As answered by people managing Nullstack and Virlya.
Virlya's answer:
Most social media tools either schedule posts you have already made or help you design one graphic at a time. Virlya creates the content itself: it reads your website, researches your company, competitors and industry, and turns that into a campaign where posts build on each other. It works with your real product photos, writes separate captions for each network and makes short reels, and nothing goes live until you approve it.
Virlya's answer:
Choose Virlya if you don't have the time or a team to come up with content. Schedulers like Buffer or Hootsuite assume you already have posts; design tools like Canva assume you will make them. Virlya delivers ready-to-approve posts, carousels and reels in your brand colors, with a free plan to try the quality first. If you already have a content team and mainly need scheduling and reporting across many accounts, a dedicated management tool may suit you better.
Virlya's answer:
Small businesses and online shops without a marketing team: owners and small teams who know social media matters but can't spend hours every week on ideas, copywriting and design.
Virlya's answer:
Virlya started from work with small business clients as a web designer. After launching a website, the same question kept coming up: who will post on social media? Most owners didn't have the time or the budget for an agency, so their profiles stayed empty. We built Virlya to give them consistent, on-brand content they only need to review and approve.
Virlya's answer:
React, Node.js, Supabase (PostgreSQL), Redis job queues, Stripe for billing, and generative AI models for text, images, video and voice.
