This could be the next big thing! It is great how AI agent can now build AI agents

congrats on the launch guys!! looks super cool, awesome decision to open source!

Huge congrats to Alexander and the SmythOS team on the open source launch! 🚀

Opening up the core under MIT is a big step for the agentic web: this really lowers the barrier for anyone who wants to experiment or build with autonomous AI. I can already imagine teams using SmythOS to spin up personal research agents, automate internal workflows, or even power customer-facing bots that truly "act" on users' behalf. The browser automation + modular flows combo opens up a ton of possibilities, from automated QA to next-gen data pipelines, and even creative tools that connect across different services.

Really appreciate your focus on keeping things open and developer-friendly. And thanks for featuring Logto in your stack. Honored to be part of the journey! Can't wait to see what the community builds with SmythOS. Starred, joined, and cheering you on!

Thanks everyone for the energy. I’m excited to see how you take this and run.

P.S. We’re iterating and testing hard, so please share any pain points, big wins, or other feedback—it’s what keeps us pushing the limits. We’ve also got a lot of exciting updates in the pipeline, so stay tuned!

feels like if there were ever the right time to get into building software if one already hasnt, then now is the time and starting from somewhere like SmythOS open source seems amazing

We built SmythOS to take the friction out of building with LLMs and agents, whether you're prototyping a side project or deploying something production-grade.

Here's what it brings to the developer community:

🧠 Agent Architecture

• Create agents programmatically or via .smyth config files

• Define behavior, models, tools, and skills cleanly

• Chain logic using custom skills or call agents from agents

• Easy agent interactions ( .prompt() , .chat(), .mcp() )

🔐 Built-in Security Model

• Candidate-based ACL (Access Control Lists) from the ground up

• Scoped storage ensures data isolation between agents by default

• Easily enable data sharing via shared scopes (e.g., Scope.TEAM)

• Ready to integrate with third-party auth/account systems

💬 Prompting and Streaming made easy

• Send prompts and get complete response or and stream the responses

• Full event support (data, end, error, etc.)

• Attach files directly to prompts (like PDFs or images)

• Easy chat implementation with built-in persistence

📚 Vector Database Integration

• Built-in support for Pinecone, Milvus, RAMVec and more coming (swap with 1 line)

• One-liner PDF/DOCx/Text/MD... parsing and indexing

• Search with topK results and semantic embeddings

🗃️ Unified Swappable Storage Interface

• Local and S3-compatible storage out of the box

• Write, read, and delete files with simple APIs

• Scope isolation for data privacy (agent-specific or shared)

🧰 Fluent, Strongly-Typed SDK

• Introspectable methods with autocomplete

• Minimal boilerplate, maximum clarity

• Consistent patterns across features (e.g., .storage, .vectorDB, .prompt())

We designed it to be modular, extensible, and fun to use, so devs can spend time building cool things, not stitching together infrastructure.

💡 It's open source and ready for your experiments.

We’re excited to see what you build, whether it’s an AI-powered chatbot, assistant, RAG app, or something totally unexpected.

Big thanks to the SmythOS team — you've been grinding on this for a long time, and today’s a milestone.

To the developers, builders, and dreamers: this is for you. You can now build agents with true autonomy and control using our open-source stack — and easily deploy them anywhere.

The world is yours. Can’t wait to see what you build.

Tried SmythOS super clean experience. And just one thing: setting up MCP with browser agents was a bit tricky at first. A plug-and-play template would make onboarding even easier.

Looking forward to the visual builder any chance it’s coming sooner? 🙌

Orchestrate AI, or it may orchestrate you! Win the fight by using SmythOS.

SmythOS is the open-source backbone for building AI agents—no manual coding needed. Just describe your goal, and Agent Weaver builds it using top AI models and APIs!

Really excited to see SmythOS open to the community! I’ve been looking for something that makes building AI agents simple and fun—this looks like it’s exactly that. Time to start experimenting! 🔥🔥

This is what MANY developers have been waiting for🔥

And thanks to their patience, we have launched a solid platform that covers all the bases 💪

A HUGE thank you to all the SmythOS Engineers and Product Team, for working their butts off to make this a reality 🙏

I for one, am super excited at the ability to fast install, and get up and running in a heartbeat ❤️

LET'S GOOOOOOOOO 🚀

Open-source runtime and SDK? That's huge! Going to try the CLI, brb 😀

BTW, the PH launch trailer is 🔥😍 how did you make it?
