What are the best free trial abuse prevention tools?

1Capture logoThe short answer

1Capture is the best free trial abuse prevention tool for SaaS teams that bill through Stripe, because it puts a card in front of every trial and matches each signup to dispute history shared across merchants, so a new email address no longer gets a new free trial. The other seven tools below cover bots, devices, email and phone risk, and account scoring: Stripe Radar, Fingerprint, SEON, DataCops, Sift, Cloudflare Turnstile and hCaptcha.

Here are all eight tools side by side.

Units differ1Capture is free below $10K MRR

Each tool guards a different step of the signup.

A bot check on the form cannot see the device behind it, and a device ID cannot see the card, so the tools stack rather than replace each other.

  1. 1

    The form

    Is this a bot?

  2. 2

    The device

    Has this device signed up before?

  3. 3

    Email, phone and IP

    Does this person look real?

  4. 4

    The account

    Is this a known bad account?

  5. 5

    The payment method

    Is there a card behind the trial?

1Capture logo

Is 1Capture the right tool to stop repeat free trials on Stripe?

Yes, when the abuse is the same person signing up again with a new email address. 1Capture puts a card in front of every trial and matches each signup to dispute history shared across merchants, so a throwaway email no longer gets a free trial. It is free under $10K MRR and then $95 to $1,995 a month, and it is built for Stripe accounts.

How a trial starts with 1Capture

  1. 1

    The visitor opens your trial page

    It is a hosted trial page built from your Stripe product.

  2. 2

    A card goes on file

    The trial does not start until a card is in place.

  3. 3

    The trial runs in your Stripe

    Everything lives in your own Stripe account.

  4. 4

    Payment lands when the trial ends

    It is collected in the last 2 hours of the trial, so a cancellation before that costs nothing.

Stripe Radar logo

Does Stripe Radar stop free trial abuse?

Yes, but only on its Pro tier. Radar lists free trial abuse and multi-account protection under Pro, with plans starting at $20 a month and a pay-as-you-go option. It is built into Stripe, so it suits teams that want one vendor for payments and screening.

Fingerprint logo

Can Fingerprint stop people signing up for a free trial again?

Yes, if your engineers act on the signal. Fingerprint gives each device a visitor ID that stays the same when cookies or the IP address change, and your code decides what happens when the same ID signs up again. The free plan covers 1,000 calls a month, and Pro Plus starts at $99 for 20,000.

SEON logo

Does SEON catch free trial abuse with email and phone checks?

It catches the multi-accounting behind it. SEON scores an email address, phone number and IP for throwaway signals and links accounts that share a device. The cheapest published plan is $699 a month for 2,500 checks, and its signup pages talk about multi-accounting and bonus abuse rather than free trials by name.

DataCops logo

Does DataCops stop free trial abuse?

Partly. Its SignupCops feature profiles each signup for email risk, IP type and linked accounts on the same device, and keeps risky signups out of your ad platforms. Basic is free, Business is $49 a month and Organization is $299 a month, billed annually.

Sift logo

Is Sift a good fit for free trial abuse?

It covers it, but you will need a sales conversation to price it. Sift lists signup abuse, fake accounts and trial abuse among what it detects, and its site shows a demo button instead of a price.

Cloudflare Turnstile logo

Is Cloudflare Turnstile enough to stop free trial abuse?

No, it stops bots and not people. Turnstile is a free CAPTCHA replacement with no cap on verifications, 20 widgets per account and 10 hostnames per widget. Pair it with a tool that remembers who already had a trial.

hCaptcha logo

Is hCaptcha enough to stop free trial abuse?

No, for the same reason as Turnstile: it tests whether a visitor is a bot, not whether this person already had a trial. Free is $0, Pro is $99 a month billed annually or $139 billed monthly with 100K evaluations included, and Enterprise is by quote. Use it to keep scripts off your signup form.

Pick the tool that matches how the abuse reaches you.

These are the questions teams ask before they pick a tool.

What is free trial abuse?

Free trial abuse is one person using a free trial again and again, usually with a new email address or a new account each time, without ever intending to pay. It costs real money when the product has per-user costs such as compute, credits or support time.

What is the cheapest way to stop free trial abuse?

Cloudflare Turnstile is free for blocking bots, and 1Capture is free under $10K MRR for stopping repeat trials on Stripe. Fingerprint, DataCops and hCaptcha also have free tiers with usage limits.

Do I need more than one tool?

Often yes. A bot check such as Turnstile or hCaptcha protects the form, and a second tool deals with real people who come back: a device ID, email and phone scoring, or a card at signup.

Will asking for a card at signup hurt my trial signups?

Some visitors will not add a card, and the ones who do are more likely to become customers. You can measure it yourself by running one group with a card and one without, then keeping the one that earns more.

Does 1Capture charge the customer during the trial?

No. The customer is not charged during the trial. Payment is collected in the last 2 hours of the trial, and a cancellation before then means nothing is collected.

How were these eight tools chosen?

Together they cover every step of a signup: the form, the device, the email and phone, the account history and the payment method. Each price on this page comes from the tool's own pricing page, and the links are listed at the foot of the page.

Every price on this page comes from the tool's own site.
