Best GitHub Copilot Alternatives in 2025 (Free and Paid)

Top GitHub Copilot alternatives — Codeium, Cline, Cursor, Windsurf, Continue.dev, Tabnine — compared on price, model quality, VS Code support, and privacy. Free options highlighted.

GitHub Copilot ($10/mo or free for students) is the most widely-used AI coding tool, but it has real limits: managed GPT-4o only with no local LLM option, no model flexibility, and pricing that adds up for larger teams. The agent mode lags behind Cursor and Cline for multi-file tasks. And if you want privacy — code that never leaves your machine — Copilot has no path for that.

The six alternatives below cover every scenario: free unlimited autocomplete, full AI agents in VS Code, local/offline operation, and privacy-first enterprise setups. Each has a meaningfully different trade-off.

The 6 best GitHub Copilot alternatives

1. Codeium by Windsurf team

Extension Free (unlimited)

Best for: Drop-in GitHub Copilot replacement with no usage limits and no credit card required.

Codeium is the closest direct Copilot replacement. It installs as a VS Code extension (also supports JetBrains, Neovim, and 40+ other editors) and provides unlimited inline autocomplete for free — no account tier, no 2,000-completion cap. It uses Codeium's own models rather than GPT-4o, but the autocomplete quality is comparable to Copilot's standard suggestions. If your main use case is autocomplete, Codeium is the obvious first stop before paying for anything.

Pros
  • Unlimited completions on free tier
  • 40+ editor integrations
  • No API key or credit card needed
  • Comparable autocomplete quality to Copilot
Cons
  • No local LLM option — cloud only
  • No GitHub PR/issue integration
  • Agent/chat features limited vs Copilot Pro

2. Cline

VS Code Extension Free + API costs

Best for: Developers who want full AI agent capabilities — multi-file edits, terminal commands, MCP tools — beyond what autocomplete can do.

Cline is a VS Code extension that gives you a powerful AI coding agent without any subscription. You bring your own API key (Anthropic, OpenAI, or any OpenAI-compatible endpoint including Ollama for local LLMs). Note: Cline has no inline autocomplete — it's an agent tool, not a completion tool. If you want Copilot-style tab completions, pair Cline with Codeium. If you want to replace Copilot with something more capable for complex tasks, Cline is a strong choice.

Pros
  • Stays in VS Code — no IDE switch
  • Supports any model via API key
  • MCP tool support for extended capabilities
  • Full local LLM support via Ollama
Cons
  • No inline autocomplete built-in
  • API costs add up with heavy use
  • Requires managing your own API keys

3. Cursor

IDE (VS Code fork) Free / $20 Pro

Best for: Developers who want the best all-in-one experience — Tab autocomplete, AI chat, and agentic multi-file edits in a single IDE.

Cursor is a VS Code fork with deep AI integration throughout the editor. Its Tab autocomplete is widely considered the best in the market — it predicts larger multi-line edits rather than just the next token. Composer mode handles complex multi-file refactors. The trade-off versus Copilot: it's $10/mo more expensive ($20 vs $10 Pro), you have to switch IDEs entirely, and the free tier caps at 2,000 completions per month.

Pros
  • Best-in-class Tab autocomplete
  • Strong Composer agent for multi-file edits
  • Familiar VS Code layout and extensions
  • Managed models — no API key setup
Cons
  • $20/mo Pro — double the price of Copilot
  • Free tier limited to 2,000 completions/mo
  • Requires switching from VS Code

4. Windsurf by Codeium

IDE (VS Code fork) Free / $15 Pro

Best for: Teams migrating from Copilot who want an IDE upgrade with a generous free tier and unlimited completions.

Windsurf is Codeium's VS Code fork and a strong alternative when you want more than Copilot's extension but don't want Cursor's price. The free tier gives unlimited completions (vs Copilot's paid model and Cursor's 2k cap). Cascade, Windsurf's agentic mode, is particularly good at large-codebase context and multi-file tasks. Pro is $15/mo, which undercuts Cursor by $5 and matches Copilot Enterprise pricing.

Pros
  • Unlimited completions on free tier
  • Cascade agent strong on large codebases
  • $15 Pro — cheaper than Cursor
  • Familiar VS Code layout and extensions
Cons
  • Free tier caps fast AI chat at 5/day
  • Requires switching from VS Code
  • Smaller community than Cursor

5. Continue.dev

VS Code / JetBrains Extension Free + model costs

Best for: Teams needing local LLMs for privacy, or custom model setups. The open-source default for self-hosted AI coding.

Continue.dev is fully open-source (MIT) and works in both VS Code and JetBrains. It provides tab autocomplete and AI chat in one extension, and supports Ollama, any OpenAI-compatible API, and all major cloud providers. Paired with a local Ollama model, it runs entirely offline with no data leaving your machine — making it the go-to choice for regulated environments or air-gapped development.

Pros
  • Fully open-source (MIT license)
  • Tab autocomplete + chat in one extension
  • JetBrains support
  • Full offline operation with Ollama
Cons
  • More setup required than managed tools
  • Autocomplete quality depends on model chosen
  • Less agentic than Cursor or Cline

6. Tabnine

Extension Free / $9 Pro / $15 Enterprise

Best for: Privacy-focused enterprise teams that need self-hosted AI autocomplete or air-gapped deployment.

Tabnine is the oldest AI autocomplete tool — it predates the ChatGPT era and has been training models on code since 2018. The Enterprise tier supports fully self-hosted, on-premises deployment, making it the strongest Copilot alternative for organizations with strict data governance requirements. Pro at $9/mo undercuts Copilot's $10. The free tier is limited but still useful for basic completions.

Pros
  • Self-hosted Enterprise option (air-gapped)
  • Longest track record in AI autocomplete
  • $9 Pro — cheaper than Copilot
  • VS Code, JetBrains, Neovim support
Cons
  • Free tier is more limited than Codeium
  • Autocomplete-only — no agent mode
  • Enterprise self-host requires infrastructure

FAQ

What is the best free GitHub Copilot alternative?

Codeium (Windsurf's free autocomplete product) offers unlimited free completions in VS Code — no usage cap, no credit card required. Continue.dev with local Ollama is also free with no usage limits, though it requires running a local model server. Start with Codeium: it's zero-friction to install and offers comparable autocomplete quality to Copilot.

Is Codeium better than GitHub Copilot?

For autocomplete quality alone, they're comparable — and Codeium is free. GitHub Copilot has better enterprise features (pull request reviews, security scanning, native GitHub integration) that Codeium doesn't offer. If you work heavily in GitHub and need PR-level AI assistance, Copilot's $10/mo is justified. If you just want fast inline autocomplete, Codeium wins on price.

Do Copilot alternatives work in VS Code?

Yes. Codeium, Cline, Continue.dev, and Tabnine all have VS Code extensions that install directly into your existing editor. Cursor and Windsurf are full VS Code forks — you switch to them entirely but they support the same extensions and keyboard shortcuts.

Is there a GitHub Copilot alternative that works offline?

Continue.dev with Ollama running locally works fully offline — once models are downloaded, no internet is required. Cline with Ollama also works offline. Tabnine Enterprise supports self-hosted deployment for air-gapped environments. None of the managed cloud tools (Codeium, Cursor, Windsurf) work offline.
