In short
AccessGO combines a plugin for visitors, automatic optimisations via script, audit and monitoring and an accessibility statement in annual packages. Easy read (Leichte Sprache), PDF remediation, manual audits and workshops are available in addition. Accessonaut offers a permanently free start, monthly prices and a workflow in which you fix findings yourself in the source code or CMS.
What AccessGO offers
According to AccessGO’s public pages, the offer includes:
- Website plugin: Menu for visitors with more than 25 settings according to the vendor, added via a JavaScript snippet. Source: Website plugin at AccessGO
- Auto-optimisation: AI-based adjustments, including alt text, keyboard operation, skip links and focus. Source: Auto-optimisation at AccessGO
- Audit & monitoring: Shows barriers and provides actionable steps, also as a report. Source: Audit & monitoring at AccessGO
- Accessibility statement: Generator for the accessibility statement. Source: Accessibility statement at AccessGO
- Browser assistant: Highlights barriers directly on your own website. Source: Browser assistant at AccessGO
- Further services: Including PDF remediation, easy read, videos in German Sign Language, manual audits and workshops. Source: Further services at AccessGO
How the approaches differ
AccessGO combines a plugin for visitors with automatic optimisations that take effect on the website through the AccessGO script, such as AI alt text or labels for screen readers. The vendor names limits itself: not all barriers can be detected automatically, and ARIA labels, forms and the heading structure are not adjusted automatically but are detected by the monitoring.
Accessonaut starts with the cause: scan pages, understand findings with their location and WCAG reference, fix them in the source code or CMS, check again and maintain the statement. The optional widget offers personal reading aids and can deliver approved alt text. There is no blanket automatic repair.
Both vendors offer a statement generator and a browser assistant. The differences lie mainly in the pricing model, the services and whether automatic adjustments in the browser are part of the package.
Nein, die Funktionen des Plugins decken aber viele der häufigsten und wichtigsten Barrieren ab, auf die Ihre Nutzer stoßen könnten.Translation: No, but the plugin’s functions cover many of the most common and most important barriers your users might encounter.

When AccessGO may fit better
- You want plugin, automatic optimisations, statement and audit in one annual package from a German vendor.
- You need easy read, videos in German Sign Language, PDF remediation or workshops from the same vendor.
- You look after a municipality or public body and want services that AccessGO explicitly tailors to this audience.
When Accessonaut fits
- You want to start permanently free or begin monthly with small amounts.
- Your team fixes findings itself in the CMS or source code and wants to prove progress with re-checks.
- You deliberately want to avoid automatic changes in the browser; by default, the widget only delivers alt text after your review.
- As an agency, you look after several projects in one account.
What independent bodies say about overlay tools
- The German federal and state monitoring bodies write in their joint assessment (March 2025):
Ein nicht barrierefreier Webauftritt wird durch den Einsatz eines Overlay-Tools nicht zwingend barrierefrei gemäß den gesetzlichen Anforderungen.
(An inaccessible website does not necessarily become accessible under the legal requirements by using an overlay tool.) Source: BFIT-Bund: assessment of the monitoring bodies on overlay tools (March 2025, German) - The German Federal Accessibility Agency (Bundesfachstelle Barrierefreiheit) states that an online shop cannot meet its digital accessibility obligations under the BFSG with an overlay tool. Source: Bundesfachstelle Barrierefreiheit: e-commerce and the BFSG (German)
- In 2023, the European Disability Forum (EDF) and the IAAP stated that overlays do not make a website accessible or compliant with European legislation and are no substitute for fixing the website itself. Source: EDF and IAAP: Accessibility overlays don’t guarantee compliance with European legislation (2023)
- The W3C points out that evaluation tools cannot determine accessibility, they can only assist. This also applies to automated scans like ours. Source: W3C WAI: Selecting Web Accessibility Evaluation Tools
- The Overlay Fact Sheet, a statement signed by more than a thousand accessibility practitioners and organisations, advises against using overlays as a long-term solution. Source: Overlay Fact Sheet
These assessments concern overlay and widget solutions in general, including the Accessonaut reading-aid widget. That is why our widget is optional and does not replace fixes in the source code.
