Stars Without Number vs Starfinder: Which Sci-Fi RPG Fits Your Table?
Short answer
Stars Without Number vs Starfinder comes down to sandbox versus adventure path. Stars Without Number hands the GM tools to generate a sector and let the players loose in it. Starfinder is a heavier tactical game with published campaigns and far more character-build depth.
Stars Without Number and Starfinder are both science fiction tabletop roleplaying games, and they are built for almost opposite tables. Stars Without Number is a GM toolkit: it generates a sector, populates it with worlds and factions, and expects the players to pick a direction. Starfinder is a tactical d20 game with deep character options and published adventure paths to run.

What Stars Without Number is good at
Generation. The sector, the worlds, the factions, and the adventure seeds all come out of tables, and the faction turn quietly moves the setting while the players are elsewhere. Combat is quick and dangerous, so fights are decisions rather than set pieces. Character creation takes minutes, which matters when a character can die.
What Starfinder is good at
Depth of build and depth of support. If your players enjoy assembling a character across feats and gear, there is far more of that here. If you would rather run a written campaign than invent one, the adventure paths are the strongest argument for it.
How to pick
Ask who is doing the inventing. If you want to build a setting and let the table push on it, Stars Without Number gives you the machinery. If you want to open a book and run tonight's session, Starfinder gives you the book.
Running either one online
Both work in a generic virtual tabletop, and both give you homework there. A sector in a generic tool is an image you annotate, and a faction turn is a note you remember to update. Our Stars Without Number tabletop treats those as real objects: an 8 by 10 hex grid, worlds with filterable tags, and factions that track assets and goals. Free for one game, with unlimited players.
