A fast, read-only code analysis instrument for your terminal.
Count lines of code, detect languages and frameworks, and generate clean reports -- all without touching a single file in the target project.
DevRadar is a command-line tool that scans any project directory and produces a detailed breakdown of:
- Lines of code -- total, code-only, comments, and blanks
- Programming languages -- detected from file extensions
- Frameworks and libraries -- parsed from manifest files (package.json, requirements.txt, go.mod, Cargo.toml, and more)
- Build tools, package managers, and databases -- identified from config files and dependencies
It is designed to be read-only: DevRadar never creates, modifies, or deletes any file in the project being analyzed.
| Category | Details |
|---|---|
| Line Counting | Total lines, pure code (comments and blanks excluded), per-file breakdown |
| Language Detection | 60+ languages via file extension mapping |
| Framework Detection | Node.js, Python, Java, Go, Rust, PHP, Ruby, .NET, Dart/Flutter |
| Monorepo Support | Detect and analyze npm/yarn/pnpm/Lerna workspaces separately |
| Compare Mode | Diff current results against a previous JSON report |
| Remote Analysis | Analyze any public Git repository by URL |
| Interactive Mode | Guided terminal prompts -- no flags to memorize |
| Visual Charts | ASCII bar chart for language distribution |
| Multiple Engines | Auto-selects tokei, cloc, or built-in counter |
| Export Formats | Terminal, JSON, CSV |
| Config File | Project-level defaults via .devradarrc.json |
| Sortable Output | Sort tables by name, lines, code, or file count |

DevRadar auto-selects the best available engine in this order:
| Priority | Engine | Description |
|---|---|---|
| 1 | tokei | Fast, Rust-based (recommended) |
| 2 | cloc | Mature, Perl-based |
| 3 | Built-in | Zero-dependency fallback |
You can force a specific engine with --tokei, --cloc, or --builtin. The active engine is always printed in the report header.
Save a report as JSON, then compare it later to see what changed:
# Save baseline
devradar . -o baseline.json
# ... make changes to the project ...
# Compare
devradar . --compare baseline.jsonOutput shows deltas for files, lines, languages added/removed, and framework changes.
devradar . --monorepoDevRadar detects workspaces from:
package.jsonworkspaces (npm / yarn)pnpm-workspace.yamllerna.json
Each workspace is analyzed separately with an aggregate summary at the end.
Place a .devradarrc.json in your project root to set default options:
{
"pureCode": true,
"sort": "code",
"exclude": ["test/**", "docs/**"]
}CLI flags always take precedence over config file values.
