Onboard Project Overview

Try Onboard on a real codebase

Explore a live demo using the 163k LOC Apache codebase.

This demo runs entirely on a single ~$3,000 workstation. All analysis and AI processing happen entirely on-device - nothing is sent to the cloud.

Launch Live Demo

No setup required - runs in your browser

Onboard works best on your laptop or monitor

Replace Outdated Docs with Reality

Onboard turns your codebase into a shared, reliable source of truth. Instead of relying on outdated docs or digging through files, every developer can explore the system as it existed at a specific point in time—read-only, consistent, and fully connected. No manual cross-referencing required.

Onboard is your documentation.

AI guidance that stays grounded

Like an always-available Senior Engineer, Onboard AI is ready to answer your questions

Onboard combines large language models with the deep code relationship data generated by SciTools Understand. By providing the AI with accurate cross-reference information about how code elements interact, Onboard delivers precise explanations of files, functions, classes, and architecture—resulting in far more reliable insights than AI tools that rely on source text alone.

  • Ask about any file, function, or module
  • Get explanations tied to real code relationships
  • Understand logic, flow, and dependencies instantly
  • No cloud required—your code stays on your machine

Get newbies the big picture

Onboard gives your team a reliable view of how your codebase actually works.

Powered by the deep cross-reference and static analysis of SciTools Understand, it lets developers explore how files, functions, and modules connect—so everyone can navigate the system with a consistent understanding.

  • Interactive call trees and called-by trees to understand impact and dependencies
  • Commit-anchored baselines that provide stable, reproducible snapshots of the codebase
  • Shareable baseline links and exports for onboarding, reviews, and release discussions
