ArcSync — Architecture Diagrams from Infrastructure-as-Code
ArcSync turns your IaC repository into a synced, interactive architecture diagram. Point it at a Git repo containing Terraform .tf, CloudFormation YAML/JSON, or AWS CDK source (TypeScript, JavaScript, Python, Go, Java, C#) and get a live, editable diagram back. Re-parses on every push, with drift detection on every pull request.
The interactive editor requires JavaScript. For agents and other clients, the documentation is available as Markdown at llms.txt, llms-full.txt, and agents.md; machine-readable rate limits and endpoint policy at agent-permissions.json.
API quick example
Start an async parse from a public GitHub repo:
curl -X POST https://api.arcsync.dev/graphs/generate \
-H "Authorization: Bearer $ARCSYNC_TOKEN" \
-H "Content-Type: application/json" \
-d '{"repoUrl":"https://github.com/your-org/your-repo"}'
Poll /graphs/{id}/status until the graph is ready, then fetch /graphs/{id}.
