# Codeward vs Fallow

> Fallow sweeps dead code. Codeward guards every pull request.

Fallow is a free Rust-native CLI for JavaScript and TypeScript codebase health. Codeward is a hosted or self-hosted multi-agent platform. They overlap on dead code, and complement each other well.

## The short version

Use Fallow if you want a free, instant, local tool to find unused files, exports and dependencies, circular imports, duplication and complexity in a JS/TS codebase. Use Codeward if you want PR-time review across security, runtime, architecture and compliance, with sandbox execution and merge gating. Running both is reasonable: Fallow locally and in CI, Codeward on PRs.

## What Fallow does

Rust-native, zero-config, dead code, circular dependencies, duplication, complexity, architecture boundary rules, auto-removal command, GitHub Action with SARIF, editor and agent integrations.

## What Codeward does

Guardian plus 8 analyzers; bloat is one of them.

## Feature comparison

| Feature | Fallow | Codeward |
| --- | --- | --- |
| Unused files, exports, dependencies | ✔ core strength | ✔ 18 bloat checks (Tree-sitter AST) |
| Circular dependencies | ✔ | ✔ architecture agent |
| Code duplication | ✔ | ✔ AST-based |
| Complexity hotspots | ✔ | ✔ |
| Speed on a laptop | ✔ very fast, local | Slower; boots a sandbox |
| Cost | ✔ free CLI | ✔ self-host free; cloud priced |
| Auto-remove dead code | ✔ built-in command | Suggested diffs |
| Languages | JavaScript and TypeScript only | Broader; confirm list |
| Security scanning | ✕ | ✔ |
| Runtime and flaky tests | ✕ | ✔ |
| AI-era and compliance checks | ✕ | ✔ |
| PR comments and merge gate | Via GitHub Action and SARIF | ✔ native Check Run |
| AI reasoning about findings | ✕ deterministic analysis | ✔ |
| Works offline / no code leaves machine | ✔ | ✔ if self-hosted |

## Honest take

Fallow is excellent at its narrow job. Its output is deterministic and fast, which makes it a great fit for pre-commit hooks and CI. A Fallow report on an AI-written repo will usually find dead exports and duplicates quickly.

Codeward is not a faster Fallow. Its value starts where static graph analysis ends: security, runtime failures, architecture and compliance. A practical setup is Fallow for cheap local hygiene and Codeward for PR-time depth.

## Pricing

Fallow: free, open source. Codeward: open source, with managed cloud at [codeward.cloud](https://codeward.cloud).

## Frequently asked questions

### Why not just use Fallow?

If dead code and duplication are your only problems, you probably should. Add Codeward when you also need security, runtime and compliance coverage.

### Do they conflict?

No. Fallow runs locally or in CI; Codeward runs on PR events.

### Does Codeward auto-remove dead code?

It reports bloat with suggested diffs. Automated one-click refactoring PRs are on the roadmap.

## Bottom line

Fallow cleans the yard. Codeward guards the gate.
