AI Coding Tools: The Good, The Bad, and The 'Why Did I Install This?'

AI Coding Tools Evolution

GitHub Copilot started this mess in 2021. Now we have 47 different AI tools that all claim to make coding easier but mostly just break your workflow in new and creative ways.

Instead of Stack Overflow, we now argue with robots about semicolons. The tools have genuinely changed how we write code, but not necessarily for the better. Here's the reality of what happened when AI invaded your IDE.

How We Got Here (And Why We Can't Go Back)

GitHub Copilot won because Microsoft shoved it into everyone's VS Code and most developers are too lazy to switch tools. Also, it actually works most of the time, which puts it ahead of 80% of the competition. They've got over 1 million paying subscribers by now, which honestly surprises me given how often it suggests import * from 'lodash' for everything. The official documentation is surprisingly helpful once you get past the Microsoft corporate speak, though their pricing model keeps changing with new usage limits that nobody asked for.

Cursor said "fuck plugins" and rebuilt VS Code from scratch with AI baked in. Smart move, except now you have to migrate your entire workflow. Their recent pricing changes basically doubled costs for heavy users - classic "burn VC money until we figure out pricing" strategy. The Cursor community has been vocal about these changes, and their GitHub issues reveal the growing pains of a rapidly scaling AI-first editor.

Windsurf is the new hotness from the Codeium team, basically their attempt to go from "free alternative" to "real competitor". They're trying to be different with "AI agents" that allegedly write entire features for you. I've used it since the Codeium days - the agent sometimes deletes entire functions and acts like it's helping. Error: Cannot find module './auth/middleware' after the agent "cleaned up" my imports. But when it works, it's genuinely impressive. Still buggy as hell though. The Windsurf documentation details their ambitious vision for autonomous coding.

Claude Code costs more than my rent if you actually use it, but it's scary good at understanding what you're trying to do. Built on Anthropic's Claude 3.5 Sonnet, it actually reads and understands complex codebases. I used it to refactor a 50,000-line monolith and it actually suggested better architecture patterns. Worth it if someone else is paying. The Anthropic documentation explains their approach to code understanding, and their safety principles set them apart from other AI companies.

The Reality Nobody Talks About

Integration Philosophy: Some tools are plugins (Copilot, Codeium) that work with your existing editor. Others (Cursor, Windsurf) force you to use their editor. Claude Code runs in a browser like it's 2010. Pick your poison.

Pricing Models: Windsurf is free-ish until it throttles you at the worst possible moment. GitHub Copilot starts at $10/month until you hit usage limits and suddenly need the $39 plan. Cursor sounds cheap at $20/month until your entire team needs licenses. Claude Code will bankrupt freelancers.

AI Model Strategy: They all use different AI models, which means they're all wrong in their own special ways. GitHub Copilot thinks everything should be jQuery. TypeError: $ is not defined - thanks, Copilot. Cursor wants to import the entire internet. Claude Code writes code like a computer science professor - technically correct but overly complex.

The War Stories: What Actually Happens When You Use These Tools

GitHub Copilot: The Devil You Know

GitHub Copilot VS Code Interface

I've been using Copilot since it came out of beta. Microsoft's recent billing changes were basically "surprise, you hit our invisible usage limit, pay more money." The official documentation tries to explain this, but the community discussions tell the real story of frustrated developers.

The Good: It just works. Installed in 5 minutes, immediately started completing my React components (badly, but confidently). When you're writing boring CRUD operations, it saves hours. The JetBrains integration is solid - slower than VS Code but functional. Enterprise billing dashboard actually helps when your finance team asks why the coding tool bill went from $500 to $2,000 this month. The VS Code integration remains the gold standard for AI coding assistance.

The Shit: Suggests import lodash for everything. Seriously, I wanted to format a date and it pulled in moment.js and three utility libraries. Context window is too small - it forgets what you're doing across files. On large TypeScript projects, it gets confused by your own types and suggests garbage. Oh, and it suggested eval() for parsing JSON. Three times.

War Story: Used Copilot to refactor authentication code. It confidently suggested storing JWT tokens in localStorage with a helpful comment "// TODO: this is secure, right?". That PR sat in review for 3 weeks while security tore me apart. The security documentation mentions this as a common issue, but doesn't emphasize it enough.

Cursor: The Editor Migration Nightmare That's Actually Worth It

Cursor made me migrate my entire VS Code setup. Took like 5-7 hours, felt like forever. Their recent pricing changes basically said "we were losing money, now you pay double." The migration guide exists, but the community forum is where you'll find the real solutions to migration headaches.

