There are quite a few Delphi open source projects on GitHub that can really save you some time. I searched for Delphi on GitHub and then sorted by the Most Starred projects and came up with this Top 10 list. There is some really good stuff here including Awesome Delphi (which is another top list), Delphi IDE color theming projects, an MVC web framework, a REST API client, Open Source Computer Vision Library headers for Delphi, a really powerful custom TreeView component, a unit testing framework, a component for embedding Chrome in your app, and finally the fantastic OmniThreadLibrary.

ZylCPUUsage is a visual Delphi & C++Builder component that diplays the usage level of the processor(s) in a chart. This version is fully functional in Delphi and C++Builder IDE, but it displays a nag dialog (the licensed version will, of course, not have a nag dialog and will not be limited to the IDE). The package includes demo programs for Delphi and C++Builder and a help file with the description of the component.

ZylBurner is a CD, DVD and Bluray burner Delphi & C++Builder component. It is based on NeroCmd utility, so it needs Nero Burning ROM to be installed. This component is very easy to use, it's ideal for developers for quick CD and DVD writing purposes from Delphi or C++Builder. The component works in two modes: synchronous mode and asynchronous mode. In synchronous mode the operational functions (Burn, Erase, BurnImage, Eject) always wait for the end of the current operation and return a value which indicates if the operation was successful or not. In synchronous mode the return value of the operational functions is always 0, and the functions don't wait for the end of the current operation. You can use it to burn data CDs, DVDs and Blurays, audio CDs, video CDs, supervideo CDs and video DVDs.

ZylBattery is a visual Delphi/C++Builder component that diplays the charging level of the battery in a chart. You can specify different colors for different charging levels and you can indicate it also in text format in percents.

DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).

ZylAppCommunicator is a Delphi & C++Builder component which lets you to communicate between one or more applications which are running on the same computer. Use ZylAppCommunicator if you want to easily communicate between your applications.

You have reached the home of Smart Mobile Studio, a very exciting project that allows you to write ordinary Pascal in the flavour made famous by Delphi and Free Pascal, but generate feature rich, cutting edge HTML5 web applications ready for the mobile market.The fundamental difference between Smart and other rapid application development (RAD) systems is that Smart does not rely on a server. You author the project just like you would do in Delphi or Visual Studio and it’s instantly converted into high-speed jаvascript. Our philosophy is that the browser is the new operative system. The code generated by our compiler is ready to run on your iPhone or any HTML5 web-kit empowered device.

ZylGPSReceiver is a Delphi & C++Builder component collection that communicates with a GPS receiver (Global Positioning System). It returns latitude, longitude, altitude, speed, course, heading and many other useful parameters of the current position and the parameters of the satellites in view. The component is extended to calculate distances and make conversions between different measurement units. This component works with any NMEA 0183 compilant GPS receiver connected to one of the serial ports. NMEA 0183 (or NMEA for short) is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, Anemometer (winds speed and direction), gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the US-based National Marine Electronics Association.

DITidy is an embedded HTML parser and pretty printer for Delphi (Embarcadero / CodeGear / Borland). It is build on the libtidy library but requires no DLLs or other external files whatsoever. All code is compiled right into the application's executable.
