1. jOOQ

   1 101 6,508 9.8 Java

   jOOQ is the best way to write SQL in Java

   

   Project mention: How to Make Websites That Will Require Lots of Your Time and Energy | news.ycombinator.com | 2025-07-28

   at the very least, if you are really writing lots of INSERTs by hand I bet you are either not quoting properly or you are writing queries with 15 placeholders and someday you'll put one in the wrong place.

   ORMs and related toolkits have come a long way since they were called the "Vietnam of Computer Science". I am a big fan of JooQ in Java

   https://www.jooq.org/

   and SQLAlchemy in Python

   https://www.sqlalchemy.org/

   Note both of these support both an object <-> SQL mapper (usually with generated objects) that covers the case of my code sample above, and a DSL for SQL inside the host language which is delightful if you want to do code generation to make query builders and stuff like that. I work on a very complex search interface which builds out joins, subqueries, recursive CTEs, you name it, and the code is pretty easy to maintain.

10. Telosys

    8 2 179 6.6 Java

    Telosys Command Line Interface - Code Generator for any language with any framework

    

    Project mention: Dashboard of open source low-code tools | dev.to | 2024-11-24

    In fact, there are a few. For instance, Telosys (that we also covered here). But Telosys defines itself as a "lightweight and pragmatic code generator", not as a low-code tool. Once again, the diverse terminology in our area makes a small domain even smaller and hides useful tools from potential users that are using the "wrong" keywords. To read mode about the relationship between the low-code and model-driven communities, take a look at our work on a Metascience Study of the Adoption of Low-Code terminology in Modeling Publications, which we are now updating and extending as I still believe it's an important discussion to have in our community.
