Phoenix.new

Tool Category: 🔖
An intelligent Coding Agent-based development environment that runs entirely in the browser for developing Elixir/Phoenix cloud applications.


️ What does this tool offer? ✏

  • Phoenix.new lets you create an Elixir/Phoenix project in the browser, running a full development environment inside an ephemeral VM powered by Fly.io, including:
    - Root shell access, VSCode-like interface, real browser and live system previews.
    - Support for AI agents that can install packages, modify code, run tests, and actually deploy, without any local intervention.

  • Phoenix.new understands the Phoenix framework well, and automatically supports features such as WebSockets, LiveView, Presence, and real-time interactive interfaces.
    Agents can explore databases using CLI tools, suggest suitable Ecto schemas, and then generate full-fledged applications.

  • During a live demonstration at ElixirConfEU, a Tetris application was generated using Phoenix LiveView with just a single text description, highlighting the tool's live interaction and deep intelligence capabilities.

What does the tool actually deliver based on user experience? ⭐

  • Users described the experience as being like "live streaming an expert developer" building the app in front of you, and you can intervene and guide it at any moment.

  • A powerful tool for understanding the Phoenix framework; it writes code in a way that allows the user to visually and progressively understand the syntax and context.

  • The official tester confirmed that the current price is $20 per month, and that the tool is still in its infancy and may remain a preferred monthly option as support for frameworks expands.

Does it include automation? 🤖

  • Yes, it offers a significant degree of automation via agents:
    - An agent can generate code, run it, interact with the browser to simulate user interfaces, run tests, or generate Pull Requests and automatic revisions.
    - It can process and work independently without the need for the local environment or your manual intervention.
