Which version sells better: “Launch Fast” or “Ship Instantly”?
Test your headline and CTA text.
One script. One dashboard. Zero guesswork.
<script src="https://cdn.ablight.dev/ab.js?id=YOUR_PROJECT_ID"></script>Variants & goals load from the server — no redeploys.
Ship Instantly
Minimal, selector-based A/B for headline & CTA. No HTML surgery. Real conversions.
Impact First
Headline & CTA are the highest-leverage elements. Stop arguing; measure.
Frictionless
One script. Pick elements with CSS selectors. No HTML edits, no redeploys.
Real Conversions
Click, success URL, or JS trigger after a signup/checkout event.
What we’ll build if there’s demand
- • One-line script. Configure tests from the dashboard (CSS selectors, A/B copy).
- • Real conversion goals: Click · Success URL · JS trigger after signup/checkout.
- • Fast, privacy-respecting: no heatmaps, no replays, no third-party API keys.
- • Simple reporting: Views, Clicks, Conversions, CR%, clear winner.
- • Zero redeploys: change variants/goals without touching your codebase.
We don’t want to build yet another bloated A/B tool. If founders like you want a headlines & CTA-only weapon, we’ll craft it. If not, we won’t waste your time.

Frequently Asked Questions
Why not use big tools like Unbound, Growbook, etc.?
Those tools are powerful, but they're like a heavy-duty truck: bloated, expensive, and they slow down your site. ABLight is a Formula 1 car: hyper-lightweight, obsessively focused on one job (testing headlines & CTAs), and does it better than anyone. Not having a heatmap or a pop-up builder is a feature.
I'm a dev, why not just build this myself?
You absolutely could. But a robust A/B testing system isn't just `Math.random()`. It needs a reliable stats engine, anti-flicker mechanisms, persistent user bucketing... ABLight handles all of that. For the proposed price, you're buying back dozens of hours to focus on your core product.
Is this live?
Not yet. This is a validation page. If enough builders want it, we’ll ship the MVP and invite you first.
Will it track “real” conversions?
Yes — Click (by selector), URL (success page), or a JS trigger you call after signup/checkout.
Any heavy SDKs or API keys?
No. One tiny script. No heatmaps or replays. No third-party API keys required.
Pricing?
We’re exploring $9–$19/mo and a $49 lifetime. Tell us what you’d pay in the form above.

You know that moment when you realize you’re spending more time fighting with your tools than actually improving your product? I had that moment. As a solo developer, that’s a cardinal sin. Lost in a sea of complex dashboards, I asked myself, 'Why isn’t there a tool that just focuses on the two things that drive 80% of success: the headline and the CTA?' ABLight was born from that question. It’s not a tool for everyone. It’s a tool for us—the solo builders, the makers who need speed and ruthless efficiency. I built it for myself, and I have a feeling you need it too.
