httparchive.org

One-line introduction

httparchive.org is an open data project maintained by a group of web performance experts and community volunteers, rather than a traditional commercial SaaS product. By automatically crawling and archiving loading data from millions of web pages worldwide at scale, it provides website owners, SEO practitioners, and developers with free, detailed reports on web performance and trends. People choose it because it offers real-world, large-scale, horizontally comparable performance benchmark data, helping diagnose page loading bottlenecks and track the evolution of web technologies across the industry — with core functionality available at no cost.

Business overview

httparchive.org was launched in 2010, originally initiated by web performance pioneers such as Steve Souders, to address the lack of large-scale, real-world web performance data at the time. The project is maintained by volunteers and industry sponsors, with data accumulated through regular crawls — typically once per month — of the Alexa Top 1 million websites and popular sites from the Chrome User Experience Report (CrUX).

Its core outputs include monthly HTTP Archive reports that analyze changes across a wide range of performance metrics, raw data in BigQuery for advanced users to run custom queries, and the Web Almanac, an annual industry report built on top of this data. The Web Almanac covers many dimensions, including performance, SEO, security, JavaScript usage, and more.

In the web performance field, httparchive.org is regarded as one of the most authoritative third-party data sources and is widely cited by Google engineers, major e-commerce platforms, and SaaS vendors. Its user base includes front-end development teams, SEO consultants, SaaS performance monitoring tool providers, and companies that need benchmark data to shape their performance optimization strategies.

Who it is for

httparchive.org is best suited for several types of users. First, web performance engineers and front-end developers who need to understand how mainstream websites currently perform on Core Web Vitals, so they can set realistic optimization goals for their own projects. Second, SEO specialists who need to analyze loading speed trends among competitors or leading sites in their industry in order to develop more precise ranking improvement strategies. Third, technical decision-makers such as CTOs or VPs of Engineering, who may need to present industry performance benchmarks to management or clients to justify internal performance optimization budgets. Fourth, academic researchers and industry analysts who need large-scale real-world data for reports or papers.

It is less suitable for ordinary site owners who simply want to quickly check their own website speed, because httparchive.org provides sampled snapshots rather than real-time monitoring. Its interface is also fairly technical and not especially friendly for non-technical users.

Key features and highlights

• Free and open dataset: All crawl results are publicly available in BigQuery. Anyone can query the SQL-based data for free, with no registration or subscription required.
• Monthly performance trend reports: A monthly statistical report is automatically generated, covering metrics such as JavaScript size, image formats, CSS usage, and TTFB (Time to First Byte), and can be viewed directly on the official website.
• Web Almanac: Published once per year and written by community experts, this in-depth industry report covers more than 20 chapters, including performance, SEO, security, accessibility, and more.
• Custom query capability: Users can write SQL against HTTP Archive’s public BigQuery dataset to extract specific subsets of data or perform cross-dimensional analysis, offering extremely high flexibility.
• Deep integration with Chrome UX Report: The data is based on real user browsing experience (RUM), rather than only lab testing, making it closer to what actual users experience.
• Open-source tool support: The project’s code and crawling scripts are open source, allowing the community to contribute or build similar environments independently.

Pricing analysis

The core data service of httparchive.org is completely free, which is its most obvious cost-performance advantage. Unlike GTmetrix or Pingdom, it does not impose free-tier limits or paid plan restrictions; instead, it directly provides complete datasets for download and querying.

The only potential cost is BigQuery query fees. Although the HTTP Archive dataset itself is public, running complex SQL queries on Google Cloud with very large data scans may trigger BigQuery billing. In practice, BigQuery usually includes 1TB of free query processing per month, which is more than enough for most individual users.

In addition, if you want to participate in writing the Web Almanac or sponsor the project, there may be donation or sponsorship costs, but these are not mandatory. Overall, it belongs firmly in the “free” category. For individuals and small teams, the cost is effectively zero. For companies that need large-scale, high-frequency queries, BigQuery costs are still far lower than subscriptions to commercial performance monitoring tools. There are no hidden fees.

