Frequently Asked Questions

EcoPulse is a free web tool that analyzes websites to measure their environmental impact. We calculate carbon emissions, energy consumption, and water usage based on page size, resources loaded, and other factors. Our goal is to help developers build more sustainable websites.

Yes! EcoPulse is completely free to use. You can analyze unlimited websites and access all features without any cost. We believe environmental awareness should be accessible to everyone.

Our calculations are based on industry-standard methodologies and research data. We use average carbon intensity values (442g CO2/kWh), energy consumption estimates (0.81 kWh/GB), and water usage factors. While these are estimates, they provide a reliable baseline for comparison and optimization.

You can analyze most publicly accessible websites. However, some sites may block automated access or have security measures that prevent analysis. Private or password-protected pages cannot be analyzed.

We use Puppeteer (a headless Chrome browser) to load your website exactly as a real user would. We intercept all network requests, measure resource sizes, track load times, and analyze the page structure. This data is then processed through our environmental impact algorithms.

Several factors influence the Eco Score: total page size, amount of JavaScript, third-party resources, image optimization, caching headers, and overall resource efficiency. Smaller, optimized pages with minimal JavaScript score higher.

The carbon footprint (measured in grams of CO2) represents the estimated greenhouse gas emissions produced each time someone loads your webpage. This includes the energy used by data centers, networks, and the user's device.

Energy consumption is calculated based on the amount of data transferred. We use the formula: Energy (kWh) = Data (GB) × 0.81 kWh/GB. This accounts for data center operations, network infrastructure, and end-user device energy.

Data centers require significant water for cooling systems. We estimate water usage at 1.5 liters per kWh of energy consumed. This helps provide a complete picture of environmental impact beyond just carbon emissions.

Focus on these key areas: 1) Compress and optimize images (use WebP/AVIF), 2) Minimize JavaScript and remove unused code, 3) Enable caching and compression, 4) Reduce third-party scripts, 5) Use lazy loading for images and videos, 6) Choose green hosting providers.

An 'A' rating (80-100) indicates excellent environmental efficiency. 'B' (60-79) is good but has room for improvement. 'C' (40-59) is average. 'D' (20-39) needs significant optimization. 'F' (0-19) indicates serious issues that should be addressed.

Images often account for 50-80% of a webpage's total size. Optimizing images through compression, using modern formats (WebP, AVIF), and implementing lazy loading can dramatically reduce your environmental impact.

Not necessarily, but you should audit them. Each third-party script adds to page weight and energy consumption. Keep essential ones (like analytics) but remove unused plugins, trackers, and widgets. Consider self-hosting critical resources.

We store the analyzed URL, page metrics, and analysis results for aggregate statistics. We also track anonymous visitor data (hashed IP + user agent) to count unique visitors. We do not store personal information unless you provide feedback or subscribe to our newsletter.

No, website owners cannot identify that you specifically analyzed their site. Our analysis appears as a regular page visit from our servers. We don't notify website owners or share analysis data with them.

Absolutely not. We do not sell, trade, or share personal data with third parties for commercial purposes. We only use data to improve our services and generate aggregate statistics.

EcoPulse was created by Mamun Rahaman, a developer passionate about sustainable technology. The project aims to raise awareness about the environmental impact of the internet and provide tools for greener web development.

Yes! EcoPulse is open source and available on GitHub. You can view the code, contribute improvements, or fork the project for your own use. We believe in transparency and community collaboration.

There are several ways to contribute: 1) Submit feedback and suggestions, 2) Report bugs or issues, 3) Contribute code on GitHub, 4) Share EcoPulse with others, 5) Write about sustainable web development.