The Good: Holy shit, this is what AI coding should feel like. Multi-line suggestions that actually make sense. The chat interface understands your entire codebase, not just the current file. Refactoring across 20 files actually works. When I needed to convert class components to hooks, Cursor did 90% of the work correctly. The Composer feature is magic when it works.

The Bad: Random crashes on Windows (WSL2 PATH issues, classic). Your VS Code extensions don't work anymore. The terminal integration is janky. Occasionally decides to rewrite your entire component in a completely different pattern. Team sync features sound great until someone pushes a change and your AI context gets fucked.

War Story: Used Cursor to build a dashboard component. It generated 200 lines of perfect TypeScript with proper error handling and loading states. Then it decided the component should use Zustand instead of Redux and rewrote everything without asking. Lost 2 hours of work because I trusted the AI too much.

Claude Code: The Expensive Therapist for Your Code

Claude AI Logo

Claude Code costs more than my car payment, but it actually understands software architecture. Built on Claude 3.5 Sonnet or whatever they're calling it now.

The Good: This thing reads code like a senior architect. Asked it to review a 500-line service class, it immediately spotted the circular dependency I'd been debugging for days. Refactoring suggestions are genuinely thoughtful - not just "extract this into a function" but "this violates single responsibility principle, here's how to fix it." Web interface means no setup hell.

The Bad: $200+/month if you actually use it for work. Sessions timeout and you lose context. No IDE integration means copy/paste hell. It writes code like an academic - technically correct but overly complex. Tried to optimize a simple loop, it suggested a functional approach with three higher-order functions.

War Story: Asked Claude to help debug a memory leak in Node.js. It analyzed the code and correctly identified that we were creating closures in a loop without cleanup. Fixed a production issue that had been burning money for months. Worth every penny of that ridiculous bill.

Windsurf: From Codeium's Scrappy Free Tool to... Whatever This Is Now

Windsurf is basically the evolved form of Codeium - they're trying to automate entire coding workflows with AI agents. Their Cascade agent is either brilliant or catastrophic, no middle ground.

The Good: When the agent works, it's like having a junior developer who never sleeps. Asked it to add authentication to a React app, it generated login/signup components, API routes, middleware, and database migrations. Actually understood the existing code patterns and followed them. Multi-file changes that make sense. Was the best deal in AI coding when it was free as Codeium.

The Bad: Still feels like beta software. The agent gets confused and starts deleting functions "to simplify the codebase." ReferenceError: validateUser is not defined - thanks, agent. Future pricing is uncertain since they're trying to monetize now. What was once the reliable free option is in transition.

War Story: Let the Windsurf agent "optimize" my Express API. It decided all my route handlers were too complex and deleted half of them. Spent 4 hours reconstructing the authentication middleware from memory. The agent cheerfully reported "Successfully simplified your codebase! Removed 47 unnecessary functions." I watched this tool evolve from scrappy free alternative to... whatever this business model is supposed to be.

The Bottom Line: Pick Your Poison

Stop waiting for the perfect AI coding tool. They're all flawed in their own special ways:

  • Copilot if you want industry standard + Microsoft enterprise bullshit
  • Cursor if you can handle setup pain for the best experience
  • Claude Code if you have money and want intelligent code review
  • Windsurf if you want free AI coding with agent chaos

The tool matters less than learning to work with AI without losing your ability to actually code. Don't let the robot do all the thinking.

After 6 months of daily use with these tools, I can code faster but I also debug AI-generated bugs that I wouldn't have written myself. The productivity gains are real, but so is the dependency. Choose the tool that breaks your workflow the least, not the one with the slickest marketing.

The Questions Developers Actually Ask

Q

Which tool won't make me hate programming even more?

A

Windsurf (formerly the free Codeium) if you're broke or just starting out, though they'll probably add paid tiers soon. GitHub Copilot if you want something that just works without thinking too hard about it. Cursor if you can handle the migration pain and want the best actual coding experience.

Q

What's the real cost when you factor in productivity loss from debugging AI-generated bugs?

A

Windsurf (formerly Codeium) is still free but they're probably figuring out monetization. GitHub Copilot at $10/month is honest pricing until you hit usage limits and get bumped to $39. Cursor at $20/month is expensive but saves more time than it costs. Claude Code will bankrupt you at $200+/month but prevents more bugs than it creates.

