sLab is a white-label SaaS platform that lets agencies, freelancers, and entrepreneurs launch a fully branded client portal under their own domain. It bundles a CRM, invoicing, booking, blog, portfolio, email marketing, and AI content tools into a single multi-tenant Node.js / MongoDB stack.

Who is sLab built for?

Agencies, freelancers, consultants, small SaaS operators, and entrepreneurs who want their clients to use a portal that looks and feels like their own brand — not a generic third-party tool — without building it from scratch.

How is sLab different from other no-code platforms?

sLab is white-label first. Every tenant runs under their own domain, with their own branding, design tokens, copy, and integrations. There are no third-party logos in the UI, and tenant data is isolated per database, not multiplexed in shared tables.

How much does sLab cost?

Pricing is published on the sLab landing page. A free tier is available for early users; paid plans add custom domains, premium integrations, and higher-volume AI usage.

Can I use my own custom domain?

Yes. Every tenant can attach a custom domain. sLab provisions DNS, an Apache vhost, and an SSL certificate automatically. Outbound URLs (invoice links, meeting invites, tracking pixels) prefer the custom domain when present.

What is included with sLab?

Tenant-isolated MongoDB, client CRM, invoicing with Stripe and PayPal, calendar booking, real-time video meetings with transcription, a blog and portfolio builder, page builder with live design preview, AI content tools, email marketing, and a delegate/referral system for resellers.

Is sLab really no-code?

Yes for tenants and end-users. The platform exposes an admin design panel, copy editor, template store, and visibility toggles so tenants can configure their entire site without writing code. Developers can still extend the underlying MEVN stack when needed.

Does sLab support AI features?

Yes. sLab integrates with the madLadsLab AI API for image generation, LLM chat, content drafting, blog assistance, and meeting transcription summaries. Tenants can also wire in OpenAI or other providers via their own keys.

sLab is built and operated by Mad Lads Lab, a Colorado-based studio — and it's the same platform Mad Lads Lab uses to manage its own clients every day. Questions, custom integrations, or done-for-you setup are available through madladslab.com.

How hard is sLab to set up?

Most tenants are live on a free subdomain in an afternoon: pick a subdomain, set your branding, and load your content. Connecting a custom domain, email (SMTP), and payments takes a little extra integration, guided from the admin panel — and Mad Lads Lab can help or do it for you.
