I pay for Claude Pro and Cursor. They’re worth it for me. But when junior devs on my team ask what they should use, I don’t always tell them to spend $40/month on AI tools — especially early in their career when they’re still learning what these tools are good at.

Here are 5 free AI coding tools that are genuinely useful. Not “free tier with a 3-message daily limit” free — actually usable for real daily work.

1. Codeium (Free Copilot Alternative)

What it is: AI code autocomplete that works in VS Code, JetBrains, Vim, and about 40 other editors.

Why it’s good: Codeium’s free tier gives you unlimited autocomplete with no daily limits. The completions are solid — not quite Copilot-level, but close enough that you won’t miss Copilot for most tasks. It handles Python, TypeScript, Java, Go, and most popular languages well.

What I like:

  • Actually unlimited — no “you’ve used your 10 completions today” nonsense
  • Supports almost every editor
  • The completions are context-aware (it reads your open files)
  • Chat feature included for free

Where it falls short:

  • Completions occasionally lag, especially on larger projects
  • The chat isn’t as good as Claude or ChatGPT for complex questions
  • Multi-file awareness isn’t as deep as Cursor’s

Best for: Developers who want Copilot-style autocomplete without paying $19/month. If you’re a student or early-career developer, this should be your first stop.

2. Claude Free Tier

What it is: Anthropic’s Claude, accessible at claude.ai with no subscription.

Why it’s good: The free tier gives you access to Claude 3.5 Sonnet — which is a genuinely capable model for coding tasks. You get a reasonable number of messages per day (it varies, but usually enough for a few solid coding sessions).

What I like:

  • Claude’s code quality is excellent even on the free tier
  • The 200K context window is available to free users
  • Great for code review, debugging, and generating tests
  • More honest about its limitations than most models

Where it falls short:

  • Daily message limits mean you can’t use it all day
  • No API access on the free tier
  • Rate limits tighten during peak hours
  • No access to Opus (the most powerful model)

Best for: Developers who need a high-quality coding AI for specific tasks rather than all-day use. I’d pair this with Codeium — Codeium for autocomplete, Claude free for the harder problems.

Pro tip: Structure your prompts carefully so you get what you need in fewer messages. My prompt engineering patterns work great for maximizing free tier value.

3. GitHub Copilot Free Tier

What it is: GitHub’s AI coding assistant, now with a free tier for all developers.

Why it’s good: GitHub launched a free tier in late 2025 that gives you limited completions per month. It’s not unlimited, but it’s enough to get a feel for AI-assisted coding and to use it for the tasks where it helps most.

What I like:

  • Deeply integrated with VS Code and GitHub
  • The completions are high quality (powered by GPT-4o and Claude)
  • Works well for boilerplate and repetitive patterns
  • Free tier includes Copilot Chat

Where it falls short:

  • The monthly completion limit means you need to be strategic about when you use it
  • Not available in all editors (VS Code and JetBrains primarily)
  • Chat is decent but not as good as using Claude or ChatGPT directly

Best for: Developers already in the GitHub/VS Code ecosystem who want to try AI coding tools before committing to a paid plan.

4. Phind

What it is: AI-powered search engine specifically designed for developers.

Why it’s good: Phind combines web search with AI to give you coding answers with sources. Unlike ChatGPT or Claude, it actively searches the internet, so its answers about libraries, APIs, and current best practices are up-to-date.

What I like:

  • Answers include source links so you can verify
  • Great for “how do I do X in framework Y” questions
  • Understands coding context better than general search
  • The free tier is generous — no message limits for basic queries

Where it falls short:

  • Code generation isn’t as good as ChatGPT or Claude
  • Sometimes pulls from outdated Stack Overflow answers
  • The AI reasoning is shallower than dedicated LLMs for complex problems
  • UI can feel cluttered compared to a clean chat interface

Best for: Replacing your “Google → Stack Overflow → copy paste” workflow. It’s faster and gives you more context. I still use Perplexity for general research, but Phind is better for pure coding questions.

5. Continue (Open Source AI IDE Extension)

What it is: An open-source alternative to Cursor and Copilot that runs in VS Code or JetBrains.

Why it’s good: Continue lets you bring your own model — connect it to a local Ollama instance, a free API tier, or any OpenAI-compatible endpoint. You get autocomplete, chat, and inline editing, all for free if you’re running a local model.

What I like:

  • Fully open source — no vendor lock-in
  • Bring any model: local (Ollama/llama.cpp), Claude API, GPT API, or others
  • The chat and autocomplete UX is clean
  • Active development community

Where it falls short:

  • Setup takes effort — not a “install and go” experience
  • Running local models requires decent hardware (16GB+ RAM)
  • The out-of-box experience isn’t as polished as Cursor
  • Model quality depends on what you connect to

Best for: Developers who want full control over their AI tools, privacy-conscious teams, or anyone with a powerful machine who wants to run models locally. Pair it with CodeLlama or DeepSeek Coder for a solid free setup.

The Free Stack I’d Recommend

If I were starting fresh with zero budget:

  1. Editor autocomplete: Codeium (unlimited, good quality)
  2. Complex coding questions: Claude free tier (best reasoning)
  3. Quick searches: Phind (coding-focused, current answers)
  4. Power users: Continue + local model (full control, zero cost)

Total cost: $0/month. You’d lose some quality and speed compared to paid tools, but you’d still have a genuinely useful AI-assisted workflow.

When to Upgrade to Paid

You should consider paying when:

  • You hit free tier limits regularly (Claude, Copilot)
  • You need Cursor’s project-wide indexing and Composer
  • You need consistent all-day availability without rate limits
  • Your time is worth more than the subscription cost

For most developers earning a professional salary, $20-40/month in AI tools pays for itself in the first week. But if you’re a student, hobbyist, or just getting started — the free stack above is more than enough.
