0xSero reviews a range of coding-agent harnesses and explains how his preferences change with the task. His rankings reflect personal experience, not a controlled benchmark or a guarantee of safety, model quality or current subscription value.
0xSero highlights Pi's layered architecture, OpenCode's separate client and server, and configurations that assign different models to execution, review or advice. He argues that compact initial context and reusable connections matter when running local models.
0xSero demonstrates experiments with browser games and longer-running local tasks, including research and quantization work. These examples illustrate his workflow rather than a reproducible speed comparison. He concludes that connecting inference to existing harnesses is more useful to him than maintaining another complete harness.
