## Claude

Claude is Anthropic's flagship AI assistant, renowned among software engineers, writers, and enterprise analysts for its natural prose, low hallucination rates, and sustained agentic execution. While the legacy directory slug still references 2023's 'Claude 2', both the Claude 2 and Claude 3/3.5/3.7 generations have been fully retired. As of late 2026, claude.ai runs on the Claude 5.5 generation—led by Claude Opus 5.5 (released September 2026), Claude Sonnet 5.5 for rapid everyday tasks and coding, and Claude Haiku 5.5—supporting up to a 1-million-token context window, 128K output tokens, and adaptive extended thinking.

Inside the web, desktop, and mobile apps, Claude functions as a full production workspace rather than a simple chat box. Users organize persistent knowledge bases with custom instructions in Projects, render and edit live React applications, SVGs, mermaid diagrams, and formatted slide decks side-by-side in Artifacts, and connect external SaaS tools via the open Model Context Protocol (MCP) and native web search. Paid subscribers also gain access to Claude Code—Anthropic's terminal and IDE agent capable of autonomous multi-file engineering across entire codebases—and Claude Cowork for collaborative enterprise task execution.

Anthropic structures Claude's 2026 pricing around compute capacity and team governance. The Free tier offers daily access to Sonnet 5.5, while Claude Pro ($20/month or $17/month billed annually) unlocks Opus 5.5, extended thinking, Projects, and entry-level Claude Code access. Heavy individual builders can upgrade to Claude Max at $100/month (5x Pro capacity) or $200/month (20x Pro capacity), while organizations can mix Team Standard seats ($20/seat/month annual) and Team Premium seats ($100/seat/month annual with 5x capacity and full Claude Code access) or adopt usage-based Enterprise contracts with audit logs and SCIM.

**Pricing & Plans:** Free tier ($0); Claude Pro at $20/mo ($17/mo billed annually at $200/yr); Claude Max at $100/mo (5x Pro usage) or $200/mo (20x Pro usage); Team Standard at $25/seat/mo ($20/mo annual) and Team Premium at $125/seat/mo ($100/mo annual); Enterprise from $20/seat/mo + API usage.

- **Claude 5.5 Model Family & Adaptive Thinking:** Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
- **Claude Code & Claude Cowork Included on Paid Plans:** Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
- **Interactive Artifacts & Document Generation:** Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
- **Projects & Model Context Protocol (MCP):** Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.
- **Constitutional AI Safety & Enterprise Governance:** Trained on Anthropic's updated 2026 Constitution with strict privacy guarantees, SSO, SCIM provisioning, and HIPAA-ready healthcare configurations.

**Strengths:** Top-tier coding, bug-fixing, and agentic planning performance powered by Claude Opus 5.5 and Sonnet 5.5; Natural, nuanced writing style that avoids the repetitive clichés common in competing LLMs; Claude Max ($100/mo 5x and $200/mo 20x) and mixed Team Standard/Premium seats provide clear scaling for heavy Claude Code users; Open Model Context Protocol (MCP) ecosystem enables deep, standardized connections to local tools and enterprise data

**Limitations:** No native photorealistic image or video generation inside claude.ai (limited to SVGs, code charts, and diagrams); Free tier does not include Claude Code and hits 5-hour rolling message limits quickly during long-context chats; Pro users ($20/mo) who rely heavily on Opus 5.5 or Claude Code can still exhaust their 5-hour rolling window and require Max ($100/mo)

## OpenSilver

OpenSilver rebuilds the Microsoft Silverlight and WPF programming model on top of .NET and WebAssembly, so a codebase written in C#, VB or F# with XAML keeps working in Chrome, Firefox, Safari, Windows, macOS and Android. Teams that own a legacy Silverlight line-of-business application — or a Windows-only WPF desktop app — can move it to the browser while reusing over 95% of the original source, keeping screens visually identical so no user retraining or documentation rewrite is needed.

The framework ships with enterprise-oriented controls and library compatibility, including RIA Services and LightSwitch support, and the 3.3 release introduced an AI-enhanced drag-and-drop UI designer, the ability to host Blazor components directly inside XAML applications, and MAUI Hybrid integration. It also interoperates with Blazor, React and Angular when a team wants to mix stacks rather than migrate everything at once.

The core technology stack is free under the MIT license and can be downloaded as an SDK or tried instantly in the zero-setup XAML.io online IDE. For organizations that prefer not to run the migration themselves, Userware offers a commercial end-to-end migration service, support plans and pro services — which is where the paid side of the offering sits.

**Pricing & Plans:** The OpenSilver framework itself is free and open source under the MIT license, including the SDK and the online XAML.io IDE. Paid options come through Userware: commercial support plan subscriptions, pro services, and end-to-end WPF/Silverlight migration engagements quoted per project.

- **95%+ code reuse for legacy apps:** Recompile existing Silverlight or WPF C#, VB and F# code into a WebAssembly app that runs in any modern browser, avoiding a costly rewrite.
- **AI-enhanced visual designer:** OpenSilver 3.3 adds an AI-assisted drag-and-drop UI designer for building and editing XAML screens faster.
- **Blazor and MAUI interop:** Host Blazor components directly inside XAML applications and integrate with MAUI Hybrid, plus mix in React or Angular where useful.
- **Enterprise library compatibility:** Keeps support for RIA Services, LightSwitch and common third-party controls so established business apps keep working.
- **Zero-setup online IDE:** Try the framework immediately in the browser at XAML.io with no install and no signup, or download the SDK locally.

**Strengths:** Reuses the large majority of existing Silverlight/WPF code and preserves the pixel-level UI; Open-source MIT core with an installable SDK and a free in-browser IDE; Professional migration services and support plans available when you need them; Broad target coverage: all major browsers plus Windows, macOS and Android

**Limitations:** Targeted at teams with legacy .NET code rather than greenfield developers; Enterprise-grade migration and support are commercial and quoted per project; WebAssembly output can still be heavier than a hand-written modern front-end
