The platform combines linguistic data management with web-based technologies, offering an integrated suite of software modules-including online dictionaries, spell-checkers, corpus alignment systems, linguistic maps, and multimedia archives-tailored for under-resourced and dialectally fragmented languages. Unlike standard language technology pipelines designed for dominant languages, Small Codes supports linguistically diverse input and community-led data models. It operates through a federated, semi-industrial development model, balancing long-term sustainability with flexibility for academic and institutional partners. This paper outlines the system architecture and core functionalities of Small Codes, presents selected implementation scenarios, and discusses its contribution to digital heritage and computational dialectology.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Web-based interaction; Information systems → Relational database model; Applied computing → Language translation; Social and professional topics → Cultural characteristicsHuman centered computing → Webbased interactionInformation systems → Relational database modelApplied computing → Language translationSocial and professional topics → Cultural characteristics10.2312/dh.202533319 pages
