Simplex: Automate browser workflows using code and natural language
Simplex is an SDK that provides low-level functions you can use to create reliable web automations using code and natural language. Here's a quick video to show you how it works: https://www.loom.com/share/8d27d0f9e0f34c77a81b0ac770151c12 A couple weeks ago, we needed a way to automatically find 3D assets from the internet for one of our work contracts. We didn’t need an AI to choose all the steps for us autonomously — we knew generally what the flow to find items should be and just needed some intelligence to handle different webpage formats. Playwright couldn’t easily…

In plain words
Simplex is an SDK for building browser automation workflows that combine code with natural language processing. It helps developers automate web tasks by handling variable webpage formats while keeping human control over the workflow steps. The tool uses vision-based technology to interact with web elements reliably, allowing users to specify the general automation logic while the system adapts to different website layouts.

I created this tool a few months ago to automate some of my tasks. I use it to collect prices and files and to get notified when something changes on certain websites. The task runner uses Playwright. I'm not sure if it can be useful to anybody else besides me :) Any feedback is welcome.
Notte Browser Agents2025 · notte.cc · ▲275Hey HN, We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode. The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code. How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure Closest analog is Playwright codegen but: - Infrastructure…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
