Whatnot's dashboard shows estimates. Aftershows shows your real numbers.

Whatnot does $8B in GMV and their own help docs say not to use the native dashboard for taxes or any official reporting. Sellers end up doing fee math on notepads, dropping CSVs into spreadsheets, of paying a bookkeeper who doesn't understand live commerce.

Aftershows turns Whatnot's weekly Seller Hub CSV exports into the analytics sellers actually need.

What you get:

  • Profit per show after fees, shipping, refunds, and what you paid for inventory
  • Fee breakdown line by line (8% commission, 2.9% + $0.30 processing, refund handling)
  • Top buyers and lapsed buyer detection (who bought once and never came back)
  • Buyer cohort retention curves
  • Week-over-week, month-over-month, year-over-year trends
  • Boost ROI tracking (manual entry in v1)
  • Schedule C-ready CSV export at year-end with line-item mapping
  • Weekly Monday email summary
  • Surprising-insight engine that auto-flags outliers each week

Free tier: 2 uploads, single-week + week-over-week views. Paid tier: $19/mo unlimited or $180/yr (21% off). Unlocks multi-week trends, buyer cohorts, lapsed-buyer lists, Schedule C export, and the weekly email.

Built for serious Whatnot sellers earning $5K+/mo GMV who want real numbers instead of estimates. Card sellers, Pokemon and sports cards, sneakers, beauty, electronics, jewelry, fashion all supported.

Free standalone tools at aftershows.co/tools โ€” Whatnot fee calculator, profit calculator, and Schedule C calculator. No login required.

Independent product, not affiliated with Whatnot, Inc. We process the CSVs you export from Seller Hub. We do not store the original raw CSVs after parsing.

ThreadMine.dev features and specs

  • Specialized thread analysis
    ThreadMine.dev appears to focus specifically on analyzing threads (likely social media or forum threads), which allows it to offer more tailored insights compared to generic analytics tools.
  • Simple, focused interface
    The tool seems to have a clean, single-purpose interface centered around thread analysis, which can make it easy to use without unnecessary distractions or complex navigation.
  • Quick insights
    Purpose-built analysis tools like this often provide fast, digestible summaries or breakdowns of thread content, saving users time compared to manually reading through long threads.
  • Developer-friendly branding
    The '.dev' domain and naming convention suggest it may be built with developers or technical users in mind, potentially offering integrations or export options useful for technical workflows.
  • Niche utility
    For users who frequently need to parse or summarize long threads (e.g., research, social media monitoring), a dedicated tool can be more efficient than general-purpose alternatives.

Analysis of ThreadMine.dev

Overall verdict

  • ThreadMine.dev appears to be a niche tool aimed at helping users organize, save, or extract value from online threads (such as forum or social media discussions), though limited public information is available about it, so its quality should be judged based on a hands-on trial against your specific needs.

Why this product is good

  • May offer a simple, focused solution for a specific problem (thread management/curation)
  • Likely lower cost or complexity compared to enterprise-grade alternatives
  • Niche tools often iterate quickly based on user feedback since they're smaller projects
  • Domain name suggests a clear, specific value proposition around thread organization

Recommended for

  • Individuals who need to organize or archive online discussion threads
  • Content creators or researchers extracting insights from social media or forum threads
  • Users looking for a lightweight, specialized tool rather than a full-featured platform
  • Early adopters comfortable testing newer or smaller developer tools

Questions & Answers

As answered by people managing Aftershows and ThreadMine.dev.

What makes your product unique?

Aftershows's answer

Whatnot-only focus, analytics-first, real numbers instead of estimates. Whatnot's own help docs say their dashboard is estimates only and not for tax use. Aftershows processes the actual transaction CSVs and shows profit per show after fees, shipping, and what you paid for inventory. It also generates a Schedule C-ready CSV at year-end.

Why should a person choose your product over its competitors?

Aftershows's answer

Other reseller tools are multi-platform and bookkeeping-heavy. Seller Ledger covers eBay, Mercari, Whatnot, and others. Vendoo is for cross-listing. Aftershows does one platform deeply: live commerce on Whatnot. Per-show profit, fee transparency, buyer cohorts, and Schedule C export are built around the way Whatnot sellers actually work.

How would you describe the primary audience of your product?

Aftershows's answer

Active Whatnot sellers earning $5,000 or more per month in GMV. Card sellers, Pokemon and sports cards, sneakers, Funko, beauty, jewelry, fashion. Sellers who run weekly shows, want real numbers instead of Whatnot's estimates, and need a Schedule C export at tax time.

What's the story behind your product?

Aftershows's answer

Whatnot does $8B in GMV and tells sellers their own dashboard is estimates only. Reddit threads from r/whatnotapp showed sellers doing fee math on notepads, asking why their estimate said $74 but they got $66. Built Aftershows to give sellers real numbers, the way they already think about their business: per show, per buyer, per category.

Which are the primary technologies used for building your product?

Aftershows's answer

Next.js 16 (App Router), TypeScript, Tailwind v4, shadcn/ui, Recharts, Drizzle ORM, Postgres (Neon), Auth.js v5, Resend, Stripe, Vercel.
