PromptCraft Series #7 – Visual Prompt Design for No-Coders ✨ PromptCraft Series #7 "Visual Prompt Design for No-Coders" 🗕️ New post every Monday 🎨 Why Visual Prompt Design Matters Prompt engineering doesn’t have to be text-only or code-heavy. Today, powerful no-code tools allow you to design, trigger, and connect prompts visually using simple blocks, fields, and flows. Drag-and-drop interfaces reduce human error Inputs can be dynamically passed to prompt templates Output logic can be reused across different use cases Non-developers can build intelligent apps visually This blog explores how to do it right — with examples, templates, and real platform walkthroughs. 🔧 Anatomy of a Visual Prompt Block Component Purpose 🔢 Input Field Captures dynamic user input (text, image, number) 🧠 Prompt Template Combines static in...

The Tech Stack We Chose (And Why We Switched Midway) The Tech Stack We Chose (And Why We Switched Midway) By Rexman Published: 13/06/2025 – Behind the Scenes Series #2 🧠 The Master Plan Choosing a tech stack was easy. Or so we thought. We had a Notion page comparing Postgres vs Mongo, Firebase vs Supabase, React vs Vue vs SvelteKit. We were acting like we were choosing our life partner — when really, we just needed a stack that wouldn’t break in 3 weeks. We picked: Frontend: React Native with Expo Backend: Supabase (Postgres + Auth) Storage: Supabase Storage AI integration: Claude (Anthropic) Deployment: Vercel 💥 Reality Bites Week 1 was smooth. By Week 2, cracks appeared. Supabase’s Postgres was fine… until our expensive queries choked it. React Native was okay, but we hit prop-passing hell fast. Claude integration was awesome… until we realized we needed more dynamic prompt chaining a...

From 24 wishlist features, we cut 18. From 3 user personas, we chose 1. Our only goal was to solve one job well . Signup → Get value Log back in Share it with someone else No dashboards. No settings. No custom flows. Just the job. Week 2: Setup ...
