Integrates & Works with Your Entire Stack:

Roll Up Your Sleeves & Get Coding!

Convert Experiences had a vision -- to be like a box of Legos. 15 years & 40,000 sites later, developers say we succeeded.

Anti-Flicker Technology

Our lightweight snippet has a built-in anti-flicker shield.
Prevents visual disruptions that impact UX and skew test results, reducing your debugging time.
No flicker doesn’t mean we compromise page load speed and performance. See how Convert keeps the balance.

Version Control

No 3:00 AM in the morning pings because unvetted tracking snippet changes have broken experiments!
Our version control widget allows you to manually accept changes to the tracking script before they are implemented. Higher plans even allow you to schedule updates.

API-First Architecture

Full-coverage REST API lets you create, update, and report on experiments, goals, and collaborators — from a script or CLI.
Programmatic control means you can version, QA, and roll back tests entirely inside your own tooling and workflows.
CI/CD-friendly: Call the API (or the Full-Stack JS SDK for runtime evaluation) in your pipeline to roll out changes with fewer manual steps and lower risk.

MCP Server for Prompt-Based Test Development

Turn your favorite AI tool into your Convert co-pilot (One you’ll actually use!)
Automate experiment management with natural language. Your AI assistant can create, update, or pause experiments, adjust traffic splits, or inspect targeting rules from your editor or chat environment to reduce manual coding overhead by 60%.
Use AI safely with least-privilege access and local-only credentials.
Maintain line-by-line code visibility, because AI can never replace your reasoning & judgment.

5 Flexible Code Editors

Global Experience CSS editor.
Variation CSS editor.
Variation JS editor — Lets you insert custom Javascript that applies per variation.
Global Experience JS editor — Works the same as the Variation JS editor, but the inserted Javascript applies across all the variations.
Global Project Javascript editor.

Go as Deep & Technical as You Like

The depth and capabilities of Convert Experiences for experimentation just blew me away. Convert knows that one size does _not_ fit all, and have provided so many places to inject a script at runtime to be able to decide when and how to run an experiment. This is so huge for me because the app I experiment on is written with wildly changing view layers. The specific feature I'm describing is called 'JS Conditions' or DMP Profiling.

I've used Adobe, Optimizely, Google experiments, etc. and none of them really let you get your hands dirty with the code like this tool.

FAQ

Frequently Asked Questions

Is it possible to do prompt-driven experimentation with Convert Experiences?

Yes. If by prompt-driven experimentation you mean keeping the human in the loop and taking over tedious coding tasks that add 60% of overhead to the work of developers.

Our powerful MCP server is used by the most experienced experimentation agencies on the planet to set up granular, impactful reporting and to build experiment variations, with tools you already trust — like Claude Code and Cursor.

If you want AI to do it all – from start to finish, and use the output as production-ready variants, instead of prototypes – no. We do not encourage vibe experimentation.

How do I implement the Convert snippet on my website?

To implement Convert, place the lightweight snippet in your site’s <head>.

It includes built-in anti-flicker protection and supports asynchronous deployment. For advanced use cases, Convert offers server-side SDKs and framework-specific guidance for React, Vue, and SPAs.

Can I run tests across multiple subdomains?

Yes, Convert supports testing across multiple subdomains of the same root domain. Audience data, goals, and experiences remain consistent using first-party cookies shared across subdomains.

Does Convert support SPAs or Vue/React setups?

Yes, Convert works with SPAs and modern frameworks like Vue and React.

Are there discrepancies between numbers in analytics tools & Convert Experiences? How can we resolve them?

Yes, discrepancies can occur due to differences in how tools define and trigger conversions. Convert provides detailed explanations and offers guidance for aligning GA4 and platform-specific tracking logic.

How does Convert work with third-party apps?

Convert integrates with over 90 third-party apps, including GA4, Segment, and HubSpot. Also exposes JavaScript hooks that let you forward Convert events to any other platform you use.

What is Convert’s impact on site speed?

Convert has minimal impact on site performance. The snippet is about 60 kB transferred over network, loads synchronously by default for a seamless experience with no flicker, and supports asynchronous loading with a small anti-flicker snippet for even faster performance.

What are the different debugging tools Convert has to offer?

Convert offers a Chrome Debugger extension, real-time variation previews, console logging, and in-app diagnostics. These tools help identify issues with targeting, code, or experiment configuration.

Can Convert be implemented on headless stores?

Yes. Convert’s Full-Stack JavaScript SDK is framework-agnostic and API-backed, so you can evaluate experiments server-side (or at the edge) in any headless or Jamstack stack—Hydrogen-powered Shopify included. Instantiate the SDK before rendering, pass your own customer/session IDs, and you’ll get accurate attribution with zero flicker and full SSR compatibility.
