GStack is an open-source Claude Code workflow system created by Y Combinator CEO Garry Tan, designed to encode specialized AI roles for planning, code review, QA, and shipping. Built with Bun and Playwright, it uses route-aware QA and structured release workflows to connect code changes with actual application behavior. Enables developers to achieve 10,000+ lines of quality code per week.

Cursor Composer 2 is an advanced agentic coding model built into the Cursor IDE, released March 19, 2026. With a 200,000-token context window, it autonomously plans and executes complex, multi-file coding tasks across an entire codebase — handling file edits, terminal operations, and tool use at frontier-level performance. It is used by over 50,000 businesses including Stripe.

Kilo Code is an open-source AI coding agent for VS Code, JetBrains, and CLI that generates code from natural language, automates complex tasks, and runs terminal commands. It supports 500+ AI models at provider rates and features an Orchestrator mode that breaks complex tasks into coordinated subtasks across planner, coder, and reviewer agents. With 1.5M+ users and 25T+ tokens processed, it's the #1 coding agent on OpenRouter.

Ship reliable AI applications with confidence. Enterprise platform for building, testing, and deploying production-ready AI agents with monitoring and reliability features.

Gemma 4 is Google DeepMind's most capable open-source AI model family, released in April 2026 under the Apache 2.0 license. It features Dense and Mixture-of-Experts (MoE) architectures in four sizes (E2B, E4B, 26B, and 31B), purpose-built for advanced reasoning, coding, and agentic workflows. The E2B and E4B variants are specifically optimized for on-device inference on smartphones and edge hardware like Raspberry Pi, with deep collaboration from Qualcomm and MediaTek.

AI-powered long-term memory for your entire workstream. Automatically captures context from code, docs, and chats as you work, then surfaces relevant memories when you need them. Runs locally with on-device AI for privacy.