Q

Which one actually understands my codebase instead of suggesting random Stack Overflow snippets?

A

Claude Code with its 200K context window actually reads your entire project and suggests coherent changes. Cursor with 32K context is pretty good at understanding your patterns. GitHub Copilot forgets what you were doing 3 files ago. Windsurf agent sometimes gets it, sometimes deletes your authentication system.

Q

Can any of these work when my internet is shit?

A

Nope. They all need constant internet connection. GitHub Copilot and Windsurf cache some completions, so you might get suggestions for 5-10 minutes offline. The rest just stop working immediately. Plan accordingly if you code on airplanes or have unreliable internet.

Q

Will these tools send my proprietary code to train future models?

A

GitHub Copilot and Cursor let you exclude repos from training (if you trust them). Claude Code says they don't train on user data (Anthropic seems more trustworthy). Windsurf (formerly Codeium) used to offer self-hosted deployment, but those options seem to be disappearing. Read the fine print and assume your code might be seen by humans.

Q

Which tool won't suggest deprecated methods from 2015?

A

Cursor stays relatively current with modern practices. Claude Code understands recent language features well. GitHub Copilot suggests jQuery solutions to React problems because it trained on old GitHub repos. Windsurf varies wildly and is too inconsistent to judge yet.

Q

How badly will these break my existing workflow?

A

GitHub Copilot works as a plugin with your current editor

  • minimal disruption. Windsurf now offers both its own IDE and extensions for VS Code/JetBrains. Cursor requires completely migrating to their editor and all your settings/extensions. Claude Code is a web interface with copy/paste hell. Pick your poison based on how much setup pain you can handle.
Q

Can I run multiple tools without them fighting each other?

A

GitHub Copilot + Windsurf extensions can coexist as plugins (though it's weird having two AI assistants). Editor-based tools (Cursor, Windsurf IDE) require exclusive use. Claude Code runs separately so you can use it alongside anything else for specific tasks like code review.

Q

What happens when I hit usage limits in the middle of a deadline?

A

GitHub Copilot cuts you off and suggests upgrading to Pro+ ($39/month). Cursor bills you for overages. Windsurf throttles you at random times when you need it most. Claude Code gets expensive fast. Keep a backup plan.

Q

Which one has the least annoying learning curve?

A

GitHub Copilot works exactly like existing VS Code

  • zero learning curve. Windsurf extensions are similar. Cursor requires migrating your entire setup but the interface is familiar. Windsurf agent workflow is completely different and takes weeks to feel natural. Claude Code chat interface is intuitive but copy/paste workflow sucks.
Q

Should I trust these things with security-sensitive code?

A

Hell no. They all suggest insecure patterns regularly. GitHub Copilot suggested eval() for JSON parsing. Cursor wanted to store JWT tokens in localStorage. Claude Code is better at explaining why something is insecure, but still suggests questionable code. Use them for productivity, review everything for security yourself.

Q

Which companies actually use these in production?

A

GitHub Copilot is used by Microsoft, Shopify, and other enterprises because it has compliance features. Cursor is popular with YC startups and indie developers. Claude Code usage is harder to track but seems popular with senior engineers for architecture reviews. Windsurf (formerly Codeium) had enterprise customers who wanted on-premises deployment, but that seems to be getting phased out.

Q

How do I know if these are actually making me more productive or just making me lazy?

A

Track your bug reports and code review feedback before/after adoption. If you're shipping faster with similar quality, it's working. If you're creating more bugs or can't explain your own code anymore, dial back the AI assistance. The tool should amplify your skills, not replace them.

Q

What's the migration path if I want to switch tools?

A

From Copilot to Cursor: Export VS Code settings, install Cursor, pray your extensions have equivalents. Budget 4-8 hours.

From Copilot to Claude Code: No migration needed, just use both for different tasks.

From Cursor to anything else: You're probably stuck unless you really hate it.

From Windsurf: If using their IDE, it's migration pain like Cursor. If using their extensions, easy switch to other plugin-based tools.

Q

Should I wait for the next big AI coding breakthrough?

A

No. These tools are useful now despite their flaws. The "perfect" AI coding assistant doesn't exist and probably never will. Pick one that solves your current problems, use it for 6 months, then reevaluate. The landscape changes too fast to wait for perfection.

The real question isn't which tool is perfect, but which imperfect tool makes your daily coding life less frustrating. They're all going to suggest bad code sometimes. The key is finding one that's wrong in ways you can easily spot and fix.
