The actual product
Create a project, choose how it should think, and keep the work, settings, and code connected. This is a real capture from the Build codebase.

New in Build 1.7
Share a preview. Gather feedback. Make the revision. Let your client approve the version that addresses their request—all from the same project.
Review links open without a Build account. Each link stays on its saved version; live forms and connected services are tested in your working preview.

Build sites, portals, and internal tools. Give each client a branded workspace, a plan, and a monthly bill under your name.
Turn recurring workflows and ideas into tools without renting another locked platform for every experiment.

Model freedom
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.

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.

GPT-5.6 Sol pricing is promotional and currently listed by OpenAI as available through at least November 21, 2026.

Before you buy
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 guidesBuild 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.
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.
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.
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.
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.
Build runs on Cloudflare. You can try it locally first with no Cloudflare account, then deploy it into your own Cloudflare account when you are ready. Hosting, domains, storage, model usage, monitoring, and related third-party costs are yours.
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.
Yes. Choose the Agency edition and everyone gets their own login. You create client workspaces, invite people, assign plans with model and credit limits, and optionally bill clients through your own Stripe account. Projects are private by default. You can share a project with your team and hand editing back and forth, one editor at a time.
Your purchase covers the Build 1.7 source package with Personal and Agency editions, working forms, client reviews, approved-version publishing, domains, release history and website restores, reviewed GitHub imports, optional enquiry alerts and client handover. The commercial license and installation, upgrade and sharing guides are included. The included documentation defines the supported installation requirements and current release boundary.
Yes. Build 1.7.0 is in your downloads at no extra cost. Follow the upgrade guide before replacing files: preserve your projects and settings, apply pending migrations, and update the frontend and server together.
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.
