The Best Whatnot Bot to Grow Followers, Relist & Sell on Autopilot

A Whatnot bot is an automation tool that grows your audience and keeps your listings fresh: following active buyers, following back new followers, unfollowing non-reciprocal accounts, and relisting aged items, so your Whatnot shop keeps building momentum around the clock.

Whatnot is a live-selling marketplace. Your followers get notified when you go live, so your following is the audience that actually shows up to bid and buy. Building that audience by hand, and relisting your marketplace items every day, is impossible to keep up with.

Sidekick Tools is a cloud-based bot for Whatnot that does it for you. It runs on our servers with natural, human-like pacing, so your Whatnot shop keeps growing even when you’re offline, at your day job, or prepping your next show.

Most tools do one thing. The best Whatnot bot does everything a live seller needs in one place: auto follow, follow back, auto unfollow, relisting, and crosslisting to 7 marketplaces, with safety controls built in.

Grows your audience

Auto follow, follow back and auto unfollow build the following that shows up to your live shows, on autopilot.

Safety built in

Human-like pacing, daily limits and schedules keep your follows and relists inside natural ranges, not robotic bursts.

Runs 24/7 in the cloud

It keeps working between shows, while you sleep, or out sourcing, so your Whatnot momentum never stalls.

Auto Follow, Follow Back & Auto Unfollow

The follow bot grows the audience that powers your live shows. It follows active buyers so more people get notified when you go live, follows back new followers to keep them engaged, and unfollows non-reciprocal accounts to keep your ratio healthy.

• Auto Follow active buyers to expand your reach
• Follow Back everyone who follows your shop
• Auto Unfollow to protect your follow ratio

Auto Relist: Keep Aged Listings Selling

Your Whatnot marketplace listings get buried as new items are added. The relist bot reposts eligible aged items automatically so they resurface for buyers, with rules you control, and it can skip items that already have bookmarks so you keep buyer interest.

• Only relists aged items (minimum listing age of 15, 30 or 60 days)
• Staggers relists with a daily limit and a time-slot schedule
• Skips items with bookmarks so you never lose buyer interest

Cross Post Whatnot to 7 Marketplaces

Your inventory shouldn’t be stuck on one app. Cross Post your Whatnot items to Poshmark, eBay, Mercari, Depop, Etsy, and Grailed in a few taps, then auto-delist when something sells so you never oversell.

• List once, sell across 7 marketplaces
• Auto-delist sold items to avoid double sales
• AI stock photos and a background remover included

Whatnot’s terms discourage aggressive automation, so account safety comes down to one thing: behaving like a human. That’s exactly how Sidekick Tools is engineered.

Human-like pacing

Follows, follow backs and relists run at natural intervals, so your activity looks like a real person, not a bot.

Daily limits and schedules

Cap how much runs per day and choose a time slot, so your activity stays inside safe, natural ranges.

Healthy ratios

Auto unfollow keeps your follow-to-following ratio balanced, so your growth looks organic as you scale.

No tool can promise zero risk, but safe, natural behavior is what protects your account, and it’s built into everything Sidekick Tools does. See the FAQ below for direct answers on bans, legality, and Whatnot’s policy.
