    Lighthouse

    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.

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".

    Site Kit for WordPress

    Site Kit for WordPress

    Site Kit is a one-stop solution for WordPress users

    Site Kit is a first-party WordPress plugin that brings key Google services into a single dashboard so site owners can see how their content performs and fix issues without leaving wp-admin. After a guided setup and verification flow, it connects properties to Search Console, Analytics, AdSense, PageSpeed Insights, and other services, surfacing the most relevant metrics per page and per site. The plugin focuses on clarity: traffic sources, search queries, top pages, and monetization signals appear alongside actionable performance recommendations. It also handles authentication and permission scopes securely, so multiple collaborators can access insights without sharing credentials. Widgets and contextual panels put data where it’s needed—for example, on the post list or edit screen—reducing tab-switching. For developers and agencies, Site Kit simplifies client onboarding and standardizes reporting across many sites.

    Fenix Web Server

    Fenix Web Server

    A simple and visual static web server with collaboration features

    Fenix is a desktop-based static web server application built for developers who want a quick, visual, and easy way to serve local folders as HTTP servers — useful for previewing static sites, mocking APIs, or sharing directories without requiring heavy web server setup. It provides a GUI that lets you point to a local directory, pick a port (or auto-choose an available port), and start a server with a single click; this makes it a handy tool for front-end developers, static-site creators, or anyone needing a fast local web server. Beyond just serving static files, Fenix supports features like automatic port management, optional GZip compression, optional JS/CSS minification, Markdown-to-HTML rendering, and simple server logging — making it more capable than the most minimal style tools. The app can also share your local site publicly (for example via tunnelling) — useful for quick demos, sharing prototypes, or collaborating with remote reviewers.

    Based on HL7 v.2.3.1 Orders & Results Reference Information Model (RIM)s, The project is NOT a CPOE per-se. Instead, the project provides "applications" that allow EHR's to perform Outpatient Orders and Results via HIE, and collect these into their EHRs to feed the EHR "CPOE module / section" (ex. with prescribed drugs, ordered labs and results, ....) The first module in the project was the "ePrescribing application"; certified by RxHub and SureScripts back in 2007. New implementation needs to "re-certify" with SureScripts (which should not be much of a problem) Work on eLabs (using ELINCS, LOINC etc.) is being considered as participants join the project become available. The HL7 RIM allows for eImaging applications, eConsults applications, eReferrals applications, etc. Applications work independently, but through HIE, results come back to the provider to see it in its "CPOE Section or Module" Requires licensing of the MediSpan Drug Database for ePrescrib

    AST explorer

    AST explorer

    A web tool to explore the ASTs generated by various parsers

    Paste or drop code into the editor and inspect the generated AST. Depending on the parser settings, it not only supports ES5/CSS3. Since the future syntax is supported, the AST explorer is a useful tool for developers who want to create AST transforms. In fact, transformers are included so you can prototype your own plugins. Save and fork code snippets. Copy the URL to share them. Copying an AST or dropping a file containing an AST into the window will parse the AST and update the code using escodegen. Otherwise, the content of the text editor will be replaced with the content of the file (i.e. you can drag and drop JS files). Choose between multiple parsers and configure them. shift+click on a node expands the full subtree. Hovering over a node highlights the corresponding text in the source code. Editing the source or moving the cursor around will automatically highlight the corresponding AST node (or its ancestors of it isn't expanded).
