ctx is an Agentic Development Environment (ADE) that solves the proliferation problem every developer hitting multi-agent workflows faces: you want to run Claude Code on one task, Codex on another, and Cursor on a third — but you end up with three terminal windows, three context streams, and no unified way to review what any of them did. ctx provides one controlled surface for all of them, with containerized disk and network isolation, durable transcripts, and a merge queue system that keeps parallel worktrees from colliding. The security model is where ctx gets interesting for teams. Platform and security teams get a single controlled runtime instead of hoping developers are running agents responsibly. Agents operate with bounded autonomy rather than requiring constant approval — you set the disk and network controls upfront, then let them run. All tasks, sessions, diffs, and artifacts land in one review surface you can search and audit. Shown on Hacker News today and currently free with an open-source GitHub repository (github.com/ctxrs/ctx), ctx is positioning itself as the layer between developers and their AI agents — the place where you actually manage what the agents are doing rather than just talking to them one at a time. With 23 supported CLI agents including Claude Code, Codex, Hermes Agent, and Amp, it's already broad enough to be genuinely useful.

Pluck is a Chrome extension that solves one of the most common friction points in AI-assisted UI development: copying a design from an existing website. Instead of wrestling with raw HTML, you click any UI component — a nav bar, a card, a form, anything — and Pluck generates a clean, structured prompt optimized for Claude, Cursor, v0, or Bolt to recreate it. The extension strips noise from the DOM, restructures styling into clean CSS specifications, and can export directly to Figma. Crucially, it works on pages behind authentication — so you can capture your own app's components, competitor dashboards, or enterprise SaaS UIs without the usual copy-paste nightmare. Built by an indie developer using Plasmo and Next.js. Free tier covers 50 captures per month; unlimited use is $10/month. The "Pluck this" workflow — spot something, generate the prompt, build it — turns browsing into a design research tool. Surfaced on Hacker News Show HN today.
Reviewer scorecard
“The single review surface for multiple concurrent agents is the feature I didn't know I needed until I tried managing three Claude Code sessions by hand. Containerized disk isolation means I'm not scared of what the agents will do to my filesystem. Shipping immediately.”
“I do this workflow manually constantly — inspect element, copy classes, paste into Claude, iterate. Pluck automates the messy part. The authenticated-page support is the killer feature; most competitors only work on public sites. $10/month is genuinely cheap for the time it saves.”
“The 'supported agent' list will age fast as providers change their CLI interfaces. There's also real overhead in setting up containerized environments for every agent task — for simple use cases this is massive overkill. Worth watching, but the complexity cost is real.”
“AI coding tools already have screenshot-to-code features, and Claude can analyze HTML you paste directly. There's a real question of whether the generated prompts are actually better than just feeding Claude the raw HTML. Also, copying UI from competitor or third-party sites without permission sits in legally murky territory.”
“The IDE won wars by becoming the universal interface for developers. ctx is trying to do the same for agents — one environment that outlives any individual model or provider. If they execute well, this becomes the default way developers manage AI coding agents within 12 months.”
“Pluck represents an emerging category: tools that make the entire web a design asset library. As AI coding matures, the ability to rapidly prototype by remixing existing production UIs will become a standard developer skill. Early movers in this workflow will have a productivity edge.”
“Too engineering-focused to be relevant for most creative workflows right now. If it gains traction with developers, watch for a simpler abstraction layer that brings these capabilities to non-technical users.”
“As someone who regularly finds UI patterns I want to adapt, this changes everything. Browsing becomes active design research. The Figma export is the icing — capture from live production, land in your design file, build from there. The workflow finally makes sense end-to-end.”
