# Project foundations Explore repositories by project goal or target platform. Compare business applications, app foundations, game engines and supporting libraries before choosing your starting point. Page 1 of 1 ## Paperless-ngx Business application A searchable document-archive foundation with OCR, metadata and automated document processing. ### Why we recommend it We recommend Paperless-ngx when the core goal is turning incoming scans and files into a well-organized, searchable archive. ### When to choose it - Build an invoice archive, a company document intake system or a search service connected through its API. ### What to consider - A searchable archive is not automatically a multi-stage approval system. Validate access rules, OCR quality and your retention and backup requirements with representative documents. ### Start with this project Import a representative document batch and test classification, search, permissions and an API integration.

Storage growth, backup recovery and access audits need their own design. - The project warns that development builds are unstable; choose a stable release for deployment. ### Start with this project Model one document review with two roles, a revision and a webhook to a business system.

Complex approval portals and transactional business records are additional scope beyond document organization. ### Start with this project Test intake from your actual scanner or mailbox and measure search quality on representative files.

Verify features against the selected OSS version and budget for its supporting services and migration path. ### Start with this project Install the chosen OSS release in a test environment and validate OCR, search and access with your own sample documents.
