Enclave: multi-tenant client portal with DB-level isolation - Sell Project

Enclave is a deployed multi-tenant client portal where tenant isolation lives in the database through Postgres row-level security, not just in application code, so a query that forgets its account filter returns empty instead of leaking another tenant's data. The flow runs end to end: accounts, authentication, a per-account dashboard, documents with signed per-account blob URLs, a schema visualizer, and an RLS policy showcase that makes the isolation inspectable and testable rather than something you take on trust. The live demo is seeded with three accounts you can click through and compare. Stack: Next.js, React, TypeScript, Tailwind CSS, shadcn/ui, PostgreSQL with row-level security, deployed on Vercel. A second variant runs the same idea on Drizzle ORM and better-auth, with migrations included. Best for legal client portals, document-filing tools, financial-intelligence dashboards, compliance and audit portals, and investor or accountant portals, or any B2B SaaS that gives every client a login and cannot afford a cross-tenant leak. It saves the 40 to 80 hours of designing, building, and proving tenant isolation, the part most teams get subtly wrong. What transfers: a single-buyer exclusive license, the GitHub repository transferred to you, the seed script, a HANDOVER.md and LICENSE-TRANSFER.md, and 30 minutes of email Q&A within 14 days of sale.
