The short version

  • Each has a real cost: Linkerd deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits; Logto advanced features like RBAC, organizations, MFA, and enterprise SSO are billed as separate paid add-ons rather than included in Pro.
  • They diverge on capability: Linkerd covers Automatic mutual TLS, Logto covers Prebuilt sign-in UI.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Linkerd

  • Deliberately fewer features than Istio, so complex routing and multi-cluster policy can hit its limits
  • Kubernetes only, with no story for workloads outside a cluster
  • A sidecar per pod is still real memory and latency overhead, however small, and a mesh is another layer to debug during incidents

Logto

  • Advanced features like RBAC, organizations, MFA, and enterprise SSO are billed as separate paid add-ons rather than included in Pro.
  • Enterprise pricing is not published and requires contacting sales.
  • Token-based billing can make cost forecasting harder than flat per-MAU pricing for high-traffic apps.

Answered from the vendors’ own pages

Linkerd: Is Linkerd free?

The open-source project is free. Buoyant, its maintainer, sells enterprise distributions and support separately.

Logto: What does Logto cost?

Logto offers a Free plan at $0/month, a Pro plan starting at $24/month with 50K free tokens included, and a custom-priced Enterprise plan. Extra add-ons like RBAC or MFA are billed separately on Pro.

Linkerd: Linkerd or Istio?

Linkerd trades features for simplicity, with a smaller proxy and far less configuration. Istio is more capable and correspondingly more work to run.

Logto: Is there a free plan, and what are its limits?

Yes. The Free plan supports up to 50,000 monthly active users, 3 total applications, 1 machine-to-machine app, 3 social connectors, 1 webhook, and 3-day audit log retention.

Source
Linkerd: Do I need a service mesh at all?

Only if you need mutual TLS, uniform retries or per-service traffic metrics across many services. For a handful of services it is usually more machinery than the problem justifies.

Logto: How is usage metered?

Logto uses token-based billing: only access tokens issued for authentication and authorization activity are counted, rather than charging purely per MAU.
