What PromptWorks is

PromptWorks is a free, open-source workspace for teams managing prompts, running evaluations, and improving prompts with AI assistance. Teams can create prompt versions, organize them with tags, record authorship, and keep audit records. Batch testing runs across prompt versions, models, parameter sets, and test samples, with progress tracking and result comparisons. Outputs receive scores from 0 to 100 across dimensions such as accuracy, completeness, clarity, and stability. PromptWorks uses evaluation results to suggest rewrites, model and parameter advice, and validation plans; rewritten drafts can be saved as new versions. It also manages model providers and configurations centrally, with invocation records for model selection, cost review, and A/B experiments. Setup documentation names OpenAI and Anthropic API keys as configurable integrations. The backend exposes API endpoints for prompts, prompt tests, and language models. Teams can run it on the web or self-host it. Documented Docker Compose deployment includes frontend and backend images plus PostgreSQL and Redis services; published images support Linux AMD64 and ARM64.

Who it suits

PromptWorks suits teams maintaining shared prompt assets, testing changes, reviewing model choices, or tuning parameters. Its self-hosting and API options also fit teams integrating prompt workflows into their systems.

What it does well

Batch tests compare prompts across models and samples
Scores outputs across four named dimensions
Tracks versions, authorship, and audit records
Docker images support Linux AMD64 and ARM64

What to know first

Production setup recommends PostgreSQL and Redis
OpenAI and Anthropic integrations require API keys
No security certification or compliance standard is stated

Verdict

PromptWorks brings version management, batch evaluation, and model records into one workspace. Teams considering self-hosting should account for its documented PostgreSQL and Redis components.
