X Bookmarks — 2025 KW09: Claude 3.7 Builds Better UIs Than Most Humans

@SullyOmarr — Claude 3.7 generating a landing page from one prompt

so they definitely trained 3.7 on landing pages right?

probably the best UI I've seen an LLM generate from a single prompt (no images)

bonkers

That's a strong claim, and given what I've seen from other models on UI generation tasks, I don't think it's hype. Claude 3.7 does something different — it actually thinks about layout hierarchy, not just markup. If this holds for complex pages, the "AI replaces Figma" conversation just got more serious.


@itsPaulAi — Anthropic releases a full guide to building AI agents

Anthropic has released a full guide to building AI Agents

There's both a YT video and a detailed blog post with all the necessary tips.

Everything you need to know below

(And links to resources)

Smart timing — everyone is building agents right now and most of them are doing it wrong. Anthropic's own guide is worth reading specifically because they're the ones building the models; they know which patterns actually work and which ones collapse at production scale. Bookmarked so I can point people at it instead of explaining orchestration patterns from scratch.


@tom_doerr — Workflow automation platform for orchestrating and scheduling code

Workflow automation platform for orchestrating and scheduling code

Honestly just saved this so I don't forget it exists. The niche between "cron job" and "full orchestration platform" is crowded, but anything that makes scheduling code feel less painful is worth checking out. The image in the tweet made it look clean enough to investigate.


@tom_doerr — Manage local domain aliases for development servers

Manage local domain aliases for development servers

Local dev domain management is one of those annoyances that everyone solves differently — /etc/hosts edits, Caddy configs, Nginx rewrites. If this tool actually wraps all of that in a clean CLI it'll get installed on every machine I set up. Worth a look.


@alexxubyte — 30 free APIs for developers

30 Free APIs for Developers

Makes sense as a reference — Alex's visuals are usually well-structured and the API lists tend to include things that aren't in the obvious places. Saved this one as a quick-lookup card for the next time I need a weather, maps, or finance data source that isn't behind an enterprise paywall.


@ChallengesCss — One CSS property to center uppercase text without hacky spacing fixes

CSS Tip!

Save this one line of code for the future!

No more hacky code trying to remove those spaces above and below an uppercase text. You can easily have a perfect centering for the text!

That's text-box-trim / leading-trim territory, and it's been something CSS has needed for years. Capital letters have optical gaps above and below them that throw off vertical centering — this fix is one of those things you don't notice until it's fixed, then you can't unsee the problem everywhere else.


@JoschuaBuilds — Upwork as a SaaS idea source

Upwork is a crazy source of ideas

there are many high paying gigs that could be solved with a small SaaS

Can really recommend scanning the gigs there if you are looking for your next project idea

Neat take — most "find your SaaS idea" advice goes straight to Reddit complaints or ProductHunt gaps, but Upwork actually shows you people already paying money for a solution. If someone is hiring a freelancer to do X manually every month, that's a validated problem with a price attached. Obvious in retrospect.


@GithubProjects — Self-hostable open-source invoice generator

A self-hostable open-source invoice generator app.

Every time I see a self-hosted alternative to a subscription SaaS that does one thing well, I bookmark it. Invoice generation is exactly the kind of thing that shouldn't require a monthly fee or sending your business data to a third party. This one goes in the "set it up on a VPS and forget it" list.
