Reflex

One engineer. 200+ users. 2,000+ VMs. Dell Technologies's support engineers couldn't reproduce customer environments fast enough. Spinning up a multi-node cluster took a handful of senior people and a pile of CLI commands. A Senior Principal Engineer spent six months evaluating React, Svelte, and Vue. Every path meant a parallel JavaScript stack to maintain. Then the team tried Reflex. Working demo in a week. Pure Python meant they reused every backend service already built. No rewrite, no JS, no frontend hire. The result is Dynamic Lab: any engineer picks a product and version and spins up a fully configured cluster in minutes, right from the browser. Self-hosted on Dell's own infrastructure. One Python engineer shipped the whole thing. That's the point. https://lnkd.in/gjP4r3em

Our latest Reflex feature hit the front page of Hacker News yesterday! This thread made one thing clear: people are fed up with how slow and expensive computer-use agents are. We solved it. In Reflex 0.9, every Reflex app is optimized to work with agents out of the box. Every UI component and state handler is automatically an API endpoint. Humans navigate the UI, agents call the endpoints. Same app, no parallel codebase. Which means: - You ship once. Every UI feature is automatically an agent feature. No second API to design, document, or keep in sync. - Your design freedom comes back. Move buttons, restyle modals, restructure flows. Endpoint-driven agents don't notice and don't break. Building an app for humans is now the same act as building an app for agents.

We released Reflex 0.9 - every action in your app is now callable by an AI agent out of the box. We ran a benchmark comparing two approaches to letting AI agents interact with a web app: - A vision agent (browser/computer use) that screenshots the UI and clicks around - An API agent that calls HTTP endpoints directly The task for both agents was to find a "Smith" customer with the most orders, accept their pending reviews, and mark their most recent order as delivered. We chose this task since it's similar to automation work a typical tool sees. The vision agent took 550k tokens and 17 minutes on average. The API agent took 12k tokens and 19.7 seconds. Of course, API agents are faster and more token efficient since they don't need to take screenshots and directly interface with the UI. The problem is many apps don't have APIs for every action, since it takes engineering overhead to build and maintain each separate API codebase. We built a plugin for Reflex that auto-generates HTTP endpoints from your app's existing event handlers. Your app has a button with an on_click handler, the plugin exposes that handler as an endpoint. An agent can call the same function a human click triggers. No separate API to build or maintain. As agents become a bigger share of your app's users, every action needs to be callable by code, not just from the UI. Benchmark: https://lnkd.in/gg7gSzXn
