The "Just Sign Up and Start Coding" Bullshit
Remember when Slack promised instant productivity? Same bullshit here. These AI tools demo great - developers autocompleting like magic in 30 seconds.
Reality? I spent 4 months just getting GitHub Copilot approved. Four. Fucking. Months. And that was at a tech company, not some bank with 50 approval committees.
Here's what actually happens:
Months 1-3: Security Hell
Your CISO will lose their shit about sending code to external APIs. Questionnaires longer than mortgage applications. Data residency costs extra - we spent maybe 15k on that alone? Plus legal arguing about liability for like a month.
Months 4-6: Integration Nightmare
That seamless demo integration? Bullshit. Doesn't work with VPN. Doesn't work with corporate firewall. Our custom build system? Forget about it. DevOps spent like 6 weeks fighting with proxy settings.
Wait, actually, I think it was longer than that. Maybe 8 weeks? Time blurs together when you're debugging enterprise networking bullshit.
Months 7-9: Nobody Uses It
Half the team thinks AI will replace them (paranoid). Other half uses it wrong (creates more bugs). That vendor webinar training? Complete joke. Had to bring in consultants for real training - easily 2k per dev who actually learned it.
What This Stuff Really Costs (And I Mean Really)
GitHub Copilot Enterprise: That $39/Month Lie
At my last company we had like 480 developers, maybe more. Here's roughly what we spent (I think - accounting was weird):
Licenses were around 225k annually? Could've been 240k, I don't remember exactly. But that's just the start. Security review took forever and cost us... shit, maybe 35k for consultants? SSO integration was a nightmare - their SAML is garbage - probably another 20-30k to fix.
Training was the real killer. Had to bring in outside people because their webinars suck. Maybe 60k? Could've been more.
First year total was around 350k I think. Way more than the original quote, whatever that was.
Amazon Q Developer: "Custom Pricing" = Bend Over
"Custom pricing" means they figure out your budget and charge 90% of it. Demo worked great. Production? Eh, not so much.
We only tried this with our AWS team (like 50 people). Started at 19/month but talked them down to maybe 16? Implementation was "free" which means it's hidden in your AWS bill somewhere.
Works fine if you're AWS-only. But we have stuff on GCP and Azure too, and Q doesn't give a shit about those. Integration was a pain.
Actually, I'm not even sure we're still using it. Haven't checked in a while.
Tabnine On-Premise: Didn't Try This One
To be honest, we looked at Tabnine but never pulled the trigger. On-premise sounded good to our security team but the setup looked like a nightmare.
From what I heard from other companies, you need a whole K8s cluster just for this thing. Plus a full-time engineer to babysit it. One guy told me they spent like 200k just on setup? Could be exaggerating.
Security team loved the idea of keeping everything internal, but DevOps said "fuck no" to managing another cluster. So we passed.
Why This Takes Forever
Security Reviews From Hell
Our CISO was convinced GitHub was gonna leak our code to competitors. Spent 4 months on questionnaires and "risk assessments." They wanted 50 different compliance docs that GitHub didn't have.
Eventually approved it but with like 20 restrictions that broke half the features.
Everything Breaks
Nothing works out of the box. Had to build custom IntelliJ plugins - took our team maybe 6 weeks? Integration with our code review system was another nightmare.
SSO broke every few weeks. Still not sure why.
Oh, and WSL2? Forget about it. Broke constantly. M1 Macs had some weird issue too but I forget what it was.
Training Is Expensive
Vendor training is useless - just product demos basically. Had to bring in consultants for real workshops. Cost us like 2k per person who actually bothered to show up.
Half the team skipped it anyway. Still fighting to get people to use these tools 8 months later.
Getting People to Actually Use This Stuff
Even after spending like 300k or whatever on implementation, maybe 40% of our developers actually use these tools regularly. The ones who do seem to like them, but getting there was a pain in the ass.
Everyone Fights About It
Senior developers think AI suggestions are garbage. Junior developers trust them way too much and stop thinking for themselves. Your team lead's gonna bitch that "AI code doesn't follow our standards." Just plan for lots of arguments.
