Audience
Python web developers, from serious hobbyists to small teams, who build with Flask, FastAPI, or Django and want to ship to production without becoming DevOps experts. It fits indie hackers, freelancers, backend and full-stack developers, and CS students with side projects who use AI coding assistants but have been burned by tools that break databases or treat Python as an afterthought.
About marpy
marpy is a browser-based AI coding IDE and deployment platform built specifically for Python web developers. Most vibe-coding tools were built for JavaScript and bolt Python on as an afterthought. marpy is opinionated entirely around Flask, FastAPI, and Django.
Every project gets a managed MariaDB instance with Alembic migrations enforced by default. Destructive commands like DROP TABLE are blocked in production at the platform level, not by a linter you can ignore. The AI assistant indexes the real PyPI docs for every package you install, so it writes against your actual runtime. Bring your own keys for Claude, GPT-4, Gemini, or Groq and pay nothing for AI tokens.
Deploy to isolated Kubernetes namespaces (dev, staging, prod) with preview URLs, SSL, and date-based audit tags that make rollbacks trivial. The IDE includes the Monaco editor, a full terminal, git tooling, and live preview, all in the browser.
