I’m Chandan Karn, co-founder of Postflare AI, an AI-powered SaaS that helps creators and professionals automate their social media presence on LinkedIn and Twitter. My co-founder Nitesh Gupta and I are both experienced engineers with full-time jobs, and we built this as a bootstrapped side project to solve a challenge we both faced: consistently managing social content while juggling busy schedules.
Building a meaningful social media presence takes time and effort—finding topics, writing posts, creating visuals, and scheduling them can be overwhelming. Postflare AI automates this workflow by generating content and images using advanced AI (Claude, Gemini, GPT-5) and scheduling posts in bulk, so users can maintain regular engagement without spending hours each week.
Technical Story (Bootstrapped and Lean): Instead of expensive cloud providers like AWS ($300+/month for Kubernetes), we opted for Hetzner Cloud’s affordable offering. We self-manage a Kubernetes cluster with 3 VMs running Next.js frontend, Supabase backend, and AI integration for under $60/month. This lean architecture allows us to scale multiple SaaS apps cost-effectively.
What Postflare AI Does:
AI Content Co-pilot: Generates a week or month of tailored posts and research based on your niche
AI Image Generation: Creates custom visuals within the platform, no external tools needed
Bulk Scheduling: Queue posts in advance to keep your social presence steady
We’re in early stages and eager for feedback. You can sign up and try it out here: https://postflareai.com — no credit card required to start.
I’d love to hear from the community: What were unexpected technical challenges you faced building your first lean SaaS? Have you experimented with low-cost cloud infra or Kubernetes alternatives?
Thanks, Chandan Karn (with Nitesh Gupta) Co-founders, Techxeni LLC
