Cline

Cline is actually making moves — this AI coding agent went from a 47% success rate to 57% on Terminal Bench's 89 real-world coding tasks, which is a 10-point jump that actually matters in a space where most coding assistants peak around the mid-40s. The methodology, iterative hill climbing, is the kind of boring-sounding thing that works, and the results speak for themselves — if you're shipping code and not looking at this, you're flying manual.
