codanna vs CALM

codanna: Codanna provides 'X-ray vision' for AI code assistants, enabling them to understand code structure, trace relationships, and find implementations with precision. It facilitates context-first coding, eliminating the need for manual searching and speeding up R&D and pair programming workflows.; CALM: CALM (Coding Agent Liveness Map) provides AI coding agents with a live, graph-verified map of the codebase, enabling them to understand dependencies and structural relationships before making changes. This ensures safer and more accurate code edits, preventing common pitfalls like breaking call sites or critical components due to lack of visibility.

Features

codanna logocodanna
01Semantic Search: Natural language queries against code and documentation.
02Relationship Tracking: Generate call graphs, find implementations, and analyze dependencies.
03Document Search (RAG): Index markdown and text files for RAG workflows alongside code.
04MCP Protocol Integration: Native integration with Claude, Gemini, Codex, and other AI assistants.
CALM logoCALM
01Real-time, Graph-Verified Codebase Map: Provides full call graphs for 13 languages out of the box (24 languages parsed in total), showing actual dependencies rather than similarity guesses.
02Hard Safety Gates on Write Path: Enforces hash-verified and syntax-checked edits, with hub/high-risk symbols requiring explicit confirmation and review of callers before changes are committed.
03Confidence-Graded Call Edges with Compiler Verification: Call edges are confidence-graded (textual → inferred → resolved → formal), with SCIP/LSP overlays upgrading best-guess edges to compiler-verified ground truth for 12 languages.
04Automated Codebase Health Reporting: Generates fitness reports based on metrics like hub concentration, dead code rate, complexity, and architectural boundary violations, queryable mid-session or enforceable in CI.
05Local-First and Privacy-Preserving Operation: Runs entirely on your machine with no code leaving for indexing or editing, using an MIT license and vendored embedding models for offline use.

Use Cases

codanna logocodanna
↳Instantly find where a function is called and trace its call graph.
↳Semantically search for specific logic like 'authentication flow' based on intent, not just keywords.
↳Analyze full dependencies to understand the impact of code changes.
↳Query project documentation (RAG) alongside code for comprehensive context.
↳Accelerate rapid R&D and pair programming by providing instant, structured code understanding.
CALM logoCALM
↳Empowering AI agents to safely refactor and edit code directly, by providing a deep understanding of code dependencies and impact.
↳Ensuring code quality and architecture compliance in CI/CD pipelines, by automatically flagging dead code, high-complexity functions, and boundary violations.
↳Onboarding developers to new codebases or areas by offering an interactive, live map of the project's structure and hotspots.
↳Facilitating secure and validated code modifications within various IDEs and AI client environments, preventing unintended breakages.
