promptman

What it does

Promptman is a developer tool for managing prompts in agentic AI applications. It helps teams version, organize, test, and reuse prompts across agents, tools, and environments—so prompt logic doesn’t turn into untraceable strings scattered across code. Built while developing real multi-agent systems, Promptman treats prompts like first-class artifacts: editable, comparable, and auditable. It’s designed for developers who want more control and less chaos as their agent workflows scale.

Manage AI prompts like infrastructure. Version control, stage-based deployments, and runtime API access for your prompt library. MCP-native integration for Claude Code.

Version prompts and agent context, promote tested changes across stages, and fetch the right version at runtime via REST or MCP. async function generateResponse (userInput) { // Fetch the production prompt const res = await fetch ( 'https://api.promptman.dev/v1/prompts/customer-service-agent?stage=prod' , { headers: { 'X-API-Key' : process.env.PROMPTMAN_API_KEY } } ); const { content, variables } = await res. json (); // Use the prompt with your LLM return llm. chat (content); } Featured on First-class MCP support. Let AI coding assistants manage prompts directly via MCP. Track changes, rollback when needed, and maintain a complete history of your prompt evolution. Organize prompts into…from promptman.dev

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
