TypeScript
TypeScript
TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.Starting Price: Free -

JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities. -

Convex's libraries maintain real-time synchronization between the frontend, backend, and database state without the need for manual state management, cache invalidation, or WebSockets. It includes built-in support for cloud functions, scheduling, authentication, file storage, and a variety of components that can be added with a simple npm i command. Developers can define their entire backend, including database schemas, queries, and APIs, in code, which is typechecked and autocompleted, and can be generated by AI with high accuracy. Convex's architecture ensures that all transactions are serializable, providing strong consistency guarantees and eliminating race conditions.Starting Price: $25 per month -

WPKG
WPKG
WPKG is an automated software deployment, upgrade, and removal program for Windows. It can be used to push/pull software packages, such as Service Packs, hotfixes, or program installations from a central server (for example, Samba or Active Directory) to a number of workstations. It can run as a service to install the software in the background (silent install), without user interaction. It can install MSI, InstallShield, PackagefortheWeb, Inno Setup, Nullsoft, other software installers or .exe packages, .bat and .cmd scripts, and similar, no more repackaging to perform software installation. WPKG is open-source software. WPKG can add great value to your Samba or Active Directory setup, as it allows you to perform software installation, updates, removal, etc. on your workstations. It is also possible to execute custom scripts on your workstations, like synchronizing time, setting printers, changing permissions, or adding registry entries.Starting Price: Free -

NSwag
Rico Suter
NSwag is a comprehensive Swagger/OpenAPI 2.0 and 3.0 toolchain for .NET, .NET Core, ASP.NET Core, and TypeScript, written in C#. It enables developers to generate OpenAPI specifications from existing API controllers and create client code from these specifications. NSwag combines functionalities similar to Swashbuckle (for OpenAPI/Swagger generation) and AutoRest (for client generation) into a single toolchain, eliminating the need for both. Key features include the ability to generate Swagger 2.0 and OpenAPI 3.0 specifications from C# ASP.NET (Core) controllers, serve these specifications via ASP.NET (Core) middleware with integrated Swagger UI or ReDoc, and generate C# or TypeScript clients/proxies from the specifications. NSwag offers multiple usage methods, including a user-friendly Windows GUI (NSwagStudio), command-line interfaces compatible with Windows, Mac, and Linux, and integration into C# code via NuGet packages.Starting Price: Free -

AutoRest
Microsoft
The AutoRest tool generates client libraries for accessing RESTful web services. Input to AutoRest is a spec that describes the REST API using the OpenAPI specification format and streamlines the creation of client code across multiple programming languages, including C#, Java, Python, TypeScript, and Go. This automation enhances consistency and efficiency in API consumption, reducing the manual effort required to develop and maintain client libraries. AutoRest operates through a flexible pipeline that processes OpenAPI input files, transforming them into a code model which is then utilized by language-specific generators to produce client code adhering to each language's design guidelines. The tool supports both OpenAPI 2.0 and 3.0 specifications, ensuring compatibility with a wide range of APIs. Developers can install AutoRest on Windows, macOS, or Linux systems, with installation facilitated via Node.js.Starting Price: Free -
