No hidden middle layer
You choose every layer.
Build gives you the product surface. You decide what powers it, where it runs, and how it makes money.
Model
Use the models you choose.
Provider
Bring your own connection.
Code
Change every layer.
Cloud
Run it in your account.
Business
Keep the customer relationship.
One codebase, different businesses
Build it for yourself. Or sell it to someone else.
The point is not one more app in your stack. The point is a foundation you tailor to your offer—from internal tool to customized client service to differentiated vertical software.
AGENCIES
Sell client apps
Build sites, portals, and internal tools. Deliver the result under your brand and price the work your way.
OPERATORS
Power your business
Turn recurring workflows and ideas into tools without renting another locked platform for every experiment.
CRM BUILDERS
Embed the experience
Add an app-building surface to the CRM or client portal you already sell and support.
PRODUCT FOUNDERS
Create a vertical builder
Narrow Build to a niche, meaningfully change the workflows, experience, and defaults, then turn that differentiated implementation into your own product.

Model freedom
Pick the brain. Keep the product.
Use a curated OpenRouter picker, connect native OpenAI or Anthropic keys, or use the supported Codex subscription path. Build is designed around provider choice—not a permanent model lock-in.
Your credentials, your provider billing
Model availability, subscriptions, limits, and usage charges remain subject to each provider's terms.

Simple model economics
Pick four things. See the picture.
Choose a model and a simple client-work scenario. We will estimate the provider usage—Build never adds a per-project fee or takes a percentage of your sales.
Your example
Four quick choices. No token math.
Balanced value
“Typical” assumes 80 AI requests per project, averaging 16K input and 3.5K output tokens per request. You can change models at any time.

What that means
One $2,500 project covers Build 4.2×.
About $5.92 in model usage per project.
Build takes $0 per project and 0% of your revenue.

Illustrative estimate only—not a quote, profit calculation, guarantee, or earnings claim. Your revenue, token use, labor, hosting, support, taxes, payment fees, refunds, and other expenses will vary.
Model spend estimates metered API or provider usage. Codex subscription sign-in follows the customer's subscription limits instead of this token-cost estimate.
Rates checked September 1, 2026. Sources: OpenAI, Anthropic, and OpenRouter. Rates and availability can change.
GPT-5.6 Sol pricing is promotional and currently listed by OpenAI as available through at least November 21, 2026.

Before you buy
FAQ.
The shortest honest answers about ownership, technical requirements, commercial use, and refunds.
Build setup guides, troubleshooting, and client handoff resourcesRead our AI coding and software ownership guides01What is Build?
Build is a self-hosted AI app and website builder sold as editable source code. It includes a visual workspace, live previews, project history, model and provider choices, and export paths. You deploy it to your own infrastructure and connect your own services.
02Why would I buy Build instead of using Claude Code or Codex directly?
Claude Code and Codex are excellent coding agents. Build is the product layer around the building experience: a visual web workspace, live preview, project history, model/provider choices, export paths, and a codebase you can brand for your own customers. You can still use coding agents to extend Build—the choice is not either/or.
03Is this a hosted SaaS subscription?
No. You are buying a self-hosted codebase. You install it into infrastructure you control, connect your own services, and are responsible for operating it. DevLaunch is not metering every project or taking a percentage of your revenue.
04Can I resell it, rebill it, or include it in my CRM offer?
Yes—you can charge for products and client solutions you build with it, including a customized experience inside your CRM offer. You must meaningfully adapt Build to your market, workflow, integrations, or customer experience; changing only the name or logo is not enough. You may not resell, sublicense, share, or redistribute the Build source package itself—or a substantially unchanged clone—as a competing codebase, template, or download. The supplied commercial license will define the complete terms.
05Do I get free AI usage with Build?
No. You choose and pay the model provider. Bring an OpenRouter, OpenAI, or Anthropic API key, or connect a supported Codex subscription flow. Provider limits, terms, and usage fees still apply.
06Where does Build run?
Build is being built around Cloudflare infrastructure. You deploy it into your own Cloudflare account and connect the resources required by the installation. Hosting, domains, storage, model usage, monitoring, and related third-party costs are yours.
07Do I need to be a developer?
You do not need to write every feature from scratch, but this is still a codebase you operate. You should be comfortable following technical setup instructions or working with a developer or coding agent when you customize, secure, deploy, and support it.
08What is included with Build 1.0?
Your purchase covers the Build 1.0 source package, the included commercial license, and installation and release documentation. The included documentation defines the supported installation requirements and current release boundary.
09What is the refund policy?
All sales are final. Build is a digital source-code product, and access cannot be meaningfully returned after delivery. Please review what it is, what it is not, and the technical requirements before purchasing.
