Open Archiver
Open Archiver is a secure, sovereign, and open-source platform for email archiving and eDiscovery. It provides universal ingestion from IMAP, Google Workspace, Microsoft 365, PST files, mbox files, and zipped .eml files. Emails are stored in standard .eml format with deduplication, compression, and optional AES-256 encryption at rest. Features include full-text search across emails and attachments (PDF, DOCX, etc.), thread discovery, file integrity verification, immutable audit trails, role-based access control, and pluggable storage backends (local or S3-compatible). Built with SvelteKit, Node.js, PostgreSQL, Meilisearch, and BullMQ.
