Questions & Answers

As answered by people managing VS Code and FlexinaTools.

How would you describe the primary audience of your product?

FlexinaTools's answer:

  • Small business owners, accountants and freelancers who deal with e-invoicing (Peppol, VAT, invoice generation) in the EU โ€” especially Belgium, France, the Netherlands, Germany, Spain and Portugal
  • Developers and technical users who need quick utilities: JWT decoding, Base64, JSON/XML formatting, hashing
  • Everyday users who want fast, private PDF and image tools without creating an account
  • Home-project planners who use the calculators (tiling, paint, insulation, mortgage)

What makes your product unique?

FlexinaTools's answer:

FlexinaTools is a privacy-first platform: all 46 tools run 100% in your browser, so your files and data are never uploaded to a server and no account is required. It goes beyond generic PDF utilities to cover niche professional needs โ€” Peppol BIS 3.0 e-invoice validation, VAT calculation for 7 EU countries, IBAN validation โ€” and the whole interface is localized in 6 languages (English, French, German, Spanish, Portuguese, Dutch).

Why should a person choose your product over its competitors?

FlexinaTools's answer:

Most online tool sites charge or rate-limit the same operations. With FlexinaTools, all 46 tools are completely free, with no sign-up, no paywall and no usage limits โ€” because everything runs in your own browser, we simply don't pay for server-side processing. On top of privacy (your invoices, PDFs and images never leave your device), it bundles things competitors don't have: a Peppol BIS 3.0.3 e-invoice validator, a multi-country VAT calculator and a full PDF + image + developer toolkit in one place.

What's the story behind your product?

FlexinaTools's answer:

FlexinaTools was built by Flexina SRL, a software company based in Liรจge, Belgium. It started as a collection of small utilities the team kept using internally โ€” invoice generation, VAT calculations, PDF merging โ€” and it grew when we noticed that people always ask for the same things: a quick tool, no account, and the guarantee that their files never leave their device. The guiding principle became: if the browser can do it, the server should never see it. Today the site groups 46 free tools around four universes โ€” business, documents, home projects and developer โ€” and is localized in 6 European languages.

Which are the primary technologies used for building your product?

FlexinaTools's answer:

  • Vue 3 single-page application with vue-router
  • Vite + vite-ssg: every page is statically generated at build time for fast loading and good SEO, in 6 locales
  • Client-side JavaScript libraries: pdf-lib and pdf.js for PDF operations, Aspose for advanced PDF processing, Canvas API for image tools
  • All computation runs in the visitor's browser โ€” the site itself is a static site with no application backend

Who are some of the biggest customers of your product?

FlexinaTools's answer:

  • FlexinaTools is a free, self-serve product, so it has no named corporate customers to list
  • Its daily users are individuals, freelancers and small businesses across the EU who validate Peppol e-invoices, merge PDFs or calculate VAT
  • The product is developed and operated by Flexina SRL, a software company based in Liรจge, Belgium

Choosing the Best SQL Server Tool in 2026
If you're a Windows DBA who mainly manages servers, SSMS is still hard to beat. SQL Server Data Tools makes the most sense for teams building database projects in Visual Studio, Visual Studio Code with the MSSQL extension is a good option for cross-platform development, and DBeaver works well if SQL Server is just one of several databases you manage.

    For IDE-heavy teams, BYOK (bring your own key) can be interesting, no matter whether you live in WebStorm or VS Code. On the JetBrains side, the JetBrains AI plans and Junie BYOK docs allow it, and most VS Code AI extensions offer the same idea: keep the IDE, connect provider keys, pay the provider. - Source: dev.to / 3 months ago
  • Best Markdown Editors for Developers
    Option 1: Raw editing in IDE. You open the .md file in VS Code or whatever you use. Syntax highlighting shows you the structure. Maybe you toggle a preview pane. This works for quick edits but becomes painful for anything involving tables, diagrams, or complex formatting. - Source: dev.to / 3 months ago

    You'll need Python 3.8+ and pip for the quickstart, with venv recommended for isolation. Install the requests library for HTTP calls. VS Code with the Python extension works well as an editor, though PyCharm or Sublime Text work equally well. You'll also need a free Foxit developer account. - Source: dev.to / 3 months ago
