LoadForge
Self-hosted API load testing
Enterprise-grade API load testing with real-time performance metrics and AI-assisted bottleneck diagnosis orchestrating k6 load generators via distributed workers.
Problem
Every load testing tool I tried was either too heavy — enterprise software requiring days of setup — or too light — a shell script that hits a URL and returns average latency.
Approach
Built a platform you can self-host in minutes that gives real, production-quality signal about what breaks under load. It orchestrates k6 load generators via BullMQ workers and uses an integrated AI layer to analyze time-series data and diagnose bottlenecks.
What shipped
- Managed massive influxes of time-series data during high-throughput tests.
- Implemented AI evaluation of time-series data by summarizing metrics into statistical percentiles before prompting.
- Built robust defensive programming for native subprocesses signal handling.
