Analyze Your Software DNA.

Bomly is a free, open-source CLI for dependency intelligence. It scans source trees, SBOMs, Git refs, and container images; explains why dependencies are present; enriches packages with vulnerability and license data when you ask for it; evaluates policy; and writes automation-friendly output for CI.

Free and open source, no account, no login. One binary. No service to host. No telemetry. No outbound matcher calls unless you opt in with `--enrich`. [Network and Privacy](docs/NETWORK.md) documents every network trigger so you can audit that claim instead of taking it on faith.

## Install Bomly

```bash
# macOS / Linuxbrew
brew install bomly-dev/tap/bomly

# Linux / macOS install script
curl -fsSL https://bomly.dev/install.sh | sh

# Windows
winget install Bomly.BomlyCLI
```

Prebuilt archives and Linux packages are published from [GitHub Releases](https://github.com/bomly-dev/bomly-cli/releases). Releases include `bomly` (full binary with builtin Syft and Grype) and `bomly-lite` (smaller binary that shells out to external `syft` and `grype`).

Verify the install:

```bash
bomly version
```

For Linux packages, Scoop, Go install, checksums, pinned versions, upgrades, and uninstall instructions, see [Installation](docs/INSTALLATION.md).

## Start With a Scan

```bash
# Scan the current project
bomly scan

# Scan a specific directory
bomly scan --path ./services/api

# Scan a container image
bomly scan --image ghcr.io/example/app:latest

# Scan a remote Git ref
bomly scan --url https://github.com/owner/repo --ref v1.2.3

# Read an existing SPDX or CycloneDX SBOM
bomly scan --sbom --path ./sbom.cdx.json
```

Bomly reads manifests, lockfiles, package-manager output, container layers, or existing SBOMs and turns them into one dependency graph. Native detectors cover Go, npm, pnpm, Yarn, Maven, Gradle, Python, Composer, Bundler, GitHub Actions, SBOM ingest, and more. Syft fills the long tail, including container images. See the [Support Matrix](docs/SUPPORT_MATRIX.md) and [Scan Targets](docs/SCAN_TARGETS.md).

## What Bomly Can Answer

| Question | Command |
| --- | --- |
| What do we depend on? | `bomly scan` |
| What changed in this PR or branch? | `bomly diff --base main --head HEAD` |
| Why is this package here? | `bomly explain lodash` |
| Which findings matter to policy? | `bomly scan --enrich --audit --fail-on high` |
| Can CI fail on high-severity findings? | `bomly scan --enrich --audit --fail-on high --format sarif` |
| Can I triage reachable findings first? | `bomly scan --enrich --audit --analyze --fail-on high --fail-on reachable` |

For more recipes, see [Getting Started](docs/GETTING_STARTED.md) and
[Use Cases](docs/USE_CASES.md). To review the public inputs, commands, expected
results, and limitations behind important behavior claims, see
[Reproducible Evidence](docs/EVIDENCE.md).

## Explore Interactively

Open the terminal UI when you want to inspect a graph by hand:

```bash
bomly scan --interactive
```

Use it to fuzzy-find packages, inspect versions and scopes, pivot through findings, and see how a dependency entered the graph without writing a report to disk. See [Interactive TUI](docs/TUI.md).

## Enrich and Audit

By default, Bomly does not call vulnerability, license, lifecycle, or scorecard services. Add `--enrich` when you want external package intelligence:

```bash
# Fetch vulnerability and license data
bomly scan --enrich

# Evaluate policy against enriched package data
bomly scan --enrich --audit --fail-on high

# Add experimental reachability analysis
bomly scan --enrich --audit --analyze --fail-on high --fail-on reachable
```

Built-in enrichment uses public services such as OSV, CISA KEV, deps.dev, and OpenSSF Scorecard. `--audit` evaluates the vulnerability and license data already present on packages; use `--enrich --audit` when you want to fetch and evaluate in one run.

Reachability is experimental. It is useful for triage, but "unreachable" is not a guarantee of safety. Read [Reachability](docs/REACHABILITY.md) before using `--fail-on reachable` as a CI gate.

## Explain and Diff

Use `explain` when a transitive package shows up and you need the path:

```bash
bomly explain requests
bomly explain lodash --path ./web
```

Use `diff` when you need to review dependency changes across Git refs or SBOMs:

```bash
# Compare Git refs
bomly diff --base main --head HEAD

# Compare two SBOM files
bomly diff --sbom --base ./old.spdx.json --head ./new.spdx.json
```

See [Getting Started](docs/GETTING_STARTED.md) for the first-run walkthrough and [Use Cases](docs/USE_CASES.md) for PR review, upgrade review, and incident triage recipes.

## Generate Output for CI

Bomly can write human-readable text, JSON, SARIF, SPDX 2.3, and CycloneDX 1.7:

```bash
# Structured JSON for automation
bomly scan --json

# SARIF for security tabs and code-scanning integrations
bomly scan --enrich --audit --fail-on high --format sarif

# Write SBOM artifacts (add --format text to also print the report)
bomly scan -o spdx=sbom.spdx.json -o cyclonedx=sbom.cdx.json

# Emit one SBOM to stdout
bomly scan --format cyclonedx
```

Exit codes are stable for scripts: `0` for clean results, `2` for policy violations, and separate values for usage, runtime, and no-supported-project failures. See [Output Formats](docs/OUTPUT_FORMATS.md), [SBOM Formats](docs/SBOM.md), and [Exit Codes](docs/EXIT_CODES.md).

To gate pull requests, use the [Bomly Guard action](https://github.com/bomly-dev/bomly-guard) or call the CLI directly from your workflow:

```yaml
# .github/workflows/bomly.yml
- uses: actions/checkout@v5
  with:
    fetch-depth: 0
- uses: bomly-dev/bomly-guard@v1
  with:
    fail-on: high
```

See [Bomly Guard](docs/BOMLY_GUARD.md) and [CI Integration](docs/CI_INTEGRATION.md).

## Use Bomly With AI Agents

Bomly can run as a local MCP server so AI agents can call the same dependency graph tools you use on the command line:

```bash
bomly mcp serve
```

If you have not installed the CLI, the `bomly-mcp` npm wrapper starts the same server:

```bash
npx -y bomly-mcp
```

Add Bomly to an MCP-aware agent such as Claude Code, Cursor, VS Code, or a custom tool, and the agent receives structured JSON it can summarize or reason over. See [MCP Server](docs/MCP.md) for setup recipes and the tool reference.

## Configure and Extend

Bomly reads configuration from your user config, an explicitly selected
config file, `BOMLY_*` environment variables, and CLI flags, with later
sources taking precedence:

1. `~/.bomly/config.yaml`
2. `--config <path>` or `BOMLY_CONFIG`
3. `BOMLY_*` environment variables
4. CLI flags

Repository config files are never loaded automatically. A project may keep
its shared configuration at `.bomly/config.yaml`, but you must trust it
explicitly with `--config .bomly/config.yaml` or `BOMLY_CONFIG`. See the
generated [Config Reference](docs/CONFIG_REFERENCE.md).

Managed plugins let you add detectors, matchers, and auditors without forking Bomly:

```bash
bomly plugins install github:bomly-dev/bomly-plugin-bun-lock-detector@v0.1.0
bomly plugins enable bomly.examples.detector.bun-lock
bomly plugins verify bomly.examples.detector.bun-lock
```

See [Plugins](docs/PLUGINS.md) for install, trust, and authoring guidance.
