Which one won't shit the bed during my demo?

**Codeium** has been solid for 8+ months across VS Code updates. The free tier hits limits now but still works for light usage. **Continue.dev** is open source so you can fix it yourself if it breaks, but that also means you might have to. **Bito** works consistently but the interface feels clunky.

What actually happens when the "free tier" runs out?

**Codeium** - You hit credit limits and have to wait for them to refill or upgrade to Pro ($15/month). They switched to credits... was it February? March? Sometime early this year when they killed the unlimited tier. **Continue.dev** - It's open source, so nothing to run out of. **ChatGPT/Claude** - You hit rate limits and have to wait or pay, but no IDE integration anyway.

Which one works in corporate environments without breaking security policies?

**Tabnine** - Self-hosted, code never leaves your network. Setup is a pain but IT will approve it. **Amazon Q Developer** - If you're already on AWS, security team probably trusts it. **GitHub Copilot** - Microsoft ecosystem, most enterprises already vetted it.

Which one won't train AI models on my company's secret sauce?

**Tabnine** - Explicit promise not to use your code for training, plus self-hosting. **Codeium** - Also promises not to train on your code. Free tier includes this guarantee. **Continue.dev** - Open source, you control everything including which models to use.

Which one actually suggests code that doesn't suck?

**Cursor** - Best context awareness but you have to switch editors. **Codeium** - Matches Copilot accuracy, faster responses, free. **GitHub Copilot** - Still solid, especially for popular languages like Python/JavaScript.

Do any of these actually work with my weird programming language?

**Codeium** - 70+ languages, though quality varies. Python/JS are great, Rust is okay, Erlang suggestions are garbage. **GitHub Copilot** - Best for mainstream languages, struggles with niche ones. **Continue.dev** - You can plug in specialized models for specific languages.

Can I run multiple AI assistants without them fighting each other?

Yes, but it's weird. **Codeium** for autocomplete + **ChatGPT** for complex problems works fine. **Continue.dev** lets you switch between different models for different tasks. Just disable conflicting autocomplete features or you'll get competing suggestions.

How much of a pain is it to switch from Copilot?

**Codeium** - Install extension, works immediately. Same shortcuts, similar interface. **Amazon Q Developer** - Easy if you already have AWS CLI configured. Otherwise, authentication hell involving Builder ID, IAM roles, and policy JSON that will eat your entire weekend. Spent a Saturday night reading AWS IAM docs instead of having a life. Amazon Q is region-picky as hell. Spent a weekend debugging "Resource not found" errors before realizing it only works in certain regions. March last year, I think? Still pissed about wasted time. **Cursor** - Complete workflow migration. Plan for a week of "where the fuck is this feature?" followed by your team complaining about lost productivity. Plus you'll inevitably hit some random bug that makes you question your life choices at 2am while trying to deploy a hotfix. Happened to us last month - debugging a prod issue while fighting with a new editor is not fun.

What's the cheapest option that doesn't suck?

**Codeium** - Free tier with credit limits. Still decent for light usage, Pro is $15/month for heavy users. **Continue.dev** - Open source, completely free, but you're on your own for support. **Bito** - Free tier covers most use cases for small teams.

Will this work with my ancient IDE?

**Tabnine** - Supports 15+ IDEs including ancient ones. **VS Code/JetBrains** - Most tools support these. **Vim/Emacs** - Codeium and Continue.dev have extensions. **Eclipse/NetBeans** - You're mostly screwed, try Tabnine.

Which ones promise not to steal my code?

**Tabnine** - Explicit no-training guarantee, self-hosting available. **Codeium** - Still promises not to train on user code, even in free tier. **Continue.dev** - Open source, local models, you control everything. **Amazon Q Developer** - AWS privacy standards, which are pretty solid.

Which one won't make my team hate me for forcing them to switch?

**Codeium** - Least disruptive, works in existing IDEs, free tier keeps everyone happy. Nobody complains about free shit that just works. **GitHub Copilot** - If it ain't broke and budget allows, don't fix it. Your team already knows it. **Cursor** - Prepare for rebellion unless the entire team is willing to learn a new editor. I tried this once and got three resignation threats. This might not happen to you but good luck.

GitHub Copilot Chat Alternatives: AI-Optimized Technical Reference

Executive Summary

Cost Comparison: 15-person team paying $285/month ($3,420/year) for GitHub Copilot Business vs alternatives ranging from free to $30/month per user.

Critical Decision Factors:

Budget constraints (accounting approval at scale)
Security/compliance requirements (code leaving premises)
Language/framework support quality
Migration complexity and team productivity impact

Configuration and Pricing

Tool	Monthly Cost	Free Tier Limits	Enterprise Options
GitHub Copilot	$10 Pro / $19 Business / $39 Enterprise	None	Full enterprise features
Codeium/Windsurf	Free - $15/month	Credit-based limits (changed early 2024)	Pro tier available
Cursor	$20 Pro / $40 Teams	Limited free usage	Team collaboration features
Amazon Q Developer	$19/month	Limited free tier	AWS integration
Tabnine	$12-39/month	Basic free tier	Self-hosting available
Continue.dev	Free	Fully open source	Self-managed

Critical Implementation Warnings

Security and Compliance Failures

Code Training Risk: Most tools train on user code unless explicitly disabled
Data Exfiltration: Regulated industries require self-hosted solutions
Silent Failures: Amazon Q fails silently with missing IAM permissions

Production-Breaking Suggestions

GitHub Copilot: Suggested eval() for JSON parsing in authentication service
Language Quality Variance: Python/JavaScript excellent, niche languages poor
Context Confusion: Large files (500k+ lines) cause degraded suggestions

Authentication and Network Issues

Proxy Hell: Corporate proxies break most tools, requiring IT intervention
IAM Complexity: Amazon Q requires 15+ specific permissions, fails silently
Region Dependencies: Amazon Q only works in specific AWS regions

Resource Requirements

Time Investment

Codeium: 30 seconds (unless proxy issues = 3 hours)
Cursor: 1 week minimum for full migration
Amazon Q: Weekend lost to IAM configuration
Tabnine: Enterprise setup complexity varies significantly

Expertise Requirements

Basic Setup: VS Code extensions work immediately
AWS Integration: Requires IAM policy expertise
Self-Hosting: DevOps/security team involvement needed
Migration: Complete workflow retraining for editor switches
