I've been having a lot of fun with this developing tiny webapps using Fullmoon[1]. I love Lua, but I frequently bounce between a Windows PC and a Linux PC. Having redbean + Fullmoon has made it a breeze switching back and forth without having to deal with system Lua installs. SQLite and the thorough amount of built-ins[2] is also a dream. Lua also has a lovingly awesome hobbyist community, so having another outlet for me to leverage that ecosystem is great.
