SecureStartKit does not ship HIPAA-certified infrastructure. It ships the architectural patterns auditors look for: backend-only data access, RLS-isolated patient data, MFA-gated clinical-admin routes, and error handling that does not leak PHI.
Healthtech founders face a specific dilemma. Pre-revenue, HIPAA certification is unaffordable and arguably premature. Post-revenue, building on architecture that does not survive a compliance audit forces a rewrite of the data layer. The compromise is to ship the architectural patterns now and the certification later, on the same code.
The honest framing: SecureStartKit is not a HIPAA-certified stack. It is the patterns that make the certification path a checklist of vendor BAAs and policy documents, not a six-month architectural rewrite.
Each commitment below addresses a class of HIPAA Security Rule requirement. None of them substitute for legal compliance work, but all of them remove "we need to rewrite the data layer" from the certification path.
Patient data never reaches a Client Component. Server Actions with the service_role key handle every read and write after server-side authentication. The class of bug where AI-generated code drops the service_role key into a Client Component cannot apply, because the architectural commitment makes it impossible by construction.
Backend-only data access pattern →Every table holding patient-adjacent data ships with Row Level Security enabled and zero policies. The anon key cannot read anything. Service-role queries inside Server Actions are scoped to the authenticated user via getClaims. A missing policy on a new table fails closed (denies access) instead of failing open (leaking data).
RLS deny-all explained →Server Actions return ActionResult discriminated unions; unexpected errors land in a catch that logs server-side with full detail and returns a generic message to the client. Sentry payloads ship redacted by default. The error path does not leak PHI through error.tsx digests, server logs, or third-party SDK breadcrumbs.
Safe error handling →Routes that touch patient data require AAL2 (a verified second factor for the current session). The enforcement happens at the database, not just the UI: restrictive RLS policies require auth.jwt() to carry an aal2 claim, so even a forgotten Server Action check fails closed.
MFA + AAL2 enforcement →The template does not claim HIPAA compliance. It does not ship a Business Associate Agreement (BAA) with any vendor. Supabase offers a BAA on paid plans; Resend, Stripe, and Vercel each have their own posture. What the template ships are the architectural patterns that make the eventual HIPAA conversation a configuration change, not a rewrite. Talk to a compliance attorney before storing protected health information.
OWASP defenses by category →One purchase. Lifetime access. The patterns that survive a HIPAA conversation, shipped as code that already runs.
