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.

Congrats on #3! What’s been the hardest part of building reliable browser automation for AI agents?
Wow, another great innovation. I hope this works both ways and makes it more standard to implement accessibility trees. A11y continues to be important in the agentic web!

@catalinmpit thanks for your continuous support! it means the world
Mozilla shipping something this developer-focused and privacy-conscious feels like a nice return to form. Loving that robots.txt compliance and ephemeral processing are defaults, not afterthoughts.

@savadgcs thank you. and yes, @Mozilla does care about developers and humans. ❤️

@savadgcs Thank you, this one means a lot. Defaults are everything, values you have to opt into aren't really values. Tabstack is privacy-first. Really glad that comes through.

@dax1 much appreciation!
Being able to just type '/automate' and dictate what I want to be done is an incredible UX. I'm going to explore hooking this up to my own agents today!

@aidanhornsby its amazing. We did a live stream this afternoon where I showed off my Hermes agent doing this very thing. All of the Tabstack endpoints are super helpful for agents. I'm currently building an enrichment tool with CRM sync using Tabstack in the stack multiple times. Its for my local OS and my agent. Fast-forward until you see a Telegram window.
@tessak22 Amazing! Thanks for sharing @tessak22 , what a great demo :)
