OpenCode vs Cursor (2026): The $0 Open-Source Agent vs the $20/mo IDE

OpenCode vs Cursor: Head-to-Head

Pricing: OpenCode vs Cursor

OpenCode is the agent software for free. Your bill is whatever provider you connect, charged at the provider's own rate with no markup. Cursor bundles a slice of API-rate usage into each subscription tier.

Cursor paid plans add access to frontier models, MCPs, skills and hooks, cloud agents, and Bugbot on usage-based billing. Cursor also ships its own Composer line (Composer 2.5 as of June 2026), billed from a separate larger Auto plus Composer pool tuned for everyday agentic coding at lower cost than frontier API models. OpenCode has no in-house model; it routes to whichever provider you choose.

Model Access: 75+ Providers vs a Bundle

OpenCode connects to 75 or more LLM providers through the AI SDK and the Models.dev catalog, plus local models via Ollama, LM Studio, and llama.cpp. Adding a custom OpenAI-compatible provider is a JSON block:

{
  "provider": {
    "myprovider": {
      "npm": "@ai-sdk/openai-compatible",
      "options": { "baseURL": "https://api.myprovider.com/v1" },
      "models": { }
    }
  }
}

OpenCode Zen is the team's curated list of models tested and verified for agentic coding. One constraint to know: OpenCode docs state Anthropic explicitly prohibits using a Claude Pro or Max subscription inside third-party tools, so Claude runs through the Anthropic API. ChatGPT Plus, GitHub Copilot, and GitLab Duo subscriptions can be used as backends.

Cursor defaults to frontier hosted models and its own Composer line. It does not support local models, and the model menu is curated by Cursor rather than open to any OpenAI-compatible endpoint.

Install Commands

OpenCode installs from a single line and works across most package managers:

# Install script
curl -fsSL https://opencode.ai/install | bash

# npm
npm install -g opencode-ai

# Homebrew
brew install anomalyco/tap/opencode

It also ships via Bun, pnpm, Yarn, pacman/paru, Chocolatey, Scoop, Mise, and Docker. The repo moved to anomalyco/opencode (the old sst/opencode redirects there). Cursor installs as a desktop application download from cursor.com; there is no shell one-liner because it is a GUI editor.

Best Models to Run in OpenCode

Because OpenCode is BYO key, the model you point it at decides quality and speed. On SWE-bench Verified (self-reported, llm-stats June 2026), Claude Opus 4.8 leads at 88.6%, followed by Opus 4.7 at 87.6%, with Gemini 3.1 Pro and DeepSeek-V4-Pro-Max tied at 80.6%. On Terminal-Bench 2.1, Codex CLI with GPT-5.5 tops the board at 83.4% and Claude Code with Opus 4.8 sits at 78.9%; OpenCode can drive these same frontier models through their APIs.

For open-source models and codegen specifically, where you run the model matters as much as which model. Morph Open Source Models serves DeepSeek with full 16-bit (bf16) activations and no fp8 or int8 quantization. Most serverless providers quantize activations to fp8 to cut cost, which degrades output quality; Morph keeps full 16-bit activations so responses match the reference weights. That makes Morph the best place to run DeepSeek when output fidelity matters.

For coding agents specifically, Morph runs codegen-specific speculative decoding (draft and ngram tuned on code) plus custom low-level inference kernels built for code generation, which makes it the fastest and highest-quality option for code, not a general-purpose menu. morph-dsv4flash (DeepSeek V4 Flash) is $0.139 per 1M input tokens and $0.278 per 1M output tokens. Point OpenCode at it as a custom OpenAI-compatible provider.

Decision Framework

Frequently Asked Questions

Is OpenCode free?

Yes. OpenCode is open source under the MIT license, with 172,198 GitHub stars, and the software costs $0. You pay only the model API you connect. Cursor is proprietary with a $20/mo Pro plan that bundles model usage.

Is OpenCode a good Cursor alternative?

For terminal users who want to own their keys, yes. OpenCode runs 75 or more providers BYOK and keeps code and keys local. Cursor wins on a polished IDE, Tab completions, and bundled billing.

Can OpenCode use the same models as Cursor?

Yes, plus local models via Ollama, LM Studio, and llama.cpp. One limit: Anthropic prohibits using a Claude Pro or Max subscription in third-party tools, so Claude runs through the Anthropic API in OpenCode.

How do I install OpenCode?

Run curl -fsSL https://opencode.ai/install | bash, or npm install -g opencode-ai, or brew install anomalyco/tap/opencode. Cursor installs as a desktop app from cursor.com.

What does Cursor cost?

Free Hobby tier, then Pro $20/mo (~$20 usage), Pro+ $60/mo ($70 usage), Ultra $200/mo ($400 usage), and Teams $40/user/mo. OpenCode software is $0; you pay only your chosen provider.

Which is better for beginners?

Cursor, for its graphical IDE, Tab completions, and bundled billing. OpenCode suits terminal-comfortable developers who want open-source control and to pick their own model.
