Products that do what We Built Mix, a Multimodal Agents SDK does

Mix is a multimodal agents SDK. It comes with a GUI playground for testing and debugging SDK workflows. • Built for multimodal workflows instead of code based workflows • The GUI playground is built from the typescript SDK • All project data is stored plain text and native media files - absolutely no lock-in. • The backend is an HTTP server, check out our python and typescript SDK's

    Why we built it: • Claude Code: great for coding, but no video/audio support, localhost only • OpenAI SDK: single-model, no native multimedia tools • Both: no integrated DevTools for debugging agent reasoning So, we built Mix as an alternative for multimodal applications. • Native video/audio/PDF analysis tools (via Gemini for vision, Claude for reasoning) • Multi-model routing instead of single-provider lock-in • One-command Supabase setup for cloud deployment (vs localhost-only) • HTTP architecture that enables visual DevTools alongside agent workflows • Go backend: 50-80%…

    Mix is an open-source, local agent for multimodal claude code. Claude code users will feel at home. - Uses ffmpeg and local apps like blender instead of clunky cloud based editors - All project data is stored plain text and native media files - absolutely no lock-in. - The backend is an HTTP server, meaning that the frontend is just one of possible clients. - - Our SDK with stdio interface (similar to claude code SDK) is launching soon.

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    Hey HN, In the months since we initially released Burr (https://news.ycombinator.com/item?id=39917364), we have been hard at work. We wanted to share some of the most exciting changes we’ve made to build Burr out as a full-stack development framework for AI agents. In case you don’t recall, Burr is an open-source python library that makes it easier to build and debug GenAI applications & agents by representing them as graphs of simple python objects/functions. Burr only abstracts away system-level concerns (state persistence, debugging, observability), and does not…

    The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.

    A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!

    I was building my personal agent, but I had to use Telegram, as it was the easiest platform to integrate. I wanted to build the harness and agent, not the infrastructure around these two, yet my UX was struggling. I stick to iMessage, and then I had to use another app to interact with my agent... So I spent a weekend on building a TypeScript SDK, that unifies how to interact with different iMessage providers (as there is no official way to use iMessage), so you can play around with them, without having to commit to one, nor with a need to rewrite half of the codebase to change the…

    Hi HN, AgentBox is an SDK for running coding agents (Claude Code, Codex, OpenCode) inside sandboxes (Docker, E2B, Modal, Daytona, Vercel). One API. Swap the agent or the sandbox and your code doesn't change. Think of it as what the AI SDK did for LLMs, but for agent + runtime. Most wrappers call agents in non interactive mode (claude --print, codex exec). AgentBox instead boots each agent's native server inside the sandbox (Codex app-server over JSON-RPC, OpenCode serve over HTTP/SSE, Claude Code's SDK WebSocket transport) and drives it from the host, behaving like an interactive…

    Claude Code's source map leaked last month. Instead of just reading it, I fed the entire source into Claude Code itself and asked it to extract the core agent loop logic. The result: open-agent-sdk — a drop-in replacement for claude-agent-sdk that's fully open source and doesn't spawn a CLI subprocess. Why this matters if you've built with claude-agent-sdk: claude-agent-sdk is just a thin wrapper around the Claude Code binary. It works, but it's a black box — when something breaks, you're stuck. Every query creates a new Claude Code process. That's fine on a laptop, not fine when you're…

    A few weeks ago, we started looking for a good framework to build agentic workflows within our Rails monolith at Chatwoot, but couldn't find anything that fit our needs. So, we decided to build our own. The SDK lets you create multiple AI agents that can interact with users, use tools, share context, and hand conversations off to each other. The SDK is provider-agnostic and designed to be thread-safe. Here's a link to our GitHub repository with the entire code, a quick-start guide, as well as an interactive example: https://github.com/chatwoot/ai-agents Fair warning: This…

    URL: http://mixcastr.com/ The end of the weekend is here, and my project (roughly 15 hours) is done. It's called Mixcastr, and it uses the Sound Cloud API to serve songs from their platform, based on user queries. So yeah, it's really just a glorified search interface - but I had fun making it. Hopefully next weekend I'll expand on its functionality/utility. Breakdown: Sinatra, Twitter Bootstrap, SoundCloud JavaScript SDK, and Heroku, Polymorphs, CloudMade

    Hi HF, I'm Terrell, and we built an open-source app that lets developers create their own Operator with a Next.js/React front-end and a flask back-end. The purpose is to simplify spinning up virtual desktops (Xfce, VNC) and automate desktop-based interactions using computer use models like OpenAI’s There are already various cool tools out there that allow you to build your own operator-like experience but they usually only automate web browser actions, or aren’t open sourced/cost a lot to get started. Spongecake allows you to automate desktop-based interactions, and is fully open…

    Link: https://docs.trysoma.ai/ For the past ~9 months I’ve been building Soma, an open-source AI agent & workflow runtime written in Rust, with a TypeScript SDK (Python coming soon). It’s not a framework; it’s meant to sit underneath whatever agent/tooling code you already write (Vercel AI SDK, LangChain, custom code, etc.). It provides features around your framework + a better DX for building agents. I’ve tried to take a Next.JS model: open-source, good DX, self-deployable. I originally set out to build a vertical back-office/operations product for SMEs. I needed a…
