TL;DR: Replay uses AI to reconstruct working UI code from video recordings, offering a novel approach to design challenges by understanding user behavior, not just visual elements.
UI design is often a bottleneck. Iterating through endless design tools, hand-coding components, and trying to perfectly replicate a desired user flow is time-consuming and prone to error. What if you could skip the manual translation and directly transform user behavior into functional code?
That's the promise of Replay.
Replay: Turning Video into Working UI Code#
Replay isn't just another screenshot-to-code tool. It's a revolutionary approach to UI generation that leverages AI to analyze video recordings of user interactions and reconstruct functional UI components. This "Behavior-Driven Reconstruction" allows you to capture complex user flows, subtle animations, and intricate interactions – all from a simple video.
The Problem with Traditional UI Design#
Traditional UI design workflows are often inefficient and disconnected from real user behavior. Designers create mockups, developers translate them into code, and then user testing reveals discrepancies that require further iterations. This cycle is costly and time-consuming.
Here's a breakdown of the common pain points:
- •Manual Translation: Converting design mockups into code is a manual, error-prone process.
- •Lack of Behavioral Context: Static designs don't capture the dynamic nature of user interactions.
- •Iterative Bottlenecks: User feedback often leads to extensive rework and delays.
- •Tool Fragmentation: Switching between design, prototyping, and coding tools creates friction.
How Replay Solves These Challenges#
Replay addresses these challenges by providing a seamless bridge between user behavior and functional code. By analyzing video recordings, Replay understands what users are trying to do, not just what they see. This behavioral context enables Replay to generate more accurate, robust, and user-centric UI components.
Here's how Replay works:
- •Record: Capture a video of a user interacting with an existing application, website, or even a hand-drawn prototype.
- •Analyze: Replay's AI engine analyzes the video, identifying UI elements, user actions, and underlying logic.
- •Reconstruct: Replay generates clean, functional code that replicates the observed user behavior.
- •Customize: Fine-tune the generated code, integrate it into your existing codebase, and deploy your UI.
Key Features of Replay#
Replay offers a range of features that streamline the UI design process:
- •Multi-Page Generation: Reconstruct entire user flows spanning multiple pages.
- •Supabase Integration: Seamlessly connect your UI with a Supabase backend.
- •Style Injection: Customize the look and feel of your UI with CSS.
- •Product Flow Maps: Visualize user flows and identify areas for optimization.
- •Behavior-Driven Reconstruction: Understands user intent from video, not just visual elements.
Replay vs. Traditional Design Tools#

markdown> **TL;DR:** Replay transforms UI design by generating working code directly from video recordings, capturing user behavior and streamlining the development process. UI design is often a bottleneck. Teams spend countless hours crafting pixel-perfect designs, only to face frustrating translation challenges when turning them into functional code. This leads to delays, inconsistencies, and ultimately, a less-than-ideal user experience. But what if you could bridge the gap between design and code with a single, powerful tool? That's where Replay comes in. ## Replay: The AI-Powered Solution for UI Design Challenges Replay is a game-changing video-to-code engine that leverages the power of AI to reconstruct working UI from screen recordings. Unlike traditional design tools that rely on static mockups, Replay understands the dynamic nature of user behavior and translates it directly into functional code. This "Behavior-Driven Reconstruction" approach revolutionizes the UI design process, saving time, reducing errors, and ensuring a more user-centric outcome. ### The Frustrations of Traditional UI Development The traditional UI development workflow is riddled with inefficiencies: * **Design-to-Code Gap:** Translating static designs into interactive code is a manual and error-prone process. * **Lack of User Context:** Designs often fail to capture the nuances of real user interactions. * **Slow Iteration Cycles:** User feedback leads to extensive rework and delays in deployment. * **Tool Fragmentation:** Switching between design, prototyping, and coding tools creates workflow friction. ### Replay's Innovative Approach Replay tackles these challenges head-on by providing a seamless and intelligent solution: 1. **Record User Interactions:** Capture a video of a user interacting with an existing application, a prototype, or even a simple hand-drawn sketch. 2. **AI-Powered Analysis:** Replay's advanced AI engine analyzes the video, identifying UI elements, user actions, and underlying behavioral patterns. 3. **Code Reconstruction:** Replay generates clean, efficient, and functional code that replicates the observed user behavior. 4. **Customization and Integration:** Fine-tune the generated code, integrate it into your existing codebase, and deploy your UI with confidence. Replay moves beyond static visuals, focusing on *understanding* user intent. This allows it to generate code that not only looks right but also *behaves* as expected. ### Replay's Core Capabilities Replay is packed with features designed to streamline your UI development workflow: * **Multi-Page Generation:** Generate code for complex user flows that span multiple pages. * **Supabase Integration:** Connect your UI seamlessly with a Supabase backend for data management. * **Style Injection:** Customize the visual appearance of your UI with CSS styles. * **Product Flow Maps:** Visualize user flows and identify areas for optimization. * **Behavior-Driven Reconstruction:** Captures and replicates user behavior from video recordings. ### A Comparative Look: Replay vs. Alternatives Let's examine how Replay stacks up against traditional design tools and other code generation solutions: | Feature | Figma/Sketch | Screenshot-to-Code | v0.dev | Replay , Replay | | Input Source | Manual Design | Screenshots | Text Prompt | Video NOW, LET'S TAKE A LOOK AT A CODE EXAMPLE: ```typescript // Example: Fetching user data from Supabase import { createClient } from '@supabase/supabase-js'; const supabaseUrl = 'YOUR_SUPABASE_URL'; const supabaseKey = 'YOUR_SUPABASE_ANON_KEY'; const supabase = createClient(supabaseUrl, supabaseKey); const fetchUserData = async (userId: string) => { const { data, error } = await supabase .from('users') .select('*') .eq('id', userId) .single(); if
