PSI Swarm
PSI Swarm measures website performance as repeated distributions instead of a single flattering Lighthouse run.
Maker note
Why I made this.
I wanted repeatable evidence of how my products perform under real Lighthouse conditions, not a single flattering test.
Product contract
What this product promises.
PSI Swarm measures website performance as repeated distributions instead of a single flattering Lighthouse run.
- For
- The Fleet operator and developers who need trustworthy performance evidence across public products.
- Outcome
- See typical performance, variability, and regressions under repeated real measurement conditions.
- How
- An operational CLI runs and aggregates multiple PageSpeed and Lighthouse observations for Site Health.
- Proof
- The completed measurement tool already feeds repeated performance evidence into the portfolio dashboard.
- Next action
- Run it for a concrete performance investigation or consume its evidence in Site Health; keep the tool operationally narrow.
