Feature flags for controlled marketing and website rollouts

Mida feature flags help teams expose changes gradually, target who sees them, and reduce the risk of launching a website experience to everyone at once.

Release to a subset first

Roll out a new banner, offer, page section, or feature treatment to a limited audience before expanding.

Target by audience context

Use visitor, device, campaign, or page conditions to decide who should see a flagged experience.

Pair rollouts with experiments

Feature flags can support gradual release, while A/B tests help decide whether the new experience actually improves outcomes.

How flags fit with experimentation

VWO frames feature flags as rollout, testing, and personalization rules. Mida keeps that same practical idea focused on website and marketing use cases.

  1. Gate the experienceDefine what changes when the flag is on and who qualifies to see it.
  2. Control exposureStart with a small segment, campaign, or traffic percentage before expanding.
  3. Measure or personalizeTurn the flag into an experiment or use it as a targeted experience for the right audience.

Are Mida feature flags SDK-based?

Mida is primarily designed for website-side experience control. For backend logic, native mobile apps, or infrastructure flags, a dedicated SDK-based feature management platform may be a better fit.

Can flags reduce launch risk?

Yes. Flags let teams limit exposure, preview changes, and pause an experience without reverting a full release.

How are flags different from A/B tests?

A flag controls availability. An A/B test measures which version performs better. In practice, teams often use both together.

Frequently asked questions

What is Monthly Tested Users (MTU)?

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.

How does Mida count Monthly Tested Users (MTU)?

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.

Why does the Growth plan include only 5 projects?

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.

How does Mida affect my site speed?

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.

Can I use Mida for native Mobile Development?

It is in closed beta for now. Contact us through email to get into the beta testing for free.

Can it run on my website (Webflow/Wix/Framer/etc)?

Mida works with almost all websites that allow the addition of custom HTML codes.

Can it run on funnel sites?

Yes, it works on all website funnels that allow you to inject custom HTML codes to the HEAD section.

Do you support cross domain testing?

Yes, Mida supports cross-domain testing! You can use the same project snippet across different websites or domains. Add the unique project snippet to each site you want to test or track goals within the same project.

Do I need to pay separately for Live Deployment and Personalization?

No, it's all covered within the Growth plan. Our pricing plan doesn't charge you separately on features, it's purely a usage-based pricing model with all features covered.

Do you offer an agency portal to see all clients and results, or are clients on separate accounts?

Yes. Mida supports flexible agency setups, depending on how you work with your clients and handle billing. Click here to read more.
