Clide is a native macOS terminal app that rethinks the terminal experience for the agent era. Instead of bolting AI onto an existing terminal, Clide builds around it: an AI pair-developer lives in a side panel alongside a customizable grid of up to 6×6 terminal panes. The AI can read terminal scrollback, preview files, and execute commands into any pane—with user confirmation—making it a genuine collaborator rather than a glorified autocomplete. Built with SwiftTerm, AppKit, and SwiftUI (explicitly not Electron), Clide is genuinely native—fast, memory-efficient, and system-integrated. Drag files from Finder into the AI chat, use the screenshot HUD to share visual context, speak commands via voice input, and rely on workspace memory that persists across sessions. Zero telemetry. Free. What separates Clide from tools like Claude Code or Cursor is its terminal-centric model: rather than AI owning the editor and calling a shell, Clide keeps the shell primary and lets the AI reach into it. For server-side developers, sysadmins, and anyone who actually lives in a terminal, this architecture is more natural and less footprint-heavy than spinning up a full IDE for AI assistance.

Rubber Duck
A second AI model reviews your Copilot agent's plan before it ships code

Rubber Duck is a new capability in the GitHub Copilot CLI agent workflow that introduces cross-model code review. When Copilot's primary agent generates a plan or implementation, Rubber Duck routes that output to a second AI model from a different provider family for an independent review — catching architectural mistakes, edge cases, and logic errors before any code is committed. The name is a nod to rubber duck debugging, but the mechanism is more like adversarial collaboration: the reviewing model has no stake in the primary model's plan and no context about why certain decisions were made. It approaches the output fresh, which is precisely where different models excel — a model that didn't generate a plan is much better at finding its flaws than the model that created it. This is a meaningful shift in how AI-assisted development works. Most AI coding tools use a single model throughout the entire workflow. Rubber Duck introduces model diversity as a quality-control mechanism, acknowledging that no single AI has perfect judgment and that cross-checking is standard practice in human code review for good reason. It's available now as part of GitHub Copilot CLI.
Reviewer scorecard
“Clide nails the architecture: terminal-first, AI as assistant rather than owner. The native SwiftUI build means it's fast and doesn't eat 4GB of RAM like Electron alternatives. Grid panes plus agent control is exactly what I want for complex multi-process debugging sessions.”
“The insight here is sharp: models are worst at finding their own mistakes. Using a second model as an independent reviewer is the right call, and it mirrors how good human code review actually works. I want to know which model pairs GitHub is using — the quality of the adversarial check will depend heavily on choosing models with genuinely different failure modes.”
“Day-one Product Hunt launch with 11 followers means this is extremely unproven. The grid + AI concept is compelling but implementation bugs in a terminal app can destroy your work. Wait for a few months of community testing before trusting it with production servers.”
“This doubles your inference cost for every agentic operation, and GitHub hasn't published latency numbers. If the cross-model review adds 10-15 seconds to every agent step, it'll be disabled by most developers within a week. Catch rates vs. latency overhead is the key tradeoff and it hasn't been benchmarked publicly yet.”
“The terminal isn't going away—it's getting AI co-pilots. Clide represents a category of tools that meet systems developers where they already work rather than pulling them into new IDEs. Native, agentic, terminal-first: this is what the shell looks like in 2026.”
“Model ensembling for quality control is the obvious next step in agentic AI workflows, and GitHub shipping it in Copilot normalizes the pattern. In two years, single-model agent pipelines will feel as naive as shipping code without CI. Rubber Duck is the CI layer for agentic code generation.”
“Voice input, drag-and-drop files, screenshot sharing into the AI context—Clide is thoughtfully designed for humans who actually use terminals. The grid layout alone would make it worth trying. Free with zero telemetry is a bonus.”
“Honestly, I'd love this for writing. Having a second AI with a completely different perspective review a draft before it goes out catches things the primary model is blind to — that's just good editing practice. The name 'Rubber Duck' is perfectly chosen; it captures the spirit of the feature better than any technical description could.”
