Quick Summary: The Best Free Options
| Tool | Type | Best For | Truly Free? |
|---|---|---|---|
| Cursor (Free Tier) | AI IDE | Beginners and general coding | Limited — 2,000 completions/mo |
| Cline | VS Code Extension | Agentic coding in VS Code | Yes (bring your own API key) |
| Aider | Terminal Tool | Git-integrated pair programming | Yes (bring your own API key) |
| Continue | VS Code/JetBrains Extension | Customizable AI in your editor | Yes (bring your own API key) |

Tier 1: Best Free AI Coding Experience
Cursor Free Tier
What you get for free: 2,000 code completions per month, 50 slow premium requests (GPT-4/Claude), unlimited access to the Cursor Tab feature.
The honest take: Cursor's free tier is the best starting point for anyone new to AI coding. The editor itself is excellent — it's built on VS Code, so everything feels familiar — and the AI features work well even on the free tier. 2,000 completions per month sounds limiting, but for learning and small projects, it's usually enough.
The catch: Once you hit the completion limit, you're stuck waiting for the next month or paying $20/month for Pro. Heavy coding sessions can burn through the limit in a few days.
Best for: Beginners, students, anyone who wants to try AI coding without commitment.
GitHub Copilot Free Tier
What you get for free: 2,000 code completions per month and 50 chat messages per month in VS Code, JetBrains, and other editors.
The honest take: GitHub expanded Copilot's free tier significantly, making it a viable option for light use. The inline completions are solid — not as context-aware as Cursor's, but reliable and fast. The biggest advantage is editor flexibility: Copilot works in VS Code, JetBrains IDEs, Neovim, and more.
The catch: The 50 chat messages per month is very restrictive. If you rely on AI chat for debugging or explanations, you'll hit the limit quickly. The completions are inline-only — no agentic capabilities.
Best for: Developers who already use VS Code or JetBrains and want simple inline completions.

Tier 2: Open Source — Truly Free, Unlimited
These tools are completely free and open source. The trade-off: you need to bring your own API key from an AI provider (Anthropic, OpenAI, etc.), which costs money per use. But the tools themselves are free, and you can also use free local models.
Cline (Free, Open Source)
What you get: A VS Code extension with full agentic capabilities — it can create files, edit code, run terminal commands, and even browse websites. Works with any AI provider.
The honest take: Cline is the most capable free tool on this list. Its agentic workflow (step-by-step task execution with your approval) brings Cursor-level AI capabilities to standard VS Code. The quality depends entirely on which AI model you connect it to — Claude 3.5 Sonnet gives the best results.
The cost catch: Cline is free, but your API key isn't. Using Claude 3.5 Sonnet costs roughly $5-15/day with active use. However, you can use DeepSeek ($0.10-0.50/day) or free local models via Ollama for zero cost.
Best for: VS Code users who want powerful agentic AI without switching editors.
Aider (Free, Open Source)
What you get: A terminal-based AI pair programming tool with excellent git integration. Every AI change is automatically committed with a descriptive message.
The honest take: Aider is the best tool for developers who live in the terminal. Its git integration is unmatched — clean commits, easy undo, full history. It supports 20+ AI models and can even use free local models through Ollama.
The cost catch: Same as Cline — you need an API key. But Aider has an edge: it works particularly well with DeepSeek, which is very affordable. And its /run command for sharing terminal output with the AI is uniquely efficient at reducing token usage.
Best for: Terminal-first developers who want AI-integrated pair programming.
Continue (Free, Open Source)
What you get: AI autocomplete, chat, and code actions in VS Code and JetBrains. Highly customizable — choose your models, configure your workflow.
The honest take: Continue is the most flexible option. It works with essentially any AI provider, supports VS Code and JetBrains (not just VS Code), and gives you granular control over how AI integrates into your workflow. The autocomplete isn't as refined as Copilot's, but the chat and code actions are solid.
The cost catch: Same API key situation. Continue's autocomplete feature can be configured to use smaller, cheaper models while reserving expensive models for chat — a smart cost optimization.
Best for: Developers who want maximum control and flexibility in their AI setup.

