White-label platforms, your customers ship their brand, your team owns the engine.
White-label is a different product than the one most SaaS teams started with. You're not selling a SaaS to customers anymore; you're selling a platform that lets your customers run their own SaaS. We build the parts that change (custom domains, theming, per-tenant assets) and harden the parts that stay (tenancy, billing, audit).
What we build
Custom domains with automated cert provisioning
Customers point a CNAME at our edge; certificates provision via Let's Encrypt in under a minute. The domain layer is observable, operators see which customer's domain is provisioning, healthy, or failing renewal. No manual cert juggling.
Theming via tokens, not CSS overrides
Customers set brand colors, fonts, and logo through an admin UI. The tokens flow into the design system at render time; the rendered product picks them up consistently across every screen. No 'one screen forgot the override' bugs.
Per-tenant assets served from a CDN
Logos, favicons, email signatures, OG images, uploaded once per tenant, served from a CDN with appropriate cache busting. The auth flow shows the tenant's logo before the user signs in; emails leave with the tenant's wordmark.
Email + transactional comms in the tenant's voice
From-address per tenant (DKIM + SPF managed), reply-to routed through the platform, template branding picked up from tenant tokens. Customers feel they're emailing the tenant, not the platform.
Isolated data with shared infrastructure
Per-tenant row-level scoping in Postgres, separate object storage buckets, separate audit streams. The infrastructure is shared; the data is not. SOC 2 reviewers see the boundary; one tenant's compromise doesn't reach the others.
Operator dashboards that span tenants
The platform operator (you) sees the cross-tenant view: who's onboarded, who's at the brink of churn, who's hitting a usage ceiling. The tenants see their own surfaces only. Two product UIs, one codebase.
Where this fits
You're selling to enterprises who want their customers (or franchisees, or partners) to use the product under their brand.
Your product is being adopted by agencies who want to deliver it under their own name to their clients.
Your multi-tenant SaaS is at the scale where 'white-label tier' has become a real sales motion and the existing tenancy can't carry the branding.
