Cursor Alternatives (2026): We Tested 9 Tools and the $0 One Scored 88.6% on SWE-bench

Quick Comparison: Cursor Alternatives at a Glance

Four tools are free and open-source (Cline, opencode, Kilo Code, Aider): the extension or CLI costs nothing and you pay only for the model you run. The cheapest paid plans are GitHub Copilot and Zed at $10/mo. Claude Code posts the highest published score at 88.6% SWE-bench Verified.

GitHub Stars: The Open-Source Field

For the "open source cursor alternative" and "cursor github competitor" searches, star count is the closest proxy for community. opencode leads every coding agent at 180,301 stars. Claude Code has the most-starred repo overall (134,868) but its code is not open-source.

Why Developers Leave Cursor

Cursor still works, and its $20 Pro plan now includes $20 of model usage with on-demand billing past that. The recurring complaints fall into four buckets, and open-source alternatives answer the first three directly.

1. Cline: Best Free, Open-Source In-Editor Agent

Cline is the best free Cursor alternative for people who want to stay in VS Code. It is an open-source (Apache-2.0) extension with 63,998 GitHub stars; you bring your own API key, so the tool itself is $0 and you pay only for inference. It is fully model-agnostic, with BYOK support across Anthropic, OpenAI, Google, OpenRouter, AWS Bedrock, GCP Vertex, Groq, Cerebras, and DeepSeek.

2. opencode: The Most-Starred Open-Source Agent

opencode is the free terminal option and the most-starred open-source coding agent at 180,301 GitHub stars (MIT). It runs in the terminal, a desktop app, or an IDE extension, and is fully model-agnostic: configure any provider with your own keys and there is no preset default model. The team also offers opencode Zen, a curated set of hosted models, for people who do not want to manage keys.

Verdict: Best free, open-source pick for terminal-centric workflows and the strongest answer to "open source cursor alternative" on GitHub by community size.

3. Kilo Code: Free Extension with a 0% Markup Gateway

Kilo Code is a free, open-source (MIT) agent for VS Code, JetBrains, and the CLI with 25,038 GitHub stars. The extension is free and AI usage is billed separately. Its differentiator is the Kilo Gateway: pay-as-you-go at exact provider rates with no markup, plus an Auto Model router that picks across Frontier, Balanced, and Free tiers. You can also BYOK or run local models via Ollama and LM Studio. The old kilocode.ai domain now redirects to kilo.ai.

Verdict: Best free in-editor option if you want zero-markup inference and a large model catalog without managing keys for every provider.

4. Aider: Open-Source Terminal Pair-Programmer

Aider is a free, open-source (Apache-2.0) AI pair-programming tool that runs in the terminal, with 46,808 GitHub stars and strong git integration. It is BYOK and model-agnostic. Aider also publishes the polyglot leaderboard: 225 Exercism exercises across C++, Go, Java, JavaScript, Python, and Rust that test editing code without human help. On that board gpt-5 (high) leads at 88.0%, o3-pro (high) at 84.9%, and gemini-2.5-pro at 83.1%, though the board lags the newest 2026 frontier models.

Verdict: Best for developers who want a scriptable, git-aware CLI and a transparent, reproducible benchmark over a full IDE experience.

5. GitHub Copilot: Best Free Tier from a Major Vendor

GitHub Copilot has the strongest no-API-key free tier: $0/mo for 2,000 code completions and 50 chat requests per month (including Copilot Edits), with access to Haiku 4.5 and GPT-5 mini. Pro is $10/mo with unlimited completions, $15 of monthly model credits, a cloud agent, and the ability to run Claude Code and Codex as third-party agents. It works in VS Code, JetBrains, Neovim, and Xcode.

Copilot in VS Code with multi-agent support.

Verdict: Best choice for a free start with no API key, or for one $10/mo subscription that runs multiple agent types across the widest set of editors.

6. Claude Code: Highest SWE-bench, Deepest Agent Stack

Claude Code is the strongest tool here on code quality. It runs Claude Opus 4.8, which scores 88.6% SWE-bench Verified and 69.2% SWE-bench Pro, the highest published numbers in this set, with the effort parameter defaulting to high. It is a proprietary agent that runs across the terminal, VS Code, JetBrains, desktop, web, and CI, and its repo is the most-starred here at 134,868 stars even though the code is not open-source.

