100% Local CPU Execution

Every parse, token count, and skeleton synthesis runs directly on your machine's CPU via native C/Wasm Tree-sitter bindings. No code is transmitted to any cloud API.

Zero-Loss Interface Guarantees

Coding agents need exact signatures, generics, and exported interfaces to write correct code. SiftrCode dissolves the internal bodies while keeping 100% of the contracts agents rely on.

Standard Stdio MCP Protocol

No proprietary background daemons or closed network proxies. SiftrCode integrates through the open Model Context Protocol (MCP) using standard Unix pipes.
