Check the workflow, not just the product name.

← Back to claims & evidence

Honua supports selected Esri-client workflows through its GeoServices REST surface, but compatibility is operation-scoped. Record the client version, operation, parameters, authentication flow, and extensions you depend on, then check each requirement against the public matrix. For Honua SDK packages, see SDK availability & compatibility.

Compatibility has a stated scope. “Compatible” here means the named operation or workflow is covered by public source, documentation, and test evidence. It does not mean 100% ArcGIS parity, and Honua is not certified, sponsored, or endorsed by Esri.

GeoServices REST coverage

The public GeoServices parity matrix ↗ is the current source for operation and parameter details. This summary omits operation counts so it does not become a second, stale matrix.

Desktop-client boundary

The public client compatibility and limitations page ↗ is the source for ArcGIS Pro, ArcPy, QGIS, and other client workflows. A migration assessment should capture the client's version, connection type, operations exercised, authentication flow, and any extension-specific behavior rather than relying on a product-name checkbox.

OGC and STAC evidence

Open-standard conformance is tracked separately from Esri compatibility. The dated public snapshot reports 952/952 applicable/basic/core CITE assertions across 11 suites; this is Honua's own test evidence, not formal OGC certification.

Evaluate your estate in four steps

  1. Inventory the exact service types, operations, parameters, authentication flows, and clients in use.
  2. Map each requirement to the public parity and client-limitations documentation.
  3. Run the workload against the exact Honua revision or pilot build under evaluation, using representative data.
  4. Record supported, workaround, and gap outcomes before cutover.

Use the migration playbook to start independently, or discuss your migration scope with Honua.
