Dev exposes Arca: paid Claude-trace marketplace is "a machine for taking your code for free"
jimmykoppel · x · 2026-11-13
Jimmy Koppel calls Arca (by Brevis), an app that pays users for anonymized Claude coding sessions, "the biggest scam of the month": upon confirming a submission you grant Arca an irrevocable, perpetual, sublicensable right to use, license and sell your artifacts — and the fine print wants your whole repo, not just sessions. He notes a real market exists for Claude traces (RLHF and distillation), but Arca is structured to take your code without paying you.
