Run an agent CLI unattended, on a brief, inside a fence, under a budget, with a ledger.
SIwithin is a single-file Python CLI for macOS that runs agent CLIs like Claude Code or OpenAI Codex unattended, safely. It fences the run to approved folders, meters every API call through a loopback proxy with per-run tokens and dollar budgets, enforces a global cap and timer, and writes one ledger line per run recording cost and outcome.
Why now: It was featured on Hacker News as a Show HN, positioning itself as a practical sandbox-and-budget guardrail for running coding agents autonomously.
Who it is for: Developers who want to let AI coding agents run unattended without risking runaway costs or access to files outside the project.
