px0 is an open-source prompt infrastructure toolkit that lets you version, update, and govern prompts in production, eliminating the need to hardcode prompts or redeploy your application for prompt changes.
- Decouple prompt strings from codebase definitions to manage templates in a single control plane.
- Promote new prompt versions instantly with zero CI/CD overhead or application redeployments.
- Share standardized prompt templates across teams to align engineering practices.
- Govern production environments by restricting version promotion to authorized administrators.
Follow these steps to spin up the local services and send your first request. Refer to the Getting Started Guide for detailed verification and user registration instructions. For telemetry setup, metrics observation, and benchmarking details, refer to the Telemetry and Benchmarking Guide.
Clone the repository, configure the environment, and boot the background containers in detached mode.

px0 includes a built-in concurrent load testing utility located at cmd/loadtest/main.go. This script automatically handles transaction-safe database setup, concurrent execution, and lock-free metric collection.
Refer to the Benchmarking and Performance Guide for execution flags, metric details, and latency percentiles.
