Documentation

Install, scan, fix. No account required to scan — Pro features unlock with a license.

Requirements

  • Unity 2021.3 or newer (including Unity 6).
  • Works on Windows and macOS editors.
  • No network needed for the scan. Explain / AI Fix work out of the box — zero config, no API key required.

Install (UPM, Git URL)

In Unity: Window ▸ Package Manager ▸ + ▸ Add package from git URL… and paste:

https://github.com/your-org/perflint-unity.git?path=/packages/com.perflint.unity

Or add it to Packages/manifest.json directly:

{
  "dependencies": {
    "com.perflint.unity": "https://github.com/your-org/perflint-unity.git?path=/packages/com.perflint.unity"
  }
}
Prefer a pinned version? Append #v0.9.2 (or any tag) to the Git URL.

Run your first scan

  1. Open Tools ▸ PerfLint ▸ Scan Project (shortcut Ctrl/Cmd + Shift + L).
  2. Click Scan Project. A report appears in seconds.
  3. Findings are grouped Performance / Assets / Migration / ProjectSettings, each with a severity, location, impact, and fix.
  4. Use the filters (Critical / Warning / Info, “only fixable”, search) to focus. Export anything to CSV.

Applying fixes (Pro)

  • One-click / batch fixes for deterministic, low-risk issues (import settings, etc.). A preview is shown and the change is undoable via Edit ▸ Undo.
  • AI Fix for script-level issues: only the flagged snippet is sent to your LLM provider. The result is compile-verified after writing and auto-rolled-back if the build breaks.
We recommend committing to version control before applying batch or AI fixes.

AI Fix & Explain (zero-config)

Explain and AI Fix work out of the box — no API key, no setup. Calls run through PerfLint's zero-log proxy to the hosted model, metered by your plan's AI credits (Free: 10/day; Pro: a large monthly pool).

Prefer your own provider? Open the LLM button in the PerfLint toolbar → Advanced: bring your own API key:

  • Pick a provider — Claude (Anthropic) or DeepSeek — and paste your key.
  • Your key is stored in local EditorPrefs only, calls go direct to the provider (never through our servers), and are unlimited — never counted against credits.
  • Routine explanations use a cheap/fast model; migration-domain rules auto-use a stronger model.

Activating Pro

  1. Buy a license — Get Pro ($9.99/mo, or $95.88/yr — save 20%). You'll receive a license key.
  2. In Unity, open the Free / Pro button in the PerfLint toolbar → License window.
  3. Paste your key and click Activate. The status flips to Pro and the fix / Explain / AI Fix actions unlock.

Activation works offline for a grace period and re-checks periodically. Deactivate on a machine to free the seat for another.

Privacy

The scan is 100% local — your code and art assets never leave your machine. The only outbound data is, when you explicitly trigger Explain or AI Fix, the finding metadata or the single snippet you selected. By default it goes through PerfLint's proxy — which never logs request bodies — to deepseek; if you add your own provider key under Advanced, it goes direct to the provider and never through our servers. License checks send only your license key.
