**Got a “license violation” warning while shipping code?** You’re not alone—developers constantly battle hidden licenses that can stall releases and invite legal risk. This guide gives you a **ready‑to‑use open source license compliance checklist** that lets you spot problems fast, document decisions, and stay ship‑ready without a law degree.

## Why a License Compliance Checklist Is Essential  

A single unexpected GPL dependency can force you to open‑source your entire product. The cost of a missed license isn’t just legal exposure; it’s wasted time, angry stakeholders, and delayed launches. By treating compliance as a repeatable process, you turn a potential nightmare into a quick, repeatable audit.

## The 6‑Step Open‑Source License Compliance Checklist  

### Step 1: Identify All Third‑Party Code  
Run your package manager’s dependency‑tree command (e.g., `npm ls`, `pip freeze`, `mvn dependency:tree`) and **save the output** to a plain‑text file. This inventory is the foundation for every later step.

### Step 2: Catalog the Licenses  
For each entry, pull the license from the package metadata, the project’s README, or the `LICENSE` file. Record the **license name** beside the dependency. If a license is unfamiliar, a quick web search will tell you whether it’s permissive, copyleft, or something else.

### Step 3: Compare Against Your Policy  
Define which licenses your organization accepts (common choices: MIT, Apache 2.0) and which it rejects (e.g., GPL, AGPL). **Mark each dependency** as “OK” or “Not OK” based on that policy. This is where conflicts surface.

### Step 4: Flag Conflicts & Choose an Action  
When a dependency is “Not OK,” you have three paths:  

1. **Swap** it for an alternative with a friendly license.  
2. **Negotiate** a different licensing option with the maintainer.  
3. **Isolate** the code (e.g., run it as a separate service) to avoid copyleft spill‑over.

Document the chosen approach next to the flagged item.

### Step 5: Document Your Resolutions  
Create a short report (Markdown or CSV) that lists each dependency, its license, your decision, and any follow‑up steps (swap, negotiate, isolate). **Commit this report** to your repo so future teammates instantly see the compliance rationale.

### Step 6: Re‑Check on a Regular Cadence  
Dependencies evolve; new versions can introduce new licenses. Set a calendar reminder—**monthly or on every major update**—to rerun the inventory and update the report. A quick scan now prevents a costly surprise later.

## Free Tools That Automate the Checklist  

| Tool | What It Does | Why We Like It |
|------|--------------|----------------|
| **Licensee** (GitHub) | Scans a repo and highlights detected licenses | Lightweight, integrates with CI |
| **FOSSA** (free tier) | Generates a Bill of Materials and flags conflicts | Handles multi‑language projects |
| **ClearlyDefined** | Looks up license info across ecosystems | Great for obscure packages |
| **sbom‑tool** (Microsoft) | Creates a software bill of materials (SBOM) for review | Enterprise‑grade output |

Pick the tool that matches your stack, run it, and feed the results into the six‑step checklist above.

## Quick Reference Checklist (Copy‑Paste)

- [ ] **List every external package** (`npm ls`, `pip freeze`, etc.)  
- [ ] **Record each license** beside the package name  
- [ ] **Compare** against your approved‑license policy  
- [ ] **Flag** non‑compliant items & decide: replace, negotiate, or isolate  
- [ ] **Document** decisions in a repo‑tracked report  
- [ ] **Schedule** recurring checks (monthly or on major updates)  

## Wrap‑Up  

A concise **open source license compliance checklist** removes guesswork, keeps your releases on schedule, and protects both your company and the open‑source ecosystem. Implement the steps today, automate with one of the free tools, and you’ll never be caught off‑guard by a hidden license again.
