SDE Kit

A local-first SDLC desktop platform — manage your entire software development lifecycle completely offline, with zero cloud dependencies.

SDE-KIT is engineered as an enterprise-grade, privacy-centric workspace for solo developers to organize repositories, track tasks, manage milestones, take notes, compile code relations, and write software securely in a fully offline desktop environment.

Built with Rust + Tauri v2 + Svelte 5 (Runes) + Vanilla CSS Variables.

Key Enterprise Features

• 📂 Workspace Management — Open and index project folders with full file tree navigation and safe filesystem sandboxing constraints.
• 💻 Integrated Editor — High-speed, side-by-side editing utilizing CodeMirror 6 with local offline syntax highlighting extensions.
• ⊞ Virtual Kanban Board — Drag-and-drop task boards optimized via IntersectionObserver-based virtual scrolling for smooth rendering of large datasets.
• 🏁 Milestones Tracking — Align tasks to milestones and visually track completion percentages (via modular sub-components).
• 📝 Dedicated Local Notes — Standalone scratchpad note cards linked directly to local SQLite projects.
• 🕸 Relationship Graphs — Custom force-directed canvas layout engine written in Rust to visualize code relations.
• ⚡ Connection Pooling — Concurrent thread-safe database connection pooling utilizing r2d2 with Write-Ahead Logging (WAL journal) enabled.
• 🔄 Database Migrations — Managed schemas via version-controlled rusqlite_migration upgrades.
• 💾 Offline Local Export — One-click JSON and SQLite database exports generating direct object-URL downloads.
• 🚨 Unified Error & Loading UX — Universal exception handler translating backend Rust errors into visual glassmorphic overlays and floating Toast alerts.
• 🛡 CSP Sandboxing — Strict Content Security Policies and strict path verification guards (check_root_strict) to prevent unauthorized traversals.
