Alternatives to Codeium
Free AI code completion and chat for many editors.
5 hand-curated alternatives from MintedSaaS's directory. See the Codeium listing →
Codeium is a free AI code completion tool that works across most editors and IDEs, from VS Code to JetBrains to Vim. It offers both real-time inline suggestions and a chat interface for asking questions about code. The product targets individual developers and small teams who want AI-assisted coding without paying per-seat, and it's particularly popular among open-source contributors and students. Codeium runs cloud-hosted models, so there's no local inference required, though the company emphasizes that code isn't stored for training.
Developers typically use Codeium to speed up routine coding tasks—boilerplate, variable names, completing function signatures—and to ask follow-up questions via chat when they're stuck. It fits workflows where speed matters but the team hasn't committed to a paid solution like GitHub Copilot, or where developers want a lighter-weight alternative. The comparison-shopping visitor here is usually checking whether Codeium's free tier genuinely covers their use case, or whether another tool offers better accuracy, faster responses, or tighter integrations with their primary IDE.
What we offer that competes

What to look for
- Whether the tool runs completions locally or requires cloud inference and an active internet connection.
- Whether code you write is used for model training and how to opt out of code retention.
- Which IDE and editor integrations are available and how deeply the tool is integrated versus an extension.
- Whether there is a free tier and what limits apply to inference calls, message history, or feature access.
- Whether the product publishes a documented API for custom integrations or only offers pre-built extensions.
- Whether the tool supports chat-based code generation alongside inline completion suggestions.
FAQ
What are the best alternatives to Codeium?
The most direct competitors are GitHub Copilot (paid, deeply integrated into VS Code and GitHub), Cursor (a fork of VS Code with AI baked in), Tabnine (free tier available, strong on accuracy), and Replit (browser-based IDE with built-in AI). Each prioritizes different workflows: Copilot for enterprise teams, Cursor for developers who want AI-first editing, Tabnine for accuracy-conscious users, and Replit for learning and rapid prototyping.
Are there free alternatives to Codeium?
Yes. Tabnine offers a free tier with basic completion, and Replit's free plan includes its AI assistant for code generation and chat. GitHub Copilot requires a paid subscription but offers a 60-day trial. Cursor has a free trial but then requires payment. For zero-cost ongoing use, Codeium and Tabnine's free plans are your main options.
Which AI code completion tools work in VS Code?
Codeium, GitHub Copilot, Tabnine, and Cursor all support VS Code. Cursor is actually a standalone VS Code fork with AI features integrated at the editor level, so the experience feels the most native. Codeium and Copilot work as extensions. Replit is web-based and doesn't extend VS Code, but it offers a full IDE with AI in the browser.
How do I choose between code completion and code generation tools?
Completion tools (Codeium, Copilot, Tabnine) suggest the next few characters or lines as you type. Generation tools let you describe what you want in English and get back full functions or classes. Most modern tools do both, but they emphasize one. If you spend more time typing repetitive code, go with completion; if you sketch in comments and want the AI to fill in logic, prioritize generation.
Do I need internet access for AI code completion to work?
Codeium, Copilot, and Tabnine all rely on cloud inference, so yes—you need an internet connection. Cursor also sends queries to a cloud model by default. Some tools can run smaller local models, but the quality is typically lower. If you need offline-only completion, you'll need older, rule-based tools rather than modern AI assistants.
Can AI code assistants see my proprietary code?
Most tools claim they don't train on or retain your code, but the policy differs. Codeium explicitly says code isn't logged for training. GitHub Copilot has an opt-out (Business plan includes it by default). Tabnine also offers code privacy controls. Cursor and Replit use third-party models under the hood. Always review the privacy policy for your specific tool before pasting sensitive code.
What platforms do code completion tools support?
Codeium supports VS Code, JetBrains IDEs, Neovim, Vim, Sublime Text, and others. GitHub Copilot covers VS Code, JetBrains, and Neovim. Tabnine has the broadest IDE coverage. Cursor is VS Code-only (it's a fork). Replit is browser-based and language-agnostic. Pick based on which editor you use most; if you work across multiple, Tabnine or Codeium are safer bets.
Can I use an AI code tool if my company forbids cloud processing?
Not with most mainstream tools. Codeium, Copilot, and Tabnine all use cloud inference. GitHub Copilot Business offers some data governance controls, but processing still happens on Microsoft's servers. If your company requires everything to stay on-premise, you'll need to run a local model (with lower accuracy) or negotiate an enterprise arrangement with the vendor.
