Dirac is an open-source AI coding agent built by Dirac Delta Labs that shot to the top of TerminalBench-2 with a 65.2% score using Gemini Flash — while costing 64.8% less than competing agents. Forked from Cline and rebuilt with a performance-first architecture, it handles file modifications, multi-file refactoring, terminal commands, and browser automation through an approval-based workflow. What sets Dirac apart is its technical substrate: hash-anchored edits replace fragile line-number targeting with stable content hashes, AST-native processing understands language structure for TypeScript, Python, and C++, and multi-file batching reduces LLM roundtrips by processing several files per call. The result is a leaner context that preserves model reasoning quality without burning through tokens. Available as both a VS Code extension and an npm CLI, Dirac supports Anthropic, OpenAI, Google, Groq, and Mistral as backends. Its Apache 2.0 license and strong TerminalBench showing on the affordable Gemini Flash model make it a compelling pick for developers who want production-grade coding assistance without the per-token bill shock.

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
“Topping TerminalBench-2 while being 64.8% cheaper is the kind of benchmark that actually matters to developers. The hash-anchored editing and AST-native approach fix the two most annoying failure modes of existing coding agents — wrong line edits and syntax-blind refactors.”
“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.”
“It's a Cline fork with smart optimizations — not a ground-up rethink. TerminalBench-2 scores are reproducible only if you're running similar tasks; complex real-world codebases may tell a different story. Also, requiring your own API key still means real money.”
“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 race to build the cheapest, most accurate coding agent is the real infrastructure play of 2026. Dirac's multi-provider support and lean context model are exactly the primitives that make agentic coding deployable at scale — not just on powerful machines.”
“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.”
“The VS Code extension makes it approachable for designers who code. Approval-based workflows mean it won't silently rewrite your carefully named CSS classes. Worth trying if you've been burned by agents that act first and apologize later.”
“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.”
