Tabstack gives AI agents and apps finished output from the live web in a single API call. Extract structured data to a schema you define, convert pages to Markdown, run cited multi-source research, and automate browser tasks. Every call returns exactly what you asked for. Built for developers shipping autonomous agents and those adding web interaction to an existing app or stack. Built by Mozilla, with ephemeral processing, no model training on your data, and robots.txt compliance by default.
This is the 6th launch from Tabstack by Mozilla. View more
Tabstack Browser Automation
Launched this week
Give /automate a task in plain English and it drives a real browser to do it: navigate a site, click through a multi-step flow, fill a form, reach a page that only renders after interaction. The result streams back in one API call.
It's an API you call, not a framework you install. Browser and LLM included, nothing to host, no concurrency ceiling. Accessibility-tree automation spends 60 to 80% fewer tokens than screenshot-based agents.
Built by Mozilla. Ephemeral, no training on your data.

Tried it on a couple research queries and the cited multi-source output was solid. Nice that it returns clean Markdown instead of forcing me to parse raw HTML.

@kumsalh9541 Thank you, love that it worked well for you. Cited output you can actually trust, and clean Markdown you don't have to fight with, that's a win! Appreciate you trying it.
finally tried this and the schema extraction felt shockingly clean, called it for a few messy product pages and got structured JSON back without babysitting.

@nehir238420 incredible! That's awesome to hear.
Spent a few minutes poking around the schema extraction and it actually nailed a messy recipe page on the first try. The robots.txt compliance detail is a nice touch for anyone tired of sketchy scrapers.

@nazls86733 thank you! I actually built an app with Tabstack doing the same thing. I'm using extract and generate, though. I feed it the recipe url, it extracts the data, then generates a clean, easy to follow recipe. Most of the ones online are such a mess to read with ads, and otherwise. Glad you found success. Hopefully you can find more ways to integrate it. I have it available to my Hermes agent so its constantly grabbing for it to do various things I ask it to do as the tool to surface the data and navigate the web.
Finally tried Tabstack and the schema-defined extraction is genuinely useful, no more wrestling with messy scraped HTML. Love that robots.txt and ephemeral processing come baked in by default.

@zmra1131403 love it! feel free to add your review here: https://www.producthunt.com/products/tabstack/reviews/new
Mozilla backing this is what got me to try it, and the schema extraction actually nailed a messy product page on the first try. Glad my data isn't getting fed into some training pipeline either.

awesome! and yes, @Mozilla makes it different. private by default, transparent by design.
The robots.txt compliance baked in by default is a really thoughtful touch, especially from Mozilla. Feels like they actually thought through the trust layer for devs shipping agents, not just the shiny API surface.

@eyupk60283 you're spot on - @Mozilla actually cares about developers and humans. ❤️
Not sure that my feedback can be useful, because I`m not too deep in the topic. But I love homepade of your website - it is clear and has all information needed. Keeping instruction near the start button was a very smart decision.

@julia_shtogren you just made my heart so happy! That website is a labor of love. I've been building each stack page as we've launched on Product Hunt. I strategized the approach, wrote the messaging, designed it (from where it was), and built it. I'm so proud of the work and I'm really really thankful for your kind words. Let me know if you try Tabstack or if you need anything. Always here to help. 🫶
@tessak22 Tessa, it's so great that you put so much love into your product and made it so thoughtful! I always admire people who fearlessly bring new ideas into the world.
Wishing you all the best with it! And I'm curious - what happens after the Product Hunt launch? Are you taking a break to collect feedback first, and then jump straight into improvements?

We start planning the next launch 🔥

@julia_shtogren we are continually taking in feedback. Its a focus for our GTM efforts to truly understand the market and give people what they actually need and want. Like @fmerian said, though, plan the next launch!
