Analytics Platform — Self-Hosted Session Replay & Visitor Analytics
One-liner Introduction
Get core Datadog RUM features for free on your own server. Visitor screen recording, traffic analysis, error tracking — all with a single line of installation.
Detailed Description
"I want to know what visitors did before leaving our website, but Datadog is too expensive, and Hotjar stores data on overseas servers..."
This platform started from that very concern. It's a self-hosted visitor analytics platform built in a day with Claude Code.
Solves These Problems
1. "I don't know where visitors are dropping off"
Replay visitor screens exactly as they happened with session replay
Track page navigation paths with a user journey timeline
Jump directly to the point of a click within the replay
2. "I'm spending on ads, but I don't know if they're effective..."
Automatic UTM parameter tracking (Google Ads, Facebook, etc.)
Analyze sessions/visitors by acquisition channel (organic, paid, social, direct)
Identify which campaigns contribute to actual conversions
3. "I don't know about site errors until a customer tells me"
Automatic JS error capture (uncaught, Promise rejection, resource load failure)
Instantly view the replay of sessions where errors occurred
Understand the scope of impact with error counts per session
4. "Customers say a button doesn't respond, but I can't reproduce it"
Automatic detection of Rage Clicks (repeated clicks in the same spot)
Detection of Dead Clicks (clicks with no response)
Detection of Error Clicks (clicks followed by an error)
Prioritize UX improvements using Frustration scores
5. "I want to use Datadog, but hundreds of thousands of won per month is too much..."
Completely free (AGPL-3.0 open source)
Install on your own server → data never leaves your control
No SaaS vendor lock-in, scalable when you need it

Development Process
Developed in a single day through conversations with Claude Code (Opus). From SDK design to ClickHouse schema, replay player, and Datadog-style UI, everything was implemented in collaboration with AI.
Particularly challenging aspects:
GCS storage/playback pipeline for rrweb session replay
ClickHouse DateTime64 type compatibility issues
Asynchronous context collection timing issues in the SDK
Resolving port conflicts with existing servers (groupware, modushare)
All debugged and resolved through conversational interaction.
