Products that do what Pilo – open-source agentic web automation engine by Mozilla does
Hello HN, We are the team behind Tabstack (https://tabstack.ai) - part of Mozilla. We just open sourced Pilo (pronounce PIE-low), the core engine that powers our automation platform. You can check it out on Github at https://github.com/mozilla/pilo. Pilo is an agentic web automation library. Instead of writing rigid scripts with CSS selectors, you give it a natural language goal (e.g., "Find the best pizza in Seattle and extract the ratings") and it autonomously navigates the browser to achieve it. We built this because we were struggling to make reliable agents…

Hi HN, My team and I are building Tabstack to handle the "web layer" for AI agents. Launch Post: https://tabstack.ai/blog/intro-browsing-infrastructure-ai-ag... Maintaining a complex infrastructure stack for web browsing is one of the biggest bottlenecks in building reliable agents. You start with a simple fetch, but quickly end up managing a complex stack of proxies, handling client-side hydration, and debugging brittle selectors. and writing custom parsing logic for every site. Tabstack is an API that abstracts that infrastructure. You send a URL and an intent; we…

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…

Libretto (https://libretto.sh) is a Skill+CLI that makes it easy for your coding agent to generate deterministic browser automations and debug existing ones. Key shift is going from “give an agent a prompt at runtime and hope it figures things out” to: “Use coding agents to generate real scripts you can inspect, run, and debug”. Here’s a demo: https://www.youtube.com/watch?v=0cDpIntmHAM. Docs start at https://libretto.sh/docs/get-started/introduction. We spent a year building and maintaining browser automations for EHR and payer portal…

Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

Hey HN, I’m Kiet, and I’m one of the co-founders of Onlook – an open-sourced desktop app that lets you visually edit your locally running React app, then write your changes back to code in real time. I posted the repo a few months ago [1] when it was just 2 weeks old. Since then, we’ve made some big changes/improvements. I wanted to share some of the updates we’ve made and add more technical details. Here are the three big ones: • Inserting new elements - Draw elements in the live page like a design tool and write them back to code. • Component detection - Detect when an element is a…
