Show HN: Selector Forge – browser extension for AI-generated resilient selectors

Hi HN, I'm Ahmad from the Intuned (https://intunedhq.com) team. Today, we're releasing and open-sourcing Selector Forge (https://selectorforge.ai/), a browser extension that generates reliable CSS/XPath selectors using AI.

You can use it to create a selector for a single element or for an array of elements. The selectors it creates are meant to be "semantic" and more resilient to page changes than what Chrome DevTool’s “Copy Selector” (and other similar extensions) give you. Those tend to hand you something brittle like `#top > div.w-100.ph0-l.ph3.ph4-m > h1 > span`, which can break with a minimal page change. Selector Forge aims for selectors that don't break as easily. Here are some selectors that Selector Forge created: `//div[@aria-label="Showing weekly downloads"]//p[@aria-live="polite"]` (item selector) and `//*[local-name()='svg' and @aria-label="Download statistics"]/following-sibling::div` (list selector).

Here is a video demo of using the extension: https://www.youtube.com/watch?v=8IjjeDQkKmo

Backstory: For the past couple of years we've been building Intuned Agent, a coding agent for building and maintaining browser automations. We quickly figured out that the most fragile part of any browser code is usually the selectors and that creating good selectors can go a long way towards improving the quality and reliability of the automation itself.

So we abstracted selector creation into its own agent, wrapped it as a tool, and let our codegen agent call it. LLMs by default don't do a great job generating good selectors, so this turned out to be really useful and improved the code our agent generates.

We recently thought that this piece (the selector agent/creation) is useful on its own (outside our platform) so we packaged it as a browser extension. That’s this post!

Selector Forge is open source, and the version in the browser stores (Chrome and Firefox) is free for up to 200 selectors/month. Unlimited usage is part of our paid plans.

We realize most developers aren't writing this kind of code by hand anymore, so the next step is exposing this functionality in a way coding agents can call directly, over a CLI or MCP. Here's our roadmap: https://github.com/Intuned/selector-forge#roadmap

Excited to hear your thoughts, questions, and feedback!
