Amazon EKS Pod Identity Webhook
Amazon EKS Pod Identity Webhook
This webhook is for mutating pods that will require AWS IAM access. After version v0.3.0, --in-cluster=true no longer works and is deprecated. Please use --in-cluster=false and manage the cluster certificate with a cert-manager or some other external certificate provisioning system. This is because certificates using the legacy-unknown signer are no longer signed when using the v1 certificates API. Create an OIDC provider in IAM for your cluster. You can find the OIDC discovery endpoint by describing your EKS cluster. Create an IAM role for your pods and modify the trust policy to allow your pod's service account to use the role. All new pod pods launched using this Service Account will be modified to use IAM for pods. Below is an example pod spec with the environment variables and volume fields added by the webhook. To ensure workloads are scheduled on windows nodes have the right environment variables, they must have a nodeSelector targeting windows it must run on. -

Lighthouse
Automated auditing, performance metrics, & best practices for the web
Lighthouse is an open-source, automated tool that analyzes and audits web apps and web pages in order to improve their quality. Lighthouse collects modern performance metrics and insights on developer best practices; auditing for performance, accessibility, SEO and more. After auditing it produces a report either in JSON or HTML. Included in the report is a reference doc that explains the importance of the audit and how to fix the problem areas, which you can use to improve the web app or web page. Lighthouse can be integrated directly into the Chrome DevTools with its own panel. To run it, you would simply have to select the Lighthouse panel and click on "Generate report". It can also be run from the command line, or as a Node module. -

Web Archives
Browser extension for viewing archived and cached versions of websites
Browser extension for viewing archived and cached versions of web pages, available for Chrome, Edge and Safari. Web Archives is a browser extension that enables you to find archived and cached versions of web pages, and comes with support for more than 10 search engines. Searches can be initiated from the context menu and the browser toolbar. A diverse set of archive and cache sources are supported, which can be toggled and reordered from the extension's options. Visit the wiki for the full list of supported search engines. You may choose to allow the extension to run on every website, or grant access to the current website before a search. When you grant access only to the current website, access must also be granted to each search engine in order to view search results. A handful of search modes are offered that serve different use cases. The search mode can be set independently for the context menu and the browser toolbar from the extension's options. -

Zeep
A Python SOAP client
A fast and modern Python SOAP client. Compatible with Python 3.7, 3.8, 3.9, 3.10, 3.11, and PyPy. Build on top of lxml and requests. Support for Soap 1.1, Soap 1.2 and HTTP bindings. Support for WS-Addressing headers. Support for WSSE (UserNameToken / x.509 signing) Support for asyncio via httpx. Experimental support for XOP messages. Zeep inspects the WSDL document and generates the corresponding code to use the services and types in the document. This provides an easy-to-use programmatic interface to a SOAP server. Parsing the XML documents is done by using the lxml library. This is the most performant and compliant Python XML library currently available. This results in major speed benefits when processing large SOAP responses. The SOAP specifications are unfortunately really vague and leave a lot of things open for interpretation. -

Nomulus
Top-level domain name registry service on Google Cloud Platform
Nomulus is a production-grade, open-source domain registry platform used to operate top-level domains (TLDs). It implements the core registry protocols—EPP for registrar interactions, WHOIS/RDAP for public data access—and manages the lifecycle of domain objects, hosts, and contacts. The system is built to scale and to enforce policy: pricing rules, reserved names, premium tiers, grace periods, and automated renewals are modeled explicitly. It integrates with DNS provisioning, data escrow, and billing so you can run a compliant registry end-to-end rather than stitching together separate services. Operators get admin tools for reporting, manual adjustments, and policy configuration, while registrars interact through standards-compliant channels. Nomulus treats registries as serious infrastructure: audited flows, durable storage, and clear extension points for custom policies and TLD-specific behavior. -

Apache Guacamole
HTML5 Clientless Remote Desktop
Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH. We call it clientless because no plugins or client software are required. Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser. -

Polka
A micro web server so fast, it'll make you dance
Polka is a micro web server for Node.js that positions itself as an extremely minimal yet highly performant alternative to Express. Under the hood it is essentially a thin layer on top of Node’s native HTTP server, adding just enough routing, middleware, and sub-application support to be productive without the weight of a full framework. Its API is intentionally similar to Express, which makes it easy for existing Express users to migrate or share middleware with minimal changes. Because it focuses on speed and small size, polka can be attractive for performance-sensitive services, serverless functions, or applications where dependency budgets are tight. The project exposes common features like route parameters, query parsing (usually via external middleware), and simple error handling, but leaves more advanced concerns to the user or ecosystem packages. -

SWC
Rust-based platform for the Web
SWC is an extensible Rust-based platform for the next generation of fast developer tools. It's used by tools like Next.js, Parcel, and Deno, as well as companies like Vercel, ByteDance, Tencent, Shopify, and more. SWC can be used for both compilation and bundling. For compilation, it takes JavaScript / TypeScript files using modern JavaScript features and outputs valid code that is supported by all major browsers. SWC is 20x faster than Babel on a single thread and 70x faster on four cores. SWC can be downloaded and used as a pre-built binary, or built from the source. SWC (stands for Speedy Web Compiler) is a super-fast TypeScript / JavaScript compiler written in Rust. It's a library for Rust and JavaScript at the same time. If you are using SWC from Rust, see rustdoc and for most users, your entry point for using the library will be parser. If you are using SWC from JavaScript, please refer to the docs on the website. -

freegeoip
IP geolocation web server
Launched more than 6 years ago, the freegeoip.net API has grown into one of the biggest and most widely used APIs for IP to location services worldwide. The API is used by thousands of developers, SMBs and large corporations around the globe and is currently handling more than 2 billion requests per day. After years of operation and the API remaining almost unchanged, today we announce the complete re-launch of freegeoip into a faster, more advanced and more scalable API service called ipstack. All users that wish to continue using our IP to location service will be required to sign up to obtain a free API access key and perform a few simple changes to their integration. While the new API offers the ability to return data in the same structure as the old freegeoip API, the new API structure offers various options of delivering much more advanced data for IP Addresses. -
