Dev Time

Setup

Dev Time benchmarks use each meta-framework’s starter-* package.

Each starter follows its framework’s CLI or documented setup, with the selected options and adjustments recorded in the methodology.

See Default Benchmark Setup for the shared benchmark environment.

Dependency Counts

Methodology: Dependency Counts.

Measuring a meta-framework’s dependencies isn’t as straightforward as you might think. You could:

• Measure just the meta-framework package itself
• Maybe a full project setup

Both approaches have flaws. Some meta-frameworks need many other packages to work. A full project setup can include more packages than necessary.

To provide a clearer picture, we run the dependency-count tests three times, starting small and expanding in scope. In this order, we:

1. Start with the meta-framework package itself, for example, @sveltejs/kit
2. We then expand this to the meta-framework and its first-party packages. Looking at @sveltejs/kit again, this means any package maintained by the meta-framework authors that’s needed to run a project, for example, the svelte package.
3. Finally, we count the dependencies for the entire starter-* project. Their CLI or documentation recommends this setup by default, so this is the default most people will start with.

Run Time

Setup

Runtime apps implement comparable benchmark routes across frameworks. See Default Benchmark Setup for the shared environment and each framework’s build tool and adapter. Test-specific differences are documented in the linked methodology sections below.

Client Side Rendered Tests (Lighthouse)

These CSR browser performance tests use Lighthouse to measure paint timings and a controlled navigation interaction.

Methodology: Client Side Rendered Tests (Lighthouse).

Some frameworks have been moved off their golden path to make client side tests fair when comparing. See the methodology link above for the full details.

Client Interaction Breakdown by Version (Lighthouse)

Total latency is split into the three consecutive phases reported by Lighthouse.

• The input delay, which starts when the user initiates an interaction with the page, and ends when the event callbacks for the interaction begin to run.
• The processing duration, which consists of the time it takes for event callbacks to run to completion.
• The presentation delay, which is the time it takes for the browser to present the next frame which contains the visual result of the interaction.

• Input delay
• Processing duration
• Presentation delay

SSR Load Test

Methodology: SSR Load Test.

Each runtime app renders the same 1,000-row, three-column table using ordinary <a> links. This compares server rendering under HTTP load without the extra work of rendering framework router link components. Requests still pass through each framework’s server routing. No browser runs and no links are clicked.

Ordinary anchors at /server-side-rendered-plain-links. Historical standard-test measurements are unavailable; new CI runs will populate this series.
