ScalaSql review
A typed Scala query library with CRUD, joins, transactions, and ZIO integration.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ScalaSql gives Scala developers a library for querying SQL databases through typed table descriptions and familiar collection-style operations. It covers selecting, inserting, updating, and deleting records, along with joins and transaction handling. Its static type safety and ZIO integration make it a fit for Scala teams that want database access within a typed Scala API, especially teams already using ZIO. The project specifies Scala 3.6.2 or later, so it is not aimed at applications on older Scala versions.
Database support spans PostgreSQL, MySQL, SQLite, Microsoft SQL Server, and H2. The library also offers transactions, savepoints, an asynchronous transaction API, and a raw SQL escape hatch. That mix provides useful coverage for common query work while retaining an option for SQL that does not fit the library's higher-level query interface. ScalaSql is open source and self-hosted, so it can suit teams that prefer to manage the library as part of their own application stack rather than depend on a hosted query service.
The tradeoff is project maturity: ScalaSql describes itself as relatively new and cautions that users may encounter bugs or missing features. Its listed support channel is community support, which may not meet teams seeking vendor-backed assistance. Choose it if typed Scala queries, ZIO effects, and support for the listed databases match your stack and you can accommodate an evolving project. Teams that need a mature feature set or a different support model should compare alternatives before adopting it.
