EiffelStudio 25.12 is available! A Modern Backend Platform Built for Reliability

by Administrator (modified: 2026 Jan 26)

Native PostgreSQL. Passwordless authentication. Cloud-ready libraries. All inside a contract-based development environment designed for systems that must hold.


“With EiffelStudio 25.12 we are deliberately strengthening Eiffel as a modern backend platform. Native PostgreSQL integration, passwordless authentication, and cloud-ready libraries are not add-ons — they are core requirements for building reliable systems today, and Eiffel now delivers them without compromise.”


EiffelStudio integrates databases, authentication, storage, and verification into a coherent backend stack — reducing glue code, runtime ambiguity, and long-term maintenance risk.
