# fuel-core vs swc

fuel-core and swc share 5 technologies: lru, Tokio, wasmtime, tracing, and tracing-subscriber. Both are written in Rust.

- [FuelLabs/fuel-core](https://seerepo.com/r/FuelLabs/fuel-core): Rust full node implementation of the Fuel v2 protocol.
- [swc-project/swc](https://seerepo.com/r/swc-project/swc): Rust-based platform for the Web

## What they share and what sets them apart

- In common: lru, Tokio, wasmtime, tracing, tracing-subscriber
- Only in fuel-core: tower, axum, aws-sdk-s3, rocksdb, Redis, quick_cache, AWS S3, crossterm, indicatif, termion, ed25519-dalek, parquet, prometheus-client, tracing-appender, tracing-core
- Only in swc: React, lightningcss, antd, dialoguer, yaml, jsonc-parser, prop-types

| Who writes it | 0.7% of its commits signed by AI. With Claude Code and Cursor | 1% of its commits signed by AI. With Claude Code, GitHub Copilot, and Warp |
| Activity | Last push November 5, 2026, 1,513 commits, 56,767 stars | Last push November 6, 2026, 12,405 commits, 34,208 stars |
| Tests | 166 test files. 33% of its code files have a test that imports them | 48,541 test files. 14.3% 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.
