Best Sift Alternatives for SaaS

Sift is an enterprise fraud platform centered on payment fraud, chargebacks, and account takeover, sold as an annual contract. As of October 1, 2026, Sift doesn't publish a price. A SaaS team searching for a Sift alternative is often trying to stop fake signups and free trial abuse, not to staff a payments program.

There isn't one best replacement. Sift's competitors below split by that job. Dregs is an account-layer abuse prevention platform for SaaS signups and trials. It isn't a payment fraud or chargeback tool, and it doesn't replace Stripe Radar. If the loss is the charge, stay with Sift or your processor.

Sift Competitors, and Who Each One Is For

Most SaaS abuse never touches a payment. Use the row that names the loss you actually have, then read that tool. Buying a cheaper payments platform still leaves the fake signup in the user table.

Dregs

Who it's for: SaaS teams whose problem is fake signups, free trial abuse, and duplicate accounts, and who want a self-serve start instead of an annual contract.

Dregs scores every identity on four dimensions, Humanity, Authenticity, Uniqueness, and Behavior, updated moments after new activity. Scores are computed from your own traffic. There is no cross-customer consortium. Each score opens into its observations, so you can see exactly why and review a false positive without a support ticket. Custom rules and lists are how a borderline account becomes a limit instead of a block. Webhooks carry the result into your application, which is what produces less manual review. Dregs doesn't block or ban on its own. Your application does.

It isn't a payment fraud or chargeback tool, and it doesn't replace Stripe Radar. Sift can sit on the payment and the chargeback. Dregs sits on the account, including the fake user who never enters a card. Catching that account earlier can still reduce the payment fraud that follows. Dregs doesn't offer AML or KYC. The tracking script runs in the browser, including mobile browsers. A native app can send events through a server SDK, and those events don't carry a browser fingerprint.

Pricing is published and billed per active identity. Starter is $17/month for 100 active identities, Growth is $177/month for 5,000, and Advanced is $377/month for 10,000. Each plan includes a monthly checks allowance: 500,000 on Starter, 2,500,000 on Growth, and 5,000,000 on Advanced. On Dregs, a check is a score lookup for an identity you already track. Authenticity Check API calls are separate and count against the monthly operations quota. Event history is 90 days on Starter, 180 on Growth, and 365 on Advanced. The trial is 14 days and needs no credit card. API access and webhooks are on every plan. You can also investigate scores from Claude, ChatGPT, or Cursor. Current figures are on pricing. The two-product comparison is Dregs vs Sift.

SEON

Who it's for: fintech, payments, and iGaming fraud teams that need AML compliance and a deep digital footprint on an email or a phone, and that will work cases.

SEON is the Sift alternative when the missing piece is compliance, not a lower price for the same payments stack. A fraud check enriches an email, phone, or IP, with device and session monitoring around that check. The Premium tier adds customer screening, transaction monitoring, and case management. Dregs doesn't offer AML or KYC. If that is the requirement, SEON is the closer fit, and it publishes a Starter price where Sift publishes none. The wider SaaS shortlist on SEON's side is best SEON alternatives for SaaS.

As of October 1, 2026, Starter is $699/month for 2,500 fraud checks. Premium is a custom quote. No free plan is shown, the trial is by request, and only the Starter price is published. SEON's fraud check is the lookup you submit. It isn't an active identity, and it isn't a Sift contract. The longer comparison is Dregs vs SEON.

Castle

Who it's for: teams that need allow, challenge, or deny on the request in front of them, including account takeover enforced before a session exists.

Castle returns three scores on the request, Account Abuse, Account Takeover, and Bot, and a no-code policy engine can answer allow, challenge, or deny. Sift also covers account takeover, inside an enterprise platform whose center of gravity is the payment. Castle is the self-serve way to put that decision in the request path. Dregs detects account takeover from evidence on the account and raises a badge and an escalation. It doesn't return allow, challenge, or deny inside the request, and it doesn't block a login before the session exists.

As of October 1, 2026, Castle publishes a free tier ($5 of API usage: 1,000 Risk calls or 5,000 IP lookups, with 3 days of retention), a Pro plan at $200/month ($200 of API usage: 40,000 Risk calls or 200,000 IP lookups, with 7 days of retention), and Enterprise from $4,000/month with up to 18 months of retention. Risk calls are $0.005 and IP lookups are $0.001. The longer comparison is Dregs vs Castle.

