AVRPascal
AVRPascal is a Pascal code editor for AVR microcontrollers (ATtiny and ATmega families). It uses the FreePascal compiler to compile source code, and AVRdude to transfer the code to the microcontroller's memory using the USBasp programmer or Arduino boards.
Bhyvemgr
Bhyvemgr is a bhyve management GUI written in Freepascal/Lazarus on FreeBSD. It needs a bunch of tools mostly installed on base system and some installed from ports/packages. Currently it supports amd64 and aarch64. The main goal is to be a desktop user application to easily and quickly setup and run virtual machines on the FreeBSD host.
Convert POs
Lazarus project, whose fusion an original po file and the translated po file. You can save your po language file after.
Dexed
dexed, formerly known as Coedit, is a small, open-source, cross-platform IDE for the D language. It features:
- full featured project format and advanced project editor.
- compile and run directly from the UI.
- instant run (without saving, script-like).
- synchronized edition in a block.
- D2 syntax highlighter, folding, identifier markup.
- module symbol list.
- static libraries manager.
- search and replace.
- user-defined tools powered by a string interpolation system.
- D Completion Daemon integration for completion proposal and source code hints.
- mini file browser.
Diacrit
Diacrit is a utility to help with access to Unicode characters, choose the language you want. click the character button and paste into your application. Diacrit was first written in Turbo Pascal for Windows back in 1996, migrated to Delphi, and now upgraded to FPC/Lazarus.
Double Commander
Double Commander is a cross platform open source file manager with two panels side by side. It is inspired by Total Commander and features some new ideas.
ExifSpy
ExifSpy is a tool for peeking into the binary structure of EXIF metadata of picture files:
- Navigate through the jpeg file structure
- Navigate through the EXIF tag directories
- Display and analyze binary metadata records (EXIF, IPTC, XMP)
- Display and analyze jpeg ICC color profiles
- Embedded hex viewer combining the bytes beginning at the cursor position to conventional data types in both big endian and little endian byte order.
ExPress
ExPress is a GUI wrapper for UPX (Ultimate Packer for eXecutables).
Hex
Hex is an open source hex editor with some features that are useful for analyzing binary files ("reverse-engineering"):
- Numeric viewer: displays the byte selected by the cursor and the following bytes of standard Pascal numeric data types (byte, shortint, word, ..., singe, double, real48) as a usual number.
- Record viewer: allows to construct "records" from the basic Pascal types. The record elements are displayed in "human-readable" form. Commands are available to scroll through the file record by record.
- Object viewer: displays embedded images.
Hexy
Hexy is a cross-platform tool for embedded C developers. It automatically converts binary files into C header files containing hexadecimal arrays for integration into embedded projects.
InstallAware (Multi Platform) 2025
InstallAware 2025 is a cross-platform tool for application developers looking to self-publish (and update) their software on Windows, macOS, and Linux. It builds native code, fully self-contained setup programs that run without requiring any libraries or dependencies. Apple Intel, Apple Silicon, Linux GTK2, Linux Qt5, Linux aarch64, Linux x86_64, and Windows are all supported from a single source - driven by a free-flowing setup script that dynamically adapts to the underlying operating system. The setup wizard dialogs are fully editable as well (using an editor just like Lazarus' own), and they look and feel the same on each supported platform.
- Easily jumpstart a setup project using the Quick Start Wizard or any of the extensive template/sample projects. Remember, one source deploys everywhere!
- Import any existing setup you built (up to 21 years ago) in InstallAware for Windows Installer, and recompile it for macOS and/or Linux - retaining all of your custom script logic and dialogs - in literally a single click.
- Just like its closed source sibling, InstallAware (Multi Platform) 2025 supports Partial Web Deployment, fully customizable Web Updates, command line builds, advanced Setup Capture (snapshot based - works by monitoring the changes an application/installer makes to the system), and localizations. If you've used InstallAware before, you'll find everything exactly where you expect them to be. Everything works exactly the same way you're used to from before.
- Each of these tools are implemented entirely as native code on each platform, just like the setup engine itself; with everything coded 100% in Lazarus, and sources fully published.
- InstallAware is so advanced, in the rare instances where Linux widget support is missing, it renders customized dialogs in pure character mode - ensuring 100% successful payload delivery on even the most locked down of environments. The character mode setup engine is available for Windows and macOS, too.
LPTK
Light Pascal ToolKit is a native, Object Pascal language GUI framework.
MouseAndKeyInput
MouseAndKeyInput is a tool for cross-platform manipulation with mouse and key input. You can move mouse cursor to specified location, send clicks and do key presses. It is suitable for GUI testing or program control demonstration.
P65Pas
P65Pas is a Pascal compiler and IDE, which generates binary and ASM code for the 6502 CPU.
PasDoc
PasDoc (webpage) is an open-source documentation generator for ObjectPascal source code. It reads documentation from comments in your source code (an option to read it from an external file is also available), and generates nice docs in HTML, LaTeX or other formats. We have a console program, and a cross-platform GUI version using Lazarus.
PicPas
PicPas is a Open Source Crossplatform Pascal compiler, for midrange PIC microcontrollers (most of the 16F series). No additional libraries or software required to compile. PicPas generates the *.hex file directly. PicPas works with a simplified version of the Pascal language, that has been adapted to work with limited resources small devices. Currently, it only supports basic types. It includes a very complete IDE to facilitate the development. The compiler includes optimization options so the code obtained is fairly compact, as that could generate any commercial compiler.
QFront
QFront is a platform independent frontend for the CPU Emulator QEmu
SVN::Observator
SVN::Observator is a simple tool to monitor svn repositories for new commits. It uses the original svn client to connect to the repositories. Binaries for Linux and Windows are available.
Win32 API Manager
The API Manager is a very old program giving a GUI for Win32 API functions. It can do everything there is an API function for, e.g. list all processes, change their priority or kill them; list all windows and change their attributes (e.g. change a password, edit to a normal, readable edit) ... It was originally written with D4 for Win98, but I ported it to Lazarus and added support for NT-platform functions. So, it should still work nowadays.
zDevStudio
zDevStudio is an open source cross-platform IDE based on Pasmo compiler designed to help coders and retrocoders to develop software for Zilog Z80 8-bit CPU.
TOPAZZIO - Lazarus Project Creator
Topazzio Create a complete Lazarus project from your database tables, splash screen, login screen, main screen with menu for forms, reports, etc. You will only have to adjust the components on the screen.
Topazzio supports Brazilian Portuguese, English and Spanish. The generated project will also be in the selected language.
