AI session replay that catches issues before your users do

The verdict: can you vibe code LogRocket?
Build a thin personal error and event log viewer, but keep paying for LogRocket if you need production-grade session replay at scale. The single biggest catch is writing a performant DOM mutation recorder that doesn't tank host application performance.
LogRocket is an industrial-strength observability and session replay platform backed by years of low-level client recording engineering and high-throughput columnar data ingestion pipelines. While AI coding tools can scaffold a Next.js dashboard, a basic SQLite database, and an OpenAI error summarizer in a few days, writing a robust client-side `MutationObserver` recorder that handles shadow DOMs, iFrames, and dynamic stylesheets safely without leaking PII or freezing user browsers is a grueling systems engineering challenge. Replicating even a fraction of their web and mobile SDK performance makes this a serious multi-week or multi-month undertaking.
Estimated effort: 3-6 weeks of intensive development
What you can't replicate
- Optimized, production-tested client recording SDKs for every web and mobile framework
- High-throughput columnar ingestion infrastructure capable of handling millions of DOM event payloads

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js project with Tailwind CSS and configure Turso with better-auth and Drizzle ORM.
Create a new Next.js project configured with TypeScript, Tailwind CSS, and App Router. Set up Turso database connection using Drizzle ORM with tables for 'projects', 'sessions', 'events' (storing JSON event payloads), 'errors' (storing stack traces and error metadata), and 'metrics'. Configure better-auth for single-user dashboard authentication. Build a clean dark-mode dashboard layout with sidebar navigation for Dashboard, Sessions, Errors, and Analytics.02Client-Side Recorder SDK
Build a lightweight client-side JavaScript SDK that captures DOM mutations, console logs, and network requests.
Create a client-side recorder script package in the repository. Implement a DOM traversal and MutationObserver that serializes initial DOM state into snapshot nodes and captures subsequent mutation records. Instrument window.console.error and patch global window.fetch and XMLHttpRequest to intercept network requests, response statuses, and durations. Batch these captured events locally and flush them periodically via navigator.sendBeacon or fetch POST to an ingestion endpoint.03Ingestion Pipeline API
Implement high-performance backend API routes to ingest, validate, and store raw session telemetry batches.
Create a POST API route /api/ingest in Next.js that accepts batch telemetry payloads from the client SDK. Validate the project API key header, parse the compressed array of DOM mutations, console logs, and network events, and efficiently batch-insert them into the Turso database tables with proper indexing for fast retrieval by session ID.04Session Replay Player Dashboard
Build an interactive session replay player interface featuring a timeline scrubber and event inspector.
Build a session replay viewer page at /sessions/[id]. Fetch the stored DOM snapshots and chronological mutation events for the session. Create a custom React canvas or sandboxed iframe player that reconstructs and plays back DOM state updates dynamically along a timeline scrubber. Below or beside the video canvas, add synchronized tabs displaying Console Logs, Network Requests, and JavaScript Errors that highlight at the exact timestamp when they occurred during the session.05Error Tracking and Galileo AI Summaries
Implement error grouping, stack trace inspection, and AI-powered session and error summaries using the Anthropic API.
Build an Errors dashboard listing captured client-side exceptions and failed network requests with occurrence counts and affected user counts. Integrate the Vercel AI SDK and Anthropic API to create a 'Galileo AI Summary' feature: when viewing an error or session, send the chronological event sequence and stack trace to Claude to generate a natural language explanation of what went wrong, severity scoring, and recommended reproduction steps. Display these insights cleanly in the dashboard UI.06Product Analytics & UX Performance Charts
Build product analytics dashboards for conversion funnels, path analysis, and Core Web Vitals telemetry.
Create an Analytics view featuring conversion funnels and timeseries charts for performance telemetry (Core Web Vitals like LCP, CLS, FID, plus CPU and memory usage). Allow users to define custom event funnels and filter metrics by date range or session attributes. Ensure charts render cleanly using Recharts or Tailwind CSS primitives connected to aggregated Turso query results.

Vibe code LogRocket: FAQ
- Can you vibe code LogRocket yourself?
- Serious undertaking — 38/100 vibecodeable. Build a thin personal error and event log viewer, but keep paying for LogRocket if you need production-grade session replay at scale. The single biggest catch is writing a performant DOM mutation recorder that doesn't tank host application performance.
- How long does it take to vibe code LogRocket?
- 3-6 weeks of intensive development — roughly 45-60 hours of hands-on time with an AI coding agent.
