AppM Build Automaiton is an open source and automated software application that is used to construct and build projects on different operating systems and using different development environments. General principles of implementation: -Each project must have a Build Project File, containing the necessary information on the construction of the project. For example, a unique name of the project, dependence on other projects and libraries, methods of construction, etc. Thus, the entire repository should be marked by the project description files to provide unambiguous information on the projects and their dependencies. - AppM Build Automaiton must be able to perform different actions (project construction, external applications launch, file copying, etc.) which are needed to build a -product. - All operations with projects should be carried out on the basis of information that build tool derives from the project description files.
A unified compiler-construction meta-language designed to define and build programming languages within a single .mor file. By describing tokens, grammar rules, semantic analysis, and code generation in one place, developers can produce native Win64 or Linux64 binaries via a built-in Zig/Clang pipeline.
NitroPascal is a full-featured Object Pascal compiler built entirely on top of Parse() - the compiler construction toolkit. It exists to prove a point: a complete, production-quality language can be built with Parse() without touching a parser generator, a lexer generator, or a custom pipeline.
Parse() is a comprehensive Delphi-based toolkit designed to streamline the entire process of compiler construction. By providing a unified API, it allows developers to define a custom programming language’s syntax and logic within a single configuration object. The system manages the complex transition from source text to native binaries.
NitroPascal is a new data/object oriented programming (DOOP) language based on Pascal / Delphi. In development is: - compiler (npc), - IDE NitroEDitor (NED).
A fluent, type-safe SQL query builder for Delphi 12+. Supports multiple SQL dialects, parameterized queries, composable query construction, and database-independent execution through extensible providers. Includes FireDAC integration and a comprehensive test suite.
A graph‑based workspace for linking documents and data—across local and shared knowledge—so you can query, explore, and build reports with clarity. Under construction!
FreeTower is a building construction and management simulator. It is designed to be portable and run on several desktop and PDA operating systems, and of course, be fun to play =)
The package customdrawn.lpk is an under construction package containing all kinds of custom drawn components for Lazarus. Read more about it in Lazarus Custom Drawn Controls .
PressObjects is a software development kit (SDK) composed of several frameworks that assist the construction of object oriented applications. The code is compatible with Delphi-Win32 and Free Pascal compilers.

QUICK, which stands for Quick User Interface Construction Kit, is a Delphi library which aims at accelerating the development of graphical user interfaces as well as giving developers the possibility to create beautiful GUI's for their software.
SimpleBasic is a very simple programming language for easy and rapid crossplatform software development. It includes most constructions from classic BASIC but has a more easy and flexible syntax.

A curated list of awesome Delphi/FreePascal/(any)Pascal frameworks, libraries, resources, and shiny things. Inspired by awesome-... stuff. Open source and freeware only!
Quick development library (AutoMapper, LinQ, IOC Dependency Injection, MemoryCache, Scheduled tasks, Json and Yml Config and Options pattern, Serializers, etc) with crossplatform support for Delphi/Firemonkey (Windows,Linux,OSX/IOS/Android) and freepascal (Windows/Linux).
Cassotis IME - a native Delphi/TSF Chinese Pinyin IME for Windows 10/11. 言泉输入法 —— 基于 Delphi/TSF 的 Windows 10/11 原生开源中文拼音输入法，支持全拼、简拼、六种双拼，并通过语料训练的本地语言模型与神经重排提升输入质量。
The Deepseek API wrapper for Delphi leverages Deepseek’s advanced models to deliver powerful capabilities for seamless and dynamic conversational interactions, including a model optimized for reasoning, and now also supports running local models through an LM Studio server.
Codrut Fluent Design System is a suite of VCL components for Delphi made to mimic the design language of Windows 11. These are all standard components made to work best with each other.
Fast and simple implementation of Protocol Buffers for Delphi. Now we support code generation for the classes. Next, we plan to add reflection and records using memory regions.
Delphi wrapper for the Google Gemini API: stateless generation and agent workflows with multimodal, streaming, persistent interactions, structured outputs, vector search, batch, image/video generation, and grounding (Search/Maps).
IAMClient4D is a Delphi client library for integrating applications with Keycloak, providing full OAuth2/OpenID Connect support (including PKCE), token and user management, and a lightweight asynchronous task framework (Async.Core) for thread-safe operations across VCL and FMX.
The Hugging Face API wrapper for Delphi leverages cutting-edge models to deliver powerful features, including object detection, music generation, text classification, sentiment analysis, image segmentation, speech-to-text transcription, and text generation.
Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.
