Fix bugs in any language.
The deterministic graph doesn't care what you write in — 130 repos across 110 languages mapped in 9.2 seconds, measured.
Languages
Fix Python bugs
Dynamic imports, decorators, and duck typing make Python quick to write and hard for an agent to trace. Codna is an AI Python pair programmer that builds the dependency graph deterministically first, so the fix starts from facts about your code, not guesses from a token budget.
Fix TypeScript bugs
Barrel files, path aliases, and deep generic inference scatter a single bug across a TypeScript project. Codna resolves the real module and type graph deterministically, so this AI TypeScript debugging starts from facts and hands the agent exactly the files that matter.
Fix Go bugs
Implicit interface satisfaction, goroutines, and channels scatter a Go bug across packages with no single line to blame. Codna builds the dependency graph deterministically in about 60ms for zero LLM tokens, so the Go AI bug fix starts from facts, not guesses.
Fix Java bugs
Interfaces, dependency injection, and deep inheritance hierarchies scatter a Java bug far from where it surfaces. Codna is an AI Java debugging tool that builds the dependency graph deterministically, so the fix starts from facts about your code, not guesses.
Fix Rust bugs
Ownership, trait resolution, and lifetimes scatter a Rust bug across crates and impl blocks. Codna is an AI Rust pair programmer that builds the dependency graph deterministically — for zero LLM tokens — so each fix starts from facts, not a guess.
Fix JavaScript bugs
Async timing, mixed CommonJS and ESM, and no compiler to catch a typo scatter a JavaScript bug across files. Codna is an AI coding agent that resolves the real module and call graph deterministically, so the fix starts from facts, not guesses.
Fix Ruby bugs
Metaprogramming, mixins, and method_missing make Ruby a joy to write and hard for an agent to trace. Codna is an AI Ruby pair programmer that builds the dependency graph deterministically, so every fix starts from facts about your app, not guesses.
Fix PHP bugs
Magic methods, service-container wiring, and dynamic calls make PHP fast to write and hard for an AI to trace. Codna builds the dependency graph deterministically, so your AI PHP debugging starts from facts, not guesses.
Fix C# bugs
Generics, async/await, and deep namespaces scatter a C# bug across projects and NuGet packages. Codna is an AI C# pair programmer that builds the dependency and blast-radius graph deterministically, so the fix starts from facts, not guesses.
Fix C++ bugs
Header includes, template instantiations, and a sprawling CMake build make C++ bugs hard for an agent to trace. Codna is an AI C++ pair programmer that builds the dependency graph deterministically, so each fix starts from facts, not guesses.
Fix Kotlin bugs
Coroutines, extension functions, and sealed-class hierarchies make Kotlin expressive to write and hard for an agent to trace. Codna builds the dependency graph deterministically, so an AI Kotlin bug fix starts from facts about your code, not guesses.
Fix Swift bugs
Optionals, protocol conformances, and Swift Concurrency scatter a single bug across an iOS or server-side project. Codna resolves the type and call graph deterministically, so AI Swift debugging starts from facts, not guesses, and hands the agent exactly the files that matter.
