About this codebase
Rain is a BitTorrent client that ingests torrent metadata and download targets (e.g., .torrent files or magnet links/trackers), runs protocol interactions through a layered session (tracker/DHT/PEX/webseeds, handshakes, piece selection, and resource management), and outputs persistent resume state plus the assembled files while exposing a JSON-RPC 2.0 control surface and an interactive console UI. In practice, developers or operators use `rain` to start the server, add torrents, monitor progress, and control downloads via CLI or RPC; if no config is present, Rain uses defaults with the default config location `~/rain/config.yaml`.

248 files and 1,536 symbols in 4 modules, written in Go.
Code health
This codebase scores 6.9 out of 10 for code health, which we rate fair. It also scores maintainability 7.8 and static performance 9.9 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 2 of 248 files are git hotspots, and they average 5.2 — which is where the fixes pay off most.

Improve what Repowise can see
Add a test coverage report
Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.
- line coverage
- Unknown, no report
Small effort
Use cenkalti/rain in your agent
Point Claude Code, Cursor, Codex or VS Code at this repository. Your agent gets the index this page is built from: cited answers, callers, history and health for any file.

🌧 BitTorrent client and library in Go This page is a map of the cenkalti/rain repository, written primarily in Go, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 248 files and 1,536 symbols in 4 modules, led by Go. Code health is 6.9 out of 10, rated fair.
