Use Case

Onboard Developers in Days, Not Weeks

Every week a new developer spends ramping up costs you $3,000-5,000 in salary and lost velocity. Dockr generates the documentation they need to become productive - before they write their first commit.

The Real Cost

What slow onboarding actually costs you

Avg. onboarding time

3-4 weeks ↓ 2-3 days

Senior dev hours lost to mentoring

8-12 hrs/week ↓ 1-2 hrs/week

Time to first meaningful commit

10-15 days ↓ 1-2 days

We hired a senior backend engineer who spent 3 weeks reading code before touching a feature. With Dockr, our next hire was shipping pull requests on day 3.

How It Works

Four steps to instant codebase context

Connect the repo

Link your GitHub or GitLab repository. Dockr scans the entire codebase and maps dependencies, entry points, and architecture in under 2 minutes.

Generate the map

Dockr produces interactive class diagrams, sequence flows, and a high-level system overview. New developers see how pieces fit together before reading a single line of code.

Explain every file

Each file gets a natural-language summary: what it does, why it exists, and how it connects to other modules. No more hunting through comments or commit messages.

Stay current forever

A webhook keeps docs in sync with every push. When the codebase evolves, the onboarding map evolves with it - automatically.

The Difference

Week 1 with vs. without Dockr

Without Dockr

Mon

Clone repo, read README, realize it's 2 years old

Tue

Ask senior dev #1 to explain auth flow. Wait 4 hours.

Wed

Trace API calls manually through 12 files. Get lost.

Thu-Fri

Repeat for billing module. Book more senior dev time.

Week 2-3

Still building mental model. First PR: typo fix.

With Dockr

Mon AM

Read auto-generated architecture overview (5 min)

Mon PM

Browse class diagram, understand data flow

Tue

Dive into file explanations for auth module

Wed

Check sequence diagram for API request lifecycle

Thu-Fri

First meaningful PR: feature implementation

Bonus

Ask questions in plain English

New developer asks

"How does the auth module work?"

"Which service handles billing?"

"What breaks if I change this function?"

Dockr answers instantly

The auth module uses JWT tokens with a 15-minute expiry. Here's the sequence diagram and the files involved...

Billing is handled by src/services/billing.ts. It depends on the user and payment modules...

This function is called by 4 other modules. Changing the return type would affect the API layer and 2 frontend components...

Natural language questions + auto-generated documentation = new developers get answers without interrupting senior engineers.

Questions about onboarding with Dockr

How quickly can a new developer get productive with Dockr?

Most developers can navigate the codebase and make their first meaningful contribution within 2-3 days of using Dockr-generated docs, compared to 3-4 weeks without documentation.

Does Dockr work for monorepos and microservices?

Yes. Dockr analyzes repository structure and generates both high-level architecture maps and per-service documentation. Monorepos get inter-module dependency graphs.

What if our codebase has poor existing documentation?

That's exactly the problem Dockr solves. It reads the code itself - not existing docs - so it works equally well on greenfield and legacy projects.

Can onboarding docs be shared with contractors or freelancers?

Yes. Generated documentation is accessible via shareable links. Contractors get the same context as full-time team members without needing repository access beyond what you grant.
