Cursor Composer 2

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.

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.

Warp is an AI-native agentic development environment built from the ground up for developers. It features natural-language command generation, multi-agent orchestration via Oz (launched February 2026), and IDE-style terminal editing — letting developers describe tasks in plain English and have AI agents build, debug, and ship code autonomously. Over 700K developers use Warp with Pair and Dispatch agent modes for local and cloud-based agentic workflows.

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

Qwen 3 Coder is Alibaba's open-source AI coding model optimized for agentic software engineering. It supports a native 256K token context window (extendable to 1M tokens), enabling it to process vast codebases in a single session. Qwen 3 Coder scored 44.3% on SWE-Bench Pro and powers the Qwen Code CLI agent for terminal-based development.

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.
