Introduction
If you're a developer looking to speed up routine coding, debug faster, or prototype features more quickly, there's never been more choice. In this final episode of our Tool Showdown series (Episode 5 of 5), I rundown the top 7 free AI coding tools you can use today. As we covered in earlier episodes — like our Cursor vs Claude Code piece and the GitHub Copilot vs Cursor deep-dive — each assistant has trade-offs. Here you'll find a practical, up-to-date list (as of 2026-02-27) with features, limitations, best-use cases, and how to get started.

6) Visual Studio IntelliCode
Features
- Built into Visual Studio and VS Code (as an extension), providing AI-assisted completions tuned to common patterns and open-source models.
- Helps with API usage recommendations, signature help, and style-consistent suggestions.
- Free to use within supported editors.
Limitations
- Less conversational than chat-based assistants — it's completions-first.
- Works best inside the Microsoft ecosystem; cross-platform parity is improving but variable.
Best for
- .NET, C#, and TypeScript developers using Visual Studio or VS Code who want native, free AI completions.
How to get started
- Ensure you have VS Code or Visual Studio updated to the latest release.
- Enable IntelliCode (builtin or install the extension).
- Open your project and accept recommended completions as you type.
7) LocalAI + StarCoder (open-source local option)
Features
- LocalAI is an OSS runtime that runs open-source LLMs locally; StarCoder (or other code-focused open models) provides free, community-trained code generation.
- Full control over data privacy and no vendor lock-in.
- Good for experimenting with custom prompts and pipelines without ongoing subscription costs.
Limitations
- Requires local hardware or cloud VM with sufficient RAM/VRAM for medium/large models.
- Setup and model management need more technical know-how than SaaS offerings.
Best for
- Developers and teams who need offline, private code generation and want to run models without a cloud fee.
How to get started
- Install LocalAI (Docker image or binary) on your machine or VM.
- Download a compatible model like StarCoder from Hugging Face (watch licensing and size).
- Configure the LocalAI endpoint and connect it to an editor plugin (several community plugins exist for VS Code and Neovim).

How to choose the right free tool for you
- If you need zero-setup, start with Codeium or IntelliCode (they’re quick to enable).
- If you work heavily with AWS, try CodeWhisperer for AWS-aware suggestions.
- For repo-aware answers, Sourcegraph Cody is ideal.
- If privacy and offline use are critical, LocalAI + StarCoder is the go-to.
- If you qualify (student or OSS maintainer), GitHub Copilot can be the most contextually powerful free option.
Final tips
- Always review AI-generated code for bugs, security, and license issues. These tools accelerate work — they don't replace review.
- Combine tools (e.g., LocalAI for offline prototyping + Copilot for GitHub-enabled features) depending on project phase.
- Keep sensitive keys and secrets out of prompts and code snippets you send to cloud tools.
As this series closes, remember to revisit Episode 1 and Episode 4 if you’re deciding between Cursor, Copilot, or Claude Code; earlier episodes cover deeper head-to-heads that pair well with the free-tool recommendations here. Try a couple of these free options in small, low-risk projects and pick the assistant that fits your workflow.
