Public rankings

See the ranking before you choose

Availability, response speed, price, and report status sit on one page. Read the ranking, then open the service you want

  • Availability, response speed, and price on one page

  • Each row shows whether a report is available

  • Open that service after you choose it

View full rankings

Fair comparison

The ranking has clear rules

The same model is compared with the same published checks. Each result shows when it was measured

  • Only services for the model on the board

  • Every service uses the same published checks

  • Commercial placement does not set the order

Read the evaluation guide
01
Same model

Services are compared for the model shown at the top of the ranking

02
Same standard

The ranking uses the same published checks for every service

03
Date shown

Every result carries the date it was measured or published

04
Business stays separate

Commercial placement does not decide the order of the ranking

Evaluation reports

Every check ends with a clear report

The report says what was checked, when it was checked, and what came back. Service, time, and result stay together so you can review them

  • The report says what was checked

  • It also says when the check happened

  • Service, time, and result can be read together

Run a check when you need more detail

Pick a service, run a check you are allowed to make, and read the result in a report

  • Start with a model and service from the directory

  • Confirm you may test it before you begin

  • The finished check comes back as a report

Ranking trust

Published rules. Fair comparison

The ranking uses published results and keeps commercial display separate from order

Ranking order

Services are ordered using published evaluation results

Missing data

A missing result stays visible instead of being guessed

Commercial display

Business relationships do not directly change the ranking
