Before and after

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

Architecture evolves faster than documentation

Your SaaS ships daily. New services, database changes, and API integrations happen constantly. Documentation is outdated the moment it is written.

With Archyl

AI discovers your SaaS architecture

Connect your repositories and get a C4 model automatically. AI identifies microservices, databases, queues, external APIs, and how they connect.

Today

Microservices complexity grows silently

What started as a monolith is now 50+ microservices. Nobody has a complete picture of how they connect, what each one does, or who owns what.

With Archyl

Drift detection keeps docs current

Get a real-time health score showing how accurately your documentation reflects the actual codebase. Set CI/CD thresholds to prevent drift.

Today

Scaling teams need a shared understanding

Going from 10 to 100 engineers means architecture knowledge cannot live in a few people's heads. Every new team needs context to build correctly.

With Archyl

Architecture as Code in your workflow

Declare your C4 model in archyl.yaml and version it alongside your code. Documentation deploys with your application through CI/CD.

Today

Multi-tenant architecture is hard to communicate

Explaining how tenant isolation, data partitioning, and shared infrastructure work requires clear architecture documentation that traditional tools cannot provide.

With Archyl

C4 model scales with your architecture

Start with the big picture and zoom into any service. Four levels of detail serve everyone from the CEO to the junior developer.

What you get

Built for the way you work

MCP Server for AI Development

Engineers query architecture from Claude, Cursor, or Windsurf. 'What depends on the auth service?' 'Show the data pipeline architecture.'

Ownership & Team Overlays

Layer team ownership on your architecture diagram. Every service has a clear owner, reducing confusion in incidents and planning.

Conformance Rules for Standards

Define architecture standards and check compliance automatically. Ensure all teams follow shared conventions as the organization grows.

DORA Metrics Integration

Correlate architecture health with delivery performance. Understand how architecture decisions impact deployment speed and reliability.

Architecture Change Requests

Propose and review architecture changes through pull-request-style workflows. Lightweight governance for fast-moving SaaS teams.

Technology Radar

Track technology adoption across your SaaS stack. Know which technologies are growing, which need migration, and where to standardize.
