Agent Store is a hub where users can discover, test, and share autonomous agents and workflows. With Try Mode, users can interact with agents in a safe, sandboxed environment before installing them, exploring functionality and confirming performance without risk. The platform also supports public sharing, enabling creators to publish agents and workflows for the broader community. This promotes collaboration, learning, and adoption of tested, reliable workflows while giving developers visibility and feedback on their creations.

The Autonomous Browser in Numun.io (http://Numun.io) is a fully actionable AI agent embedded in a live browser session. Users interact through natural language, and the agent executes real tasks online, like navigating websites, filling forms, extracting data, and interacting with web applications—without manual coding or scripting. This is not just a “chatbot.” It’s a production-grade autonomous operator: the system interprets intent, plans multi-step workflows, and performs actions reliably in real time, bridging the gap between AI reasoning and web-based execution.

AI Builder + Agent Studio is a system for designing, testing, and deploying AI agents and autonomous workflows as structured, production-ready graphs, not fragile prompts. At the core is Agent Studio, where workflows are defined as explicit graphs made up of agents, tools, conditionals, loops, routers, and outputs. The AI Builder sits on top of this system and generates complete workflows automatically. Instead of writing code or wiring nodes manually, users describe the goal—and the AI Builder constructs a valid workflow graph. Every workflow can be tested using a test harness, ensuring agents execute correctly before deployment. This project demonstrates how AI agents can be treated like real software systems—versioned, validated, and orchestrated—instead of one-off prompt chains.

Cover image for 🚨 Your database query works…

🚨 Your database query works… but it’s taking 3 seconds? Before rewriting the whole backend, check your database indexes. One missing index can turn a fast query into a slow one as your data grows. Optimize the query before optimizing everything else. ⚡ Have you checked your database indexes recently? 👇

Cover image for 🚨 A bug that looks

🚨 A bug that looks like a frontend problem might actually be your backend. I once spent time checking UI code, only to find the real issue was an API returning the wrong data. When debugging, I always check the full data flow: Frontend → API → Backend → Database Debug the source, not just the symptom. 🔍 Have you ever found a backend bug while fixing a frontend issue?

Cover image for 🚨 The API is returning

🚨 The API is returning 200… but your data is wrong? This can be harder to debug than a clear error. When I troubleshoot backend issues, I check: 🔍 Database queries 🔍 API request/response data 🔍 Authentication state 🔍 Backend logs 🔍 Frontend data handling A successful API response doesn't always mean the application is working correctly. Sometimes, the real bug is hiding in the data flow. Have you ever spent hours debugging a problem that turned out to be one small line of code? 😅

Cover image for Your Supabase app is working…

Your Supabase app is working… but your database is still exposed? 🔐 One mistake I see developers make is setting up authentication and forgetting about Row Level Security (RLS). If you're using Supabase, don't just create your tables and move on. Make sure you: ✅ Enable RLS on your tables ✅ Create policies for who can read data ✅ Create policies for who can insert or update data ✅ Never expose sensitive service keys in the frontend ✅ Test your policies with different user accounts Authentication tells you who the user is. RLS helps control what they can access. Have you ever had an RLS policy block something that should have worked? 👇
