Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Craft Docs

  • Primarily designed for Apple ecosystem; limited support for Windows or Android
  • Smaller ecosystem and community compared to Notion or Obsidian
  • Collaboration features less mature than dedicated team document platforms
  • Requires learning Craft-specific formatting and structure

Istio

  • Sidecar mode adds an Envoy container to every pod, which costs CPU and memory per workload and adds a hop of latency in each direction, and it introduces a startup ordering problem where an application container can begin making calls before its proxy is ready
  • Upgrades are projects rather than patches: you run revisioned control planes, canary the new revision and restart every workload to pick up new sidecars, and Istio supports only a narrow band of recent minor versions, so this recurs roughly quarterly for as long as you run it
  • The API surface is large, spanning VirtualService, DestinationRule, Gateway, PeerAuthentication, AuthorizationPolicy, Sidecar and the Kubernetes Gateway API, and a mistake usually appears as a 503 with an Envoy response flag rather than a rejected configuration, so debugging requires Envoy knowledge, not just Istio knowledge
  • Ambient mode removes the sidecar but is a different architecture with its own components and does not cover every feature the sidecar path does, so adopting it is a migration and a re-test of your policies rather than a configuration switch
  • It is Kubernetes-first; adding virtual machine workloads to the mesh is supported but much less well-trodden, so a mixed estate of Kubernetes and VMs ends up maintaining two networking and identity models
  • Below a few dozen services, most of what teams actually want (encrypted internal traffic, retries, weighted rollouts) is available from a cloud load balancer or from Linkerd with a fraction of the components, and at that scale Istio commonly becomes the single largest source of production incidents

Answered from the vendors’ own pages

Craft Docs: What platforms does Craft Docs support?

Craft Docs is available on iOS, iPad, and Mac, with deep integration into Apple's ecosystem. A web version is also available.

Source
Istio: Do we need a service mesh at all?

Only if you have enough services, or a compliance requirement, that implementing mTLS, retries and tracing per language has become unmanageable. Below roughly a few dozen services, an ingress controller plus good client libraries usually delivers more reliability for less operational cost.

Craft Docs: Can you collaborate on documents in Craft Docs?

Yes. Craft Docs supports real-time collaboration, allowing multiple users to edit documents simultaneously.

Source
Istio: Sidecar mode or ambient mode?

Ambient removes the per-pod proxy and its startup ordering problems and costs less at high pod counts, but it is a newer architecture and does not cover every sidecar feature. New deployments should evaluate ambient first; existing sidecar meshes should treat the move as a migration project.

Craft Docs: Does Craft Docs have AI features?

Yes. Craft Docs includes AI-powered writing assistance and editing features.

Source
Istio: How does it compare with Linkerd?

Linkerd is deliberately smaller, uses its own Rust proxy rather than Envoy, and is quicker to operate; Istio has a far larger feature surface, multi-cluster and VM support, and broader vendor backing. Note that Linkerd's stable distribution builds are commercially licensed by Buoyant, whereas Istio's releases are freely available.

Craft Docs: Can you use Craft Docs offline?

Yes. Craft Docs allows offline editing with synchronization when connectivity is restored.

Source
Istio: Who supports it commercially?

Solo.io and Tetrate sell supported distributions and control planes, and Google offers Cloud Service Mesh as a managed option. The upstream project itself is CNCF-governed with community support.

Istio: Does it work outside Kubernetes?

Partly. Virtual machine workloads can be added to a mesh, but the tooling, documentation and community experience are heavily Kubernetes-centred, so a VM-majority estate is fighting the grain of the project.
