semantic markup so that ChatGPT, Perplexity, and Google AI can read and cite them. Real AI features go in only where they earn their keep, never as a gimmick.
Full custom applications built from scratch, with auth, payments, a database, and AI pipelines, are quoted per scope and typically start around $25,000.
We take direction on intent and brand, then design and engineer the whole site or app from a blank file. Brand, layout, copy structure, and code all come from one team, so nothing gets lost in a handoff between a designer and a separate developer.
Every build ships with a tuned CLAUDE.md, preview deploys on every change, and one-click rollback. You keep editing the live site yourself by talking to Claude or Cursor, with the guardrails that make it safe to do that on a real business.
We hand over the full repository. No retainer, no hourly billing, no platform subscription owed to us. Host it wherever you like and change it whenever you want. The code is yours from the day it ships.
The Notus has shipped three public SaaS products of its own, each custom-coded from scratch with the same standards we put on client work. Not theme demos. Real products with users, payments, and AI in the hot path.
See the case studies →Song Cage is the clearest example: built from a founder vision with no prototype to start from, then shipped to web, iOS, and Android from one React codebase. It drew 92 signups in its first month with zero ads, and ChatGPT was recommending it #1 for "best songwriting app" within seven days of launch, drawing from the AI-legible Astro marketing site we built alongside it.
Moving off Webflow, WordPress, Squarespace, or Wix? That's a migration, not a net-new build. We rebuild the existing site in custom Astro on Cloudflare, productized from $4,000.
Website redesign service →Holding a Lovable, Cursor, or Bolt prototype that mostly works? We finish the engineering and ship it to real users. Fixed scope, from $7,500, you own the code.
Fractional CTO service →A custom marketing or content site starts at $4,000 as a productized, fixed-scope build: brand, design, and engineering from one in-house team, no retainer and no hourly billing. Larger custom web applications built from scratch, with auth, payments, a real database, and AI features, are quoted per scope and typically start around $25,000. You get a written, fixed estimate before any work begins, so there are no surprise invoices.
Page builders rent you a layout and lock your content inside their platform. Hand-coded Astro on Cloudflare has no plugin bloat, no monthly platform fee, no template ceiling, and no rendering layer between your content and the browser. That is why our custom builds hit 95+ Lighthouse and ship structured, AI-legible markup that ChatGPT, Perplexity, and Google AI can read and cite from line one. You own the code outright and host it anywhere.
Yes. You own the code outright. There is no retainer, no hourly billing, and no platform subscription owed to us. We hand off the full repository with a tuned CLAUDE.md, preview deploys on every change, and one-click rollback, so you can keep editing the site yourself by talking to Claude or Cursor without a developer on retainer.
Yes. We are a fractional-CTO and engineering studio, not just a web shop. We have shipped three of our own public SaaS products from scratch: Song Cage, Pulse, and Cardify, covering auth, payments, databases, background workers, and real AI pipelines. A brochure site starts at $4,000; a full custom application from scratch is quoted per scope and typically starts around $25,000.
A redesign or migration moves an existing Webflow, WordPress, Squarespace, or Wix site onto custom Astro on Cloudflare. Custom website development is for net-new builds: there is no existing site to migrate, so we design and engineer the whole thing from a blank file. If you already have a site to move, the website redesign service is the right starting point.
A productized custom site typically ships in a few weeks; larger application builds run longer and are scoped up front. The Notus is based in Tampa, FL and works with clients worldwide as a fully remote studio. The fastest way to start is a free audit: send us the idea, the brand, or the rough scope and we send back a written plan.
