Sita

Sita is an open-source platform designed to automate and streamline the process of maintaining up-to-date documentation and onboarding developers within codebases. The platform analyzes repositories by cloning and parsing code, extracting functions, types, classes, and variables, and unifying cross-references across languages using techniques such as AST parsing and SCIP. Sita then builds a topologically sorted dependency graph of the codebase, enabling users to visualize how different components relate and impact each other, from databases to user interfaces.

Documentation is generated automatically in topological order, with summaries for each file or definition that include purpose, dependencies, and usage. This approach allows dependent components to inherit precise context, resulting in more accurate and useful documentation. Sita renders these docs in a minimal React-based UI, featuring Markdown and React Flow graphs for easy navigation, allowing both new and experienced team members to quickly understand complex systems. The platform also supports auto-refresh on pushes to the main branch and uses incremental parsing with Merkle tree/hash diffing to update only changed parts, making it suitable for large monorepos.

Sita integrates with MCP-compatible tools and agents, such as Codex, Claude Code, Cursor, Cline, Warp, Amp, Jules, Factory, RooCode, Aider, Gemini CLI, Kilo, OpenCode, Phoenix, and Zed, among others. The platform includes an agent named Martin, which navigates repositories, summarizes context, pinpoints files and functions to change, and performs parallel searches with citations. Sita optimizes AI usage by sending only relevant, cited code as context, reducing token consumption by 40–60% and potentially lowering costs. Features in development include advanced graph traversal and early detection of cascading changes.

Delivery options include a free, open-source self-hosted tier, allowing users to run Sita locally or on-premises with full control over their data. A managed business offering is available via waitlist, providing hosting, analytics, enhanced suggestions, and support, while an enterprise tier adds SOC 2 compliance, on-prem deployment, SSO/SAML, and priority support. Sita is positioned as a tool for developers and engineering teams seeking to automate documentation, improve onboarding, and maintain secure, consistent codebases.