Everything Breaks Your Workflow
Code reviews get weird when half the team is using AI and half isn't. Your style guides become pointless. Debugging becomes a nightmare when you don't understand the code that got generated. Documentation written by people who've never used the product.
It Gets Old Fast
The initial "holy shit this is amazing" productivity boost disappears after a few months when people figure out where the tool sucks. Those fantasy 40% productivity improvements vendors love to talk about? More like 15% in reality, if you're lucky.
Look, Just Budget Way More Than They Tell You
These AI coding tools can be worth it, but the pricing is designed to get you hooked before you realize what you're actually paying. Every single deployment I've seen ends up costing at least double the original quote, sometimes triple.
If your budget is 100k, tell your CFO it's gonna be 250k minimum. If they freak out about that, maybe wait another year - these tools aren't disappearing, and maybe the vendors will stop playing pricing games eventually (though I doubt it).
Once You Pick One, You're Pretty Much Stuck
Switching between these tools once you're deployed is expensive as hell. I know companies that spent like 200k just trying to migrate from one tool to another. The vendor lock-in is no joke.
GitHub Copilot Trap
If you're already on GitHub Enterprise, Copilot works great. But say you want to switch to Cursor later? Everything breaks. Your code review setup, GitHub Actions, security scans - it all gets fucked up. We figured it would take maybe 6 months and like 300k to fully get away from Copilot. So we didn't.
Amazon Q Keeps You Locked to AWS
Amazon Q is fine if your whole world is AWS. But the second you need to work with Google Cloud or Azure, you're screwed. I know one company that spent something like 150k, maybe more, building custom stuff just to make Q play nice with their multi-cloud setup. Timeline was like 6 months, could've been longer.
Multiple Tools = Multiple Headaches
Some companies think they're being smart using different tools for different things - GitHub for frontend, Tabnine for backend, Amazon Q for DevOps or whatever. Sounds clever until you realize you now have three times the compliance bullshit, three times the security reviews, three times the training programs, and developers who have no clue which tool to use for what.
What Enterprise Plans Actually Get You
Yeah, enterprise stuff costs like 2-3x more than individual plans. Sometimes it's worth it, sometimes you're getting robbed.
GitHub Copilot Enterprise at 39 bucks
Good stuff: SSO actually works, audit logs don't suck, they'll cover your ass legally if something goes wrong. Bad stuff: Data residency costs extra, and you need GitHub Enterprise for the good features which is another 21 per seat or something.
Amazon Q's "Custom Pricing"
If you're all-in on AWS, the integration is pretty smooth. But "custom pricing" basically means they're gonna charge you 3x whatever the published rate is if you have any real budget.
Tabnine Enterprise
Good for paranoid security teams who want everything on-premise. But you'll spend like 100k just keeping the infrastructure running. Maybe more.
Getting Better Pricing (If You're Lucky)
Volume discounts exist but vendors make you jump through hoops. With 500+ developers you might get 10-15% off if you threaten to go elsewhere. 1,000+ developers and custom pricing becomes possible, but expect months of negotiations. 5,000+ developers? Now you have some real leverage, but they'll want multi-year contracts.
The trick is actually piloting 2-3 tools with real developers, not just comparing feature lists. Vendors hate competitive deals but they'll negotiate when they think you might actually walk away.
What You'll Really Get Out of This
Forget those bullshit 3,000% ROI calculations vendors love. Recent industry studies show the real numbers are way more modest. Here's what actually happens:
First few months: Pretty much zero productivity improvement while everyone figures out how to use it. Next few months: Maybe 20-30% improvement for the boring stuff. After that: 15-20% improvement once the novelty wears off. Long term: Probably 10-15% sustained improvement.
Interestingly, some research found that experienced developers using AI tools actually took 19% longer than without - so results vary wildly. Gartner predicts 75% of enterprise developers will use AI assistants by 2028, but other research shows developers save 10 hours a week with AI but lose 10 hours to organizational inefficiencies.
Is it worth it? Yeah, probably. But don't expect these tools to magically turn your junior developers into senior engineers overnight.
