How do I build a secure client document portal?

This Reflex template handles uploads, downloads, review, and approvals with separate client and internal views. Documents carry status, owner, category, due date, and version, and an activity timeline records comments and decisions.

How do I make sure clients only see their own documents?

Document access is permission-aware and scoped to the signed-in client, and the same check belongs in the handler that serves a file so a direct request cannot bypass the UI. Put the app behind your existing authentication provider.

What's a good alternative to SharePoint or ShareFile?

For client files those products are broad and priced per user, which is heavy when you need one focused portal for clients to exchange documents. This template gives you exactly that flow, branded and hosted by you.

Can it store files in S3 and connect to e-signature?

Yes. Document metadata is ordinary Python state, so real storage slots in behind the same permissions and review flow. Files typically go to S3 or equivalent object storage with metadata in Postgres through SQLModel, and teams commonly trigger DocuSign from the approval step.

About This Template

Build a production-ready document portal with Reflex and Python. This template is designed for teams sharing files, forms, and records with clients or internal users who need a usable app structure for client portal, secure uploads, document review, and file approvals, not a static mockup. The app pattern includes a focused dashboard, searchable tables, detail views, validated forms, status-aware actions, empty and loading states, and database-ready state management. Use it as a starting point for a client portal, document management portal, secure document upload portal, and file portal while keeping full control of the Python codebase. Ahrefs research informed the SEO language for this page, with target terms such as document portal (250 US searches/mo); client portal (11K US searches/mo). The copy is written to match real search intent while describing the app a builder can actually generate and customize.
