CellCount is a browser-based cell-counting application for laboratories using hemocytometers or images from automated cell counters. It analyzes microscope-camera images and phone photos, detects the chamber grid, and counts live and dead cells using trypan blue exclusion. If the grid is not detected, users can place its crossings manually. Results include viability, dilution-adjusted cell concentration per milliliter, and a cell-size histogram. Detected cells are marked on the image for review; users can add or remove detections, change classifications, and approve the count. Shared protocols store dilution, square selection, sensitivity, and cell-size settings. Teams can keep dated sample records, export reports and image bundles, and verify accepted records with a SHA-256 digest. CellCount supports research and biotechnology labs working with cell lines, primary cells such as PBMCs, and yeast.

Webix Grid is a standalone JavaScript DataGrid component (table/grid UI widget) that is optimized for high-performance, large-dataset scenarios, and is designed to be dropped into web applications where tabular data needs to be displayed, edited, filtered, sorted, etc. Key positioning points: Lightweight: you don’t have to bring in the full Webix UI library if you only need the grid. Focused on “just the grid” use-case rather than a full UI framework. Feature-rich, offering a wide set of capabilities for enterprise-style data apps: - Virtual scrolling - Frozen columns - Inline editing - Sorting - Filtering - Grouping - Column resizing - Column reordering - Multi-line headers - Row selection - Cell selection - Copy/paste - Excel export - PDF export - CSV export - Paging - Validation - Undo/redo - Drag and drop - Spanning cells - Context menus - Keyboard navigation - Conditional formatting - Column summaries - Custom rendering - Live updates
