The short version

  • Each has a real cost: Icinga the free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased; Tilt docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.
  • They diverge on capability: Icinga covers Forever Free core, Tilt covers Live update.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Where each one falls short

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

Icinga

  • The free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased
  • Repository access for enterprise Linux distributions like RHEL and SLES is not free, so organisations standardised on those distributions face a real recurring cost most open source monitoring buyers do not expect
  • Enterprise modules are gated behind a separate module subscription, so some functionality demonstrated in marketing material is not part of the free core
  • Self-hosting and operating Icinga requires real Linux and monitoring expertise that a commercial SaaS tool would otherwise absorb, so total cost of ownership includes staff time not captured in the licence price
  • Pricing for the paid subscriptions varies by geographic region and is not published as a single global rate card, complicating budgeting for multinational organisations
  • The web interface and configuration language, while capable, are less immediately polished than a fully commercial tool like PRTG, and initial setup takes longer to reach a usable state

Tilt

  • Docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.
  • The Tiltfile is Starlark, a Python dialect, so non-trivial setups become real programs that need reviewing and maintaining, and the person who wrote yours becomes a single point of failure.
  • Live update only works when the running container can accept synced files and restart the process; compiled languages, distroless images and read-only filesystems often force you back to a full image rebuild, which removes the main benefit.
  • It assumes Kubernetes. If your development target is plain Docker Compose or serverless functions, Tilt adds a cluster you did not need and a layer of abstraction with no payoff.
  • There is no commercial support contract, no SLA and no paid tier, so when a Kubernetes version upgrade breaks something you are dependent on GitHub issues and a Slack channel rather than a vendor you can escalate to.

Answered from the vendors’ own pages

Icinga: Is Icinga free to run in production?

Yes, the core platform has no licence fee and no limit on hosts or services monitored.

Tilt: Is Tilt free?

Yes, entirely. It is Apache 2.0 open source with no paid tier and no licence fee.

Icinga: What do the paid subscriptions actually add?

A repository subscription provides packages for certain enterprise Linux distributions, a module subscription unlocks enterprise-only add-on modules, and a support subscription bundles both with professional support.

Tilt: Who owns Tilt now?

Docker, which acquired it in May 2022. It remains open source and the repository is still actively maintained.

Icinga: Is Icinga related to Nagios?

Yes, it originated as a fork of Nagios but has since diverged into an independently developed platform.

Tilt: Do I need a remote cluster?

No. It works against a local cluster such as kind, minikube or Docker Desktop, and also against a shared remote development cluster if your services are too heavy to run locally.

Tilt: How is it different from Skaffold?

Both automate the build-deploy loop. Tilt puts more weight on the live-update path and a multi-service dashboard; Skaffold is more configuration-driven and closer to Google's tooling.
