This is a free, personal, non-commercial tool provided as-is, with no warranty and no guarantees. Use it at your own risk.
Load/Watt is a personal project, not a commercial product or company. It's a single web page that profiles page-load performance and estimated power draw, entirely in your browser.
You're welcome to use this tool for free, for personal or commercial purposes, on any HTML files or public repos you have the right to profile. No account or payment is required.
You're responsible for the files you drop in, the repos you point this tool at, and any custom JavaScript you write in the "custom process" field — which runs directly in your own browser tab. Don't profile content you don't have the right to use, and don't paste in code you don't trust, since it executes with the same access as the rest of the page in your tab.
The power draw and lag indices, gauges, and recommendations are directional estimates built from browser-exposed timing APIs. Browsers don't expose true hardware wattage — treat every number here as a relative signal for spotting patterns, not a calibrated measurement, and don't rely on it for anything safety-critical.
This tool is provided "as is," with no warranties of any kind, express or implied. There's no guarantee it will be available, accurate, error-free, or fit for any particular purpose. It may change, break, or go offline at any time, since it's maintained in spare time as a hobby project.
To the fullest extent permitted by law, I'm not liable for any damages or losses arising from your use of this tool, including anything that results from custom code you choose to run in it.
The GitHub repo loader sends requests from your browser to the GitHub API and the jsDelivr CDN, each subject to their own terms. Google Fonts is used for page typography.
Source code for this project may be publicly viewable on GitHub. Check the repository for any applicable license terms before reusing the code.
These terms may be updated from time to time. Continued use of the tool after changes are posted means you accept the updated terms.
