Comparison · Enterprise fraud-decisioning platform
Vouchley vs Sift
Sift is the enterprise-grade fraud platform — payments, signups, content, account takeover, all in one ML system. Vouchley is the focused, developer-priced alternative for teams that just need signup verification.
Sift is genuinely impressive. It's one of the most capable fraud platforms on the market — payments fraud, account takeover, content abuse, signup fraud, all powered by a shared ML model trained across the entire customer base. It's also priced for buyers with procurement teams. Public reports put typical Sift contracts at $30,000–50,000 per year minimum, and enterprise deployments at $100,000–300,000+. Vouchley starts at $29.

Quick verdict
Pick Vouchley if…
- You're a startup, indie team, or mid-market SaaS where a five-figure annual contract isn't on the roadmap.
- Your fraud surface is signup-only — you don't have payments fraud, content abuse, or ATO problems to solve in the same platform.
- You want to ship the integration this afternoon, not after a six-week sales cycle.
Pick Siftif…
- You're an enterprise with multiple fraud surfaces (signup + payments + content + ATO) and need one ML platform to score them all.
- You have a fraud ops team that wants a full investigation UI, case management, and analyst tooling.
- Your annual fraud loss is in the seven figures and a $50k+ platform pays for itself.

Pricing, side by side
Vouchley
Vouchley is priced like a developer tool: $29 for 3,000 verifications, no monthly minimum, no contract, sign up with email and start in 5 minutes.
Sift
Sift doesn't publish pricing. Vendor-research sites report typical contracts at $30k–50k/year minimum, with enterprise deployments at $100k–300k+. Pricing combines per-API-call volume, feature modules, and multi-year commits. Expect a sales cycle.
Sample scenario
Series A SaaS, 50,000 signups/month
- Vouchley
- Roughly $400/mo on credit packs
- Sift
- Five-figure annual contract; not Sift's target buyer
When Sift is the better pick
If you're a marketplace, payments company, or social platform with multiple fraud surfaces and an actual fraud team, Sift's network-effect ML and unified platform are very hard to replicate with point tools. The price tag matches the scope. For that buyer, Sift earns its keep.
When Vouchley is the better pick
Most teams shopping for signup verification don't have a $50k/year fraud budget. They have a signup form that's filling up with disposable emails, and they need to fix it this week. Vouchley fits that buyer: API-first, single use case, predictable pricing, no procurement.
Frequently asked
- Why is Sift so much more expensive?
- Different products. Sift is a multi-surface fraud platform — payments, signups, ATO, content abuse — with a network-effect ML model and an analyst UI. Vouchley does only one of those (signup verification) and prices accordingly. If you only need signup verification, you'd be paying for a lot of unused Sift surface area.
- Will Vouchley scale to enterprise volume?
- Vouchley handles tens of thousands of verifications per minute on the standard tier and is built on FastAPI + Postgres with horizontal scaling. If you need a custom rate-limit ceiling or EU data residency, that's available on the Pro/Scale plans.
- Can I use Vouchley alongside Sift?
- Yes. Some teams use Vouchley as a fast pre-filter at signup to drop obvious abuse cheaply, then send only the harder cases to Sift's fuller decisioning. That cuts Sift's per-call spend significantly.
