Software Forge Performance Index

This webpage collects performance information about various hosted software development services. The reports are updated weekly, most recently on April 16nd, 2020 at 15:55 UTC, and were generated with Lighthouse 5.6.0. Patches welcome!

Disclaimer: This website is maintained by SourceHut.

Expand for details on methodology

We ran Lighthouse 5.6.0 on Alpine Linux x86_64, with the following command line: 

lighthouse <url> \
    --only-categories=performance,accessibility \
    --emulated-form-factor=none

The emulated mobile form factor was disabled because it's rare that a developer is coding on a mobile device — and some forges have separate mobile sites, so a separate test suite would be warranted.

We left the throttling settings at the Lighthouse default, because it's less rare that a developer is tethered to their phone or working from a community with less privileged internet access. The simulated latency also helps to reduce the variable impact of real-world latency. Additionally, simulating a low-bandwidth connection helps to draw out the differences between services more clearly.

The source code is available if you wish to run these benchmarks on your own system; it takes about an hour.
