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.

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.

z.AI's flagship open-weight model released February 2026 with 744B total parameters (40B active). Designed for complex systems engineering and long-horizon agentic tasks. Integrates DeepSeek Sparse Attention for efficient long-context workloads. Strong in reasoning and code generation.

Low-code AI builder for agentic and RAG applications. Build and deploy AI agents and MCP servers with a visual drag-and-drop interface, supporting all major LLMs, vector databases and a growing library of AI tools.

Cursor Automations is the latest AI coding agent feature from Cursor, launched in March 2026, that enables always-on background agents triggered by code changes, Slack messages, or timers. Built on Cursor's AI-powered VS Code fork, it lets developers delegate entire implementation tasks to autonomous agents while focusing on higher-level direction. Supports multi-step agentic workflows, MCP apps, and cloud-based agent management.

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.
