AI Coding Tools
If source code may not leave your network, most of this category is unavailable to you regardless of how good it is. These run inside your own infrastructure: Tabnine as a supported commercial product with air-gapped deployment, JetBrains on its enterprise tier, and Cline pointed at a locally hosted model if you have the platform capability to run one. Expect a step down in output quality against the frontier-model tools — that is the trade, and for regulated buyers it is not a close call.
Best for regulated and air-gapped environments where code cannot leave the network
Tabnine sells to the buyer whose first question is not "how good is it" but "where does our code go". It is the most complete answer in this category for air-gapped and heavily regulated environments, at a price that reflects that.

Best free agent, and the most transparent one for reviewing every step
Cline is a VS Code extension that gives you agent-level capability without a subscription: you supply an API key, it supplies the agent. The permission-per-step design makes it the most transparent agent we tested, and the most reviewable.

Best for teams committed to IntelliJ, PyCharm and the JetBrains IDEs
JetBrains AI is the answer for the very large population of developers who are not going to leave IntelliJ or PyCharm. It is the only assistant here built on a real static-analysis engine, and it shows in refactoring work.
