A maintained list of 1,432 directories, launch platforms, registries and marketplaces that accept product submissions. 1,134 of them are free or have a free tier, and 192 are quick wins — free, low effort, and worth doing first. Every row shows cost, effort and priority, and links straight to the submission page.
The table is wider than the screen — swipe it sideways for cost, effort and the preparation notes.

Behind the list
Every row here starts as a line in a sheet, gets normalised into one of 15 groups, scored for cost, effort and impact, and written up with the steps to actually submit. The floor below represents that pipeline.
