Sitespeed.io is a set of Open Source tools that makes it easy to monitor and measure the performance of your web site.
Measuring performance shouldn’t be hard: you should be able to have full control of your metrics, own your own data and you should be able to do it without paying top dollars.
That’s why we created sitespeed.io.
Use our Docker container to get an environment with Firefox, Chrome, XVFB and sitespeed.io up and running as fast as you can download them. They work extremely well together with Graphite/InfluxDB and Grafana that you can use to monitor your web site.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:9.6.0 https://www.sitespeed.io/
If you want to test a user scenario/journey read how to run test scripts.
Install sitespeed.io globally:
npm install -g sitespeed.io
And then run:
Follow our connectivity guide to emulate real users connectivity.
Do you want to compare your performance against other web sites? Use the new performance leaderboard! Read the blog post to find out more.
If you want to measure the performance and are only interested in timing metrics, you should focus on using Browsertime. If you want it all: use sitespeed.io. It is the main tool that uses all sitespeed.io tools and add supports for testing multiple pages as well as adds the ability to report the metrics to a TSDB (Graphite and InfluxDB). Use it to monitor the performance of your web site.
You can compare performance timings, how the page is built, how much CPU the page is using and many many more things. And the leaderboard is also configurable through Grafana, so you can add the metrics that are important to you!
Using sitespeed.io together with Grafana and Graphite enables you to monitor the performance of your web site. We have a prepared docker-compose file for your setup and some ready made generic Grafana dashboards that will make it easy for you to get it up and running. You can get it up and running in almost 5 minutes!
We have a version of the dashboard at dashboard.sitespeed.io where you can have look and try it out.
We’ve been using the dashboards for years and years and it works really good. Read the documentation on how to set it up and get going.
We take your privacy really serious: Our documentation site, our dashboard and our compare tool do not use any tracking software at all (no Google Analytics or any other tracking software). None of the sitespeed.io tools call home.
But beware: Chrome and Firefox can call home (we know for fact that they both do). We would love PRs and tips how to make sure browsers don’t call home when you run your tests.

Sitespeed.io is Open Source and totally free. But what does it cost to have an instance of sitespeed.io up and running?
If you don’t run on your own servers, we recommend running on Digital Ocean optimized droplets 2 vCPUs or on AWS c5.large, storing the data at S3. On one instance you can run something like 80000+ runs per month for a total cost of $695 per year.
Sitespeed.io is built upon Open Source tools, we have a special place in our hearts for those projects (see the full list):
