Quick answer
Yes — Splitpoint is a one-time-purchase alternative to VWO. It costs $49 once, while VWO runs $199/mo — about $2,388 per year, every year. Self-hosted experiments, a sub-3KB SDK and a real z-test — no per-visitor pricing. It is for people who want the job done on their own hardware without a renewal date — not for teams that live inside VWO's ecosystem.
The verdict
Switch to Splitpoint if you are an individual or small team paying VWO $199/mo for work your own machine can do. Less than one month of VWO covers Splitpoint forever — and it never tiers you by traffic.
Stay with VWO if your workflow depends on its integrations, you need enterprise features (SSO, admin controls, SLAs), or your team is large enough that per-seat collaboration tooling is worth the bill. Splitpoint does not try to replicate those.

Where VWO still wins
- Ecosystem and integrations. Established tools accumulate years of third-party integrations, templates and add-ons. If your workflow is wired into VWO's ecosystem, switching means rebuilding that plumbing — a real cost.
- Team and enterprise features. Shared workspaces, granular permissions, SSO, audit logs and a vendor to call when something breaks — that is what the higher subscription tiers actually buy, and a pay-once app does not come with it.
- Familiarity and hiring. VWO is the name people already know. Onboarding a team onto a tool nobody has used before takes time the subscription never charges for.
Where Splitpoint wins
- Price, permanently. $49 once versus $2,388/yr for as long as you use it. There is no renewal, no seat count and no tier gate.
- Experiments. Control plus N variants, weighted traffic split, holdout percentage, and URL/device targeting.
- Goals two ways. A JS track() call, or automatic conversion when a visitor hits a matching pageview URL.
- Tiny SDK. Vanilla JS under 3KB, no dependencies, never touches the DOM; assignments stick via deterministic hashing and localStorage so there is no flicker.
The math
Less than one month of VWO covers Splitpoint forever — and it never tiers you by traffic.
- After 1 year: Splitpoint has cost you $49 total — VWO has cost $2,388.
- After 3 years: Splitpoint is still $49 — the subscription is at $7,164.
- After 5 years: Splitpoint is still $49 — the subscription is at $11,940.
Common questions
Is it really free on GitHub?
Yes — Splitpoint is MIT-licensed at github.com/bensblueprints/ab-testing-tool-mvp. The $49 buys the packaged Windows installer and updates; building from source is free.
Can I trust the statistics?
It runs a pooled two-proportion z-test and reports the two-tailed p-value, confidence and Wald 95% CI. Standard caveats apply: fix your sample size up front, do not peek-and-stop the moment a result looks significant, and remember 1 in 20 winners at 95% is noise.
Is this a subscription in disguise?
No. $49 once, no renewal, no per-visitor metering. Your experiment data lives on your own server.