Tier 3: Free Tiers for App Building
If you're not a developer and want to build something, these browser-based tools have free tiers:
Bolt Free Tier
What you get: Limited generations to build web applications from text descriptions.
The honest take: Bolt's free tier is good enough to try it out and build one or two simple prototypes. But it's very limited — you'll hit the generation cap quickly if you're iterating on a project.
Best for: Quick experiments to see if text-to-app tools work for your idea.
Replit Free Tier
What you get: A cloud IDE with basic AI assistance and limited compute resources.
The honest take: Replit's free tier is the best option for absolute beginners who want everything in one place — editor, terminal, hosting, and AI. The free tier is restrictive on compute but sufficient for learning.
Best for: Complete beginners who don't want to install anything.

The Zero-Cost Setup: Run Local Models
If you want completely free AI coding with no API costs, you can run AI models locally on your computer:
What You Need
- A computer with at least 16GB RAM (32GB preferred)
- A decent GPU (NVIDIA with 8GB+ VRAM, or Apple Silicon Mac)
- Ollama installed (free, one-command install)
How It Works
- Install Ollama:
curl -fsSL https://ollama.com/install.sh | sh - Download a coding model:
ollama pull deepseek-coder-v2orollama pull codellama - Connect to Cline, Aider, or Continue — all support Ollama as a provider
Is It Any Good?
Honestly: Local models are impressive for their cost (free) but noticeably less capable than Claude 3.5 Sonnet or GPT-4o. They work well for:
- Simple code generation and autocomplete
- Explaining code
- Basic refactoring
They struggle with:
- Complex multi-file tasks
- Understanding large codebases
- Nuanced debugging
Our recommendation: Start with local models if cost is a hard constraint. If you can afford $5-10/month on API costs, a cloud model through Cline or Aider will be significantly more productive.
How to Choose: Decision Flowchart
Are you a complete beginner? → Yes → Cursor free tier (best beginner experience) → No → Continue below
Do you use VS Code? → Yes → Cline (agentic AI in VS Code) or GitHub Copilot free tier (simple completions) → No → Continue below
Do you use the terminal heavily? → Yes → Aider (git-integrated, terminal-native) → No → Continue below
Do you use JetBrains? → Yes → Continue (works in JetBrains and VS Code) → No → Cursor free tier (best all-around)
Cost Comparison: What "Free" Actually Costs
| Tool | Tool Cost | API Cost | Total Monthly |
|---|---|---|---|
| Cursor Free | $0 | $0 | $0 (limited) |
| Copilot Free | $0 | $0 | $0 (limited) |
| Cline + DeepSeek | $0 | ~$3-15 | ~$3-15 |
| Aider + DeepSeek | $0 | ~$3-15 | ~$3-15 |
| Continue + Ollama | $0 | $0 | $0 (local) |
| Cline + Ollama | $0 | $0 | $0 (local) |
The cheapest path to unlimited, decent AI coding: Continue or Cline + Ollama with a local model = $0/month.
The cheapest path to unlimited, excellent AI coding: Cline or Aider + DeepSeek = ~$3-15/month.
Our Honest Recommendation
For most people, here's what we'd suggest:
-
Start with Cursor's free tier. It's the most polished experience and requires zero setup beyond downloading the app.
-
When you hit the limit, switch to Cline + an API key. Cline in VS Code gives you more powerful agentic features than Cursor's free tier, and you pay only for what you use.
-
If you're cost-sensitive, add Ollama. Use a local model for simple tasks (autocomplete, explanations) and save your API budget for complex tasks.
-
If you're a terminal person, try Aider. It's genuinely great and the git integration alone is worth it.
The AI coding tool space moves fast. We'll update this guide as tools release new free tiers and open-source options improve.
