codna

Codna is a code intelligence tool designed to analyze and repair software repositories using autonomous agents. It addresses the challenge of understanding large codebases and rapidly fixing issues by mapping the entire repository's structure, dependencies, and potential impact areas in milliseconds without consuming tokens. This deterministic mapping enables Codna to provide agents with a focused evidence bundle, minimizing the amount of context required to diagnose and resolve bugs.

The platform supports over 250 programming languages, including Python, TypeScript, Go, Rust, Java, C, Swift, Kotlin, Ruby, PHP, JavaScript, C++, Scala, Dart, Elixir, Haskell, SQL, Zig, Lua, and Julia. Codna operates by parsing the repository into a dependency and blast-radius graph, identifying suspect files, and assembling a minimal set of relevant code for the agent to act on. Each fix is simulated for blast radius and risk before being applied, and the system's custom on-device memory engine, Telys, ensures that relevant code context is recalled efficiently across sessions. Codna's approach results in significantly reduced token usage and faster performance compared to traditional agent-based solutions, as demonstrated in benchmarks across public repositories.

Codna integrates into existing engineering workflows through a command-line interface, a GitHub app, or as an MCP server. It can be installed locally via pip or deployed on the user's own infrastructure or cloud, ensuring that code remains private and is never sent externally without explicit authorization. The tool is designed with privacy and security in mind, featuring per-tenant key isolation, secret redaction, and audited egress, with no training performed on user code.

04 per verified fix. Codna is positioned as a solution for engineering teams seeking automated, reliable, and privacy-focused codebase understanding and repair, particularly for large or complex repositories.
