Software
Software developed by the TU Delft Programming Languages group.
Language Engineering
- Spoofax: a language workbench providing an IDE for the development of language definitions and the automatic generation of IDEs for defined languages
 - SDF3: a modular formalism for syntax definition that integrates lexical and context-free syntax.
 - Stratego: a language for the specification of program transformation systems based on the paradigm of rewriting strategies.
 - NaBL2: a constraint-based language for definition of type systems
 - Statix: a newer constraint-based language for definition of type systems
 - FlowSpec: a language for specification of data-flow analysis
 
Build Systems
- PIE: Pipelines for Interactive Environments
 
Proof assistants
Compilers:
- Agda: A dependently typed programming language and proof assistant
 - Agda2Hs: Translating reasonable Agda to readable Haskell
 
Libraries:
- UniMath: This Coq library aims to formalize a substantial body of mathematics using the univalent point of view
 - Agda Generics: A library for datatype-generic programming in Agda
 
Verification tools for concurrency
- Fency: A LLVM compiler pass for enforcing robustness of concurrent programs
 - Lasagne: A static binary translator for weak memory architectures
 
Web Programming
- WebDSL: a web programming language
 - IceDust: A language for data modeling and incremental computing of derived values
 
Applications built with WebDSL
- WebLab: an e-learning system for programming education
 - conf.researchr: a domain-specific content-management system for conferences
 - researchr: a web-based bibliography management system
 - EvaTool: course evaluation workflow
 - My Study Planning: a tool for study program planning
 - YellowGrass: a web-based issue tracker
