KI-Agenten.shopAI stack for software teams: selection and pilot
An AI dev stack combines a suitable coding tool with version control, automated tests and human review. Start with a bounded pilot; add subscriptions only when a demonstrated gap requires them.
Which tools belong in the stack?
Cursor, GitHub Copilot and Claude Code overlap in agentic tasks. A separate tool for every phase is not a prerequisite. Choose around your editor, repository, execution environment and team administration. Keep version control, CI and tests as independent foundations.
Cost of the whole workflow
Track active seats, subscriptions, additional model usage, cloud execution, CI, setup and review time. Subscription and API billing are different access paths. Included allowances do not mean unlimited consumption. A low list price alone does not establish the lowest total cost.
Data and permissions
Check training, retention, local logs and optional feedback uploads separately for the exact plan. No training does not mean no storage. Local execution does not mean local model inference. Limit repository, network and write permissions; do not grant blanket access to secrets or production.
Pilot from ticket to merge
Editorial selection guide, not our own performance benchmark. Sources checked on 16 September 2026.
- Define acceptance criteria and the existing test baseline; document comparable tasks without AI.
- Use one tool on an isolated branch with limited permissions and a fixed budget.
- Log changes, failed attempts, usage and manual rework; run the required tests.
- Have a responsible human review the diff and security implications. AI review can supplement this approval, not replace it.
- Compare time to accepted merge, review time, defects and total cost. Expand only with demonstrated benefit; prepare rollback.
Current provider guides
Cursor
Cursor is a standalone code editor with agent features and autocomplete. Check project import, required extensions and your review workflow. Cloud agents use a different execution path from local work; an AI IDE does not replace testing or approval.
GitHub Copilot
GitHub Copilot supports compatible editors, the CLI and GitHub workflows. Check the specific combination of IDE, model, agent feature and plan. It is not limited to autocomplete; agent changes require the same review as other code changes.
Claude Code
Claude Code works on repositories, changes files and runs commands. Terminal, IDE, desktop and web interfaces have different features and execution environments. Check permissions, extensions and CI integration rather than reducing the product to a terminal assistant.
