The short version

  • Only Avo has a free tier, so it costs nothing to try first.
  • 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.; BigID pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.
  • They diverge on capability: Avo covers Tracking plan, BigID covers Structured and unstructured scanning.
  • Prices and features above were last checked on 31 August 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.

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.

BigID

  • Pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.
  • Scanning large unstructured estates is slow and computationally expensive, so most organisations sample rather than scan everything, which reintroduces uncertainty into the very question they bought the tool to settle.
  • Classification accuracy on messy unstructured content requires tuning, and out of the box false positives on things like reference numbers create a large triage backlog that a small governance team cannot clear.
  • It discovers and reports but does not remediate, so realising value requires a separate process and often separate tooling to actually delete, restrict or move the data it flags.
  • It is built for large enterprises and both the price and the administrative overhead are disproportionate below a few thousand employees, where a lighter DSPM tool covers the security use case for far less.

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.

BigID: What does BigID cost?

It is quoted by data source count and volume. Reported contracts run from roughly 15,000 to 175,000 US dollars a year, and add-on modules such as AI security posture are licensed on top.

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.

BigID: Does it handle unstructured data?

Yes, and that is its main advantage. It classifies data in files and shares and correlates findings back to individuals, not just to data types.

Avo: Does Avo replace Amplitude or Mixpanel?

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

BigID: Will it delete the data it finds?

Not by itself in most deployments. It identifies and routes findings; deletion and remediation happen through your own processes or connected systems.

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.

BigID: Is it a privacy tool or a security tool?

Both are sold from the same discovery core. Buyers increasingly come from security wanting data security posture management rather than from legal wanting privacy.
