---

VibeLens parses, visualizes, and analyzes conversation histories from Claude Code, Codex CLI, Gemini CLI, and Dataclaw — giving you full observability into your AI-assisted development workflow.

One command. No config. Works with your local ~/.claude/ sessions out of the box.

pip install vibelens && vibelens serve

Analytics Dashboard Aggregate stats, cost estimation, and usage trends over time.	Activity Heatmap & Charts Peak hours, project breakdown, model and tool distribution.
Session Browser Browse by project, view step-by-step timelines with tool calls.	Conversation Flow Phase detection across exploration, implementation, and verification.

Why VibeLens?

• What did my agent actually do? Step-by-step timeline with tool calls, token counts, and elapsed time
• How much is it costing me? Per-session and aggregate cost estimation across 45+ models from 12 providers
• Where are the bottlenecks? Conversation flow diagrams with phase detection and tool dependency graphs
• How do I share a session? Shareable permalink URLs with read-only session replay
• What are my usage trends? Analytics dashboard with heatmaps, model distribution, and project breakdowns

Quick Start

Install and run

pip install vibelens
vibelens serve

Or run without installing:

uvx vibelens serve

VibeLens opens your browser and reads your local ~/.claude/ sessions by default.

Development install

cd VibeLens
uv sync --extra dev
uv run vibelens serve
