Introducing the new pen.dev, an agentic canvas for building bold ideas. Never start from scratch. Import any website or webapp to the canvas, iterate, and push back to code. Update or download today.

Vectors and shaders are an epic combo. @QuiverAI Arrow 2 🤍 @pendev shaders

Today we are re-launching shaders in pen.dev. We call them Vibe Shaders. There's nothing else like them. They live next to your .pen files as GLSL files and can be easily vibecoded right on the canvas. Built by designers for designers. They deserved a special Shader Mode, a focused mode to finetune the uniforms directly in the context of your design. In addition to the classic Shader Fills, we've also added Shader Effects. This allows for incredible creative flexibility, as it applies the effect on a whole object tree that's part of a particular frame and you can change everything live, no hustling with textures. Additionally we are also launching Background Shaders, they sample the texture from everything below the object. Imagine creating your own custom background blur or a partial dither effect for objects below a frame. You can also create shaders with 3D transformations to vector logos or build custom shader brushes for vectors paths. Forget having just a fixed set of shaders, this is next level and only possible, because we have a full control over our custom renderer. We also automatically compute the SDF (signed distance field) in realtime, so vectors that have applied shaders can be changed directly on canvas without the need to re-export a new SDF file, an incredible time-saver. Look for the samples in Goodies, which has been updated with a ton of new examples. Or simply pair @pendev with the latest models, drop in a bunch of images, ask agent to build you a shader and it's guaranteed you will feel an explosion of your creative superpowers!

The Shader Mode is a focused mode for tuning the shader. There is also a new shortcut button to get into the shader instantly.

Can someone finally vibecode this?

This is actually really cool. Full MCP Servers support in @pendev!
It's now possible to connect pen.dev directly to an external MCP Server like @mobbin, @notion and @linear and attach them to the context. Quite powerful!

Gamechanger! 🔥
Ultrafast is rolling out today for GPT-6.1 Sol in the API, Codex, and ChatGPT Work. Near-Astra intelligence at up to 8x faster speeds than Sol Standard, so you can build as fast as the ideas come.

Visually feels like Opus 4.5/Opus 4.6 levels, which we thought was INSANE at the beginning of this year. If we continue with this tempo. Next Haiku will be able to design 3D quite good soon.

Watching wacho post this, while I am flashing ROM with my version of "gradient snake" for gameboy/modretro, that eats color swatches 🤓 #snakenight
Your first addiction is back. 🐍 I built snake3330.app for that old Nokia feeling. Tiny screen. One more round. Unlock covers, challenge friends, private leaderboards + lo-fi radio. Built with muse, Codex & ElevenLabs. Shipped on Vercel.

This was 10x boost for my dev speed - @gitbutler, I now work on multiple branches at the same time in the same running build with multiple agents, it works great for non-conflicting things, I am always building multiple features at the same time - when things do in fact conflict, usually when I want to review someone's else branch, an agent resolves it within a minute or less - no complicated learning of git butler, I control it via agent, it manages everything, I almost never use the butler app, all done via cli This will be 100x boost: - now that multi-branch workflow is solved, the next massive boost will come from multiplayer git butler like workflow, where we in fact work on multiple branches at the same time together with agents, everyone's always on the latest. It will happen sooner than people think. Going back to standard git workflow will feel like working with a shovel instead of an excavator

Omg, someone from @X please block all the Reuters, Techcrunch, Bloomberg… impersonators. This is getting out of hand, there isn’t a day I don’t receive a scammy DM from these “reporters”.

Present mode now has 100% zoom mode. This is great for presenting long websites. We have also added zoom animations for higher comfort when navigating the canvas.

Due to popular demand, we have added Queue and Steering in the chat agent. You can now keep sending message after message and they will be queued in an editable queue. But you can also click "Steer", which will immediately inject the message into the agent's context on the spot without waiting for the turn to finish.
