About this codebase
`repo` is a Phoenix/Elixir real-time backend that ingests client and tenant requests, routes them through the realtime application layer (including database access and telemetry), and serves interactive LiveView pages plus API endpoints as runtime artifacts (HTML/LiveView state, JSON responses, and logged/telemetry events).
Written by gpt-5.4-nano from the index
585 files and 19 symbols in 9 modules, led by Elixir (445 files) and JavaScript (3).
Code health
This codebase scores 8.4 out of 10 for code health, which we rate good. It also scores maintainability 9.9 and static performance 10.0 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 50 of 585 files are git hotspots, and they average 6.5 — which is where the fixes pay off most.
Do next
Nothing stands out in the week to Jul 9, the last indexed commit.
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 supabase/realtime 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.
https://api.repowise.dev/mcp/supabase/realtimeOne command, run anywhere. Adds the server to your local Claude Code config.
Docsclaude mcp add --transport http repowise https://api.repowise.dev/mcp/supabase/realtime \ --header "Authorization: Bearer rw_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
This repo is public, so anyone with a Repowise account and an API key can connect.
Try asking
- get_overview()
- get_answer("how is realtime put together?")
- get_why("why is realtime structured this way?")
Prefer local? pip install repowise && repowise init indexes your own checkout, no account needed.

Repowise badge
Links to this page, with no score on it. Adding it also re-indexes the repo every week.
[](https://repowise.dev/repo/supabase/realtime?src=badge_wiki)Code health badge
The repo's health score out of 10, from the latest index.
[](https://repowise.dev/repo/supabase/realtime?src=badge_health)Code health card
A larger card with the score, its change since the last index, and when it was measured. The HTML version follows the reader's light or dark theme.

Broadcast, Presence, and Postgres Changes via WebSockets This page is a map of the supabase/realtime repository, written primarily in Elixir, 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 585 files and 19 symbols in 9 modules, led by Elixir, JavaScript and Shell. Code health is 8.4 out of 10, rated good.
