Free productivity tools

This page lists productivity tools that cost nothing to start with. The three here take different routes. Strata Files is a native Mac file manager that is open source under the MIT license, so it is free to download and use.

Lemongraph and Novastart use freemium plans. Lemongraph tracks work promises and offers 5 integrations and 15 chore runs a month on its free tier. Novastart is an infinite canvas workspace, and its free plan is capped at 1 folder, 2 canvases and 4 windows.
