A workshop under the hill
Good tools, freely given.
Everything here runs locally in your browser. No servers. No accounts. No data collected, sold, or quietly observed.
Download it, open it, it works.
These tools were built out of frustration with subscriptions and the quiet indignity of paying monthly for something that should just exist. If one of these tools saves you an afternoon, that's enough.
Take what's useful. Leave what isn't. And if something helps, the tip jar is always open.
Everything here is free and always will be. But good tools take time to make and keep up. If something from Underhill saved you an hour — or just made your day a little easier — buying a coffee keeps the workshop warm.
