For Developer Onboarding
Onboard new developers in days, not months

New engineers spend weeks figuring out how the system works. Archyl provides an interactive architecture map that new hires can explore, query with AI, and understand at their own pace -- cutting onboarding time dramatically.

The problems you know, solved one by one

Every one of these compounds over time. Here is what changes when the architecture lives in Archyl.

Today

Onboarding takes months, not days

New developers spend 3-6 months before they feel productive. Most of that time is spent understanding the system, not writing code.

With Archyl

Interactive C4 map to explore the system

New hires start at the System Context level and zoom in progressively. Click on any system, container, or component to learn what it does and how it connects.

Today

Architecture knowledge is tribal

The only way to learn the system is to ask senior engineers, who are busy shipping features. Knowledge transfer is ad-hoc and incomplete.

With Archyl

AI answers architecture questions instantly

New developers ask Claude, Cursor, or Windsurf about the architecture through the MCP server. 'What does the payment service depend on?' -- instant, accurate answers.

Today

Documentation is outdated or missing

The wiki has architecture diagrams from two years ago. Half the services have changed, some are gone, and new ones are not documented at all.

With Archyl

Living documentation that stays current

Drift detection ensures the architecture map reflects the actual codebase. New hires trust the docs because they are provably up to date.

Today

New hires are afraid to ask questions

Asking 'how does this work?' for the tenth time feels awkward. New engineers suffer in silence and make mistakes from misunderstanding.

With Archyl

ADRs explain the why behind decisions

New engineers do not just see what exists -- they understand why it was built this way. ADRs linked to C4 elements provide context that seniors would otherwise have to repeat.

What you get

Built for the way you work

Overlays for Context

Show team ownership, deployment environments, or technology stacks as visual overlays. New hires learn who owns what and where things run.

Flows Show User Journeys

Documented user and system flows show how requests move through the architecture. New engineers understand end-to-end behavior, not just individual services.

Architecture as Code Is Familiar

Developers can read the archyl.yaml DSL file in the repository to understand the architecture using tools they already know -- their code editor.

9-Language Platform Support

International teams can onboard in their native language. Full platform localization in English, French, Spanish, German, Chinese, Japanese, Portuguese, Korean, and Italian.

Technology Radar Overview

New hires immediately see which technologies the organization uses, which are being adopted, and which are being phased out.

AI Discovery Keeps the Map Fresh

The architecture map updates automatically as the codebase evolves. New hires always see the current state, not a historical snapshot.

A day with Archyl

How it fits into your week

No new ritual to adopt. Archyl shows up where the work already happens.