Verisoul

Who it's for: gaming, SaaS, marketplaces, and market research fighting fake users, when a demo is an acceptable way to start.

Verisoul returns an account score of Real, Suspicious, or Fake, with boolean risk signals and linked accounts, and without a per-score explanation of why the model decided. FaceMatch, ID Check, and Phone Intelligence are add-ons with per-transaction pricing. Dregs doesn't collect identity documents. Choose Verisoul when you want those add-ons in the same product and a sales conversation is a fine way to start.

As of October 2, 2026, Verisoul's pricing page redirects to a demo booking form, and no free trial is advertised. As of October 1, 2026, the last published entry plan was Starter at $99/month for 1,000 monthly active users, dashboard only, with no API. Those figures are no longer a public price. The longer comparison is Dregs vs Verisoul.

ShieldLabs

Who it's for: web apps fighting multi-accounting, account sharing, account takeover, promo abuse, and free trial abuse, that want a score on the visit and will enforce it themselves.

ShieldLabs identifies one visit from device and network signals plus that visitor's history, and returns a 0 to 100 risk score (Trusted, Suspicious, or Dangerous) plus high-risk events with a confidence level. Your application chooses allow, challenge, or block. ShieldLabs never blocks anyone automatically. Dregs doesn't either. The difference is the unit: a visit, scored once, versus an identity that keeps being scored as further activity arrives. History is 90 days on every ShieldLabs plan, including Free.

As of November 2, 2026, Free is 5,000 identifications once, and further requests return HTTP 402 until you move to a paid plan. Starter is $99/month, or $79/month billed yearly, for 25,000 identifications. Growth is $399/month, or $319/month billed yearly, for 150,000. Scale is $999/month, or $799/month billed yearly, for 500,000, and Scale includes a 99.9% uptime SLA. Every plan treats the included volume as a hard cap. Further identification requests return HTTP 402, and there are no overage charges. Metering is per identification. Reading existing results through the History API doesn't consume that volume. The longer comparison is Dregs vs ShieldLabs.

Fingerprint

Who it's for: teams that want a stable visitor ID and will build decisioning, thresholds, and review in their own code.

Fingerprint returns a visitor ID and Smart Signals. It doesn't return an account verdict. Linking uses an ID your application supplies. That is the right Sift alternative when you wanted device intelligence as a component, including for jobs outside abuse, and the wrong one when you wanted someone else to decide. Dregs includes device fingerprinting on every plan as one signal among others. A visitor ID on its own is not proof of abuse. Shared devices create false positives when you treat them as one.

As of October 1, 2026, the free tier is 1,000 API calls a month, plus 500,000 Android API calls a month. Pro Plus starts at $99/month for 20,000 API calls, with the same Android allowance, and overage is $4 per additional 1,000 calls. Enterprise is custom. Metering is per API call. The longer comparison is Dregs vs Fingerprint.

IPQS

Who it's for: teams that want a per-lookup result on an IP, email, phone, or URL inside a pipeline they already operate.

One call scores one artifact. It doesn't follow the account afterward, which is the gap a Sift buyer hits after the transaction tools are in place and the junk is still in the user table. Device fingerprinting is an Enterprise feature. Dregs includes it on every plan and scores the identity. Choose IPQS for the lookup. Choose an account score when the lookup already came back clean and the signup is still a problem.

As of October 1, 2026, the free tier is 1,000 lookups a month, capped at 35 a day. Startup starts at $99/month for 5,000 lookups. SMB+ starts at $999/month for 75,000 lookups. Metering is per lookup, across the APIs. Enterprise is a custom quote. The longer comparison is Dregs vs IPQS.

When Sift Is Still the Right Product

Sift is the better choice when you are deciding whether to trust a transaction, at a volume where consortium data is the point. The published network is 34,000+ sites and more than a trillion events a year. Scores are ML risk scores from that network. Dregs doesn't process payments data and has no chargeback or dispute tooling. Card testing that shows up as throwaway accounts is still account abuse. Declining the card is Stripe Radar, Sift, or your processor.

Sift doesn't publish a price, and no free trial is advertised. As of October 1, 2026, there is no pricing page on sift.com. Contracts are annual and sales-led. Vendr reports a median around $150,000 a year, and a range of about $29,600 to $600,000 a year. Those numbers are third-party contract data, not a rate card. Getting started is a demo, then a sales and onboarding cycle. The full pair is Dregs vs Sift.

