It helps developers understand memory usage patterns and optimize their applications to fit within flash constraints\u2014a critical concern in resource-constrained embedded systems. The tool is part of the ESP-IDF SDK but is also available as a standalone PyPI package.\n\nAs of version 2.0.0, the package uses a new-generation implementation by default, with improved performance and additional features. It depends on pyyaml for configuration, rich for terminal output formatting, rich_click for CLI handling, and esp-pylib for Espressif-specific utilities. The package supports Python 3.7 through 3.14 and runs on macOS, Windows, and POSIX systems.","worth_installing":"Yes, if you develop with ESP-IDF. The tool is actively maintained, has no known vulnerabilities, and low install friction. It directly addresses a core IoT development problem\u2014firmware size optimization. The recent 2.3.1 release and active maintenance signal reliability. Install it if you need to analyze or optimize Espressif device firmware; skip it if you don't work with ESP-IDF."},"id":"esp-idf-size","links":{"html":"https://skillfed.io/packages/esp-idf-size","md":"https://skillfed.io/packages/esp-idf-size.md","pypi":"https://pypi.org/project/esp-idf-size/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-13","license_spdx":null,"license_treatment":"permissive","name":"esp-idf-size","python_support":"supports_current","summary":"Firmware size analysis for ESP-IDF"},"popularity":{"monthly_downloads":1301295,"position":4084,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.3.1"}
