JackHamr is the AI coding agent that ships software end-to-end. Instead of a single assistant that tries to do everything, it runs a team of specialist agents โ€” one writes the spec, another plans the implementation, others build, test, review, and ship the code. Each agent has its own role, tools, and personality.

Agents run on hosted cloud dev environments with VS Code, Docker, SSH access, and WireGuard-encrypted networking. Close your laptop and they keep working. Talk to them with push-to-talk voice chat or type naturally. GitHub is built in โ€” one-click clone, automatic branch-per-task, real-time commit sync, and PR creation.

Bring your own LLM keys (OpenAI, Anthropic, Google, or self-hosted) or use ours at cost โ€” swap models mid-pipeline to use the best model for each task. Build custom orchestration pipelines and agent skills. Share agents across your organization.

Pay-as-you-go with fully itemized billing โ€” infrastructure at cost, LLM tokens with zero markup. $10 free credit to start, no card required.

Opa features and specs

  • Full-Stack Development
    Opa is designed to be a full-stack language, which means it can handle both the client-side and server-side development within a single codebase. This reduces the need for context switching between multiple programming languages and can simplify the development process.
  • Security Features
    Opa includes built-in security features such as automatic data validation and prevention of common web vulnerabilities like XSS and SQL injection, potentially reducing the number of security issues in web applications.
  • Concurrency Support
    Opa natively supports asynchronous programming and concurrency, allowing developers to write efficient, non-blocking code without needing additional frameworks or libraries.
  • Integrated Web Development
    The language integrates multiple aspects of web development such as database, server, and client interactions, aiming to streamline the process and reduce the complexity of managing disparate technologies.

Possible disadvantages of Opa

  • Limited Adoption
    Opa is not widely adopted, which can result in a smaller community and fewer resources, tutorials, or third-party libraries compared to more popular web development languages and frameworks.
  • Learning Curve
    Developers new to Opa might face a steep learning curve due to its unique approach and syntax, which differs considerably from more traditional web development languages.
  • Tooling and Ecosystem
    The tooling and ecosystem around Opa may not be as mature or robust as those surrounding other more established languages, potentially leading to challenges in finding compatible tools or plugins.
  • Performance Overheads
    While Opa abstracts many details for developers, this abstraction can introduce performance overheads compared to languages that allow more fine-tuned control over performance optimizations.

JackHamr features and specs

  • AI-Powered Music Creation
    JackHamr leverages artificial intelligence to assist users in creating music, making the composition process more accessible and efficient for both beginners and experienced musicians.
  • Streamlined Workflow
    The platform aims to simplify the music production workflow by integrating AI tools that can help with various aspects of music creation, from melody generation to arrangement suggestions.
  • Accessibility for Non-Musicians
    By using AI assistance, JackHamr can lower the barrier to entry for people who want to create music but may lack formal training or extensive knowledge of music theory.
  • Creative Inspiration Tool
    JackHamr can serve as a powerful brainstorming and inspiration tool, helping artists overcome creative blocks by generating ideas and musical elements they might not have considered.
  • Emerging Technology Platform
    As an AI music platform, JackHamr is positioned in a growing and innovative space, potentially offering cutting-edge features as AI music technology continues to advance rapidly.

  • Ask HN: Abandoned/dead projects you think died before their time and why?
    Definitely Opa: http://opalang.org/ In 2011, before TypeScript, Next.js or even React, they had seamless server-client code, in a strongly typed functional language with support for features like JSX-like inline HTML, async/await, string interpolation, built-in MongoDB ORM, CSS-in-JS, and many syntax features that were added to ECMAScript since then. I find it wild how this project was 90%+ correct on how we will... - Source: Hacker News / 9 months ago
  • Ask HN: Abandoned/dead projects you think died before their time and why?
    Opa language 2012, it was a typed nextjs before its time. http://opalang.org/ I think the market was still skeptical about nodejs on the server at the time but other than that I donโ€™t really know why it didnโ€™t take off. - Source: Hacker News / 9 months ago

    A tool to solve optimization problems using quantum computers. Just released the first open-source version https://github.com/pasqal-io/maximum-independent-set/. We'll see if I have the energy to work on that. - Source: Hacker News / 12 months ago
  • Imba โ€“ The friendly full-stack language
    I remember Opa http://opalang.org/ tried something similar at the time when MongoDB was new and modern. - Source: Hacker News / almost 3 years ago
  • Ask HN: What web frameworks/technologies did not succeed as per your expectation
    We come across some web frameworks and technologies that we think will succeed, but they wither away as time passes by and don't succeed to the level we expected. Which web frameworks and or technologies did you come across that you thought would succeed but did not as per your expectations? For example, I thought that Opa Lang[0] and UrWeb[1] would succeed but did not, even though the ideas were sound. [0]... - Source: Hacker News / almost 3 years ago
