Useful first-party and suggestion-based discovery, but not positioned as a full standalone keyword database.
Sitechecker lists Google Search Console keyword suggestions, Google autocomplete search suggestions, and competitor keywords, with plan-specific monthly checks. https://sitechecker.pro/account/plans/

Technical SEO
Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
Frase
Site auditing and page-level SEO readiness are present, but the reviewed first-party material does not establish a full technical crawler suite.

Value accessibility
Buying
How easy it is for a team to reach value relative to pricing, setup complexity, and required expertise.
Frase
Self-serve plans begin at a public price with a no-card trial, though meaningful scale is paid.
The homepage says self-serve from day one and the pricing page publishes Starter at $39/month yearly with a 7-day no-card trial. https://www.frase.io/pricing
Sitechecker
Public monthly/annual pricing and free trial improve access, but entry pricing is agency-oriented.
The public plans page lists Basic at $99 monthly/$83 annual, offers try-for-free CTAs, and gives a 48-hour money-back policy. https://sitechecker.pro/account/plans/
Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.

A free trial and free FraseCMS hosting are available, but the core product is not a permanently free plan.

Sitechecker
The vendor provides a free on-page checker and Chrome extension, but the core platform is paid.

The pricing page says “Thousands of teams already run on Frase.” https://www.frase.io/pricing
Sitechecker

The product has a named AI SEO Agent with natural-language workflows, API, and automation hooks.
The agent page describes research, briefs, drafts, scores, clustering, repurposing, and publishing in one chat; the API page describes REST API and webhooks. https://www.frase.io/features/agent https://www.frase.io/features/api-integrations
Sitechecker
Public REST API, API keys, documented endpoints, and webhook-triggered audits create a strong automation surface.
The official docs describe a Public REST API for projects, GSC/GA4 performance, rankings, and AI visibility; pricing lists audit-via-webhook automation. https://docs.sitechecker.pro/guides/getting-started/ https://sitechecker.pro/account/plans/
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
Frase
Autonomous publishing and approval-based Content Guard fixes are explicit, with customer rules controlling what goes live.
The agent page says publishing occurs on approval and Content Guard proposes fixes for approval; pricing says the agent can publish on its own when enabled. https://www.frase.io/features/agent https://www.frase.io/pricing
Sitechecker
Scheduled recrawls, alerts, reports, and webhook/API access automate monitoring, but no end-to-end autonomous remediation is claimed.
Sitechecker says sites can be automatically crawled on a custom schedule and critical changes generate email/Slack alerts; its API exposes data rather than claiming autonomous fixes. https://sitechecker.pro/website-monitoring/ https://sitechecker.pro/seo-alerts/ https://docs.sitechecker.pro/guides/getting-started/
