Speed Test API & Embeddable Widget
Bring real connection diagnostics to your product. REST API and embeddable widgets on self-hosted api.speedtest.doctor — same engine as our speed test, with structured JSON and shareable reports.
Measurement API
Run speed and full diagnostic panels programmatically and pull back clean, structured JSON — throughput, latency, jitter, loss and bufferbloat.
Embeddable widget
Drop a fast, white-label tester onto your own site or customer portal with two lines of HTML. Themeable to your brand.
For ISPs & installers
Branded diagnostics for support teams and field technicians, with shareable result links to settle 'is it the line or the home?'.
One call, a full diagnosis
Authenticate, request a panel, and get back structured results plus a plain-language verdict and a shareable report URL. REST, JSON, and a widget you can theme to match your brand.
- Pre-sales line checks on an ISP landing page
- In-app diagnostics for routers, mesh and apps
- Support tickets with a one-click connection report
- Field installer verification before sign-off
