Why Marketing Teams Choose Mida

Most A/B testing tools are built for engineers or priced for enterprise teams. Mida was built for lean marketing and growth teams that want to test ideas fast without turning every copy change into a developer ticket.

No-Code Visual Editor

Click any headline, CTA, image or section and edit it directly. Test different value propositions, offers and layouts without touching HTML, CSS or JavaScript. Learn more about the visual editor.

Free Up to 100K Visitors

The Sandbox plan is free forever up to 100,000 Monthly Tested Users with no credit card required. Run experiments, measure conversions and improve your funnel without budget approval or procurement cycles.

One-Click GA4 Integration

Connect your GA4 property and your conversion events automatically become available as experiment goals. No custom event setup, no Measurement Protocol configuration and no GTM tags required. Verify results in the analytics you already trust.

Faster Than Developer-Led Testing

Move from hypothesis to live test in minutes instead of weeks. A developer adds the snippet once, then marketers can launch tests, adjust targeting and read results without waiting on the engineering backlog.

Lightweight 15KB Script

Mida uses a compressed 15KB script that loads in approximately 20ms. Protect your page speed and Core Web Vitals while running experiments. See the performance benchmark.

What Marketing Teams Test With Mida

The fastest way to improve conversion rate is to test the elements that influence buying decisions: copy, offers, social proof, urgency and visual hierarchy. Mida lets you test all of them without code.

Headlines and Value Props

Test which messaging resonates: product benefits, customer outcomes, problem statements, or social proof headlines.

CTA Copy and Colors

Test button text, color, size and placement. Measure whether urgency, clarity or benefit-driven CTAs drive more clicks.

Hero Images and Videos

Swap hero images, product photos or explainer videos. Test whether lifestyle imagery, product shots or customer faces improve conversion.

Pricing and Offers

Test pricing presentation, discount formats, free trial length or guarantee language. Measure revenue impact, not just clicks.

Social Proof and Trust Badges

Add customer logos, review counts, case study links, security badges or media mentions. Test which signals reduce buyer hesitation.

Form Length and Fields

Reduce form fields, test multi-step vs single-step signup, or hide optional fields. Measure completion rate, not just form starts.

How It Works

Marketing teams run Mida tests without touching code, but you still need a developer to add the snippet to your site head once. After that, you are independent.

1

Get the snippet installed

Ask a developer to add the Mida script to your site head. This is a one-time setup step that takes 5 minutes. After that, marketers can create tests without engineering help.

2

Open the page in the visual editor

Enter the URL you want to test. Mida loads your live page so you can point, click and edit directly on your actual site without a staging environment.

3

Make your changes

Click an element to edit text, swap images, change button colors, hide sections or inject new content. Repeat for as many changes as your hypothesis needs. Preview on desktop and mobile before publishing.

4

Set a goal and publish

Choose the metric you want to improve: signups, purchases, clicks, or a GA4 conversion event. Target by URL, device, traffic source or visitor segment. Split traffic and let the test run.

5

Read the results

Wait for statistical significance, then read which version drove more conversions, revenue or signups. Mida reports include conversion rate, improvement, confidence interval and statistical significance.

Frequently Asked Questions

Can I run A/B tests without a developer? +
You need a developer to add the Mida snippet to your site head once. After that, marketers can create test variants with the visual editor without code. For complex changes that need custom JavaScript or CSS, use the code editor or ask a developer for help.
Is Mida really free for marketers? +
Yes. The free Sandbox plan covers up to 100,000 Monthly Tested Users with no credit card required. Run experiments, measure conversions and improve your funnel without budget approval. Growth plans start at $224 per month billed annually when you outgrow the free tier or need features like AI variants, personalization or multi-workspace support.
What can I change with the visual editor? +
Change headlines, CTA text, button colors, images, backgrounds, spacing, visibility and layout. Inject trust badges, urgency messages, social proof or comparison tables. Hide distracting elements. For advanced changes like dynamic behavior or conditional logic, use the code editor or ask MidaGX to build the variant with AI.
Does Mida work with my analytics tool? +
Mida integrates natively with GA4. Connect your property in one click and your conversion events become available as experiment goals. Mida also integrates with Segment, Mixpanel, Amplitude, PostHog, HubSpot and other analytics platforms via webhooks or direct integrations. You can verify test results in the tools you already use.
Will Mida slow down my website? +
No. Mida uses a compressed 15KB script that is significantly smaller and faster than most competitors. The snippet loads in approximately 20ms and applies changes before visitors see the original content. Mida was designed to protect page speed and Core Web Vitals while running experiments. See the performance benchmark.
Can I use Mida on Shopify, WordPress or Webflow? +
Yes. Mida works on any site that allows custom HTML in the head section, including Shopify, Shopify Plus, WordPress, WooCommerce, Webflow, Wix, Squarespace, Framer, Unbounce, custom React and Vue apps, and static sites. For single-page apps, Mida supports URL-change and DOM-change triggers so tests reapply after client-side navigation.
How is Mida different from VWO or Optimizely? +
Mida is lighter, simpler and cheaper. VWO starts around $574 per month and retired its free tier. Optimizely targets enterprise teams with custom pricing and a developer-heavy implementation. Mida focuses on fast marketer-led experimentation: a 15KB script, a no-code visual editor, a permanent free plan up to 100,000 visitors, and AI-assisted variant creation through MidaGX.
