Saoud Rizwan / open source · The Coding-Agent Era
Cline
The VS Code extension that does the work in your editor — read, write, run, browse — with permission gates.
By C.W. Jameson · Published 19 May 2026 · Last reviewed 19 May 2026
Cline is the open-source answer to the question 'what if the coding agent lived inside the editor instead of beside it?' Every file write asks for approval; every shell command is reviewable; every browser action is logged. The result is an agent that's slow to use and easy to trust.
