Flow
Flow is a modern, intuitive web application designed to simplify and democratize web scraping and data extraction.
Project Scope
What this project covers — systems owned, responsibilities, and integrations.
The Story
Flow emerged from a simple observation: extracting valuable data from the web shouldn't require an engineering degree or hours of writing brittle scraping scripts. Marketers needed leads, researchers needed datasets, and developers needed a faster way to prototype web automation. We built Flow to bridge this gap. By combining a visual node-based engine with robust underlying orchestration, Flow democratizes web scraping. Our visual canvas allows users to visually define what they need, step-by-step, while the engine handles the complexities of pagination, rate limiting, and dynamic content rendering.
Challenges Faced
Real technical and design problems encountered during development — and how they were resolved.
Rendering complex node graphs without performance degradation
Large workflows with 50+ nodes caused re-render storms in React. Resolved by isolating node state into individual Zustand slices per node ID, so edge/position updates for one node don't trigger re-renders across the entire canvas.
Handling dynamic, JavaScript-heavy scraping targets
Many modern websites rely on client-side rendering, making simple HTTP-based scraping useless. Flow wraps Puppeteer/Playwright inside a job runner, spawning a headless browser per workflow execution to ensure JS is fully rendered before element selection.
Anti-bot detection and rate limiting
Target websites frequently blocked automated requests. The engine integrates configurable request delays, randomized user-agent rotation, and proxy rotation support — making scraping workflows significantly more resilient.
Real-World Impact
Measurable outcomes and meaningful results this project delivered.
No-code web automation
Non-technical users (marketers, researchers) can build robust scraping workflows through the visual canvas without writing a single line of code.
Handles JS-rendered content
Unlike simple HTTP scrapers, Flow's Puppeteer engine reliably extracts data from SPAs, infinite scroll pages, and login-gated content.
Workflow versioning
Users can save, fork, and compare different versions of their automation flows, enabling iterative refinement without fear of breaking working configurations.
