Microcks vs OctoPrint: at a glance
What is Microcks?
Microcks is quietly wiring LLM example generation into an API mocking tool built for Kubernetes.
Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.
What is OctoPrint?
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.

Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.
◆ Where it's heading
Two threads run in parallel. The deployment story keeps getting tightened for Kubernetes — OCI-packaged Helm charts, native-image reflection registration, an Uber distribution — which is where a mock server has to live to be useful in CI. The more interesting thread is example generation: authoring realistic mock data is the actual work of using a mocking tool, and Microcks is putting a model behind it rather than asking users to write it. That work is still surfacing as commit lines rather than headline features.
◆ Prediction
The 1.15 line should reach a final release given the pre-release pattern, and the LLM example generation is the thread most likely to move from plumbing to a named capability if it keeps expanding.
OctoPrint
5.0INFRA · APIS
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
◆ Current state
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
◆ Where it's heading
The 2.0 line is in a long stabilisation, with each candidate fixing regressions and asking testers to cover the new connectors. The thin notes on rc6 and rc7 suggest the remaining changes are small.
◆ Prediction
A 2.0.0 final is likely within a few candidates; the exact date is unclear from the entries.
