The verdict: can you vibe code Senja?
You can build a functional personal clone of Senja with a solid indie stack, but the video pipeline and third-party import connectors will take serious effort.
The core CRUD dashboard, collection forms, and embeddable widgets are straightforward to build with Next.js and Tailwind CSS. However, you will hit real friction when orchestrating reliable multi-megabyte video uploads, cloud transcoding, background transcription jobs via Whisper, and maintaining scrapers across 30+ external review platforms. For personal use, scoping down to native text/video collection and custom Walls of Love makes this a rewarding 2-to-3-week build; trying to replicate all 30 platform importers is a trap.
Estimated effort: 2-3 weeks part-time

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application with Tailwind CSS, configure better-auth, and set up the Neon Postgres database schema for users, projects, forms, and testimonials.
Scaffold a new Next.js project with TypeScript, Tailwind CSS, and App Router. Set up better-auth with email/password authentication linked to a Neon Postgres database using Drizzle ORM. Define database tables for `users`, `projects`, `forms` (storing collection parameters, questions, and custom branding settings), and `testimonials` (storing type [text/video], author name, email, avatar URL, rating, testimonial body, video storage URL, tags, sentiment status, and project ID). Ensure proper foreign key constraints and indexes on project_id and created_at. Verify the setup with a local migration test.02Testimonial Collection Forms & Public Submission
Build the public-facing submission page where clients can record video or write text testimonials.
Build a dynamic public collection form page in Next.js at `/collect/[formId]` that renders customer questions, branding accents, and collection toggles fetched from the database. Implement a dual collection mode: a text review textarea with star rating selection, and a browser-based video recording interface utilizing the MediaRecorder API with live camera preview and timer countdown. Implement secure direct-to-cloud upload logic for video blobs to Cloudflare R2 object storage. On successful submission, save the testimonial record to the database with a 'pending' status and show a customizable thank-you confirmation screen.03Dashboard Management, Tagging & Search
Create the main administrative dashboard for organizing, filtering, tagging, and managing collected testimonials.
Create a comprehensive dashboard view in Next.js at `/dashboard` that lists all collected testimonials in a data table and grid view. Implement server actions and UI controls for filtering testimonials by rating, type (text/video), and project, alongside a keyword search bar and custom tagging system. Add status toggles for pinning testimonials, archiving, or marking them as featured. Include a detail modal to preview video testimonials, edit author details, and assign custom metadata fields.04AI Transcription & Sentiment Analysis Pipeline
Integrate background processing jobs to transcribe video audio via OpenAI Whisper and analyze text sentiment.
Implement an asynchronous background processing route using Next.js API endpoints that triggers when a video testimonial is uploaded or a text review is submitted. For video files, download the audio stream, send it to the OpenAI Whisper API for transcription, and store the resulting text transcript in the database. Send both text reviews and video transcripts to the OpenAI API using structured JSON output to extract sentiment (positive, neutral, negative) and key product insights. Display these sentiment badges and transcripts directly inside the testimonial detail view in the dashboard.05Embeddable Widgets & Wall of Love Builder
Develop customizable embeddable widgets, carousels, and dedicated Walls of Love pages that users can deploy anywhere.
Build a widget builder interface at `/dashboard/widgets` allowing users to select layout styles (Grid, Carousel, Wall of Love), customize card colors, fonts, and badge visibility, and generate a snippet code. Create a lightweight, vanilla JavaScript script (`embed.js`) hosted on a public endpoint that fetches approved testimonials for a given project ID via a CORS-enabled API route and renders a responsive, high-performance widget DOM inside any third-party host website without layout shifts. Also build a standalone public page route at `/wall/[projectId]` that renders a full-page custom Wall of Love gallery.
