phoenix.new

Phoenix.new is a prompt-driven, web-based application development platform for developers and non-technical founders who want to prototype and ship working real-time apps by describing them in natural language.

Key capabilities include:

• LLM-powered coding agent that generates application code from prompts, then tests and debugs with automated self-healing behavior
• Real-time preview via a hosted dev server and shareable live URL, plus the ability to view the generated code while iterating
• Real-time app building blocks such as authentication (user accounts, login/logout), queue management for user matching, and support for real-time video chat (via Daily.co)
• In-product deployment to cloud infrastructure such as Fly.io, without local installation

Pricing: Unknown.

Notable for pairing a prompt-driven workflow with the Phoenix Framework (clustering, PubSub, presence) and positioning itself as Fly’s entry into prompt-to-deployed real-time application development, aimed at getting functional prototypes online quickly.
