Visual Workspace for Agents Based on Unix
Hey HN, Thijs here! I'm the founder of Prototyper and today we're launching the first visual canvas built for agents. Couple of interesting lessons from building the product that I think are worth sharing: For the agents, everything is a file. In Prototyper, everything from plans, to apps, and diagrams, can be read as a file. We found that a filesystem is the most natural way for an agent to navigate: it discovers new content and functionality just by traversing the tree. We kept this layer deliberately thin and unopinionated, because it's the substrate, not the experience. It's the…

In plain words
Prototyper is a visual canvas designed for AI agents to plan, build, and organize work. It treats all content—plans, apps, and diagrams—as files in a filesystem structure, allowing agents to naturally discover functionality by traversing the directory tree. Built with a Unix-inspired architecture that works as a distributed, web-based kernel, it integrates with multiple AI models and harnesses without locking users into a specific platform.

From the sources
Prototyper is the first visual workspace for your agents and your team. Give Claude Code, Codex, Cursor, and other agents a shared canvas for plans, apps, and diagrams.
One canvas. Designers, engineers, and agents shipping the same artifact. Every idea you draw becomes real, running code. Try ten, keep the one. The prototype is the product. Move a shape and the code follows. Edit the code and the canvas catches up. One living artifact, from first sketch to production. Claude Code, Codex, Cursor, or Copilot can read your files, write real React, and open PRs while the result appears beside you. Everyone works from the same files in the same room. See who is doing what, then ship the same running product together. Spin one up for the UI, one for the tests, one for the copy. Watch them work in parallel, on the same canvas. Skip the status meetings; the work…from prototyper.co

Figr AIFeb 2026 · figr.design · ▲503Built Figr AI because I got tired of AI builder tools market themselves as design tools and end up skipping the hard part. Every tool I tried would jump straight to screens. But that's not how product design actually works. You don't just design screens. You think through the problem first. The flows, the edge cases, the user journey, where people will get stuck. Then the design comes finally. Figr does that thinking layer first. It parses your existing product via a chrome extension or takes in screen-records, then works through the problem with you before designing. Surfaces edge cases,…
Construct ComputerAug 2026 · construct.computer · ▲378We are building Construct Computer a cloud OS where autonomous AI agents ("Constructs") live and do your day to day work. You can observe them in real-time through a desktop OS frontend. The idea is agent-native infrastructure: instead of agents being API calls, they're persistent processes with their own compute, storage, and network identity. With integrations with a vast ecosystem of business tools, the Construct Agent can do anything from scheduling meetings, preparing documents, to deep researching the web, join meetings, and automate long running business operations with minimal human…
ProjektMar 2026 · getprojekt.com · ▲128I'm a product designer & front-end engineer who's been building with AI coding agents for the past year and working on teams launching AI products even longer. I always found the tools to be powerful, but the workflow around them lacking. I was constantly bouncing between terminals, browsers, file managers, and a rotating cast of IDEs. Nothing ever hit the right balance of simplicity and control. So, like any completely over-burdened dad and leader, I built my own. Projekt is an agent-agnostic workspace that consolidates everything into one place. Bring your own key, bring your own agent —…
AgentGridJul 2026 · agentgrid.sh · ▲77Hi HN, I’m Michael, I built AgentGrid with my friend Souren because we were tired of losing our coding sessions and couldn't keep track of what was actually being built across our many projects. Our approach was to use an infinite canvas desktop app for the TUIs we already know and love, mainly claude + codex. We drew inspiration from Figma and Railway. Overtime we added image nodes, notes, terminals, coding editors, source control, etc. I wasn't sure about it at first. It took me a month to give the first version Souren built a real try. What got me was an Apple System Update I've been…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
