Ship AI Apps Faster with Vertex AI
Go from idea to deployed AI app without managing infrastructure. Vertex AI offers one platform for the entire AI development lifecycle.
Ship AI apps and features faster with Vertex AI—your end-to-end AI platform. Access Gemini 3 and 200+ foundation models, fine-tune for your needs, and deploy with enterprise-grade MLOps. Build chatbots, agents, or custom models. New customers get $300 in free credit.
A lexical analyzer generator that makes the class source code.
ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.
SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle.
Run everything from popular models with on-demand NVIDIA L4 GPUs to web apps without infrastructure management.
Run frontend and backend services, batch jobs, host LLMs, and queue processing workloads without the need to manage infrastructure. Cloud Run gives you on-demand GPU access for hosting LLMs and running real-time AI—with 5-second cold starts and automatic scale-to-zero so you only pay for actual usage. New customers get $300 in free credit to start.
JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It has some not so usual features like negation in regexps and nested input streams. Also reads JLex specifications unchanged.
Coco/S is a compiler generator that takes plain EBNF grammar files and features a SAX style call back API. It is written in Java and produces a Java Scanner (Lexer) and Parser for the language described by the input grammar.
Coco/S is a branch of the 2010/11 release of Coco/R for Java.
While Coco/R takes an attributed grammar file, Coco/S has a callback API. This has the advantage of a clean separation between grammar (EBNF) and Compiler/Interpreter.
This is a compiler for the 'pseudocode' Haggis used by the Scottish Qualifications Authority for specifying pseudocode. The compiler is implemented in Java.
JTools provides some useful tools and utilities for Java 5.0 development.
Beneath some smaller utilities we have:
a (Ant like) DAO framework (also including XML Repository) and
a (JSP like) general purpose template generator and execution framework.

Lapg is the combined lexical analyzer and parser generator, which converts a description for a context-free LALR grammar into source file to parse the grammar. Generates code for Java, Javascript, C, C++ and C#.
lightJacc is a small but strong grammar parser generator. It adopts a parsing strategy of its own: dynamic concurrent parsing -- which made it much stronger than LR or LL family CCs (YACC, ANTLR, etc), but still keep good performance.
ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
Covra is a project to help design compilers. C3 is a tool specialized on the easy design and construction of ASTs, it is independent of the compiler compilers or parser generator that is used. It generates Java and C# code. Require JRE 1.6.0.
BNF for Java is a BNF Compiler-Compiler, or Parser-Generator. It implements ISO Standard Backus-Naur Format, using Java. BNF allows you to create a syntax, or a complete language, to parse your data source. Your custom Java extensions generate output.
Berkeley Yacc is an LALR(1) parser generator. Berkeley Yacc has been made
as compatible as possible with AT&T Yacc. Berkeley Yacc has been extended
to generate Python, Perl and Java code.
EGG is a development tool for fast and easy realization of XML to plain-text tranformations.
It's similar to XSLT, Velocity or JSP but emphasises source-code generation in a model-driven, generative development-process. For Windows or Unix with Java.
classgen is a Java class generator. It produces classes for abstract syntax trees in compiler frontends from simple and compact specifications. Generated classes have builtin support for the Visitor design pattern.
It is basically an education Java compiler we are developing - just to gain an insight into the workings of a compiler. It is NOT meant for commercial use!! Its written in Java and uses ANTLR parser generator and the Byte Code Engineering Library extensiv
Blade Language Developer (or Project Blade for short) is a toolkit for creating domain specific or general programming languages. The toolkit offers a language for describing grammars, and templatable parser generator.
