Thunderclap review: we used it for 30 days

What is Thunderclap?

Thunderclap is an online store for Instagram, TikTok and YouTube engagement. On Instagram it sells followers, likes, views, story views and comments, plus automatic likes and a monthly follower subscription it calls a growth service.

Despite the name, that growth service doesn't help people discover you. It's a recurring order of followers, so it works nothing like the Instagram growth tools we recommend.

How Thunderclap works

Thunderclap doesn't promote your profile to anyone. It adds followers to your account in batches, spread over hours so the jump looks less sudden. The subscription repeats that every month until you cancel.

Step 1: Pick a package or plan

Choose a one-off follower package, or a monthly subscription that sends a fixed number of followers every month.

Step 2: Add your profile

Enter the username or link. No password is requested.

Step 3: Followers are drip-fed

Orders usually begin within half an hour and trickle in over several hours.

Step 4: Repeat each month

On a subscription, a new batch arrives every month until you cancel.

Step 5: 30-day refills

If the count drops within 30 days, Thunderclap refills it at no cost.

Who is Thunderclap best for?

Thunderclap sells followers two ways: as one-off packages, or as a subscription that drops a set number onto your profile every month. Either way you're buying a number. Our test showed what that number is worth.

A good fit if you

• Want a follower count that rises every month
• Are happy paying for numbers, not people
• Need a quick bump on a post or profile
• Don't plan to rely on Instagram for sales

Skip it if you

• Want people who engage with your content
• Care about your engagement rate and reach
• Want a refund if you're simply unhappy
• Are building a brand that partners will check

Why use Thunderclap at all?

The appeal is speed and price. A few dollars buys a visible jump in followers, and the subscription keeps the number climbing without any effort on your part.

But a follower count only helps when the people behind it engage. When engagement falls this sharply, fewer of your followers ever see each post, which is the opposite of what most buyers want. Our guide to building real followers covers what moves the needle instead.

We saw the same thing with other follower shops. Our Views4You review found another big jump in numbers that came with a collapse in engagement.

Even services that talk about AI targeting can end up in the same place, as our test of RiseKarma showed.

If you want growth that comes from real people in your niche, Flock Social's service is one of the options we'd actually recommend.

How we tested it

Thunderclap delivered to one of our test profiles during a 30-day run across September and October 2026; it had 1,617 followers on day one. Posting carried on as normal, with no other changes.

Instagram Insights gave us start and end figures for followers, engagement and month-long reach. Then we stopped ordering and, 14 days on, counted the followers that had disappeared.

What we liked

No password needed

Thunderclap only needs a username or link, never your Instagram password.

Quick to start

Orders start quickly and support is available around the clock by chat and email.

What we didn't like

It delivered bot followers

Our test account grew from 1,617 to 8,783 followers, while engagement collapsed from 3.1% to 0.4%. Reach barely changed, and 311 had unfollowed within a fortnight of our last order. A wave of silent followers that later melts away is the signature of bot accounts.

A subscription to bought numbers

The growth subscription is a monthly follower delivery, from $1.99 for 100 followers a month up to $76.99 for 10,000. It's still buying followers, just on repeat.

Refunds only for non-delivery

Refunds are offered if Thunderclap fails to deliver. If followers arrive and then leave, you get a free top-up within 30 days instead, not your money back.

Mixed customer reviews

Its Trustpilot score is 3.6 from 47 reviews, and recent critical reviews describe orders that never arrived and followers that dropped away after delivery.

Thunderclap pricing

The monthly subscription delivers a set number of followers each month; Premium followers cost a little more than High Quality. Annual billing is cheaper, but the prices above are monthly.

Every order includes a 30-day refill. Refunds can be requested within 30 days, mainly if an order isn't delivered.

Prices checked October 15, 2026.

Is Thunderclap safe?

Thunderclap doesn't need your login, which keeps your account itself out of reach. But paying for followers sits outside Instagram's community terms, and a crowd of accounts that never engage is what Instagram's periodic clean-ups target.

That means the main risk isn't a hacked account, it's a profile whose numbers look inflated and whose posts reach fewer real people because so few followers react.

Thunderclap review: our verdict

Thunderclap is cheap, fast and password-free, but what it delivered behaved like bots: thousands of new followers, an engagement rate that fell to 0.4% and hundreds lost soon after we stopped. A monthly subscription only repeats the problem. For followers who actually care about your posts, pick from the best growth services on our ranked list.
