Free climbing uses only hands and feet on the rock for progress, with gear only to protect a fall; aid climbing makes progress by pulling on, standing in, or hanging from gear. Free climbing is the norm today; aid is for blank big walls too hard to free.

Verdict
Frequently asked questions
What's the difference between free and aid climbing?
In free climbing the rock does the work and gear only protects you; in aid climbing you pull on, stand in, or hang from gear to make progress. Aid is used where the rock is too hard or blank to climb free.
Is free climbing without a rope?
No — that's a common misconception. Free climbers almost always use a rope and protection to catch falls; 'free' means not aiding on gear, not climbing ropeless. Ropeless climbing is free soloing.
What is clean aid (C grade)?
Clean aid uses only removable protection — cams, nuts, hooks — that leaves no trace, graded on the C scale. Traditional A-grade aid may hammer pitons, which damages rock, so clean aid is preferred where possible.
