Free Alternatives to Command & Conquer
Short answer
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.
Our pick: OpenRA
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
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.
The difference: 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 clears all five: genuinely free with no monetisation, stable and complete, actively developed, good enough to recommend at full price, and open-source under GPL-3.0 so nothing can take it away.
Warzone 2100
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 clears all five: free with no monetisation, a complete commercial game with a full campaign, still actively maintained after being open-sourced, genuinely good on its own merits, and permanently available under GPL.
0 A.D.
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. clears all five. It is formally still in alpha, but it has been comfortably playable and content-complete for years, and its production values match commercial historical strategy games that charge full price.
