01
Codex is an advanced AI coding agent designed to help developers build, refactor, and ship software with increased efficiency. Acting as a command center for agentic workflows, it handles end to end tasks ranging from complex migrations and feature building to automated code reviews and issue triage. By integrating seamlessly into your development process, Codex allows teams to automate routine engineering work and focus on high impact system design. Whether you are working on a small prototype or a large scale codebase, Codex adapts to your team standards to raise code quality and accelerate delivery.
02
Feyn Labs helps you build and deploy specialized AI models tailored to your specific data and workflows. Instead of relying on borrowed models that do not learn from your unique expertise, Feyn allows you to own your weights and create systems that grow sharper over time. Their process focuses on discovering quality metrics, refining your stack, specializing models for your product, and creating feedback loops for continuous improvement in production.
03
Bishakh Ghosh is a researcher and engineer with a PhD from IIT Kharagpur, focusing on blockchain interoperability, distributed systems, and cloud computing. His work spans academic research, software development, and technical leadership, including numerous publications in prestigious computer science conferences. Beyond research, he has hands-on experience in web application development, open-source contributions, and teaching, making him a versatile expert in modern computing architectures.
04
Annotate-8 is a tool that lets you record your screen while drawing and talking to explain exactly what you need. Once you are done, it sends that recording to an AI agent to handle the task. It works perfectly with coding assistants like Claude or Cursor, and because it runs locally, your data stays private and free to use.
05
Laserbrain is a smart recursion harness designed to keep autonomous AI agents on track. By providing a fixed, outside reference point, it detects when agents begin to loop, over-deliberate, or drift from their original goal. It works by monitoring state changes and progress, allowing agents to self-correct or escalate to human intervention when they lose their way. Perfect for developers building complex AI workflows, Laserbrain helps ensure agents stay focused on their objectives rather than spiraling in unproductive cycles.
06
Claude Overlay is a frameless, always-on-top chat window for Claude Code that stays visible over your workspace. You can summon it with a simple hotkey to ask questions about whatever you are working on, and it will capture and read your monitors to provide context-aware answers. It runs the full Claude Code agent on your personal subscription without needing an API key, allowing it to actively edit files and run terminal commands. This tool is open source, licensed under MIT, and currently available for Windows users.
07
TrustedRouter gives you a single OpenAI-compatible API to access hundreds of AI models, all running on attested infrastructure with end-to-end encryption. You get Confidential routes for sensitive workloads, ZDR (Zero Data Retention) routes, automatic provider failover, and the ability to bring your own keys (BYOK). Best of all, we don't log any prompts or outputs, so your data stays private.
08
LeetCode is the leading platform for developers to sharpen their programming skills and prepare for technical interviews. With a massive library of over 4,000 practice problems and a thriving community, it provides the tools you need to succeed in your career. From interactive coding playgrounds to company-specific interview resources, LeetCode helps you build confidence and proficiency in 14 popular languages.
09
Shepherd is a terminal built for running coding agents across multiple tabs, panes, and even remote machines. It keeps your terminal sessions alive even if you close the app, so you never lose progress. You can see exactly which agents are working and which are waiting, and you can jump back into their files and changes without missing a beat. Agents are aware of the current Shepherd context, can control tabs and panes, and gather feedback through browser reviews. Meanwhile, you get a real-time view of every agent's status.

Manta AI acts as an autonomous testing agent for your web applications. Just provide a URL and the agent explores your site like a real user, mapping out flows and finding bugs. You can describe testing scenarios in plain English without writing any scripts, and the system automatically updates its tests when your UI changes. It runs locally or on your own servers to test private networks and behind the firewall applications.
