A document service by a3s.app
Docs secure document portal
Tenant-aware delivery on your wildcard subdomain with protected file access. Documents are resolved per client and served only through signed links.
Everything you need to host documents
A lightweight, no-frills approach to sharing HTML documents online.
Tenant Storage
Store client files in storage/tenants/{tenant}/documents so content is scoped by subdomain.
Wildcard Subdomains
Requests resolve tenant context from the host (for example, kitcarson.domain.tld) before serving data.
Signed File Access
Raw files are delivered through signed API URLs instead of public static paths.
Private by Default
Direct /documents public access can be blocked, preventing cross-tenant file exposure.
