# ECC vs bitchat

ECC and bitchat share 3 technologies: Tokio, tracing, and tracing-subscriber. ECC is written in Rust and bitchat in Swift.

- [affaan-m/ECC](https://seerepo.com/r/affaan-m/ECC): The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
- [permissionlesstech/bitchat](https://seerepo.com/r/permissionlesstech/bitchat): bluetooth mesh chat, IRC vibes

## What they share and what sets them apart

- In common: Tokio, tracing, tracing-subscriber
- Only in ECC: Express, rusqlite, SQLite, sql.js, Anthropic, OpenAI, crossterm, Ratatui, fal-client, scenedetect, js-yaml, Ajv
- Only in bitchat: None

## Side by side

| | ECC | bitchat |
|---|---|---|
| Size | 399,193 lines written, 256 code files | 164,838 lines written, 318 code files |
| Who writes it | 8.7% of its commits signed by AI. With Claude Code, GitHub Copilot, Codex, Cursor, CodeRabbit, and Devin | 21.8% of its commits signed by AI. With Claude Code and Cursor |
| Activity | Last push November 9, 2026, 3,584 commits, 301,356 stars | Last push November 1, 2026, 975 commits, 37,082 stars |
| Tests | 465 test files. 36.7% of its code files have a test that imports them | 239 test files. 81.1% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
