axe DevTools vs IBM Equal Access Toolkit
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Open sourceWhat drives the bill
The metric that actually scales your invoice.
The free extension covers a lot. Deque no longer publishes a price for Pro or the axe DevTools for Web bundle — both route through sales or a no-card trial, so budget from a quote rather than a list price.
Free and open source. You pay in engineering time and CI minutes.

Strengths
- Guided manual testing addresses the two thirds of WCAG that scanners cannot.
- Findings come with concrete code-level remediation advice.
- Deque's accessibility expertise is the deepest in the industry.
- Completely free including CI integration and reporting.
- Guidance is written for developers with concrete code examples.
- Includes design and content guidance beyond the code checker.
Limitations
- Per-seat pricing adds up across a large engineering organisation.
- The free extension is good enough for many teams, blurring the upgrade case.
- Enterprise deployment needs process design, not just a licence.
- Smaller community than axe-core, so fewer worked examples.
- Reporting is basic compared with commercial platforms.
- Rule set differs slightly from axe, which can confuse cross-tool comparisons.
Best for
