TrafTest: A lightweight local traffic simulator & load sandbox with Bubble Tea TUI and Web UI

[eyejdev]

Hey everyone! 👋

I wanted to share TrafTest (traftest), an open-source traffic simulation and local load testing sandbox built in Go, powered by Bubble Tea and Lip Gloss for its interactive terminal experience! ⚡

🎯 Motivation

Setting up heavy tools like JMeter or k6 for quick local API checks during daily development often introduces friction. TrafTest aims to solve this by providing instant feedback with zero setup:

• Run load tests with a single command.
• Interactive terminal UI with live progress, real-time RPS, and latency percentiles (p50, p90, p95, p99).
• Dual experience: includes an embedded real-time Web Dashboard (SSE + Chart.js via go:embed) or pure TUI mode (--cli).
• Keyboard controls (Space to pause/resume in real-time, q to quit and export reports).

🛠️ Tech Stack

• CLI / TUI: Bubble Tea, Lip Gloss, Bubbles & Cobra
• Engine: Optimized Keep-Alive worker pool & RPS rate limiter in Go

🔗 Repository & Quick Start

• Repo: https://github.com/eyejdev/traftest
• Install: go install github.com/eyejdev/traftest@latest
• Run TUI: traftest --cli http://localhost:8080/api -c 10 -n 1000
