That's a really good question. I generally end up building these tools for personal use or to see if some design space is worth exploring, and so don't bother cleaning up the code/making it easy for other people to run. In addition, people now have the expectation that people releasing open source code owe them some manner of improvements/support/maintenance, something I'm not interested in doing. I like David Beazley's recent tweet about releasing his code asis - https://twitter.com/dabeaz/status/1069236767029633024 https://twitter.com/dabeaz/status/1069236767029633024 I've got a number of tools like this - a basic SQL GUI for doing analytics (https://news.ycombinator.com/item?id=14050833 https://news.ycombinator.com/item?id=14050833), a Tableau like clone with interactive graphics for visual analytics (https://pbs.twimg.com/media/Cyji3jRWIAA2LRY.jpg:large https://pbs.twimg.com/media/Cyji3jRWIAA2LRY.jpg:large) - your comment is making me reconsider that people might find them useful without any expectation of support/warrantee of fitness.
