Features

GalataJ brings performance insights directly into your development workflow.

Inline Performance Hints

See metrics directly above your methods — no need to switch windows or tools.

Inline Hints

What you see:

Avg time — Average execution time across all calls
Max time — Slowest execution in recent window
Calls — Total number of invocations
Trend — Performance change indicator (↑ slower, ↓ faster)

Hover over any hint for more details.

Profiler Panel

A dedicated panel showing all profiled methods in one place.

Profiler Panel

Panel features:

Sort by any column (time, calls, trend)
Filter by package or class name
Click any method to jump to source
Real-time updates while profiling

AI Integration

Pro Feature

AI context files require a Pro license.

Get AI-powered insights from your profiling data.

How it works:

GalataJ generates live-performance.md in your project
Point your AI assistant (ChatGPT, Claude, Cursor) to this file
Ask questions like “Why is OrderService slow?”
Get specific optimization suggestions

Live Performance Markdown

Built-in prompts:

Analyze performance regressions
Suggest concrete optimizations
GC & memory analysis
IO vs CPU diagnosis

Custom prompts: Create your own prompts for your specific use cases (N+1 detection, framework-specific analysis, etc.)
