Peace of mind from prototype to production
What it does
Phoenix is a toolkit that helps software teams build websites and apps that can handle large amounts of users and update in real time — think live chat, dashboards, or notifications that refresh instantly without the user hitting reload. It is designed to take a product reliably from early prototype all the way through to a large-scale, production-ready launch.
Why it matters for PMs
With over 22,000 stars and 435 contributors, Phoenix is one of the most trusted frameworks for building fast, scalable web products, meaning teams that adopt it can move quickly without having to rebuild their infrastructure as they grow. For founders and PMs, this translates to lower engineering costs and fewer growing pains when user traffic spikes — a meaningful competitive advantage at any stage.
