Is switching from GitHub Copilot actually worth it?

For most teams, **fuck no**. I've watched too many teams spend months migrating just to end up back on Copilot after realizing the grass wasn't greener. Only switch if Copilot can't do something you legitimately need - like air-gapped deployment or specific model requirements. The subscription cost difference is meaningless compared to what migration actually costs.

How much does migration really cost?

Way more than you think. For a 15-developer team like ours, plan on $20k-40k in real costs beyond subscription differences. That includes time spent retraining developers, fixing configuration issues, dealing with productivity drops, and all the administrative bullshit of switching vendors. Most teams budget just the subscription difference ($15/month extra) and end up spending 100x that.

How long does migration actually take?

2-4 months to get back to baseline productivity, 6-12 months to see if it was worth it. Anyone who tells you "it's just a few days of adjustment" is lying or has never done a real migration. Unlearning muscle memory takes time, and every AI tool works differently enough to reset your productivity.

Which tool is cheapest to migrate to?

The cheapest migration is not migrating. But if you're determined to do it anyway, Windsurf probably has the lowest switching costs since it's more similar to Copilot's workflow. Cursor costs more due to credit overages. Claude Code changes your terminal habits. Tabnine is expensive as hell but works if you need air-gapped deployment.

Can we run GitHub Copilot and alternatives at the same time?

Technically yes, but it's like using two different keyboards. Developers will pick their favorite and ignore the other, so you're just paying twice for the same productivity. During migration, keep Copilot as a fallback for a few months, but don't plan to run both long-term.

What's the biggest mistake teams make during migration?

Expecting developers to adapt in a week or two. The biggest migrations I've seen fail all had the same problem: management expected instant results. Reality: it takes 1-2 months to stop fighting with the new tool and 3-6 months to actually get good at using it. Plan for the productivity hit or don't migrate.

Should startups waste time on this?

Hell no. Startups should be building product, not optimizing development tools. The money you'd spend on migration ($20k-30k for a small team) could pay for an additional developer for months. GitHub Copilot Pro ($10/month) or Business ($19/month) is dirt cheap compared to the opportunity cost of migration.

How do you know if migration worked?

Don't track "AI tool usage" or other vanity metrics. Track what matters: Are you shipping features faster? Are developers happier? Are customers getting better products? If you can't answer those questions positively after 6 months, your migration failed.

What if developers are pushing for a switch?

Listen, but stay skeptical. If your senior developers can demonstrate significant improvements on real work (not demos), consider a small pilot. But if it's just "this tool seems cooler" or FOMO about the latest AI trend, help them get better at using Copilot instead of switching tools.

How do credit systems fuck with your budget?

Credit-based pricing is designed to be unpredictable. Cursor's credits can disappear fast during large refactors - I've seen developers burn through $120 in a week with no warning. Claude Code rate-limits you into expensive tier upgrades. GitHub Copilot's fixed pricing starts looking pretty good when you're dealing with surprise bills.

Can big companies negotiate better deals?

Maybe on subscription costs, but that's not where the real expense is. Vendors might offer migration assistance for large teams, but they won't pay for your internal productivity losses, training time, or integration work - which is 80% of your actual migration cost.

What if we need air-gapped deployment?

Tabnine Enterprise is basically your only option for true air-gapped deployment. Continue.dev can be self-hosted but good luck finding someone with the expertise to manage it properly. Everything else (Copilot, Cursor, Claude Code) sends your code to cloud services.

How do we handle the productivity crash?

Plan for developers to be 20-40% slower for 1-2 months. Tell stakeholders upfront that sprints will be slower, pair people who know the new tool with those learning, and keep Copilot licenses active for critical deadlines. Teams that don't plan for this get surprised when deadlines slip.

Are these smaller AI tool companies stable enough to bet on?

GitHub Copilot has Microsoft backing, so it's not going anywhere. Smaller companies like Cursor and Windsurf could get acquired, change pricing models, or pivot. If you want boring stability, stick with the market leader. If you're willing to bet on a smaller player, just know the risk.

How long until migration pays off?

If it works at all, 12-18 months to break even. Teams that expect ROI in 3-6 months always fail because the learning curve and integration costs take longer to overcome than expected. Budget for at least 18 months if you're serious about this.

How do you avoid getting locked into a tool?

GitHub Copilot has the least lock-in since it works with standard VS Code and established patterns. Cursor and Windsurf require their custom IDEs. Claude Code changes your terminal workflows. Continue.dev has no lock-in but good luck managing it yourself.

Should we wait for the next great AI tool?

No. The market is pretty settled at this point. Waiting for the "perfect" tool means missing out on productivity improvements available today. Plus, migration costs increase the longer you wait as teams build more processes around their current tool.

What if migration fails halfway through?

Have a backup plan. Keep Copilot licenses active, document what's not working, and be willing to cut your losses. I've seen teams waste months trying to force a failed migration instead of rolling back to what worked.

How do we convince management not to migrate?

Show them the real cost. Migration for a 20-person team costs $30k-50k minimum. Ask if that money would be better spent on hiring another developer, improving infrastructure, or actually building product features. Usually the answer becomes obvious.

What's the most important thing to know about migration?

The subscription price difference doesn't matter. Migration costs are 10-50x the subscription savings. If you're migrating to "save money," you're going to spend way more than expected. Only migrate if Copilot literally can't do something you need.
