What is Screen Script

Screen Script is a fast, modern, browser-based screen recorder built to help creators, developers, and founders capture clean, high-quality videos without heavy software or complex setup. It focuses on simplicity, speed, and clarity — offering smooth recording, instant exports, and a distraction-free workflow. Whether it’s a product demo, UI walkthrough, coding tutorial, or pitch video, Screen Script makes recording effortless.

Why I Started It

Screen Script began during a hackathon at KPH KPH hackathon. I wanted to build something simple yet useful — a tool that solves a real day-to-day problem: capturing clean screen recordings without lag, noise, or bloated apps.

During the hackathon, I noticed something interesting: "people were genuinely excited about this idea".

Participants tried it, shared feedback, asked for features, and even discussed real-world use cases like demo videos, tutorials, and startup product launches. That validation made me realize Screen Script had potential beyond the event.

So I continued building it after the hackathon — improving UI, tuning performance, experimenting with encoding methods, and polishing the entire workflow. What started as a 48-hour build gradually grew into a full product with real users and real use cases.

Technical Overview

Screen Script is built with a modern, scalable, and performance-focused stack:

Framework & Platform

  • Next.js for routing, fast builds, and SEO
  • React.js for the UI
  • Supabase for authentication, storage, and backend logic
  • PostHog for analytics, user flows, and product insights

Deep Tech & Engineering

Screen recording is not just “capture screen → save file.” To get smooth, minimal-lag videos, Screen Script handles several complex layers:

  • MediaRecorder API for native browser-level video capture
  • Real-time WebM encoding optimized for clarity and consistent framerate
  • Buffer stream management to avoid dropped frames during motion
  • Efficient memory handling for long-duration recordings
  • Instant video assembly pipelines for quick download after stopping

Experimental modules exploring:

  • MJPEG streaming
  • Frame-by-frame rendering
  • Device-to-web capture
  • Browser-based video post-processing

Every layer is designed to reduce friction for the user while keeping the output clean and stable.

What I Learned (Being the Real Founder of This Project)

Screen Script taught me more than just tech.

Building this as a solo founder — handling content creation, engineering, UI/UX, SEO, branding, and sales — gave me a full 360° view of what building a product truly takes.

Some of the strongest learnings:

  • Understanding how users think, not just how systems work
  • Designing for clarity instead of complexity
  • Shipping fast, iterating faster
  • Balancing engineering depth with practical product decisions
  • Doing everything myself showed me my skills, limits, and strengths
  • Developing empathy for creators, marketers, and founders
  • Realizing that every small detail — from landing page text to loading speed — affects conversions

This project made me both a better engineer and a better entrepreneur.

What Makes Screen Script Special

  • Starts instantly — no installation, no setup
  • Crisp recordings even on mid-range systems
  • Supports long, high-motion captures
  • Zero clutter interface
  • Built for real-world startup demos and tutorials
  • Continually shaped by user feedback and real use cases

The Future

Screen Script will keep evolving. Upcoming ideas include:

  • Desktop application
  • Mobile & Android capture utilities
  • Cloud saving
  • Auto-editing for short clips
  • Better noise-free recording pipelines
  • Collaboration tools for teams
