Going viral on X? Protect your free tier before launch day
Launching your SaaS on X? A viral launch brings real users and a wave of duplicate accounts. How indie hackers protect free credits and trials before launch day.
Launching on X has become the indie hacker's rite of passage. You build in public for weeks, post the demo video, write the launch thread, and hit post. If it takes off, thousands of people see your product in a day. It's one of the best things that can happen to a new SaaS.
It's also the moment your free tier is most exposed. Everyone sees the launch at once, including the people who collect free credits for a living, and the scripts they run don't need an invitation.
From our early beta
After a launch went viral on X, one team gained 6,400 new users in a month. 2,700 of them were duplicate accounts. About 32 became paying customers.
That's what a successful launch can look like without protection: a huge sign-up number, a tiny customer number, and a bill for everything in between.
Why a viral launch attracts abuse
- You broadcast the offer. "500 free credits for everyone who signs up today" is a great hook. It reaches farmers as fast as it reaches customers.
- It all happens at once. Abuse that would trickle in over months arrives in hours, often while you're asleep after the launch.
- Replies and quote posts spread it further. Every share is another audience, and some of them only want the free part.
- You have no history yet. On launch day, nothing in your app knows who already claimed. Every new email looks like a new person.
What a launch day can turn into
The bill is only part of it. When fake accounts eat your AI quota, real users from the launch hit errors on the most important day your product will ever have. First impressions don't get a second launch.
Protect your launch in an afternoon
Create a benefit for each launch offer. Free credits, the trial and any launch promo code each become an AbuseZero benefit, claimable once per user.
Pick Strict for anything expensive. Free AI credits are spent the moment they're granted. Give them the Strict protection level.
Add one call before every grant. Your server asks AbuseZero before granting the credits or starting the trial, and gets allow or deny back. See add a trial and credit abuse check to your signup flow.
Test it on pre-launch traffic. Run in observe mode during your beta or waitlist period, check what AbuseZero would deny, then switch to protect before the launch post goes live.
Set up a launch-night alert. Send denied evaluations to your phone or team chat with a webhook, so you see a wave starting instead of reading about it in the morning. See AbuseZero webhooks.

Launch with protection
Builder is made for MVPs and lightweight apps: pay as you go, no subscription, protection from your first claim. Start with Builder or see pricing.
Launch offers that stay generous
You don't have to give less to stay safe. Protection is what lets you keep the offer generous:
- Size credits to the "wow" moment, not to a month of use. See how to protect signup credits in an AI app.
- Make launch codes once per person, checked before they're applied. See how to stop promo code and referral abuse.
- Let real AI agents in. Some of your launch users will sign up through assistants. See AI agents are claiming your free trials.
Already launched? It's not too late
If your launch already happened, import the credits and trials you've granted so AbuseZero knows who already received them, then turn protection on. The next wave meets a check that knows your history.
Frequently asked questions
Should I give free credits in my launch post?
Free credits are one of the best launch hooks. Just check every claim before you grant them, so one person can't collect them through dozens of accounts.
How do I stop duplicate accounts after a viral launch?
Evaluate each claim on your free credits, trial or free plan before granting it. AbuseZero checks every claim against everyone who already received the benefit, across new emails, devices and networks.
Is it too late to add protection after launch?
No. Import the benefits you've already granted, so protection starts with your history, then turn it on for every new claim.
Do I need to be technical to set this up?
It helps, but an AI coding agent can do most of it through the AbuseZero MCP server. See AbuseZero MCP server and CLI.
