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.; MongoDB Atlas m0 free tier limited to learning and exploration only with no backup capability

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.

MongoDB Atlas

  • M0 free tier limited to learning and exploration only with no backup capability
  • Data transfer egress charges apply at 0.12 USD/GB for dedicated clusters; inbound free
  • MongoDB Search and Vector Search add significant per-hour costs starting at 0.12 USD/hour

Answered from the vendors’ own pages

Avo: Is the free tier usable in production?

Yes. It includes two editors, code generation and 100,000 events observed in Inspector, which is enough for a small team.

MongoDB Atlas: How much does MongoDB Atlas cost?

MongoDB Atlas offers a free M0 tier with 512 MB storage, Flex tier at approximately 8-30 USD/month with pay-per-hour billing, shared clusters at 9-25 USD/month, and dedicated clusters from 56.94 USD/month. Add-on services like MongoDB Search cost 0.12-3.27 USD/hour.

Source
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.

MongoDB Atlas: Is there a free tier?

Yes, MongoDB Atlas M0 free tier offers 512 MB storage with shared resources, suitable for learning and exploration. Flex tier allows pay-as-you-go usage starting at 0.011 USD/hour.

Source
Avo: Does Avo replace Amplitude or Mixpanel?

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

MongoDB Atlas: What are the data transfer limits?

Inbound data transfer is typically free; egress from dedicated clusters costs 0.12 USD/GB. Free and Flex tiers do not incur data transfer charges.

Source
Avo: How much is the Team plan?

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

MongoDB Atlas: What backup options are available?

M0 free tier and Flex tier do not include backups. Dedicated clusters M10 and above include backup services with region and snapshot storage-based pricing.
