Questions & Answers

As answered by people managing Walls.io and PostCSS.

What makes your product unique?

Walls.io's answer

Walls.io is a flexible, enterprise-ready social wall platform that helps brands collect, moderate, and display social media content and direct user submissions in real time—across websites, events, apps, intranets, and digital signage.

What truly sets Walls.io apart is its combination of ease of use, deep moderation control, and privacy-first design. With features like Direct Posts (no social account required), GDPR-friendly moderation workflows, and broad integrations (event platforms, CMSs, digital signage tools), Walls.io works just as well for public campaigns as it does for internal communications and regulated industries.

Why should a person choose your product over its competitors?

Walls.io's answer

People choose Walls.io when they need reliable engagement without risk. Compared to competitors, Walls.io offers:

  • Direct Posts with QR codes, enabling safe participation without forcing users onto social networks

  • Advanced moderation and approval flows, ideal for large screens, internal comms, and conservative industries

  • True omnichannel flexibility: one wall can live on a website, at a live event, inside an app, and on office screens

  • Strong compliance posture, supporting GDPR-conscious brands and global organizations

In short, Walls.io isn’t just about displaying social media, it’s about owning and controlling the experience while still feeling live and authentic.

What's the story behind your product?

Walls.io's answer

Walls.io was founded in Austria with the goal of making social media content usable beyond native platforms, especially at events and on owned channels.

Early on, the team recognized a gap: brands wanted the energy of social media, but not the chaos, data risks, or platform dependency.

It has since grown into a global solution used by enterprises, NGOs, universities, and major brands worldwide.

  • Introducing Fylgja CSS Attr v2 Polyfill
    Second, it has to be easy to integrate into a project, so we needed integrations with the popular CSS compilers. That means support for ViteJS, LightningCSS and PostCSS. - Source: dev.to / about 2 months ago
  • The tech stack behind InkRows
    Tailwind CSS keeps styling consistent and fast. The utility-first approach means I don't waste time naming classes or managing CSS organization. With the Vite integration and PostCSS transformations, the build stays lean. - Source: dev.to / 10 months ago
  • Desktop apps for Windows XP in 2025
    Fortunately we have tools like PostCSS and Babel, that let you target your specific Browser version, and they'll do their best to transpile and polyfill your code to work with that version. This alone will do a lot of the heavy lifting... - Source: dev.to / over 1 year ago
