A senior tech lead,
inside your Unity Editor.
One click scans your project, pinpoints performance bottlenecks and version-migration blockers, and gives you fixes you can actually apply — the safe ones in one click.
Deterministic diagnosis. AI only where it helps.
Detection runs on a rule engine — reproducible, offline, zero tokens. The LLM is only used to explain a finding in plain language, answer follow-ups, and generate fix snippets. Stable results, controllable cost.
🎯 Deterministic engine
Roslyn script analysis + asset/import/project-settings scanners. Same project, same findings, every time. No cloud round-trip to get a report.
🛠️ Safe one-click fixes
Import-setting fixes apply in a batch with a preview and full Undo. You stay in control — nothing changes your project silently.
🤖 AI Fix with a safety net
Script-level fixes are compile-verified after writing; if the build breaks, the change is rolled back automatically. Only the snippet you choose is ever sent.
Three diagnostic domains
Every finding has a severity, an exact location, the impact, and a fix.
Find what actually costs frames
- Uncompressed / oversized textures, redundant Read/Write, Sprite mipmaps
- Per-frame GC: GetComponent / Camera.main / FindObjectOfType in Update, string concat, LINQ, WaitForSeconds
- Debug.Log left in builds, batching-breaking materials, SRP instancing hints
- Mesh & audio import settings that bloat memory
Trim the dead weight
- Duplicate assets (content-hashed groups) with one-click select + CSV export
- Unreferenced assets pulled into the build
- Conservative, low-false-positive — report-class items are never auto-deleted
Survive the Unity 6 upgrade
- Deprecated / removed APIs, located to the exact line, with replacements
- Old vs new Input System mixing, package-version vs your Unity compatibility
- manifest.json preview / legacy package checks
- One-click AI migration for safe renames (compile-verified, auto-rollback on failure)
From install to fixed in minutes
Free where it matters. Pay to save time.

Questions
Does it upload my project or source code?
No. All scanning and analysis happen locally in your editor. The only thing ever sent is, when you explicitly use Explain or AI Fix, the finding's metadata or the single code snippet you chose. By default that goes through PerfLint's proxy, which never logs request bodies, to deepseek — or, if you add your own provider key, direct to the provider, never through our servers.
Do I need an API key?
No. AI Fix and Explain work out of the box — zero config — using your plan's AI credits through our proxy. If you'd rather use your own key (Claude or DeepSeek), add it under Advanced: those calls go direct to the provider, are unlimited, and never count against credits. The deterministic scan, findings, and health report need no key and no network at all.
Monthly or annual?
Pro is a subscription: pay $9.99/mo billed monthly, or $95.88/year billed annually ($7.99/mo — save 20%). Both unlock the same features and the same monthly AI credit allowance.
Which Unity versions are supported?
Unity 2021.3 and newer, including Unity 6. Migration rules are version-aware — you won't get noise about APIs that aren't actually deprecated in your version.
Will AI Fix break my code?
AI Fix writes the change, triggers a compile, and automatically rolls back if compilation fails. It's scoped to safe, mechanical changes (e.g. API renames). We still recommend committing to version control first.