Where Dregs Is the Wrong Sift Alternative

  • Payment fraud, chargebacks, or dispute management is the loss. Stay with Sift, or use Stripe Radar or your processor. Dregs doesn't replace them.
  • You need AML, KYC, or a deep email and phone footprint. SEON is built for that.
  • You need allow, challenge, or deny before a session exists. Castle is built for that.
  • You want a 0 to 100 score on the visit, and your application will enforce it. ShieldLabs is built for that.
  • You want a visitor ID as a component. Fingerprint is built for that.
  • You want a lookup on an email, phone, IP, or URL. IPQS is built for that.
  • You want face matching or a document check in the same product. Verisoul's add-ons cover that. Dregs doesn't collect identity documents.

Frequently Asked Questions

Q: What are the best Sift alternatives for SaaS?

A: There isn't a single best Sift alternative. Match the tool to the job. Dregs is for SaaS signups and trials: fake accounts, duplicate accounts, and free trial abuse, with published pricing from $17 a month per active identity. It is an account-layer abuse prevention platform. It isn't a payment fraud or chargeback tool, and it doesn't replace Stripe Radar. SEON is for AML, KYC, and email or phone footprint work in fintech, payments, or iGaming. As of October 1, 2026, its published Starter plan is $699 a month. Castle is for an allow, challenge, or deny decision on the request itself. Verisoul is for fake users when you will book a demo. ShieldLabs is for a 0 to 100 score on one visit, which your application then allows, challenges, or blocks. Fingerprint is for a visitor ID you build a decision on. IPQS is for a lookup on one IP, email, phone, or URL. If the loss is the chargeback, Sift or your processor is still the better fit. Sift doesn't publish a price.

Q: What are Sift's competitors for a SaaS product?

A: For a SaaS product, the competitors that belong on the same shortlist are Dregs, Castle, Verisoul, ShieldLabs, Fingerprint, and IPQS. SEON belongs on it when you also need AML or a deep email and phone footprint, and you can start from a published $699 Starter plan instead of an annual enterprise contract. Sift remains the competitor to beat for enterprise payment fraud, chargebacks, and dispute management on a consortium-scale model. A chargeback platform, a visit score, and an account score are not three prices for the same thing.

Q: Is Dregs a good Sift alternative?

A: For enterprise payment fraud, no. Sift's consortium data and transaction decisioning operate at a scale Dregs doesn't attempt, and Dregs doesn't process payments or handle chargebacks. For fake users, free trial abuse, or duplicate accounts in a SaaS product, yes. Dregs addresses that problem on a published plan from $17 a month, billed per active identity, with a monthly checks allowance of 500,000 on Starter, 2,500,000 on Growth, and 5,000,000 on Advanced. A check is a score lookup for an identity you already track. Authenticity Check API calls count against the monthly operations quota. The trial is self-serve and needs no credit card. Dregs doesn't replace Stripe Radar. Catching a throwaway account earlier can still reduce the payment fraud that follows.

Q: When should you stay with Sift?

A: Stay with Sift when payment fraud, chargebacks, or dispute management is the core problem, or when you want account abuse and account takeover in the same enterprise platform as payment decisioning. Sift doesn't publish pricing. As of October 1, 2026, there is no pricing page on sift.com, contracts are annual and sales-led, and Vendr reports a median around $150,000 a year, with a reported range of about $29,600 to $600,000 a year. Those Vendr figures are third-party contract data, not Sift's official price. No free trial is advertised.

Q: How much do Sift alternatives cost?

A: Sift doesn't publish a price. As of October 1, 2026, Vendr reports a median contract around $150,000 a year. Dregs publishes every plan, starting at $17 a month for 100 active identities, then $177 a month for 5,000 identities and $377 a month for 10,000. Billing is per active identity. The monthly checks allowance is 500,000 on Starter, 2,500,000 on Growth, and 5,000,000 on Advanced. A check is a score lookup for an identity you already track. Authenticity Check API calls count against the monthly operations quota. As of October 1, 2026, SEON's published Starter plan is $699 a month, Castle's Pro plan is $200 a month, Fingerprint's Pro Plus plan starts at $99 a month, and IPQS paid plans start at $99 a month. As of November 2, 2026, ShieldLabs Starter is $99 a month, or $79 a month billed yearly, for 25,000 identifications. As of October 2, 2026, Verisoul doesn't publish pricing. A year of Sift and a month of account scoring are not the same purchase.
