Sunder is an open-source desktop app where tools are installed as packages.A package can add a panel, dashboard, command, automation, integration, AI agent, file utility, hardware control, or local workflow inside Sunder.Instead of installing a separate app for every small tool, you install packages into one desktop app.Examples of what a Sunder package could be: - A dashboard for your server, game server, shop, invoices, or internal API - A file tool that watches folders, renames files, resizes images, or organizes downloads - A button that runs a backup script, import job, deploy command, or local workflow - A panel for Home Assistant, a 3D printer, local device, lab tool, or custom hardware - An AI workspace that can use files, shell commands, web tools, MCP, memory, local models, and package-building toolsSunder is not a window manager. It does not arrange random app windows or embed existing apps. Packages are built for Sunder and run inside Sunder.The important part is Agent Builder.With Sunder Agent Builder, you can create a new package inside Sunder and ask Agent Chat to build it. The agent can create files, edit code, run commands, inspect errors, test builds, and keep iterating.That means non-developers and vibecoders can start building useful native desktop tools without manually setting up a full desktop development environment first.For developers, Sunder provides the boring app infrastructure:- Desktop host - Package lifecycle - Install, update, enable, disable, uninstall - Settings and secrets - Local storage and logs - SDK contracts - Package validation - Registry publishing - Cross-platform shell for Windows, macOS, and LinuxYou build the tool. Sunder provides the app around it.

Copyber is a modern clipboard manager designed for people who work across tools, platforms, and tabs all day long. Whether you're a developer, designer, writer, marketer, or just someone who copies a lot of stuff. Copyber helps you keep everything organized, accessible, and ready to use.Built for desktop (Windows, macOS, Linux), Copyber offers a fast, clean, and privacy-first experience — no account required.<h3>⚡ Why Copyber?</h3>Let’s face it, most clipboard managers feel like relics. Outdated design, clunky interfaces, unreliable syncing, or bloated with features you don’t need. Copyber was built out of frustration with that experience.It's a utility app that focuses on what actually matters:<ul><li>Keeping a searchable history of what you copied</li><li>Helping you organize it with context-aware features</li><li>Working fast and clean, without needing an account</li><li>Staying local-first for privacy and performance</li></ul><h3>🔑 Key Features</h3><ul><li>Instant Search Search your clipboard history in milliseconds. Full-text search with filters, tags, and smart sorting.</li><li>Spaces (Coming Soon) Organize your clipboard into contextual "Spaces" — personal, work, project-based — so you can quickly access only what matters right now.</li><li>Smart Previews See rich previews for URLs, files, images, and structured text. No need to open tabs or guess from filenames.</li><li>Visual Recognition Automatically detects content types like links, code snippets, file paths, emails, and more.</li><li>Local-First by Default All core functionality works without an account. No cloud dependency unless you want it.</li><li>AI-Powered Workflows (Coming Soon) Copyber is built to evolve into a real productivity assistant. By passively organizing your clipboard, it prepares rich data for on-demand AI use — imagine asking, "Summarize my research," and Copyber knows exactly what you mean.</li><li>Secure Sync (Coming Soon) Future versions will support cross-device sync with full end-to-end encryption. You’ll be able to copy on one device and paste on another — without compromising privacy.</li></ul><h3>💻 Built With</h3>Copyber is built using .NET with Avalonia UI for full cross-platform native performance. It’s designed to feel like a true desktop app, not a clunky wrapper. The backend is modular and built with extensibility and AI integration in mind.<h3>🔒 Privacy-First, By Design</h3>Copyber stores your clipboard locally. Nothing is sent to a server unless you explicitly opt into future sync features. Even then, your data will be encrypted end-to-end.This makes Copyber ideal for developers, writers, designers, and anyone working with sensitive or high-value data. It's the clipboard manager you can trust to stay out of your way — until you need it.<h3>🚀 Roadmap Highlights</h3>✅ Core features: history, search, labeling 🔜 Spaces for better organization 🔜 AI for contextual automation 🔜 Secure cross-device sync 🔜 Plugins and API integrations<h3>🌐 Use Cases</h3><ul><li>Quickly find that SQL query or regex pattern you copied 4 hours ago</li><li>Save code snippets or templates you reuse often</li><li>Organize research into Spaces and come back to it anytime</li><li>Use it as a staging tool for posting, emailing, or summarizing</li><li>Later: Connect Copyber with your AI assistant for instant context-driven output</li></ul><h3>💬 Why I Built It</h3>Like many developers, I switch between macOS and Windows regularly. And I was shocked how hard it was to find a clipboard manager that looked good, worked consistently, and respected my data — especially across devices.So I built Copyber out of necessity. But as I developed it, I realized the clipboard is one of the most overlooked UX touchpoints in modern computing. It sits at the center of almost everything — writing, coding, designing, researching — yet it's still treated like a single-slot memory buffer.Copyber is my attempt to modernize that layer and make it actually helpful.<h3>🧠 A Sneak Peek at the AI Layer</h3>Most AI tools require you to “feed” them information first. But Copyber already has your recent knowledge — links, notes, questions, ideas — passively captured as you work.In the future, this will unlock workflows like:<ul><li>"Summarize everything I copied today"</li><li>"Generate an email reply based on this draft + link"</li><li>"Group everything related to project X and turn it into a doc"</li></ul>No prompting, no searching — just intelligent, context-aware utility.<h3>🎯 Who Copyber Is For</h3><ul><li>Developers who live inside terminals, editors, and browsers</li><li>Writers or researchers constantly gathering content</li><li>Productivity nerds with 20+ open tabs</li><li>Anyone tired of copying something useful… and losing it five minutes later</li></ul>
