Poesis
If you want a curated, architect-owned application portfolio with mature reporting and a large ecosystem, the established EA category is a safe choice.
LeanIX Alternative — IT Governance Platform
Evaluate an established EA offering against your requirements and the bounded Poesis roadmap. ITIP inventory, sourcing, appraisal and simulation are planned; inspectable foundations are not an operated replacement.
Credit where due
What the enterprise architecture management category does well.
The EA-repository category — of which LeanIX is a leading example — excels at giving architects a curated inventory, portfolio reports, and a shared vocabulary for application landscapes. If your need is an architect-maintained catalog with strong reporting, the category serves it well.
Where the approaches differ
Description versus definition.
Poesis explores explicit typed intent and evidence-linked definitions. The comparison dimensions below are evaluation questions, not verified limitations of any current vendor edition.
| Dimension | EA repository approach | Poesis for IT |
|---|---|---|
| Source of truth | Inventory recorded and maintained by architects (surveys, imports, curation) | Planned direct authoring or reviewed repository sourcing; code and configuration are not deployed observations |
| Drift | Verify discovery, freshness and reconciliation coverage for the selected edition and integrations | Planned correspondence checks need deployment identity, freshness, observation coverage and unknown-state handling |
| Obligations | Standards and policies referenced as documents alongside the model | Selected vocabulary exists; binding and complete supplied-instance Norm verdicts remain planned |
| Impact of change | Read from diagrams and dependency views | Planned bounded impact analysis; reachability is not causal simulation |
| AI-readiness | Verify current APIs, context interfaces and authorization contracts | Typed definition foundations; authorized read-only context and copilot integration remain planned |
Evaluation fit
When to choose which.
Consider a bounded pilot when explicit intent, provenance and typed context are the hypothesis to test, with capacity to integrate planned workflows and measure results.
An EA repository could be a curated input. A connector, identity mapping, authorization and review contract would need implementation; no live integration is asserted.
