LoadForge v1.0.0 — Open Source Release

High-Concurrency Local Load Testing & Performance Observability

LoadForge is a local-first alternative to JMeter, Locust, and k6 with zero external dependencies. Execute high-concurrency traffic tests, inspect real-time Locust-style graphs, detect endpoint bottlenecks, and export multi-format HTML/PDF reports.

Engineered for Serious DevOps & Engineers

High-concurrency traffic generation coupled with automated root cause diagnostics.

🚀

High-Concurrency Go Engine

Goroutine worker pool architecture with tuned HTTP/1.1 & HTTP/2 connection reuse generating tens of thousands of requests per second from your laptop.

📊

Locust-Style Real-Time Telemetry

Live WebSockets telemetry streaming Total RPS vs Failures/sec, P50 Median, P95/P99 tail latencies, active user ramp curves, and HTTP status distribution.

⚡

Automated Bottleneck Engine

Pinpoints breaking point concurrency and classifies problems using a 4-step framework: Observation → Evidence → Likely Root Cause → Recommended Action.

🔄

Multi-Step User Journeys

Construct realistic multi-step user scenarios (Login → Extract JWT Token → Fetch Products → Checkout) with dynamic variable interpolation.

📥

OpenAPI, Postman & cURL Importer

One-click converters for OpenAPI 3.0 / Swagger specs, Postman Collections, cURL commands, and HAR files straight into test scenarios.

🛡️

Localhost Isolation & Secret Masking

Local-first architecture storing test history in local SQLite (`~/.loadforge/loadforge.db`) with automatic masking of Bearer tokens and passwords.

Local-First Zero-Dependency Stack

Designed to run standalone on your local workstation without requiring MySQL, Redis, Node.js, or Docker containers.

Go Load Engine: Asynchronous goroutine worker pools with sub-millisecond atomic quantiles math.
React + Tailwind Frontend: Embedded directly into Go binary (`embed.FS`) for instant single-click dashboard access.
Embedded SQLite Storage: Zero database configuration. Preserves all test run histories locally.
WebSockets Telemetry Hub: Sub-second real-time metric broadcasting to browser clients.
