White-label AI website builder

Give every customer an AI website builder inside your product.

Embed a white-label visual builder with an in-builder AI assistant and a built-in MCP server directly into your SaaS application. Your customers generate sections, rewrite copy, translate pages, and optimize SEO inside your design-system guardrails, running on your own AI keys with zero credit markups.

The AI chat panel sits beside the canvas, inside your brand.

An AI story for your customers, without broken layouts or token markups

Adding AI to your customer websites usually means choosing between fragile code generators that break on deploy or hosted builders that tax you on every prompt.

01

Structured blocks and design tokens, not raw HTML

Prompt-to-code generators spit out raw code that breaks mobile layouts and still has to be compiled and deployed. ChaiBuilder's AI edits structured JSON inside your registered React blocks and Tailwind CSS design tokens, so every change stays on brand and publishes live instantly.

02

Draft-first human approval and collision locking

When an AI agent connects via the built-in /api/mcp server, every content, SEO, and translation edit lands as a draft with a preview link and respects real-time page locking, so an agent never overwrites a human editor.

03

Bring your own AI keys with zero credit markup

Connect Vercel AI Gateway, OpenRouter, or your own enterprise OpenAI or Anthropic keys in your config. You pay your provider directly at cost, never a per-seat or per-prompt markup to us.

Sits right next to the visual canvas so non-technical customers can ask for copy rewrites, new sections, SEO metadata, or theme adjustments in plain language without filing support tickets.

Built-in MCP server (/api/mcp)

Lets power users and your onboarding team connect Claude, Cursor, or VS Code using 33 built-in tools, plus custom tools wired to your platform database, to translate pages, audit SEO, and build drafts from campaign briefs.

How the MCP server works

Built to sit inside your stack, not beside it

Hosted white-label builders keep your customers' websites on their cloud and tax you per site as you grow. ChaiBuilder runs inside your own application, so your customer data, your servers, and your margins stay with you.

Own your database

Bring your own PostgreSQL or SQLite database. All customer pages, registered users, revisions, and actions live inside your database alongside your core product records. ChaiBuilder has no access to any of it.

Own your infrastructure

ChaiBuilder is delivered as code you deploy on your own stack. There is no vendor-hosted runtime in the request path, and a lapsed license never takes a live customer site down.

One license, zero feature tiers

A single yearly Pro license unlocks the entire product: multi-tenancy, your brand in the builder, and the MCP server included. No feature flags, no per-site fees, no per-seat pricing, and no AI credits.

Ownership is not a plan tier or an add-on here. It is the architecture.

How is ChaiBuilder licensed and priced?

SaaS platforms license chaipro with one flat yearly fee for the entire platform, covering unlimited customer sites, quoted to your scale on the demo call. Build Services for initial integration, custom blocks, and site migration are scoped and billed separately. There are no per-site fees, no per-seat charges, no AI credit fees, and no feature tiers. If you only need a site or two, the open-source core (chaicore) is free under the BSD-3-Clause license.

What is the difference between the open-source core (chaicore) and Pro (chaipro)?

The open-source core (chaicore) is a single-site Next.js visual builder with SQLite page storage and runtime rendering. The commercial chaipro package adds everything a multi-site SaaS platform needs in production: multi-tenancy, PostgreSQL support, white-label branding in the builder, RBAC roles and permissions, revisions and restore, multilingual management, URL redirects, media management, the full in-builder AI assistant, and the built-in MCP server.

Our core product is not built on Next.js. Can we still use ChaiBuilder?

Yes. If your main SaaS runs on Rails, Laravel, Django, Go, or .NET, ChaiBuilder runs as a companion Next.js website service in your cloud (serving customer custom domains and the embedded editor) while its server-side data providers read live records from your existing backend API or primary database.

Can AI agents like Claude or Cursor update customer websites safely?

Yes. Every Pro license includes the built-in MCP server at /api/mcp. Users with the mcp:use permission connect Claude, Cursor, or VS Code using their personal API key. The agent operates strictly within that user's permissions, saves changes as drafts for human review before publishing, and respects real-time page locking so it never overwrites a page someone has open.

How does Bring-Your-Own-AI work?

The in-builder AI chat assistant connects directly to your own Vercel AI Gateway, OpenRouter, or custom AI provider credentials configured in your deployment, and MCP agents run on the AI subscriptions your team or customers already use. ChaiBuilder never sits in the middle or charges AI token credits.

How do we validate fit before signing a platform contract?

Every engagement starts with a 30-minute architecture and product demo call, followed by a scoped pilot where we integrate ChaiBuilder into your app on a small set of customer sites. Your engineers can also inspect the open-source core (chaicore) on GitHub at any time.
