Features

Everything your agency needs.
Nothing it doesn’t.

Purpose-built for teams managing A/B tests across multiple clients,
brands, and campaigns — all from one place.

Multi-Client Dashboard

Manage every client’s A/B tests from a single, organized workspace. Each client gets their own isolated data, snippet key, and experiment history.

Bayesian Statistics Engine

Know when a winner is a real winner. Our Bayesian engine runs 50,000 Monte Carlo simulations to give you real confidence — not misleading p-values.

Role-Based Team Access

Invite team members with owner, admin, or member roles. Data stays siloed per agency — your clients never see each other’s experiments.

Live Results Dashboard

Traffic splits, conversion rates, revenue impact, and confidence intervals — updating every 30 seconds so your team always has the latest picture.

Shareable Results & PDF Export

Generate a shareable results link for clients — no login required. Or export a PDF report showing conversion rates, uplift, and statistical confidence.

No-Code Test Builder

Create test variants without touching code. Change headlines, button text, colours, and more using a guided form.

How it works

From test idea to winning variant in minutes.

1

Connect your client’s site

Drop a single script tag into the client’s site header with their unique API key. Variantix starts tracking visitors immediately — no configuration needed.

2

Build your variants

Use the no-code builder to create test variants — change headlines, button text, colours, and more without writing a line of code.

3

Launch & monitor live

Activate the experiment and split traffic instantly. Watch conversion data update in real-time. Get an email alert the moment statistical confidence is reached.

4

Ship the winner, report the result

End the experiment with one click. Share a results link or export a PDF showing exactly how your test performed — ready to send to clients.

Early Access

Built with real agencies.

Variantix is being developed with direct input from CRO agencies

“Finally, a tool that gets how agencies actually work. Managing tests across multiple clients used to be a mess of spreadsheets. Variantix fixed that immediately.”

Sarah R.

Founder, CRO Agency

“As a solo CRO consultant, Variantix gives me proper infrastructure without enterprise prices. The Bayesian stats give me confidence I’m not calling winners too early.”

“The shareable results link is brilliant. Clients can see their live experiment data without needing a login — saves me having to screenshot and email reports every week.”

Optimizely and VWO are built for single brands with big budgets. Variantix is purpose-built for agencies — multi-client workspaces, per-client API keys, and team role management are core to the product. We’re also significantly more affordable, with pricing that makes sense for agencies managing multiple accounts.

Your clients just add a single lightweight JavaScript snippet to their site — two script tags in the head section, and they’re done. Each client gets their own unique API key so their data stays completely isolated. All test management happens in your Variantix dashboard.

The Variantix snippet is under 5KB and loads asynchronously, so it has no measurable impact on page speed or Core Web Vitals. Visitor assignment is cached locally, so repeat visits don’t require additional API calls.

Yes — you can generate a shareable results link for any experiment that gives clients a read-only view of their live data, no login required. For more involved clients, you can invite them directly to your workspace with a restricted role.

Unlike traditional frequentist A/B testing, our Bayesian engine runs 50,000 Monte Carlo simulations to calculate the probability that Variant B is genuinely better than the control. This gives you an intuitive “78% probability B wins” rather than a confusing p-value, and avoids the peeking problem that causes false positives.

Beta users lock in their pricing for life — your rate will never increase as long as you remain subscribed. Post-launch pricing will be higher, so getting in early is genuinely worthwhile.
