Our A/B testing tool works with SPA by loading using URL change or monitoring for specific DOM changes.
Single page applications need tests that understand route changes, delayed DOM rendering, and dynamic components. Mida helps teams test modern websites without giving up marketer control.
Target experiments to SPA routes, campaign URLs, and important page states so visitors see the right variant even when navigation happens client-side.
Use visual edits for simple changes and custom code when you need to wait for components, change stateful UI, or handle dynamic content.
Give growth teams a safe workflow for testing headlines, layouts, forms, and CTAs on React, Vue, Webflow, Framer, or other modern frontend sites.
SPA experiments need clear triggers and stable targeting. Mida keeps the setup understandable for marketers while still giving technical teams control when needed.
No. Mida is best for client-side website and marketing experiments. SDK-based feature experimentation is better for backend logic, native apps, and deep product features.
Yes, as long as the site allows custom JavaScript. Mida can target routes and apply variants after dynamic content renders.
Start with navigation, onboarding steps, forms, pricing CTAs, page-level messaging, and other changes that do not require backend logic.

Tested users are individuals who visit your website and are included in any of the A/B tests you're conducting. We have created an easy visualization of MTU here.
Mida counts an MTU when a unique visitor interacts with at least one active experiment within a billing month. Each user is counted only once per month, regardless of how many experiments they participate in or how many pages they view. Click here to learn more.
For most teams, 5 projects are more than enough. We typically see customers using 1–2 projects (for example, one for a landing site and one for an app). If you need more than 5 projects, you’re likely managing multiple sites or clients. Reach out to us about our Agency plan, which is better built for that use case.
Mida is designed to have minimal impact on your site speed. Our script is 15KB compressed and typically much smaller and faster than most competitors, keeping your website's performance smooth. You can see a detailed comparison of script and loading times here.
