Licensing

Stellarion uses a simple two-tier model: Community (free, open source) and Pro (license key).

Community Edition

All 28 community tools are free to use. No license key needed. This includes:

• Code analysis (AI context, complexity, impact, call graphs, dependencies)
• Search and navigation (symbol search, callers/callees, imports, signatures)
• Persistent memory (7 tools for cross-session knowledge)
• Indexing (workspace, files, directories)

Pro Edition

16 additional tools for architects and team leads. Requires a license key.

Included in Pro:

• Codebase health dashboard
• Tech debt reports
• Change risk assessment
• Coupling analysis
• Dependency drift detection
• API surface reports
• Security scanning
• Dead code detection
• Code similarity (duplicates, clustering, comparison)
• Git history mining and semantic search

180-Day Free Trial

A free trial starts automatically when you first run Stellarion. All Pro tools are available for 180 days with no signup and no credit card.

Getting a License

Purchase a Pro license at stellarion.ai/pro.

Installing Your License Key

Save your license key to ~/.stellarion/license.key:

macOS / Linux:

mkdir -p ~/.stellarion
echo "YOUR_LICENSE_KEY" > ~/.stellarion/license.key

Windows (PowerShell):

New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.stellarion"
"YOUR_LICENSE_KEY" | Out-File -FilePath "$env:USERPROFILE\.stellarion\license.key" -Encoding UTF8

You can also set the license via environment variable:

export STELLARION_LICENSE=/path/to/license.key

VS Code Extension

In VS Code, use the command palette: Stellarion: Activate License and paste your key.

Verifying Your License

stellarion-server --info

Output shows your edition and license status:

stellarion-server v2.0.0
Author: Stellarion <info@stellarion.ai>
License: Proprietary
Edition: pro (Acme Corp, expires 2027-01-01)

How Pro Tools Work

All 44 tools are always visible — Pro tools are marked with Pro in their descriptions. When you invoke a Pro tool:

• With valid license: tool executes normally
• Trial active: tool executes normally (180-day window)
• No license / expired: tool returns a message with a link to purchase

Pro tools never disappear from the tool list. AI agents can discover them and understand what's available.

License Key Format

License keys are base64-encoded JSON payloads:

{
  "org": "Acme Corp",
  "email": "dev@acme.com",
  "seats": 10,
  "expires": "2027-01-01",
  "features": ["all"],
  "tier": "pro"
}

Licenses can grant specific feature sets or all features:

Offline-First

All license validation happens locally. No phone-home, no internet required. The license key contains all the information needed for validation.
