Incus vs Redocly: at a glance
What is Incus?
Incus 7.4 turns a year of migration plumbing into near-live migration that actually moves disks.
7.0.0 LTS became the supported baseline in May with 7.0.1 as its first patch, while the feature branch kept a roughly monthly cadence: 7.1 cleaned up issues the LTS surfaced, 7.2 added migration-compatible hypervisor flags for stateful migration, 7.3 shipped native Windows and macOS installers. 7.4 is the largest of them and the first with a headline capability — near-live migration implemented on both client and server, extended to dependent disks inside a cluster, with incremental memory migration made opt-in. Alongside it sit Secure Boot key management, a substantial NVRAM rework, librbd for all Ceph interactions, and disk and NIC burst limits.
What is Redocly?
Redocly ships MCP servers across its entire doc portal stack, making any hosted API docs directly queryable by AI agents.
The September 15 coordinated 0.137.0 release across Reef, Realm, Redoc, and the async API plugin was the centrepiece: every Redocly-hosted portal now ships with a /mcp endpoint, tabbed setup instructions for Claude and ChatGPT/Codex, an optional /mcp-public path for RBAC-restricted content, OAuth discovery per RFC 8414, and audience-validated bearer tokens. The MCP code mode was hardened to reduce agent script failures and produce cleaner error messages. Reunite (the CI/PR platform layer) is simultaneously shipping at higher frequency — multiple intra-day releases — with PR diff summaries and feedback origin filtering now live.

Incus

Incus 7.4 turns a year of migration plumbing into near-live migration that actually moves disks.
◆ Current state
7.0.0 LTS became the supported baseline in May with 7.0.1 as its first patch, while the feature branch kept a roughly monthly cadence: 7.1 cleaned up issues the LTS surfaced, 7.2 added migration-compatible hypervisor flags for stateful migration, 7.3 shipped native Windows and macOS installers. 7.4 is the largest of them and the first with a headline capability — near-live migration implemented on both client and server, extended to dependent disks inside a cluster, with incremental memory migration made opt-in. Alongside it sit Secure Boot key management, a substantial NVRAM rework, librbd for all Ceph interactions, and disk and NIC burst limits.
◆ Where it's heading
Migration has been the through-line for three releases and 7.4 is where it becomes a feature rather than plumbing. The pattern is consistent: 7.2 made stateful migration survive non-identical hosts, 7.4 makes moving an instance cheap enough to do routinely, including the storage that hangs off it. Around that, the VM side is maturing toward parity with commercial hypervisors — firmware key management, NVRAM control, per-device rate limits — which is the surface that decides whether Incus is usable as a datacentre hypervisor rather than a container manager that also runs VMs.
◆ Prediction
Expect the next release to harden near-live migration rather than replace it — the evacuation and cluster-recovery fixes already threaded through 7.4 suggest the gaps are in cluster-wide orchestration, not the transfer itself.
Redocly
7.5INFRA · APIS
Redocly ships MCP servers across its entire doc portal stack, making any hosted API docs directly queryable by AI agents.
◆ Current state
The September 15 coordinated 0.137.0 release across Reef, Realm, Redoc, and the async API plugin was the centrepiece: every Redocly-hosted portal now ships with a /mcp endpoint, tabbed setup instructions for Claude and ChatGPT/Codex, an optional /mcp-public path for RBAC-restricted content, OAuth discovery per RFC 8414, and audience-validated bearer tokens. The MCP code mode was hardened to reduce agent script failures and produce cleaner error messages. Reunite (the CI/PR platform layer) is simultaneously shipping at higher frequency — multiple intra-day releases — with PR diff summaries and feedback origin filtering now live.
◆ Where it's heading
Redocly is repositioning its doc portals from human-readable API references to AI-addressable knowledge bases. The depth of the MCP implementation (public/private endpoint split, OAuth, credential validation, code mode, feedback filtering by MCP source) indicates this is a strategic capability, not an experiment. Reunite's fast cadence suggests the CI layer is being tightened to support AI-driven review and deploy workflows.
◆ Prediction
The next likely additions to the MCP surface: agent write tools (create/update docs programmatically) and analytics on which endpoints agents query most. Reunite will close the loop by letting MCP-sourced feedback trigger doc update PRs.
