AI-generated apps that pass security review
Stop waiting on engineering. Build production-ready internal tools with AI—on your company data, in your cloud.
Retool lets you generate dashboards, admin panels, and workflows directly on your data. Type something like “Build me a revenue dashboard on my Stripe data” and get a working app with security, permissions, and compliance built in from day one. Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.
The B compiler is a tool able to parse B models, and perform syntaxic and semantic analysis. It can also be used as a library, linked to applications manipulating B models (cross referencer, codegenerator, documentation generator, etc.).

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.
A LALR(1) Parser Generator for JavaScript written in JavaScript
JS/CC is a parser generator for JavaScript/ECMAScript, which is entirely written in ECMAScript itself. It produces LALR(1) parsers with integrated lexical analyzers. JS/CC can run as a website or be invoked from a console, and runs on several platforms.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
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.
IronMeta is an implementation of Alessandro Warth's OMeta metaprogramming system in C#. It provides a packrat parser generator that generates parsers for Parsing Expression Grammars that operate on arbitrary streams of objects.
...This file is compiled with your code to produce an executable. When the executable is run, it analyses its input to verify that its correspond to the grammar.
Styx is a scanner and parser generator designed to address some shortcomings of the traditional lex/yacc combination.
It has unique features like automatic derivation of depth grammar, production of the derivation tree including it's C interface which provides access to the abstract syntax tree, preservation of full source information and pretty printing to facilitate source-source translation, persistence to aid rapid interpreter writing.

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#.
This project will help you to expose C++ libraries to Python. pygccxml package is an object oriented framework for reading C++ declarations. pyplusplus package is an object-oriented framework for creating a codegenerator for boost.python library.
DBOW is a database compiler-compiler or front-end. It takes table definitions in a relatively high-level language and prepares C, C++, PHP, Perl (etc) functions for manipulating the database. It will also produce SQL table data for MySQL.
MUgen is an emulator generator which works in a way similar to yacc. It takes an input machine description and outputs a source file which is a fully implemented emulator of that system. This is the open-source system.
A parser generator based on parsing expression grammar rules. It generates code and accepts actions in LLVM Assembly rather than C like its predecessor, PEG, did.
A small educational compiler for a subset of the Pascal language. A native x86 machine codegenerator directly emits COM executables for MS-DOS. The compiler supports VGA graphics, floating-point arithmetic, etc. 32-bit Pascal source is provided.
Generate a parser at runtime from a collection of C++ objects. Concisely state a parser specification in ordinary C++ code. Learn from a parser generator with an object-oriented design.
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.
Complete LALR(1) parser generator and engine in PHP.
Complete LALR(1) parser generator and engine (like BISON or YACC) but it's all done in PHP, and the input grammar is easier and more maintainable. Write your actions in PHP. Generate PHP output code. Drive your parser with PHP. Wanna make a language?
CSP Canonical LR(1) Parser Generator. Includes lexer and parser generator. Supports all OS. Produces code as standard ANSI C++ w/ minimal STL and usable in commercial or non-commercial purposes.
