Open Source Task Management
A task list only works if capturing something is faster than the friction of opening the app, so the quiet feature that decides whether a tool survives is how little ceremony it takes to get a thought out of your head and into the system. The open source options below keep that capture loop local and fast, store your tasks in formats and databases you can read directly, and let you sync through a server you run rather than betting your daily backlog on a vendor staying in business.
