By routing Claude Code through Aperture (editing a single config file), users get per-request cost breakdowns, cross-device usage tracking, and guardrails. Real examples show a simple greeting costs $0.31 due to system prompt caching, a browser game built with Claude Sonnet 4.6 ran $3.29, and a complex home automation project on Opus hit $32.76 — all invisible under a flat subscription. Aperture also enables model selection controls, MCP tool access, and data guardrails, with richer features available for API-key-based usage and teams. ## Full article daily.dev links to this article rather than hosting it.
