OpenRA is the best free alternative to Command & Conquer: it is an actively maintained open-source rebuild of Tiberian Dawn, Red Alert and Dune 2000, it is genuinely free with no monetisation, and it has a live multiplayer ladder.
The Command & Conquer series is largely abandoned as a live product, and the Remastered Collection still costs money. There is a free option that is not a knock-off but a faithful, actively developed rebuild of the original games — with modern resolutions, proper multiplayer and an active ladder.

OpenRA rebuilds Tiberian Dawn, Red Alert and Dune 2000 on a modern open-source engine. It is the closest thing to an official continuation of the series.
How it differs from Command & Conquer: Unit control, pathfinding and build queues are modernised rather than replicated exactly, so long-time players should expect rebalanced skirmishes rather than a pixel-perfect recreation.

OpenRA scratches a very specific itch: remembering how much fun old Command & Conquer was, without having to treat a 1990s PC like a museum exhibit. We picked it because it doesn't merely preserve those games, it understands what made them fun and gives them room to breathe. The result feels familiar within seconds, but the modern controls, multiplayer, balance changes, and community creativity make it surprisingly easy to get hooked again.
Warzone 2100 was a commercial 1999 RTS that was open-sourced, and it has been in continuous development ever since. Its research tree and unit designer go deeper than anything in C&C.
The difference: Slower and more systems-heavy than C&C. You design your own units from researched components rather than picking from a fixed roster.
Warzone 2100 has a surprisingly good answer to the question: what if an RTS actually let you build the army you wanted? Its technology tree and vehicle designer give it a level of experimentation that makes every campaign feel a little different. It's old-school strategy with an unusually satisfying amount of tinkering. You could say it lets you be the Supreme Commander
0 A.D. delivers the same base-build-then-attack rhythm at a much higher production standard, in a historical Bronze Age setting.
The difference: Historical rather than modern/sci-fi, and considerably slower-paced. Closer to Age of Empires than to Red Alert.
0 A.D. is an unusually ambitious free RTS that can stand alongside commercial strategy games on its own merits. Huge armies, distinct civilizations, meaningful economies, multiplayer, and extensive modding make it an easy PlayBound recommendation.
