About

A TypeScript-like language for WebAssembly. AssemblyScript targets WebAssembly's feature set specifically, giving developers low-level control over their code. Its similarity with TypeScript makes it easy to compile to WebAssembly without learning a new language. Integrates with the existing Web ecosystem - no heavy toolchains to set up. Simply npm install it! AssemblyScript is free and open source software released under the Apache License, Version 2.0, builds upon Binaryen and is based on the WebAssembly specification. It is brought to you by the following awesome people:

About

GridCraft is an open-source spreadsheet application for creating, editing, calculating, and analyzing workbooks on desktop or in a browser. Its interface includes a ribbon, formula bar, and sheet tabs, with tools for formulas, dynamic arrays, tables, sorting, filtering, data validation, conditional formatting, charts, and PivotTables. It supports XLSX, CSV, and TSV workbooks, with comments, hyperlinks, print settings, and PDF output. Users can build budgets, schedules, sales summaries, and other data tables, then calculate and visualize results in a workbook. Desktop releases are available for Windows, macOS, and Linux; a WebAssembly build can be hosted on a static server. A command-line tool, JSON control channel, and Model Context Protocol server let developers and AI agents inspect, edit, calculate, and format workbooks programmatically. GridCraft is free, open-source software, and its maintainers currently describe the project as pre-alpha.
