The human-readable text of a computer program written in a programming language before it is translated into machine language (compiled) or executed (interpreted).
example
Der Entwickler hat den Quellcode der Software veröffentlicht, damit andere ihn verbessern können.
The developer published the source code of the software so that others could improve it.
Usage tips
Compound word
The word is made up of 'die Quelle' (source) and 'der Code' (code). So it literally means 'the code that comes from the source' and is the human-readable form of a program.
EXAMPLE
Open-Source-Projekte machen ihren Quellcode öffentlich zugänglich.
Open-source projects make their source code publicly accessible.
Register: technical language
'Quellcode' (source code) is a technical term from computer science and software development. It is rarely used in everyday language.
EXAMPLE
Um den Fehler zu finden, musste der Programmierer den gesamten Quellcode durchsehen.
To find the error, the programmer had to look through the entire source code.
Typical collocations
Common verbs used with 'Quellcode' (source code) are 'den Quellcode schreiben' (to write the source code), 'lesen' (to read), 'veröffentlichen' (to publish), or 'analysieren' (to analyze).
EXAMPLE
Viele Entwickler lesen den Quellcode von bekannter Software, um daraus zu lernen.
Many developers read the source code of well-known software in order to learn from it.

Quellcode vs Quelle
source
'die Quelle' and 'der Quellcode' can both have to do with the text of a program in computer science. 'der Quellcode' is the more precise and standard word for human-readable program text. In this field, 'die Quelle' can be short for source text or source code, but it is less clear because 'Quelle' also has many other meanings. Learners may confuse the words because they sound similar and both begin with 'Quell-'. When it is clearly about programming, 'Quellcode' is usually more precise.
Quellcode
Die Entwicklerin prüft den Quellcode, bevor sie das Programm startet.
The developer checks the source code before starting the program.
Quelle
Im Projektordner liegt die Quelle der kleinen App.
The source code for the small app is in the project folder.
