The short version

  • Each has a real cost: Frase the entry-level Starter plan is capped at a single seat and site, which limits it to solo users rather than small teams.; SISTRIX coverage is deepest in German-speaking Europe and thinner in the United States and Asia, so international teams still need Ahrefs or Semrush alongside it.
  • They diverge on capability: Frase covers Content briefs and outlines, SISTRIX covers Visibility Index.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Frase

  • The entry-level Starter plan is capped at a single seat and site, which limits it to solo users rather than small teams.
  • Overage charges apply per extra article or audit page once monthly plan limits are exceeded on Professional and Scale.
  • Free trial features are limited to Professional-tier functionality for 7 days rather than reflecting the full product.

SISTRIX

  • Coverage is deepest in German-speaking Europe and thinner in the United States and Asia, so international teams still need Ahrefs or Semrush alongside it.
  • The Visibility Index is domain-level, so a dramatic chart movement can come entirely from pages that carry no commercial value and requires drilling down before it means anything.
  • The link index is smaller than the market leaders, which matters if backlink discovery rather than visibility measurement is your main use.
  • Modules are priced individually, so a team that needs SEO, links and the Optimizer pays a multiple of the entry price for one module.
  • Documentation, community material and support are German-first, and while English is available the depth of the two is not equal.

SISTRIX: What is the Visibility Index actually measuring?

Rankings for a large fixed keyword set per country, weighted by expected traffic, measured weekly. It is not your keyword list, which is what makes it comparable.

Frase: Is there a free trial?

Frase offers a 7-day trial with Professional-level features and no credit card required.

Source
SISTRIX: Can it replace Ahrefs or Semrush?

For German-language visibility reporting and competitor history, yes. For global keyword research and backlink analysis it is a complement rather than a replacement.

Frase: What happens if I exceed my plan's usage limits?

Professional and Scale plans support optional pay-as-you-go overages, disabled by default, charged per extra article or audit page beyond the monthly cap.

Source
SISTRIX: How far back does the data go?

To 2008 for the earliest supported countries, which is longer than any rank tracker can offer on your own keyword list.

Frase: What does Frase integrate with?

Frase publishes content to WordPress, Webflow, Sanity, and Wix, or can host pages directly via its own FraseCMS.
