Postfold

An open-source shared support inbox, organized around your projects.

A familiar email interface with project folders, conversation tracking and contact context. Built with TanStack Start, React, NestJS and PostgreSQL.

Highlights

• Shared folder trees, colors, drag-and-drop ordering and sorting.
• Shared labels: create, edit, filter and assign individually or in batches.
• All-message or threaded view, saved newest/oldest ordering and direct reply controls.
• Read/unread and workflow states, individually or in batches.
• First-gesture drag-and-drop and batch actions that keep the list stable.
• Multiple thread participants, individual contact notes and saved rich drafts.
• Personal/team email templates, HTML signatures and a team management dashboard.
• Compact rich text editor with an expanded writing mode, previews and persistent attachments.
• Viewport layout with fixed headers and independent panel scrolling.
• French/English interface, IT support demo, search and automatic refresh.
• Optional IMAP/SMTP connection, encrypted credentials and duplicate-send protection.
• Complete mail archives, attachment-preserving downloads and recovery after external deletion.
• Keycloak SSO with individual sessions and client-role access control.
• Shared teammate assignment and a conversation activity history with verified SSO authors.

Run locally

Requires Node.js 24+, pnpm 10 and Docker Compose.

pnpm install --frozen-lockfile
pnpm dev

Open http://127.0.0.1:3002. PostgreSQL and the separate API start automatically.

Default demo: fictional IT support data, sending disabled and simulated presence. To use a real account, follow mailbox setup. Enable Keycloak SSO for individual access. Notes and drafts remain browser-local; offline sync is planned.

Deploy and update

Public releases include compiled builds, Docker images (AMD64/ARM64) and deployment configuration. Follow Docker deployment and updates, or use Linux/systemd. CI validates real mail, Keycloak, rich authoring, responsive layouts and production containers before publishing.

Development

pnpm typecheck
pnpm test
pnpm build

With the dev server running and agent-browser installed, pnpm test:drag checks native drag-and-drop; pnpm test:viewport checks 13 screen sizes, long threads, saved sorting and participant notes.