How Chinese users can use it

In terms of network accessibility, the httparchive.org official website can generally be accessed directly from mainland China, with acceptable speed, although occasional slow loading may occur due to CDN or DNS resolution issues. Data querying depends on Google BigQuery, and access to the BigQuery API and web console from mainland China requires a VPN or other circumvention tool, because Google Cloud services are blocked. Therefore, Chinese users who want to retrieve raw data or run SQL queries usually need to prepare such access.

For payments, since the core service is free, there is no payment issue. If you need to use paid BigQuery capacity, you will need to bind an international credit card such as Visa or Mastercard; domestic UnionPay cards may not be supported.

For invoices, httparchive.org itself does not provide commercial invoices because it is a community project rather than a company. However, if you pay for queries through Google Cloud, Google Cloud can issue international invoices, typically requiring a business account.

Domestic alternatives include Tencent Cloud’s “Web Performance Monitoring” service, though its data scale is smaller; Alibaba Cloud’s performance testing tools, which focus more on lab testing than real user data; and page speed analysis features from third-party SEO tools such as Aizhan and Chinaz. However, none of them offer large-scale, free, public industry benchmark data comparable to httparchive.org.

Pros and cons

Pros:

• ✅ Completely free, with no usage restrictions and a huge data volume — millions of URLs every month.
• ✅ Data is based on real user experience (CrUX), not just lab simulations, making it more accurate.
• ✅ Open BigQuery dataset supports deep custom analysis with very high flexibility.
• ✅ Community-driven and highly transparent, with public and auditable data collection and analysis methods.
• ✅ Complete historical data supports year-over-year comparisons and tracking of technology trends.

Cons:

• ❌ Data is not real-time and is usually delayed by about one month, so it is not suitable for immediate diagnostics.
• ❌ The interface and documentation are technical, creating a relatively high learning curve for ordinary site owners or non-technical users.
• ❌ No built-in alerting or monitoring features, so it cannot proactively notify you of website performance changes.
• ❌ Relies on the Google ecosystem; Chinese users need a VPN or similar tool to access BigQuery.
• ❌ No paid support or SLA; data issues can only be reported through community channels.

Comparison with similar products

• GTmetrix: A commercial performance monitoring tool that provides detailed waterfall charts, optimization recommendations, and real-time testing. However, the free version has many restrictions, such as daily test limits and limited data retention. httparchive.org is free and has a much larger dataset, but lacks interactive debugging features.
• WebPageTest: An open-source performance testing tool that supports multi-location and multi-browser testing with detailed results, but it also lacks large-scale benchmark data. httparchive.org is better for industry trend analysis, while WebPageTest is better for deep single-page diagnostics.
• Chrome User Experience Report (CrUX): Google’s official real user experience dataset, which partially overlaps with httparchive.org’s data sources. CrUX is available through Google BigQuery and PageSpeed Insights, but its data dimensions are narrower, mainly focused on Core Web Vitals. httparchive.org adds more technical metrics on top of this, such as JavaScript size and CSS statistics, and provides richer community reports.

Final recommendation

httparchive.org is best for scenarios where you need to understand web performance benchmarks across an entire industry or a specific vertical, such as e-commerce or news portals. It is also useful if you are writing a technical report or blog post about web performance trends and need to cite authoritative data. It can serve as a “data backbone” for performance optimization teams: first check industry averages, then set internal optimization goals accordingly.

It is not a good fit if you need real-time monitoring of your own website’s performance changes, or if you want a beginner-friendly graphical tool that directly provides optimization recommendations. For Chinese users, it is recommended to start with the free monthly reports and Web Almanac on the official website, which can usually be browsed without a VPN. If you need to run in-depth BigQuery queries, prepare a suitable network access solution in advance.

Since the core functionality is completely free, there is no risk of regretting a paid purchase. Anyone interested in web performance should feel comfortable trying it directly.
