Architecture Documentation for Startups

Keep your startup's architecture visible as you scale. Free tier, AI auto-discovery from code, quick setup, and Architecture as Code for fast-moving teams.

Ship fast without losing track of your architecture

Growing startups accumulate tech debt silently. Archyl auto-discovers your architecture from code so you always know what you have built -- without slowing down to document it.

Tech debt from rapid growth

Moving fast is essential, but every shortcut accumulates invisible tech debt. Without visibility into your architecture, refactoring becomes a guessing game.

No time to write documentation

Your team is shipping features, not writing architecture docs. Traditional documentation tools require effort that startups simply cannot afford.

Team scaling breaks knowledge sharing

Going from 5 to 50 engineers means architecture knowledge can no longer live in people's heads. New hires need a map of the system.

Architecture decisions are invisible

Critical design decisions are made in Slack threads and lost. When someone asks why the system works this way, nobody remembers.

AI auto-discovers your architecture

Point Archyl at your repositories and get a C4 model in minutes, not days. AI identifies services, databases, APIs, and their relationships automatically.

Quick setup, zero ceremony

No week-long onboarding. Connect your Git repos, let AI discover, refine with the visual editor, and you have living documentation in under an hour.

Architecture as Code fits your workflow

Declare your architecture in archyl.yaml alongside your code. It deploys with your CI/CD pipeline -- documentation that is as fast as your team.

Free plan to get started

The Developer plan is free forever. Start documenting your architecture today and upgrade to Business or Scale plans as your team grows.

MCP Server for AI Agents

Let Claude, Cursor, or Windsurf query your architecture through 191 MCP tools. Your AI coding assistant knows your system structure.

Know instantly when your code diverges from your documented architecture. Catch tech debt before it becomes unmanageable.

Architecture Decision Records

Capture the why behind architecture choices. Future you and your growing team will thank present you.

C4 Model Visualization

See your system at four levels of detail: Context, Containers, Components, and Code. Zoom in and out as needed.

Visual Editor & Code DSL

Drag-and-drop or write YAML. Both approaches keep the same model in sync, so use whichever feels natural.

Change Request Workflows

Propose architecture changes with review flows -- lightweight governance that does not slow you down.
