Platform
Platforms and vertical SaaS
Your members or customers each get a site inside your product, on your data, under your brand. One install runs them all, kept current by your team, your members and their agents.
For platforms that run many websites
The Website Builder for Agents and Humans.
Owned by You.
Give every member of your platform a site, built from your data, inside your own Next.js app, under your brand. Whoever runs a site, your team or your members, edits it visually or hands the work to an AI agent through the built-in MCP server, and publishing never needs a build.
For platforms running many sites: white label, multi-tenant, custom integration.
Real code you control, not a walled garden.

The website module for your platform
Every member, customer or tenant gets a site generated from your data, inside your own Next.js app, on your own database, under your brand. Websites become one more module of the product you already run.
Sites from your data
Bind blocks to the records you already hold: listings, inventory, locations, staff. Sites are built from your data, not copied into a vendor's.
One install, many sites
Multi-tenancy is built in. One deployment serves every tenant's sites, each kept separate, on infrastructure you control.
Your brand, every site on brand
Your logo and colors inside the builder, with no ChaiBuilder branding. Design tokens keep every tenant's site inside your design system.
Publish without a build
Change one page and it is live. No rebuild of every site, no deploy queue. Pages revalidate on publish.
Built for vertical SaaS and multi-site platforms: real estate, automotive, insurance, clinics, franchises, and agencies running many client sites.
Agents draft the changes. People approve them.
Whoever runs a site, your team or your customers on their own sites, can hand the busywork to an AI agent in Claude, Cursor or VS Code, or ask the chat panel in the builder. Every change lands as a draft a person checks, fixes and publishes.

Translate the pricing page into German and show me a preview
get_block_translationsupdate_block_translations
The German translation is saved as a draft. Nothing is live yet.
Want me to publish it?
- 01
Ask
Anyone with an account and permission to use agents asks from their own AI tool through the MCP server, or from the AI assistant inside the builder. One page or two hundred.
- 02
The agent drafts
Edits, translations and SEO land in drafts with a preview link. The agent works as the person whose key it holds, with exactly their permissions.
- 03
A person finishes
Open the draft in the visual builder and fix what needs an eye. The builder shows which pages AI is editing, and an agent never overwrites a page someone has open.
- 04
Publish, no deploy
Approve and it is live. Revisions mark every change an agent made, so anything can be rolled back.
Developers set it up once. Everyone else runs the sites.
Low-code, not no-code. Your developers keep full control of the stack, and the people closest to each site make the changes, with agents alongside them.
Your developers
Integrate once. ChaiBuilder is a plugin in your Next.js app: add custom blocks, bind them to your data, override pages and routing, and add MCP tools for your agents. No closed black box.
Your team
Account managers and designers build and fix pages on the visual canvas, review what agents drafted, and publish. No tickets to engineering for a changed phone number.
Your members
Give members the edits they should make, and nothing more. Roles and permissions decide who can edit, who can publish and who can connect an agent.
Websites are part of your product. Hosted builders can't be.
Most platforms end up with one of two bad options: rent a website builder that lives outside their product, or hand-code every site and rebuild them all on every change.
Outside your product
Hosted builders keep every site on their cloud and behind their dashboard. Your members' data ends up split between your product and someone else's.
Locked to their terms
Their pricing, their features, their roadmap. When they change the rules, every site you run changes with them.
Code that rebuilds everything
Hand-built sites put every fix through a developer. On a static build, one change can mean rebuilding every site you run.
Ownership by design
Own everything you build
Hosted builders rent you a website on their platform. ChaiBuilder runs inside your own app, so the data, the servers and the full feature set stay with you.
01Own your data
Bring your own database: SQLite or Postgres. All website content, registered users and actions live in your database. ChaiBuilder has no access to any of it.
02Own your infrastructure
ChaiBuilder is delivered as code you deploy on your own stack. You host it, you run it. There is no vendor-hosted runtime for your site.
03No feature tiers
A Platform license unlocks the entire product, the MCP server included. No feature flags, no per-seat pricing, nothing to upgrade into.
Ownership isn't a plan tier or an add-on here. It's the architecture.
Everything in the Platform license. No tiers.
Every capability ships with every Platform license. No add-ons, no per-seat pricing, no AI credits.

Questions platforms ask
Anything else, bring it to the demo call.
How is the Platform license priced?
One yearly license for your whole platform, however many sites it runs, quoted to your scale on the demo call. Build services for integration, migration and custom work are billed separately. No per-site fees, no per-seat pricing, no AI credits, no feature tiers, so your margin per site is yours as you grow.
Do we host it, or do you?
Either. Self-host it on your own infrastructure and database, or run it as a managed White Label Solution that we host for you. If you already have an application, the builder can be embedded inside it as a Custom Integration.
What do build services cover?
Integrating ChaiBuilder into your app, custom blocks, binding pages to your data, migrating your existing sites, and rollout support. Billed hourly or at a fixed price per scope, so a team without spare front-end developers can still go live.
Can AI agents maintain our sites?
Yes. The built-in MCP server lets Claude, Cursor, VS Code or any MCP client edit, translate and publish pages with a person's own permissions. Edits land as drafts for review, and agents run on the AI tool you already pay for. How agents connect.
Can our developers try it before the call?
Yes. chaipro has a 30-day trial with no credit card and no email, from the get-started page. The open-source core is free to read and run too.
We only need a site or two. Is this for us?
Use the open-source core. It is free, BSD-3-Clause licensed, and runs in your own Next.js app. The Platform license is for teams running many sites. Start with open source.
