Compare AI Tools

Cursor is a fork of VS Code rebuilt around AI-first workflows, with planning, debugging, and code review baked into the editor itself. VS Code is the open base that Cursor builds on, and it reaches similar AI capabilities through extensions like GitHub Copilot, but those capabilities are layered on rather than native.

OpenCode ships with 75+ LLM providers and a ready-to-run interface across terminal, desktop, and IDE. Pi Coding Agent starts minimal and grows through TypeScript skills, prompt templates, and themes you write yourself. The choice is between starting with everything and trimming, versus starting with nothing and building exactly what you need.

OmniRoute and Sub2API both put many LLM providers behind a single endpoint, but they solve different problems. OmniRoute focuses on request-level efficiency through prompt compression and auto-fallback across 160+ providers, while Sub2API focuses on account-level management by pooling existing Claude, OpenAI, and Gemini subscriptions with quota distribution and billing controls.

Both tools bring an agentic coding assistant to your terminal, but Claude Code locks you into Anthropic's models while OpenCode lets you route requests through any of 75+ LLM providers. The real choice is between a tightly integrated single-vendor experience and a provider-agnostic setup you can tune to your own cost and model preferences.
