Redis Complexity
Analyzer

A real-time TUI tool to analyze your Redis database complexity and data type distribution. Read-only — it never modifies your data.

What it does

Everything you need to understand your Redis instance before migrating

Real-time TUI Dashboard

Live-updating terminal interface showing all metrics with current, average, and maximum tracking across your session.

Data Type Distribution

Samples keys to determine your data type mix — strings, hashes, lists, sets, sorted sets, streams, plus Redis modules like JSON, TimeSeries, Bloom filters, Graph, and Search.

Database Metrics

Memory usage, key count, ops/sec, and connected clients with historical tracking of current, average, and peak values.

Eden Migration Estimate

Get an estimated migration time and complexity score (0–12) based on throughput, type complexity, connected clients, data scale, and key count.

Multiple Output Formats

Interactive TUI dashboard for exploration, one-shot console output for quick checks, or JSON for automation and CI pipelines.

Read-Only & Safe

Only uses read-only commands — INFO, DBSIZE, SCAN, TYPE, PING. Never modifies your data. Safe to run against production.
