we built blazing fast computer/browser use with Jev + Stagehand. this task cost $0.001 and executed at near instant speed (in a remote browser btw) the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then Stagehand executes it.

I built JevSearch, search the web & validate your results with Jev. Give a query and selection criteria, use Browserbase search to get the t25 results, then Jev scores and returns the t5 results. Jev often chooses urls outside of the initial top 5 as more relevant.

Before Kubernetes, engineers could get paged to manually scale infra at any time, even Christmas. In 2014 Google open sourced K8s, which now power a huge percent of the world's cloud infra. I wrote a blog about it, with fully interactive visualizations.

Instinct is an invite-only personal assistant meant to truly understand you and what you’re working on. It has a built-in secrets vault, is very good at using a computer, and can purchase items, all through an interface you already know and love: the Messages app. After months of vague investor posts hyping the product, Instinct recently came out of stealth and announced a round at $2.5 billion, the same valuation as Linear, which has been around for seven times longer.

OpenClaw can use Autobrowse to create and iteratively improve a Skill for any workflow. In this Craigslist extraction example we found a 68% speed up and 91% cost savings in 5 iterations. Halfway through, the agent found an exposed endpoint to speed up page navigation.

Hermes Agent can use Autobrowse to make better browser skills. In this HN example, 2 iterations take us from: 102 seconds -> 35 23 turns -> 8 $1.46 -> $0.28 Instead of clicking step by step it decides to eval JS directly on the page and save that workflow to a skill.

I built a centralized dashboard for UCLA students to see what's going on with the fires including live firemap, campus alerts, air quality, and even live feeds * all data sourced from .gov if you know ANYONE at UCLA send this to them. Link Below uclafire(.)org

Hermes Agent by Nous Research natively integrates with Give Hermes any URL and find a skill for it in our catalog, or create your own. Watch it find the NASA picture of the day for me.

i was reading through Modal's glossary to better understand how GPUs work. but what better way to learn than a visualization? so I had gpt 5.6 sol build an H100 in three.js based off the glossary. play around with it at

We just made Astra's computer use 2.5x faster with Stagehand. Astra works by executing code against the a11y tree, we built a translator that turns Astra's playwright commands into Stagehand. Astra chose to batch the entire logo into one command and one-shotted it.

i was curious how much faster gpt 5.6 sol on Cerebras actually was but didn't know exactly how to visualize it. then it hit me, all roads lead back to the language balls. at 750tps it's WAY faster than 5.6 sol served on their infra & AWS.

I built /schedule, but with access to your authenticated accounts in a secure browser. Using the Browserbase /cookie-sync skill, I saved my local browser cookies, and injected them into the remote browser in our schedulable Functions. The opportunities are endless, build Crons with CC to do ANYTHING a human can.

there's no excuse to be unemployed, even browser agents are getting jobs with Stagehand 🤘 & Browserbase, you can spin up concurrent browser sessions to apply to infinite jobs get yourself (and/or your browser agents) a job with our templates

Hermes agent supports Browserbase to browse and interact the web just like a human. You can add it when you setup your agent, or add it with Watch it add deodorant to my amazon cart, something much needed for engineers around the world.
