  • Open Source
    Open DBDiff is open source, meaning it is free to use and can be modified to suit specific needs. This encourages community collaboration and improvements.
  • Cross-Platform

Possible disadvantages

  • Limited Database Support

  • Steeper Learning Curve
    Users unfamiliar with command line operations or lacking experience in database management might face challenges in using the tool efficiently.
  • Community-Based Support
    Being an open source project, support primarily comes from the developer community, which might not always offer the immediate assistance that a dedicated support team could provide.
  • Potential for Bugs
    As with many open source projects, there may be unresolved issues or bugs that can affect functionality, especially if the project isn't actively maintained.

Questions & Answers

As answered by people managing Open DBDiff and SellWhere.app.

Which are the primary technologies used for building your product?

SellWhere.app's answer:

  • Astro — static site framework for fast, SEO-friendly pages
  • React — interactive calculator components (Astro Islands architecture, so only calculators load JavaScript)
  • Tailwind CSS v4 — utility-first styling
  • Cloudflare Pages — global edge deployment for fast load times worldwide

What makes your product unique?

SellWhere.app's answer:

SellWhere is the only free tool that lets you enter a sale price once and instantly compare your net payout across 6 major resale platforms — eBay, Poshmark, Mercari, Vinted, Depop, and Etsy. Most fee calculators only handle one platform at a time.

Our eBay calculator goes deeper than any competitor, modeling 20+ item categories, 6 store subscription tiers, and 3 seller levels. Every calculator shows when fees were last verified, with direct links to official fee pages so you can trust the numbers.

How would you describe the primary audience of your product?

SellWhere.app's answer:

SellWhere serves two main groups:

  • Casual sellers clearing out closets or decluttering, who want to know which platform gives them the best payout before listing
  • Professional resellers who list across multiple platforms (eBay, Poshmark, Mercari, etc.) and need accurate, up-to-date fee comparisons to maximize their margins on every item

What's the story behind your product?

SellWhere.app's answer:

SellWhere was born from a real frustration: resale platform fees are confusing, constantly changing, and scattered across different help pages. We wanted one place to see exactly what you'd take home on every major platform, with no guesswork.

Resale fees are also in a period of rapid change — Mercari dropped its seller fee to 0% in 2024, Depop eliminated buyer fees in mid-2024, and Vinted launched in the US in January 2026. Keeping up is hard. SellWhere was built to be the single source of truth for resellers navigating these shifts.
