12 Free Engineering Intelligence Tools Every CTO Should Bookmark

TLDR: 12 free tools that extract real engineering intelligence from GitHub data. No sign-up, no credit card. Paste a URL, get answers. Explore all tools → intelig.ai/tools

I got tired of watching CTOs make decisions based on Jira dashboards and gut feelings.

So we built 12 free tools that extract real engineering intelligence from GitHub data. Every one of them works the same way: paste a GitHub org URL, get data. No account required.

Here’s the full list.

1. Org Scanner

The flagship. Paste any GitHub org and get a full engineering intelligence report — health score (0-100), key findings with severity ratings, top contributors, repository health table, PR analysis, and weekly velocity chart. This is the tool that shows everything at once.

2. Executive Summary

The board-ready version. Same data as the scanner but the AI narrative is structured for executives — health score, key risks, velocity trends, and strategic recommendations. Drop this into your next board deck.

3. Engineering Cost Estimator

Enter a GitHub org and an average salary figure. Get cost per commit, cost per active contributor, and industry benchmarks. We scanned Vercel — $1,910 per commit. Your CFO tracks cost per customer. You should track cost per commit.

4. Bus Factor Calculator

Find out how many people would need to leave before critical knowledge is lost. The AI classifies contributors into risk tiers — Immediate Concern, Elevated Risk, and Notable Risk — with specific mitigation recommendations.

5. AI Code Attribution Scanner

Measure how much of your codebase is AI-assisted. Detects bot contributors, analyzes commit timing patterns, and estimates AI-assisted code percentage. We scanned Vercel — MODERATE signal level, 22-31% estimated AI-assisted code.

6. PR Cycle Time Benchmark

How long do PRs take from open to merge? Compare your cycle times against DORA performance categories — Elite, High, Medium, or Low. Vercel scored ELITE with a 0.0 day median cycle time.

7. Velocity Tracker

Track commit velocity over time across your entire org. See weekly trends, surge/trough patterns, and momentum indicators. Real output measured in commits, not story points.

Try it →

8. Repo Health Check

Deep health assessment for individual repositories. Commit recency, contributor count, maintenance signals, and risk indicators. Point it at a specific repo — not just an org.

Try it →

9. Repo Sprawl Auditor

Find your dead repos. Naming duplicate clusters, abandoned repositories, and archival candidates — with AI-generated cleanup priorities. We found 2 naming clusters in Vercel’s org with specific archive/merge/rename recommendations.

10. Release Cadence Analyzer

How often does your org actually ship? Measure release frequency and map it to DORA deployment frequency categories. Consistent cadence correlates with engineering maturity.

Try it →

11. Contributor Spotlight

Deep-dive into a single contributor’s cross-repo impact. Specialist vs generalist classification, knowledge concentration analysis, and organizational dependency assessment.

Try it →

12. Org Comparison

Head-to-head comparison of two GitHub organizations. Health scores, velocity, bus factor, contributor distribution. Benchmark against competitors or aspirational peers.

Why we built these free

Two reasons.

First, every CTO should have access to basic engineering intelligence. You shouldn’t need a $50K platform to answer “what’s my bus factor?” or “how fast are we shipping?” These are table-stakes questions.

Second, once you see what’s possible with surface-level GitHub data, you’ll want to see what’s possible with deep analysis across your entire engineering operation. That’s what the full InteliG platform does — but the free tools stand on their own.

No sign-up. No sales call. No “freemium” bait-and-switch. Just data.
