Products that do what I used Claude Mythos to build my startup in 1 day does

This sounds clickbait, but it’s true: I used Claude Mythos to build the full site in 1 day. Then Anthropic removed the model, so I had to go back to Opus.

    Hey HN. I built this because my Anthropic API bills were getting out of hand (spoiler: they remain high even with this, batch is not a magic bullet). I use Claude Code daily for software design and infra work (terraform, code reviews, docs). Many Terminal tabs, many questions. I realised some questions are ok to wait on and with that comes some cost savings. So here is a small MCP that lets you send work directly to Anthropic's Batch API from inside Claude Code, for the same quality responses just 50% cheaper, results come back in ~30min-1hr. How it works: you type /batch review this…

    Boris Cherny (Claude Code creator) recently dropped a threads on how his team at Anthropic uses Claude Code. The key insight: they don't treat it as a static config. After every correction, they tell Claude "Update your CLAUDE.md so you don't make that mistake again." Claude writes a rule for itself. They review it, commit it to git. The mistake never happens again. I cross-referenced his tweets with Anthropic's official docs and other best practices for CLAUDE.md and then packaged it into a starter kit: - Fill-in-the-blank templates for Next.js/TypeScript, Python/FastAPI, and a…

    I got frustrated with Claude's official platform limitations - conversations disappearing, no customization options, and clunky file handling. So I built my own interface over a weekend! GitHub: https://github.com/chihebnabil/claude-ui What it does: - Saves all conversations locally (SQLite + Drizzle ORM) - Lets you customize Claude's personality per chat - Handles file attachments properly + caching input tokens - Dark/light mode - No conversation limits - Markdown & code syntax highlighting Tech stack is pretty simple: - Nuxt 3 for the frontend - Anthropic's SDK…

    Hey HN. I built an AI agent harness over the past few months and I'm open sourcing it today. Some context on why. I've been building with Claude Code daily using this harness. It orchestrates multiple AI agents as a team, with a dashboard, chat, kanban board, the works. I used it to build a full SaaS product (MyUpMonitor, https://myupmonitor.com) in about 24 hours of focused coding. Then yesterday Anthropic announced Mythos and decided to keep it behind closed doors. Meanwhile I'm paying for Claude and I can't access their best model. I don't think that is nice at all... So I'm…

    Hey everyone, I’m the maintainer of the popular screenshot-to-code repo on Github (46k+ stars). When Claude Opus was released, I thought to myself what if you could send in a video of yourself using a website or app, would the LLM be able to build it as a functional prototype? To my surprise, it worked quite well. Here are two examples: * In this video, you can see the AI replicating Google with auto-complete suggestions and a search results page (failed at putting the results on a separate page). https://streamable.com/s24pq6 * Here, we show it a multi-step form…

    I built an artificial life simulator that fits in one HTML file (~1400 lines ~50KB) with Claude Opus 4.6, interestingly, I didn't even ask it to build the game itself, I've requested to create the software that didn't exist before and not use any dependencies, third-party libraries or ask questions. Firstly Opus 4.6 made photoshop clone that barely worked, but had nice and neat UI with all common features for the image editor, then I've called that crap and asked to really build someting that wasn't there, it made Emergent there. Please check it out and tell what you think, of course it's a…

    I built a collection of professional slash commands for Anthropic's Claude Code that provide structured workflows for common software development tasks. These commands are directly inspired by and adapted from Anthropic's own claude-code-best-practices (https://www.anthropic.com/engineering/claude-code-best-practices) documentation, translating their recommendations into executable workflows. The suite includes commands for: • Comprehensive code reviews with security and performance analysis • End-to-end feature development with planning, implementation, and testing •…

    Anthropic recently released a new model called Claude. As I was unable to access this model, I noticed a lot of discussions on Twitter regarding comparisons and use cases of Claude and ChatGPT. To keep track of these conversations, I created a repository that compiles information on the following topics: * Comparisons between Claude and ChatGPT * Use cases * Limitations of Claude Check it out and please create a bug/PR if more threads can be added: https://github.com/taranjeet/awesome-claude

    Anthropic's usage analytics dashboard is only available to Team and Enterprise org admins. On a Pro or Max plan all you get is /usage and the claude.ai usage page, which show where you stand right now but not where you're heading. I looked at various open-source projects but none quite matched what I had in mind: an all-round control panel for Claude Code that's also a single binary, with no dependencies and no install steps. The other thing I cared about was forecasting the usage limits. Existing tools do burn-rate projections (ccusage) or percentile heuristics…

    Hey guys, I built this platform out to allow users to passively earn crypto for non-intrusive highly targetted ads. One of the things that's awesome is that there's an option to receive payouts in Anthropic's pre-IPO stock (via PreStocks on Solana). So you can use Claude Code and receive Anthropic stock . Let me know what you guys think. Feedback is welcome and please give it a try to install.
