Accessibility / A11y Testing
The clearest split between Stark and WebAIM is cost: Stark offers a free tier with paid upgrades (pricing not public), while WebAIM is free to use. Stark is design-tool accessibility plugin for Figma, Sketch, and Adobe XD (contrast, vision sim). WebAIM is nonprofit web accessibility training, free resources, and the WAVE evaluation tool. Pick Stark when the job is design teams catching a11y issues in figma before engineering and you accept medium lock-in; pick WebAIM when it is any team that needs reliable a11y reference material and the free wave checker and you accept low lock-in. The data we have shows Stark at mostly transparent pricing and docs with average developer experience, and WebAIM at fully public pricing and documentation with solid developer experience. The honest trade-off: neither is universal — Stark is a poor fit for teams wanting automated scans of production web apps, and WebAIM is a poor fit for enterprises wanting a single vendor-managed monitoring platform. Match the pricing model and lock-in level to how your team actually works, not the feature list.
Quick take
Stark is for design-tool accessibility plugin; WebAIM is for nonprofit web accessibility training; decide based on budget vs. support.

Neither Stark nor WebAIM publishes entry pricing that lets us compare directly — Stark uses a freemium model and WebAIM uses a free model. Get quotes from both before assuming one is cheaper.
Migration is possible in either direction. Stark carries medium lock-in and WebAIM carries low lock-in, so plan for meaningful but not blocking rework. Run both in parallel before you fully cut over.
WebAIM scores higher on developer experience in our data (4/5 vs 3/5). The gap usually shows up in setup friction and daily workflow speed. Confirm it on your own stack before treating the rating as final.
Yes — WebAIM is a reasonable alternative to Stark for design teams catching a11y issues in figma before engineering.. The practical differences are freemium-vs-free billing and medium-vs-low lock-in. If those fit your constraints better, treat WebAIM as a credible swap.
