# Why VWO Users Switch to Code-Native A/B Testing

> VWO is a genuinely capable visual editor. Teams that move away tend to do it for one specific reason — the winning variant never actually lived in their codebase.

Growth teams that move away from VWO for landing page tests tend to cite one recurring reason: the winning variant lives inside VWO's runtime layer, not in the actual page source, which means shipping the winner permanently requires a second implementation step — someone on engineering has to rebuild what already worked once as real code. VWO itself rates well (4.4–4.5/5 on G2 across roughly 927 ratings) and its visual editor is genuinely fast for building a test without engineering help. The friction shows up after the test, not during it.

This is Landtest's own content.

## The pattern behind the switch

A marketer builds a test in VWO's editor, it wins, and then "shipping the winner" means either leaving VWO's script running in production indefinitely (which some reviewers connect to the rendering delay complaints on complex layouts) or asking engineering to rebuild the winning version as real committed code. Neither is ideal: the first means your site depends on a third-party script for something that's no longer actually being tested, and the second is duplicate work plus a chance for the rebuilt version to drift from what was actually tested.

The second common driver is the "quirky on complex layouts" complaint reviewers raise — for teams whose landing pages are more structurally dynamic than a typical marketing page, the visual editor's DOM-injection approach gets harder to manage reliably as complexity increases.

## What switching actually changes

Moving to a code-native approach means the variant is real code from the start — reviewed as a preview, not built in an editor layer — so "shipping the winner" is just merging the branch that already won. For a growth team working alongside engineering (which most teams past early seed stage do, at least for anything structural), that removes the rebuild step entirely.

## When staying on VWO makes more sense

If your growth team operates largely independently of engineering and needs to ship tests without a PR review cycle, VWO's visual editor remains the faster path to a live test, and the rebuild-after-winning cost may be worth that independence.

## FAQ

**Does the winning VWO variant automatically become the live page?**
Not automatically in the sense of becoming committed source code — the test runs via VWO's script, and making the winner permanent typically means implementing it directly in your codebase afterward.

**Is VWO bad for complex landing pages?**
Not bad, but reviewers do note the visual editor can get "quirky" on complex or highly dynamic layouts, which is worth testing directly on your actual page before committing.

**Can VWO and code-native testing coexist?**
Some teams use VWO for fast, marketer-led tests on simpler pages and a code-native tool for pages that already go through engineering review.
