Open Source software is known since the mid 1980s. During this time, computer enthusiasts have reprogrammed Unix software in C. Many new programs and entire operating systems are available as open source and there are dedicated conferences of the FOSS community.
Open Source has many advantages over commercial software because Open Source programs are available as source code and they are distributed free of charge. The shared similarity to commercial software is, that human programmers are needed to create the code. Especially for larger projects like Office, or photo editing software this bottleneck is a serious problem.
Since a while there is a revolution available for the software industry triggered by large language models specialized for writing software. One of the newly created programs is Wordcraft which is Word clone and it is running on Windows, Mac and Linux. The original Word program consists of a large codebase and is only available for Windows, while the Wordcraft clone was written in Rust and runs even in the webbrowser.
It seems, that with the correct prompt and a recent AI tool its possible to clone software. A human programmer defines the goal, while the AI writes the code. This allows to bypass the slow development of human written software which is around 10 lines of code per day and programmer.[1]
Computers until the year 2022 were able to copy the software itself, a zip file which holds a software can be send from one computer to another in a minute. This allows to distribute open source software very fast. The bottleneck was to create new software. If someone likes to start a new open source project, he need a months upto years until the software was written and tested. The duration can be reduced by increasing the amount of programmers but its hard to coordinate these teams.
With the advent of vibe coding the former bottleneck can be solved partly. Similar to a neural networks which can generate photos from scratch, a large language model is useful to generate computer code from scratch. There is no need for a software team anymore, but software can be created by a single text prompt which gets executed in minutes.
Its pretty easy to predict the outcome of this technology. The amount of vibe coded software at github will grow exponentially. Every programmer who has in idea can program an entire software with the help of Artificial intelligence and publish the result online. Such kind of revolution will question existing commercial software and open source software both. The new boundary is between human written code and AI generated code.
Lets take a look into the project. The screenshot was taken in Linuxmint and shows the help screen. It gives the information who created the software, Claude Opus, and how many lines of code were needed in Rust,
In a short text, a word document was created and converted into a pdf document. Also the word document was opened with Libreoffice. All the operations are working. It seems, that the wordcraft project is a very powerful clone of the original software.
Its interesting to take a look into the github page of wordcraft because it documents the rapid changelog. From the Linux kernel is known, that a huge amount of commits is added to the project, so a new kernel gets released every 2 months. In case of the wordcraft project the frequency is much higher. The version shown in th former screenshot is 0.7.0 from Oct 14, 2026. The current latest version is 0.13.2 with lots of improvements.
The duration between both releases was only 2 weeks. No human programming team is able to improve the software in such short amount of time. The only explanation why the software is changing so fast, is:
a) the software version 1.0 was written already and the shown version at github is outdated
or b) the version 1.0 doesn't exist yet and an artificial intelligence is improving the software on a daily basis
Its not clear how the software was made. What is known for sure is that there is no other Wordprocessing available written in Rust with such a high amount of features. Calling the project a Word clone is an understatement.
