Claude Code vs Cursor vs OpenCode: What They Do (and What They Don't)
By Mitch Hazelhurst ·
If you write code in 2026, you've probably used at least one AI coding tool. Claude Code, Cursor, and OpenCode are three of the most popular. Each takes a different approach, but they share the same goal: help you write code faster.
This post is a fair comparison of what each tool does well, where it falls short, and what none of them do at all.
Claude Code
Claude Code is Anthropic's terminal-based agentic coding tool. You give it a task in natural language, and it autonomously reads your project, writes code, runs commands, and iterates until the task is done.
Strengths: Deep project context awareness. Can work across multiple files autonomously. Excellent at refactoring, debugging, and implementing features from high-level descriptions. Lives in the terminal, so it fits cleanly into existing workflows.
Limitations: Requires an Anthropic API key. The agentic loop can be slow for small tasks where a quick autocomplete would suffice. And like all code generators, it optimises for output, not for your understanding of that output.
Cursor
Cursor is an AI-first code editor forked from VS Code. It offers inline completions, a chat sidebar, and multi-file editing capabilities, all tightly integrated into the editing experience.
Strengths: Fast, polished UX. Inline completions feel natural. The tab-to-accept flow is the fastest way to generate code in context. Composer mode handles multi-file changes. Large community and active development.
Limitations: Proprietary and subscription-based. The editor-first approach means you're locked into their environment. And the speed of generation can encourage accepting code without reviewing it carefully.
OpenCode
OpenCode is an open-source terminal AI assistant similar in concept to Claude Code. It supports multiple LLM providers, runs in your terminal, and can read and modify your project files.
Strengths: Open source and provider-agnostic. No vendor lock-in. Community-driven development. Terminal native. BYOK model means you control costs.
Limitations: Smaller community than Cursor or Claude Code. Feature set is still maturing. Like the others, it focuses entirely on code generation and modification.
What none of them do
All three tools are excellent at generating code. None of them help you understand it.
They don't track what concepts you've encountered. They don't adapt their explanations based on what you already know. They don't remember that you struggled with async patterns last week. They don't show you how your understanding has grown over time.
This isn't a criticism. It's not what they're designed for. Code generation and code understanding are different problems. These tools solve the first one. The second one is unsolved.
Where pear fits
Pear doesn't compete with Claude Code, Cursor, or OpenCode. It complements them. Pear is a CLI learning tool that watches the code your AI tools generate and teaches you what it means.
It auto-reviews changes and explains concepts in context. It tags patterns, tracks your knowledge gaps, and adapts its teaching to your level. Pro users get a persistent learning state that follows them across sessions and projects.
The best workflow in 2026 isn't choosing between these tools. It's using a code generator and a learning layer together. Ship fast. Understand what you shipped.
