“Installed Splitstream two months ago. It took our sign-up CVR from 2.1% to 5.3%, around $8,700 in extra MRR we wouldn't have had otherwise.”
“We'd tried split testing before, but it took too much time and effort. Splitstream takes all of that away. Six weeks of compounding small wins later, our conversion rate is up 4% overall.”
Splitstream, testing Splitstream.
The champion is the headline you just read. The challenger is one Splitstream generated — and it's winning.
Three minutes of setup. Then never again.
Your first test is free, start to finish. Everything after it is the loop doing its job.
Paste your URL. Splitstream reads your live page and ranks the changes most likely to lift your conversion rate. The top one becomes test #001.
Connect GitHub and approve two pull requests, or skip GitHub entirely: copy two snippets, or paste a prompt into Cursor or Claude Code. Your main branch stays protected either way.
Visitors split 50/50 between your page and the variant. Splitstream tracks conversions live and watches guardrails: bounce, speed, errors.
The moment a result is conclusive, you get the call. Approve it and the winner ships; the next test queues itself against the new baseline.
Other tools wait for you. Splitstream doesn't.
Testing tools sit idle until someone picks the next idea, builds it, and remembers to check the stats. Splitstream runs the champion versus challenger loop for you, forever.
The highest-leverage change on your page — chosen for you.
Writes the variant as real code. Your devs review and approve.
Splits real traffic A/B, decided with Bayesian statistics.
Merges to main. Your conversion rate steps up — for good.
Then it does it again. A fresh test every week — the loop never stops while you're subscribed. You just approve the PRs.
Same traffic. Compounding conversions.
Each winner becomes the new baseline and the next test runs against it. Lift conversion from 2% to 4% and you have doubled sign-ups on the exact same visitors. No extra traffic, no extra ad spend.
Your code and your data, never out of your control.
Splitstream works inside the review flow you already trust. Scoped access, changes you approve, and a clean revert whenever you want one.
Scoped, read-only access to a single repo. Nothing is written until you approve it.
Splitstream never edits your code directly. You get a PR with a full diff, like any other change.
You approve and merge it yourself. Splitstream cannot push to your main branch on its own.
Every change is a normal git revert away. If you don't like it, it's gone instantly.
Only the landing page file you point it at. No access to the rest of your codebase.
Cancel anytime. The tracking snippet and any Splitstream code come out as cleanly as they went in.
Bayesian winner detection with confidence calibrated to your traffic, sample floors, and guardrails on bounce, speed, and errors. No coin-flip winners. Your visitor data is never sold, shared, or aggregated.
Start free. Upgrade to keep testing.
Every plan installs the same way: GitHub PRs you approve, or two copy-paste snippets. Same price either way.
Run one complete test on your live traffic and see the winner for yourself.
