This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .
Cross-platform Delphi crash/exception reporter (Linux, macOS, Android, iOS) that emits EurekaLog .el-format reports (open in the EurekaLog Viewer): call stacks, CPU registers, modules, source line numbers. RTL-only core, no FMX dependency, no EurekaLog license required.
Mirror of: Spring4D. This is an unofficial mirror of the Spring4D Bitbucket repository and is for convenience use only. It is synchronized at irregular intervals. For submitting patches or bug reports, go to https://bitbucket.org/sglienke/spring4d
My fork of GraphicEx based on the latest version in the VirtualTreeView repo in 2012. I am aware of the new repo on GitHub but this was already forked before that existed. This fork has lots of bugfixes by me and others. Delphi 32 bits and Fpc/Lazarus Win32/Win64 compatible. Both contributions and bug reports are welcome.
Turbo Pascal + x86 asm DOS demo from 1998 (bug-fixed in 2026), featuring custom font rendering, palette effects, plasma, a VW Golf image effect, and rotating 3D point graphics.
Key Objects Library and Mirror Classes Kit (KOL&MCK) and attendant components for Delphi from Delphi2 to DelphiXE is an alternative to VCL to create small applications for Windows platform, freeware with sources. Project was started in 2000, dozens of programmers have created a lot components, helped in fixing a lot of bugs, write pieces of code in the KOL itself.

. Delphi madExcept was built to help you locate bugs in your software. Whenever there's a crash/exception in your program, madExcept will automatically catch it, analyze it, collect lots of useful information, and give the end user the possibility to send you a full bug report. madExcept is also able to find memory leaks, resource leaks and buffer overruns for you.
A getopt unit for DOS Borland compilers and Free Pascal based on the GNU textutils 1.12 getopt implementation and Håkon Løvdal's Turbo Pascal port. Contains a friendlier interface and several bug fixes.
. Delphi unit that fixes VCL and RTL bugs at runtime by patching the original functions. If you want all IDE Fix Pack fixes in your application this unit is what you are looking for. Adding the unit to your project Delphi and C++Builder automatically installs the patches that are available for your Delphi/C++Builder version.

This is a RAD Studio wizard / expert / plug-in which allow you to right click on an identifier in the code editor and add a breakpoint which contains a CodeSite.Send() evaluation expression so you can debug code with CodeSite without having to alter the underlying code (useful for debugging RTL and the VCL).
Debugging Tools for RAD Studio - a small RAD Studio plug-in that provides keyboard access to the breakpoint editor and incorporates the functionality of [Debug with CodeSite](https://github.com/DGH2112/Debug-with-CodeSite).
A family of FLEA-inspired CSPRNGs and Stream Ciphers, BEDBUG is a small, fast, cryptographically secure pseudo-random number generator. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.
DMVCFramework (for short) is a popular and powerful framework for Web API and Web Applications in Delphi. Supports RESTful and JSON-RPC WEB APIs development.
Alcinoe empowers developers to build fast, modern apps without the usual complexity or performance bottlenecks. It keeps the focus on innovation—not tool constraints—delivering top performance, deep customization, and great cross-platform UX while staying independent of GAFA ecosystems.
Four engines to render SVG (Delphi Image32, SVGMagic, Skia4Delphi, Direct2D wrapper) and four components to simplify use of SVG images (resize, fixedcolor, grayscale...) for VCL and FMX platforms.
FastMM is a fast replacement memory manager for Embarcadero Delphi applications that scales well across multiple threads and CPU cores, is not prone to memory fragmentation, and supports shared memory without the use of external .DLL files.
