No vendor lock-in in AI coding tools means you can move your code, data, model access, and working process to another setup without losing essential access or rebuilding the workflow from zero. It is a matter of practical portability, not a slogan.
Assess portability across the whole system:
- Code: Changes remain in your repository using ordinary branches, commits, and diffs.
- Context: Project instructions, plans, and rules can be exported in readable formats.
- Models: You can change providers or credentials without redesigning every task.
- Automation: Tests, scripts, and deployment steps work outside the product.
- History: Important decisions and review evidence are available without a closed interface.
- Billing: Leaving the service does not trap an essential balance or block repository access.
Some switching cost is normal. Each agent has different tools, prompts, and context behavior. Lock-in becomes a concern when proprietary project state cannot be exported, core checks only run inside one product, or changing models requires rebuilding the entire process.
Reduce risk by keeping source code, tests, architecture notes, and acceptance criteria in systems you control. Use standard repository workflows and test a small exit path before committing a critical project. A portable setup should let another developer or agent understand the current state and continue safely.
Choose tools based on present value, but preserve an operational way out. The strongest evidence of low lock-in is a successful migration test, not a feature-page claim.
