Title: Hi folks! I’m Eric Rowell, and I’m really excited to share what our startup has been working on: <a href="https:&#x2F;&#x2F;www.second.dev">https:&#x2F;&#x2F;www.second.dev</a>.  Second automates codebase migrations and upgrades for developers using AI agents and static analysis.  You log in, connect Second to your GitHub repo, run a module, and get a pull request.<p>Here’s a demo video: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=d5IldYeCPBY">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=d5IldYeCPBY</a>.<p>We believe that most developers want to spend their time innovating and creating new software. A lot of time at large companies is spent on basic codebase maintenance instead. Not all of this is automatable, but some is! And the technology to support it is developing rapidly.<p>Unlike generic AI agents, our AI agents specialize in codebase migrations and upgrades.  The agents run modules which include a procedural plan of attack, and execute prompts using RAG (Retrieval-Augmented Generation) to utilize the most up-to-date context to do the job, including documentation and code examples, crawled with LangChain and stored in vector DBs.  Our agents also reshape directory structures, resolve dependencies, and update build systems.  The agents can run in our Second Cloud, in your own AWS or Azure VPC, or they can run fully on-premise with open source LLMs.<p>Today, we specialize in Angular → React, CRA → Next, JS → TS, and Upgrade Next.  We’re building new modules every week, and we plan to open up an SDK to enable the Second community to build their own modules too.<p>You can try Second for free on codebases up to 2MB.  For larger codebases, we charge $10&#x2F;MB for the first module run, and then after that you can run it as many times as you like for free.<p>Please try it out and let us know what you think.  We are obsessed with codebase migrations and upgrades, so please let us know how we can help!
