Project mention: A web page that shows you everything the browser told it without asking | news.ycombinator.com | 2026-05-08
Don't know about easy but their JS lib doing this is quite good:
https://github.com/fingerprintjs/fingerprintjs
Honestly surprised to see it licensed as MIT now too. It was something less permissive before. They aren't doing anything too crazy, more like being the first ones to be open about it.
I couldn't imagine what else companies like Google or Meta or TikTok can extract out of it that no one else can't.
Those advertisers benefit from monopolistic markets with zero regulation while owning the platforms they sell advertising on that requires their explicit malware in order to use, what is unique about their finger printing versus what fingerprintjs provides?

stagehand
The AI Browser Automation library by Browserbase. Write web automation scripts in plian english with primitives like act('click this button'), extract('get the price for xyz product'), and observe('find the submit button').
Project mention: Browser Tools for AI Agents Part 1: Playwright, Puppeteer, and Why Your Agent Picked Playwright | dev.to | 2026-04-26Right. So Stagehand (21.8k stars) is Browserbase's TypeScript SDK and it does something properly clever. It wraps Playwright with three AI primitives: act() (do something on the page), extract() (pull structured data out), and agent() (let the LLM figure out a multi-step flow). On paper that sounds like yet another Playwright wrapper. It isn't.

Project mention: OpenClaw Creator Spent $1.3M on OpenAI Tokens in 30 Days | news.ycombinator.com | 2026-05-16
tl;dr Peter Steinberger shared a product demo for CodexBar [0] with a graph of OpenAI token usage. This graph shows one million spent, prefers gpt-5.5 and spent twenty thousand today.
[0] https://github.com/steipete/CodexBar
However, I do not see a strong reason to believe that this is his actual personal usage. It could be all openclaw usage or some subset of openai usage, given that he is inside them. I suspect it is far more likely to be fake data [1] that exercises the graph library in a visually satisfying way. Notice that it has no usage for a 'week' after April 15 (a Wednesday), but picks up a bunch later. As marketing copy it needn't have any basis in reality [2]. I should hope openai would put a procedure in front of their entrepreneur acquisition that prevents accidentally exposing trade secrets [3].

Something I keep seeing across teams, especially with people who are getting comfortable with tools like db-migrate or Kysely, is a very specific habit: they reach for raw SQL for everything.

Project mention: Let your Coding Agent debug the browser session with Chrome DevTools MCP | news.ycombinator.com | 2026-03-15
I do this via BrowserOS -- https://github.com/browseros-ai/BrowserOS
It has an in-built MCP server and I use it with claude code, codex and like it quite a lot.

Yes it does! I was trying to draw an analogy there, I think it would be better to state as - iroh is similar to WebRTC + PeerJS[1] which only works on browsers, generally[2].
[1]: PeerJS(https://peerjs.com/) is a library to use WebRTC w/o any boilerplate code.
