Shipped: Cheap-agent
Cheap Agent runs inside Claude Code and Codex. Opus writes a short task, DeepSeek writes the code in its own copy of your repo, and nothing lands until a test passes. You never open a second tool.
63% fewer Opus tokens on the same feature, 59% fewer on SWE-bench bugs, same solve rate. Built for anyone whose $20 plan runs out by Wednesday.
Free, MIT, one command: npx cheap-agent
