Softr

Build me a client portal to replace Softr: one portal for my own clients, not a portal builder. Requirements: - Node + Express + nunjucks, server-rendered; data stays in Airtable via its REST API (base ID and token in .env) so records keep being edited there. - Magic-link login: a client enters their email, gets a signed link via Resend (secret in .env); sessions in signed cookies. Allowed emails live in an Airtable Clients table. - Each client sees only rows linked to their client record: a list view with the columns named in views.json, and a detail view per record. - One submission form that appends a row to a chosen table, with file upload passed through to Airtable attachments. - A role flag on the client record (client vs admin); admins see all rows. - Cache Airtable reads for 60 seconds to stay under rate limits. - Runs on my VPS behind HTTPS; no telemetry, no third parties beyond Airtable and the email sender. - Out of scope: a drag-and-drop page builder, payments, and memberships. Pages are defined in config files, that is the builder. - README: Airtable token scopes, expected table and field names, and email sender setup.
