Repowise

Repowise is a coding tool. Repowise indexes a repository once and refreshes it on every commit, giving coding agents context over MCP and showing teams the blast radius, risk and health of a change before merge. Open source and self-hostable.

Repowise is a codebase intelligence tool that reads a repository once and keeps its index current on every commit. The index joins code structure, git history, tests and recorded decisions, so the same evidence can answer questions about how the code works, what a change will affect and which files deserve attention next. The analysis itself makes no LLM calls, and the project is open source and self-hostable. The tool is aimed at developers who work with coding agents and at engineering teams that review a lot of machine-written changes. Agents such as Claude Code, Cursor and Codex connect over MCP and can ask for answers with cited sources, architecture views, the reasoning behind a piece of code, risk for a planned edit, health scores and security checks. Pull requests get a single bot comment listing affected callers, untested paths and a risk score, and the bot stays quiet when a change is clean. A VS Code extension shows file health in the status bar, blast radius from the source-control panel and decisions on hover, while a dashboard presents architecture, owners, hotspots and health as one system view. In practice, setup is a pip install followed by an init command, then a serve command to expose the index to agents. Documentation pages are rebuilt from the latest commit, and a hosted option lets visitors paste a repository URL instead. Public repositories can be explored without an account, with live examples such as React and LangChain available to browse. The site publishes benchmark figures, including a 0.74 bug-prediction AUC across 21 repositories and 31.6 percent fewer agent tokens on a pinned Django commit. Among alternatives, Repowise sits between code search tools, static analyzers and AI documentation generators. Its distinguishing choice is a persistent, deterministic index shared by agents, reviewers and editors, rather than a separate chat assistant bolted onto the repository.
