PsyChonek

PsyChonek is an independent, open-source publisher whose single public offering, SQL Plan For Dummies, distills the opaque art of database performance tuning into a lightweight, interactive desktop utility. Written in Rust with the Tauri framework and paired with Vue and D3.js for reactive visuals, the program ingests raw SQL execution plans—whether harvested from SQL Server, PostgreSQL, MySQL or SQLite—and renders them as navigable, color-coded trees whose thickness and hue instantly flag the costliest operators. Developers and DBAs can click any node to reveal predicate details, I/O statistics and time splits, while an integrated search bar filters plans by table, index or hint. Animated transitions make it easy to watch how rewriting a query or adding an index collapses subtree costs in real time, turning tuning sessions into exploratory workshops instead of monochrome text archaeology. The viewer also exports annotated PNG or SVG diagrams for documentation and can side-load multiple plans for A/B comparison, a workflow prized by consultants who need to justify index changes to stakeholders. Because the entire package is self-contained, it runs offline on any modern Windows workstation without administrative rights, making it a discreet companion for production incidents or classroom demos alike. PsyChonek’s SQL Plan For Dummies is available for free on get.nero.com, delivered through trusted Windows package sources such as winget, always installing the latest build and supporting batch installation alongside other utilities.
