Coding agent with a deep codebase context engine for IDEs and CLI.
Context engine shines on large codebases; usage-based credits can add up.
4.A

18.B
Kilo Code
Open-source coding agent for VS Code/JetBrains/CLI with provider-rate inference.

Owns-your-stack alternative to vendor cloud agents; young product.
