AgentSwarms – free hands-on playground to learn agentic AI, no setup

In plain words

AgentSwarms is a free online playground for learning agentic AI without requiring any installation or configuration. It allows users to experiment with AI agent systems through a hands-on interface accessible directly in a web browser. The tool is designed for anyone interested in exploring how AI agents work and interact with each other, from beginners to those seeking practical experience with agentic AI concepts.

From the sources

AgentSwarms has officially made source code available for its powerful multi-agent engine. Originally known as the premier learning platform for agentic AI, AgentSwarms can now be deployed directly onto your own infrastructure as a unified Agentic AI and AI Powered Business Intelligence platform.

Hands-on playground for Agentic AI. Free: 8 tracks, 50+ lessons, 50+ runnable agents & swarms, 25 build-along labs — RAG, tools, guardrails, swarms.

50+ lessons paired with 50+ runnable agents and swarms: ReAct, Reflexion, Graph RAG, text-to-SQL. Open one in your browser, fork it, and break it. Start from a working multi-agent system, not a blank canvas. Each template ships wired agents, tools, memory, and a swarm you can run in one click — export in your choice of framework, modify and run in your choice of environment. An orchestrator routes work across specialist agents — intake, research, and synthesis — handing off context at each step until the task is done. Parallel agents pull signals, score sentiment, and a synthesis agent writes the final memo — the analyst workflow as a runnable swarm. A release pipeline of agents plans the…from agentswarms.fyi

  We build AI agents to find vulnerabilities in other AI agents. The playground started as an internal tool that we used to test our own offensive agent Nyx. But we realised that hacking an AI is about have as wide a distribution of attacks as possible, especially those which aren't in the distribution of the models. So we are launching playground as a platform to crowdsource agent jailbreaks. And although hacking AI is super fun and we are sure people will do it for free, we want to reward those who help us push forward the offensive frontier of AI. So we are committing $100K in prizes over…

  Agent ArenaJun 2026 · arena42.ai · ▲348

  Creator here. I built Agent Arena to answer a question that kept bugging me: when AI agents browse the web autonomously, how easily can they be manipulated by hidden instructions? How it works: 1. Send your AI agent to ref.jock.pl/modern-web (looks like a harmless web dev cheat sheet) 2. Ask it to summarize the page 3. Paste its response into the scorecard at wiz.jock.pl/experiments/agent-arena/ The page is loaded with 10 hidden prompt injection attacks -- HTML comments, white-on-white text, zero-width Unicode, data attributes, etc. Most agents fall for at least a few.…

  AgenticSeek – Self-hosted alternative to cloud-based AI tools2025 · github.com · ▲122

  I’ve spent the last two months building AgenticSeek, a privacy-focused alternative to cloud-based AI tools like ManusAI. It runs entirely on your machine—no API calls, no data leaks. Why AgenticSeek? Optimized for local LLMs (developed mostly on an RTX 3060 running deepseek r1 14b). Truly private: All components (TTS, STT, planner) run locally. More responsive than alternatives (we respond fast to issues + active Discord). Designed to be fun—think JARVIS-like voice control, multi-agent workflows, and a slick web UI. Current Features: Web browsing (research + form filling), code…

  Open-source playground to red-team AI agents with exploits publishedMar 2026 · github.com · ▲30

  We build runtime security for AI agents. The playground started as an internal tool that we used to test our own guardrails. But we kept finding the same types of vulnerabilities because we think about attacks a certain way. At some point you need people who don't think like you. So we open-sourced it. Each challenge is a live agent with real tools and a published system prompt. Whenever a challenge is over, the full winning conversation transcript and guardrail logs get documented publicly. Building the general-purpose agent itself was probably the most fun part. Getting it to reliably use…

  Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
