Features and specs

What each product offers, as listed by its team.

Agenta.ai 5 features
ShellNewHandler 0 features
  • Open-Source and Self-Hostable
    Agenta.ai is open-source, allowing teams to self-host the platform on their own infrastructure. This provides greater control over data privacy, security, and customization, which is particularly important for enterprise users handling sensitive data.
  • End-to-End LLM Development Platform
    Agenta provides a comprehensive workflow for building, testing, evaluating, and deploying LLM-powered applications. It covers prompt engineering, experimentation, evaluation, and observability in a single platform, reducing the need to stitch together multiple tools.
  • Framework and Model Agnostic
    Agenta is designed to work with any LLM model, framework, or library. Developers are not locked into a specific tech stack and can use LangChain, LlamaIndex, custom Python code, or any other tooling alongside the platform.
  • Built-in Evaluation and Testing Tools
    The platform offers robust evaluation capabilities including human evaluation, automatic evaluators, and A/B testing. Users can create test sets, run systematic evaluations, and compare different prompt variants or model configurations side by side.
  • Collaborative Prompt Engineering Playground
    Agenta features an interactive playground that enables both technical and non-technical team members to experiment with prompts, adjust parameters, and iterate on LLM application configurations without needing to write code, fostering better collaboration between developers and domain experts.

Possible disadvantages

  • Relatively Young Ecosystem
    Agenta.ai is a relatively newer entrant in the LLMOps space, which means its community, third-party integrations, and ecosystem are still maturing compared to more established platforms. Users may encounter fewer community resources and tutorials.
  • Learning Curve for Full Feature Utilization
    While the playground is user-friendly, leveraging the full platform — including custom evaluators, deployment pipelines, and observability features — can require significant setup and onboarding time, especially for teams unfamiliar with LLMOps workflows.
  • Limited Enterprise Features in Open-Source Version
    Some advanced features such as role-based access control, advanced analytics, and enterprise-grade support may be limited or unavailable in the free open-source version, pushing organizations toward paid plans for production-grade usage.
  • Self-Hosting Complexity
    While self-hosting provides data control, setting up and maintaining the platform on your own infrastructure can be complex, requiring DevOps expertise and ongoing maintenance for updates, scaling, and troubleshooting.
  • Smaller Community Compared to Competitors
    Compared to rival platforms like LangSmith or Weights & Biases, Agenta has a smaller user community. This can mean fewer shared templates, community-contributed evaluators, and less peer support when troubleshooting issues.

Overall verdict

  • Agenta.ai is a solid open-source LLMOps platform that streamlines prompt engineering, evaluation, and observability for teams building LLM applications, making it a good choice for developers and organizations who want an integrated, self-hostable alternative to piecing together multiple tools.

Why this product is good

  • Offers an all-in-one platform for prompt management, versioning, and testing without needing separate tools
  • Open-source with self-hosting options, giving teams full control over data privacy and infrastructure
  • Supports side-by-side comparison of prompts and models to quickly identify the best-performing configurations
  • Provides built-in evaluation pipelines including human feedback and automated metrics
  • Includes observability and tracing features to monitor LLM app performance in production
  • Integrates with popular frameworks and model providers, reducing vendor lock-in
  • Collaborative interface allows both technical and non-technical team members to iterate on prompts

Recommended for

  • Engineering teams building and iterating on LLM-powered applications
  • Organizations that require self-hosted or on-premise LLMOps solutions for compliance or security reasons
  • Product teams needing collaboration between developers and prompt engineers or subject matter experts
  • Startups and enterprises looking to systematically evaluate and compare different prompts or models
  • Teams wanting observability and debugging tools for LLM applications already in production

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

  • Ask HN: What's your current AI agentic setup?
    I have two Claude subscriptions and a ChatGPT subscription + Openrouter (mainly deepseek) I mainly use Agenta ( https://github.com/agenta-ai/agenta or https://agenta.ai ) as my main setup [disclaimer I am the founder]. It allows me to: -... - Source: Hacker News / 4 days ago
  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
