Told @tomkrcha weeks ago his team cooked with the latest version of @pendev and my co-founder's now shared the receipts. How Stephan rebuilt, massively extended, and launched a brand new @usebrief website in five days using: - @pendev - @superset_sh - @jamdotdev - @claudeai - @linear and, of course, @usebrief. usebrief.com/blog/idea-to-we…

Idea to website in five days | Brief

How a team of one redesigned and shipped 24 new website pages in five workdays with Pen.dev, Claude Code, Brief, Linear, Superset, and Jam.

Currently vibing some shaders in @pendev. Just describe what you have in mind in the chat and watch the agents bring it to life on the canvas.

So glad we were able to support @valiocon this year with @pendev. Epic times in Oceanside. Great job @drewwilson!

Wow! Thanks to everyone that decided to drop their thoughts about @valiocon! We ended up trending :D

New design, made with @pendev. Workforce management for field teams. Dark UI, one lime accent, nothing else.

My new fav is @pendev, best to bridge the gap from spec <> design <> code. Local Files, BYOK, its well polished unlike Claude Design & that magical feeling of using AI with its multi agents! AFAIK no one has this perfect mix. Love it!

Since @pendev has a built in browser, you can just drag SVGs onto the canvas, edit them as vectors and then export back as SVGs, either manually or agentically.
