BuildWhy teams switch
Most teams piece together testing, tracking, and workflow tools. CROTool.com combines them all in one place.
VWO Testing
Starts at $314/mo for the Growth plan. Pro plan is $972/mo. Enterprise is custom. Each product (Testing, Insights, Personalize) is priced separately — most teams need at least two.
Jira + Airtable
Jira Standard is $9/user/mo, Premium $18/user/mo. Airtable Team is $20/user/mo, Business $45/user/mo. For a 5-person team: $145/mo minimum for both.
CROTool.com
No per-user fees, no traffic limits, no feature gates. Includes everything: visual editor, GTM deploy, GA4 tracking, kanban, idea backlog, AI builder, and team management.

How it works
Type a rough idea. AI turns it into a polished hypothesis with a clear KPI and suggested title.
Use the visual editor to make CSS, text, or HTML changes — or let AI generate them from a screenshot.
One click deploys your test as a GTM container. Preview in GTM, then publish when ready.
GA4 tracking is auto-configured. AI reads your results and gives a clear ship or don’t ship recommendation.
AI-powered
AI writes your hypothesis, generates variant code from a screenshot, and interprets results with a clear recommendation. You stay in control — AI does the heavy lifting.

Everything you need
Whether you're in marketing, product, growth, or CRO — if you have an idea, you can test it. No technical skills required.
Build variants with CSS, text, or HTML changes. No code, no Jira tickets, no waiting for the next sprint.
Export a ready-to-import GTM container and go live. No manual tag setup, no DevOps.
Tracking is auto-configured. Open your existing Google Analytics and filter by experiment.
Generate polished test briefs from a rough idea, build variants from screenshots, and get a clear ship/don't ship recommendation when results come in.
Kanban workflow takes every test from idea → build → preview → live → analysis → done.
Score ideas by ease and impact. The highest-value tests rise to the top automatically.
Marketing, product, growth — each team gets separate tests, members, and GTM accounts.
See exactly how your variant looks on the real page. Catch issues before real users do.
Chrome extension lets you point and click on any element. No digging through source code.
For leadership
Your team runs tests independently. No Jira tickets, no sprint planning, no waiting for the next release.
Teams that test more, learn faster. Remove the bottleneck and 10x your experimentation velocity.
Uses your existing GTM and GA4. Your data stays in Google. Switch away anytime — nothing to migrate.
Replaces VWO, Jira boards, and Airtable trackers with a single tool purpose-built for experimentation.
Every change you make to your website is a guess — until you test it. Teams that run A/B tests make decisions based on data, not opinions. The result: higher conversions, less risk, and faster growth.

FAQ
No credit card required to get started. The tool uses your existing Google Tag Manager and GA4 — there's no complex infrastructure on our end.
Yes, GTM is how tests get deployed to your site. If you don't have GTM yet, it takes about 5 minutes to set up — and your developer only needs to add the GTM snippet once. After that, you're fully independent.
Your test data stays in your own Google account. We never see your analytics data. Tests are deployed through GTM, and results are tracked in your GA4 property. We only store test configurations.
No. Tests are injected via GTM which is already on your site. The variant code is lightweight CSS/JS that runs in milliseconds. We also include an anti-flicker snippet to prevent layout shifts.
No. The visual editor lets you make CSS, text, and HTML changes without writing code. For more complex changes, AI can generate the variant code for you from a screenshot or description.
Results appear in your existing Google Analytics (GA4). We auto-configure the tracking events and custom dimensions — just open GA4 and filter by experiment.