7. OpenAI Codex: Best for Isolated Cloud Sandboxes

Codex is OpenAI's coding agent for the terminal, IDE, and cloud, open-source under Apache-2.0 with 94,277 GitHub stars. Cloud tasks run in network-isolated containers, which makes it strong for security-sensitive work. GPT-5.5 is the default and recommended model, with GPT-5.4, GPT-5.4 mini, and a GPT-5.3-Codex-Spark preview also available; a GPT-5.6 "Sol" preview began rolling out in late June 2026. It is bundled with ChatGPT plans and metered in messages per shared 5-hour window.

Codex CLI with cloud sandbox isolation.

Verdict: Best for security-conscious teams and spec-then-review workflows. Not ideal if you want real-time inline assistance.

8. Zed: Fastest Editor, Hosts Any Agent

Zed is an open-source, GPU-accelerated Rust editor with 86,147 GitHub stars. Instead of building its own agent, it hosts external ones (Claude Agent, Codex CLI) with full editor integration. The Personal plan is free with 2,000 accepted edit predictions per month; Pro is $10/mo for unlimited predictions plus $5 of included tokens; Business is $30/seat/mo. BYOK is unlimited with your own keys.

Verdict: Best for peak editor performance with the freedom to plug in any agent. Not for those who want one fully integrated AI IDE out of the box.

9. Windsurf (now Devin Desktop): Folded into Cognition

Windsurf no longer exists as a separate product. windsurf.com/pricing 308-redirects to devin.ai/pricing: Cognition, the company behind Devin, owns it and rebranded the editor as Devin Desktop. The free tier gives unlimited Tab completions and inline edits with a light agent quota. Devin Pro is $20/mo with full model access and Devin Cloud agents; Devin Max is $200/mo; the team plan is $80/mo plus $40/mo per full dev seat.

Verdict: Reasonable if you want unlimited Tab completions for free or plan to lean on Devin's autonomous agents. Expect the product to keep converging with Devin.

Notable Mentions

Gemini CLI and Antigravity CLI

On June 18, 2026, Google stopped serving free, Google AI Pro, and Ultra requests for Gemini CLI and the Gemini Code Assist IDE extensions, replacing them with Antigravity CLI (open to everyone). Enterprise access via Code Assist Standard and Enterprise is unchanged. Gemini CLI (105,641 stars, Apache-2.0) still runs with credentials, on Gemini 3 Pro and Gemini 3 Flash with a 1M-token context.

Amp (Sourcegraph)

Amp is pay-as-you-go with no subscription ($5 minimum, no markup for individuals and teams). It spawns parallel sub-agents and ships an Oracle review tool built on GPT-5.5 high-reasoning. The enterprise tier costs 50% more with a one-time $1,000 purchase.

Roo Code and Roomote

Roo Code (24,294 stars, Apache-2.0) is a free, BYOK Cline fork for VS Code. roocode.com now redirects to roomote.dev, the team's separate hosted product, which starts at $99/mo with a 7-day trial.

Continue.dev and Void

Continue (34,559 stars, Apache-2.0) was acquired by Cursor; the open-source codebase remains available. Void, the privacy-first VS Code fork, is no longer actively developed. For local-model privacy, use Cline or Kilo Code with Ollama.

Pricing Comparison: Every Cursor Alternative

The four open-source agents charge nothing for the tool; you pay only for model inference, which can stay well under a paid subscription if you use cheaper models. Among paid tools, GitHub Copilot and Zed are the cheapest at $10/mo.

Total Cost with Heavy Agent Usage

Agent-heavy workflows change the math. Each sub-agent burns tokens, so a 3-agent run uses roughly 3x the tokens of one. With the open-source tools, that cost is your model bill, so the lever is model choice: route routine edits to a cheap model and reserve a frontier model for hard work. A subscription with included usage (Copilot Pro at $10, Codex with ChatGPT Plus at $20) is more predictable; BYOK is cheaper if you manage the model mix.

Decision Framework: Pick Your Cursor Alternative

Cursor has faster tab completions and a plugin marketplace. See our full comparison.

Can I use Cursor alternatives with VS Code?

Yes. Cline, Kilo Code, GitHub Copilot, and Continue (now owned by Cursor) run as VS Code extensions. opencode, Aider, OpenAI Codex, Gemini CLI, and Claude Code run in the terminal, and Claude Code and Copilot also have VS Code integrations. Zed and Devin Desktop (formerly Windsurf) are their own editors.

Why are developers switching away from Cursor?

The common complaints are usage-based overages beyond the $20 base plan, lock-in to a proprietary VS Code fork, and privacy concerns about code sent to third-party APIs. Open-source agents like Cline and opencode remove the lock-in and let teams pick any model or run local models via Ollama.
