The verdict: can you vibe code Loom?
Build a personal subset for your own video library using Next.js and Mux, but pay for Loom if you rely on its team distribution loop.
Replicating Loom's client-side recording and playback loop as a solo developer is achievable using modern web browser capture APIs, Mux for video streaming, and OpenAI for transcripts. However, building the entire native cross-platform recording suite, robust enterprise permissions, and deep Atlassian ecosystem integrations requires months of unglamorous engineering. A personal clone centered around web-based recording and AI summaries is a rewarding side project, but maintaining video delivery at scale makes paying for the real product rational.
Estimated effort: 2-4 weeks part-time
What you can't replicate
- The massive viral loop of millions of external users viewing shared link domains
- Enterprise compliance frameworks, SAML SSO, and Atlassian Guard security tiers
- Native system-level audio capture and background noise suppression across macOS and Windows

Build guide
01Project Scaffolding and Database Schema
Initialize a Next.js project with Tailwind CSS, configure Turso database connectivity, and implement better-auth for user authentication.
Initialize a new Next.js project using TypeScript and Tailwind CSS. Configure better-auth with email/password authentication backed by a Turso SQLite database using the libSQL client. Create database migration schemas for users, workspaces, videos (storing video ID, title, transcript, summary, duration, and author ID), comments, and reactions. Set up proper environment variable validation and clean project directory structures.02Screen & Camera Recording Interface
Build the web-based screen and webcam recording component using browser MediaRecorder APIs.
Build a React recording component that captures screen video via getDisplayMedia and webcam/audio via getUserMedia. Allow users to overlay a floating draggable webcam bubble onto the screen recording canvas. Implement start, pause, resume, and stop controls. Record the stream into webm chunks, assemble them into a Blob upon completion, and display a local video preview player with download options.03Video Upload and Mux Streaming Pipeline
Integrate Mux video upload and streaming services to handle processed video hosting and playback.
Integrate Mux video upload API into the Next.js backend. Create a server action to generate direct upload URLs from Mux so the frontend can securely upload recorded video blobs directly to Mux storage. Save the resulting Mux asset ID and playback ID in the Turso database linked to the user's video record. Implement a responsive video player component using Mux Player to render uploaded recordings smoothly.04AI Transcription and Summary Pipeline
Implement automated audio extraction, OpenAI Whisper transcription, and GPT summary generation.
Create a background job or server action triggered after a video upload finishes. Download the audio track or send the video asset to the OpenAI Whisper API to generate a precise timestamped transcript. Pass the resulting transcript text to the OpenAI GPT-4o API using structured outputs to automatically generate an engaging title, a concise summary, chapter breakdowns with timestamps, and an extracted list of action items/tasks. Store these results in the video record.05Video Watch Page and Interactive Elements
Build the public video watch page featuring synchronized transcripts, comments, and emoji reactions.
Build a video watch page route (/watch/[id]) with a split layout: the Mux video player and AI summary/chapters on the left, and a scrollable synchronized transcript on the right clicking which seeks the video. Implement a comment thread component with timestamp anchors linked to the video playback time, and an emoji reaction bar that saves interactions to Turso with real-time state updates.06Workspace Library and Sharing Dashboard
Create the user dashboard for organizing, archiving, and sharing video libraries.
Build a user dashboard workspace interface displaying personal and shared video libraries in grid and list views. Include search and filtering by title, folder organization, and privacy controls (public link vs password-protected). Implement a share modal that copies the public watch link and provides embed code snippets for external tools.
