The short version

  • Each has a real cost: Avo editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.; Nagios XI free Edition caps at 7 nodes or 100 services, whichever limit is hit first

Where each one falls short

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

Avo

  • Editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.
  • Avo governs event definitions but does not fix historic data, so an organisation with years of inconsistent tracking still faces the backfill problem it cannot solve.
  • Code generation requires engineering teams to adopt generated modules in their build, and in practice some platform teams resist, leaving parts of the estate ungoverned and the plan only partly enforced.
  • Inspector event volume is capped by tier, at 100,000 on free and one million on enterprise, so a high-traffic consumer product samples rather than observes everything and drift can hide in the unobserved portion.
  • It is an additional tool in an analytics stack that already costs money, and justifying it requires the organisation to accept that its existing data is unreliable, which is a political argument as much as a budgetary one.

Nagios XI

  • Free Edition caps at 7 nodes or 100 services, whichever limit is hit first
  • Standard Edition is licensed per node count, starting at $2,595 for 100 nodes and rising to $14,995 for 1,000 nodes
  • Enterprise Edition, which adds capacity planning and SLA reporting, is sold as an add-on starting at $4,690 for 100 nodes on top of the base license
  • Sitewide Edition for large distributed environments has no published price and requires contacting sales

Avo: What exactly does code generation give me?

Type-safe tracking functions per platform, so a wrong event name or property type fails at compile time rather than in production data.

Nagios XI: Is there a free version of Nagios XI?

Yes, Nagios XI Free Edition is available at no cost with a limit of 7 nodes or 100 services, whichever is reached first.

Source
Avo: Does Avo replace Amplitude or Mixpanel?

No. It governs the events those tools receive; you still need an analytics product.

Nagios XI: What is included with Nagios XI licensing?

Initial licenses include one year of free version upgrades, up to 10 support cases, and support portal access. Each license permits three installations: production, backup/failover, and testing/development.

Source

250 US dollars a month billed annually for five editors, or 300 billed monthly, with extra editors at 50 dollars.
