Ilograph vs Preceden

Ilograph creates interactive visual documentation for systems and the ways their components interact. Users can zoom between detailed and broad views, switch perspectives, and use sequence perspectives to show data, business and security flows. Its model-based diagrams-as-code approach adds structure and supports consistency and reuse. Diagrams can be navigated by keyboard and are designed for screen readers; environments include AWS, Azure, GCP and networking icons. Ilograph Desktop runs on Mac, Windows and Linux, and works with local files without internet access for offline or high-security environments. The Export API runs in an on-premises Docker container without external internet access and produces standalone HTML files. Its Confluence Cloud app stores diagrams in the Confluence instance and does not require an Ilograph account. The free plan includes unlimited public and private diagrams, unlimited diagram size and 14 days of history. Listed paid options include Pro at $18.00 per month billed yearly, Team at $30.00 per month billed monthly, and Desktop at $14.99 per month billed monthly.
