Best Free AI Coding Assistant in 2026 โ€” Self-Hosted Alternatives to Copilot


GitHub Copilot costs $10-19/month. Claude Pro costs $20/month. You can get 80-90% of the same experience for free by running an AI coding model locally. Here are the best options in 2026.

Update (April 24, 2026): DeepSeek V4 Flash is nearly free at $0.28/1M output tokens. See V4 Flash cheapest frontier model.

The best free setups

1. Continue + Ollama + Qwen 2.5 Coder 32B (best quality)

The gold standard for free coding assistance. Qwen 2.5 Coder 32B scores 88.4% on HumanEval โ€” matching GPT-4o.

Requirements: 24GB VRAM (RTX 4090) or 32GB Mac Setup time: 10 minutes

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Download the model
ollama run qwen2.5-coder:32b

Then install the Continue extension in VS Code, set provider to Ollama, model to qwen2.5-coder:32b. Done.

You now have:

  • Inline code completion (tab to accept)
  • Chat sidebar for code questions
  • Code explanation and refactoring
  • Test generation
  • All running locally, zero data sent anywhere

2. Continue + Ollama + Codestral (best autocomplete)

Codestral scores 95.3% on FIM โ€” the best autocomplete model available, including paid ones.

Requirements: 16GB VRAM or 16GB Mac Setup time: 10 minutes

ollama run codestral

Codestral is specifically optimized for fill-in-the-middle, which is the task that powers inline suggestions. If autocomplete quality is your top priority, this beats Copilot.

Note: Codestralโ€™s license restricts commercial use. For personal and open-source projects, itโ€™s fine.

3. Continue + Ollama + Qwen3.5-9B (budget option)

If you donโ€™t have a powerful GPU, Qwen3.5-9B runs on 8GB and still provides useful coding assistance.

Requirements: 8GB VRAM or 16GB Mac/laptop Setup time: 5 minutes

ollama run qwen3.5:9b

Not as good as the 32B Coder model, but it handles code completion, explanation, and simple generation well enough for daily use.

4. Continue + Ollama + DeepSeek Coder V2 Lite (coding specialist)

DeepSeek Coder is trained specifically on code and supports 338 programming languages.

Requirements: 12GB VRAM Setup time: 5 minutes

ollama run deepseek-coder-v2:16b

Good choice if you work with niche languages that other models struggle with.

The main advantage of Copilot is multi-file context awareness and seamless integration. The main advantage of self-hosted is privacy and zero cost.

The optimal free setup

Use two models:

  1. Codestral for autocomplete โ€” best FIM model available
  2. Qwen 2.5 Coder 32B for chat, code review, and generation

In Continueโ€™s config, set Codestral as the autocomplete model and Qwen Coder as the chat model. This gives you the best of both worlds.

FAQ

Whatโ€™s the best free AI coding assistant in 2026?

Continue.dev with Ollama running Qwen 3.5 27B locally is the best fully free setup โ€” it gives you autocomplete, chat, and inline editing with no subscription. For cloud-based free options, DeepSeekโ€™s free tier and Qwenโ€™s API free tier are excellent.

Is there a free alternative to GitHub Copilot?

Yes. Continue.dev + Ollama + Codestral 22B gives you Copilot-level autocomplete for free. It runs locally, requires no subscription, and your code stays private. The setup takes about 5 minutes.

Are free AI coding assistants good enough for professional work?

For most daily tasks (autocomplete, boilerplate, simple refactors), free tools are 85-90% as good as paid alternatives. The gap shows on complex multi-file tasks and architectural decisions where frontier models like Claude Opus still have an edge.
