Honest by design

What each of them is for

Siteimprove is an established enterprise platform for website governance: accessibility, content quality assurance, enterprise SEO and digital analytics, sold with services and training and priced by individual quote. For large organisations with compliance duties it is a strong, proven choice.

Astrina covers the day-to-day essentials of the same job — SEO audits with daily monitoring, automated accessibility checks, analytics with session replay, plus things Siteimprove does not aim at: uptime and synthetic monitoring from a distributed device network, and embeddable widgets from lead forms to an AI assistant. Everything is self-serve, from a free plan.

The short answer

The honest split: if you need a full accessibility programme with expert services and organisation-wide governance, Siteimprove is built for that. If you want the practical toolkit — measure, monitor, fix, convert — in one place at a price a small team can approve, that is Astrina.

Feature by feature

Row by row, both columns

Both columns are honest: where Siteimprove is stronger, the table says so.

✓Full support ±Partial —Not offered
CapabilityAstrinaSiteimprove
Web analytics + session replay✓Privacy-first analytics, goals, Core Web Vitals; session replay with heatmaps and struggle detection on Business plans.±Digital analytics with behaviour insights; session replay is not an advertised product.
SEO monitoring✓Site audits, daily page monitoring, keyword tracking and copy-paste AI fixes.✓Enterprise SEO suite with content and technical checks.
Accessibility testing±Automated WCAG checks, PDF checks and a statement generator; contrast, focus and keyboard need manual review — the report says so honestly.✓Their flagship: deep automated and expert-led accessibility, training and certification.
Content quality assurance±Broken links, policy rules (forbid/require phrases) and content originality checks; no spell-checker.✓Mature QA: broken links, misspellings, style and policy across large sites.
Uptime & synthetic monitoring✓Seven check kinds, browser journeys, incident screenshots — confirmed from real devices in many countries by the Pulsar network.—Not part of their product.
Embeddable widgets✓Lead forms, cookie consent, comments, share, guided tours and an approved-answers AI assistant — one script tag.—Not part of their product.
Price✓Free plan; paid self-serve plans from €19/mo (Pro), €59/mo (Business).±By individual quote; enterprise contracts, no public self-serve pricing.

Where Siteimprove is stronger

Accessibility depth is theirs: expert audits, remediation services, academy training and certification, plus organisation-wide governance, benchmarking and enterprise support. Astrina automates the mechanical WCAG checks and is honest about what automation cannot see — it does not replace a full accessibility programme.

Where Astrina is stronger

Session replay, uptime and synthetic monitoring, status pages and drop-in conversion widgets are all things Siteimprove does not offer — and Astrina bundles them with SEO and analytics on self-serve plans that start free. You can be running in minutes without a sales call.

Questions we hear

Frequently asked questions

Is Astrina a full replacement for Siteimprove?

For enterprise accessibility governance with expert services — no, and this page does not claim it. For the practical overlap — SEO monitoring, automated accessibility checks, content policy rules, analytics — Astrina covers the daily work, and adds uptime monitoring, replay and widgets that Siteimprove does not have.

Does Astrina check accessibility like Siteimprove does?

Astrina runs automated WCAG checks on your pages and PDFs and generates an accessibility statement. Automation cannot judge contrast in images, focus order or keyboard flows, and the report marks those honestly for manual review. Siteimprove goes further with expert-led audits and training.

How do the prices compare?

Astrina is self-serve: a free plan, Pro at €19/mo and Business at €59/mo. Siteimprove does not publish prices — plans are quoted individually and are aimed at enterprise budgets. If you have a compliance mandate and the budget, a quote is worth getting; if not, you can start on Astrina today for free.

Can I try Astrina before paying anything?

Yes — the free plan needs no card, includes three sites, analytics, SEO checks and a monitor, and never renews into a paid plan by itself.
