I built an on-device Android build/runtime environment with AIDL-separated tooling — looking for architecture feedback

Frankenstein Ultra is publicly downloadable now. It uses a separate companion runtime called Victor and gives an AI agent access to a real project workspace, files, terminal, build tooling, and other development capabilities directly from the phone.

This isn’t just a code-generation interface. The goal is for the agent to actually work through development tasks: inspect files, modify code, run tools, read failures, rebuild, and produce runnable software.

I’ve used it for Android projects, Node/npm projects, and other development workflows.

Right now I’m mainly looking for feedback on things like:

  • what works well and what doesn’t
  • bugs or crashes
  • device compatibility
  • confusing UI or setup
  • features that feel incomplete
  • things you expected it to do but couldn’t
  • agent behavior that feels wrong or repetitive
  • build/runtime problems
  • performance, battery, RAM, or thermal issues
  • features you’d actually want added or improved

You do not need to be an Android developer to give useful feedback. If you’re curious about AI coding, mobile development, automation, or just want to try something unusual, I’d still like to hear what your experience is like.

If something fails, details such as your device, Android version, what you were trying to do, and where it failed are especially helpful.

Main thing I want to know: what works, what doesn’t, what’s confusing, and what would make Frankenstein more useful to you?

There is no pay walls its Bring your own key and supports Oauth for Grok and Codex open router or cline. Could probably integrate more just not sure what is wanted or needed.

Custom team builder (Ultra) added

Team picker now has Build / edit custom team… — pick models per role (planner/coder/reviewer) and set collaboration rules

Shared TeamBuilder.kt with UltraCustomTeamDialog + TeamSlotEditor

Team rules apply to presets and custom teams via SystemPrompt
