Description and use

**Summary**
PUMAS (Power Usage Monitor for Apple Silicon) is a Rust‑based tool that measures and visualises energy consumption on M‑series Macs. With over 200 ★ on GitHub and a recent update (13 May 2026), it can be handy for developers who need quick feedback on power‑draw during prototyping or internal testing, provided the README and activity align with their workflow.

**Value**

• Gives developers concrete, per‑process power‑usage data on Apple Silicon, helping to spot inefficiencies early and to benchmark optimisations.
• Because it is open‑source and written in Rust, it can be compiled and extended without licensing concerns, and it integrates well with existing Rust‑centric toolchains.

**Practical adoption path**

1. **Review the README** to understand the required CLI arguments and the supported hardware (Apple Silicon only).
2. **Clone the repo** and build the binary (cargo build --release).
3. **Run a pilot** on a non‑critical machine, collecting data for a representative workload.

4 – 5. **Validate the output** (CSV/JSON) against your own power‑measurement expectations; if the format fits, wrap the call in your CI/CD or internal scripts.
If the integration points (e.g., data export, exit codes) are insufficient, consider contributing a small patch or wrapper.

**Production readiness**

• **Maturity:** Medium. The project is actively maintained (last commit a day ago) and has a modest community (216 ★, 11 forks), but documentation is sparse and integration hooks are not explicit.
• **Risk:** The integration path is not well‑documented; you’ll need to manually verify that the tool can be automated and that its dependencies (Rust toolchain, libproc, etc.) are acceptable for your environment.
• **Recommendation:** Suitable for prototypes, internal dashboards, or performance‑testing pipelines after a short validation phase. For mission‑critical production use, perform a dependency audit, add automated health‑checks, and consider contributing missing integration features.

Use in a workflow

graelo/pumas may be useful when its README and activity match a concrete workflow.

Limitations and review notes

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.
