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

PlanetScale

  • Pricing varies significantly across 17+ AWS and GCP regions
  • Additional costs for EBS storage beyond base tier, backup storage, and egress
  • Dedicated PgBouncer and replicas incur separate charges
  • Metal tier pricing increases sharply with larger configurations

Questions people ask

Is Avo or PlanetScale better?
Neither clearly leads. Avo starts at Free and PlanetScale at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Avo or PlanetScale?
Avo starts at Free and PlanetScale at Free.
Does Avo or PlanetScale run on more platforms?
Avo runs on Web, iOS, Android, API. PlanetScale runs on Web.
Can I use Avo for free?
Both have a free tier, so you can try either at no cost before committing.
What is Avo best used for?
Avo is most often used for a product team whose ios and android event names have drifted apart, making cross-platform funnels meaningless, an analytics lead who wants tracking changes to go through review rather than appearing in production unannounced, a company migrating between analytics tools that needs a canonical event schema independent of any vendor, an engineering organisation that wants event tracking mistakes caught by the compiler rather than by an analyst three months later. Of those, a product team whose ios and android event names have drifted apart, making cross-platform funnels meaningless and an analytics lead who wants tracking changes to go through review rather than appearing in production unannounced are not what PlanetScale is typically brought in for.
What can Avo do that PlanetScale cannot?
Avo covers Tracking plan, Code generation, Inspector, Branching and approvals. PlanetScale covers Database Branching, Non-blocking Schema Changes, Insights, Horizontal Scaling.

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.

PlanetScale: How much does a PlanetScale Postgres database cost per month?

PlanetScale Postgres pricing starts at $5/month for single-node ARM64 configurations with 512 MiB RAM and $15/month for the same specs in high-availability mode with 1 primary and 2 replicas. Metal tier starts at $50/month for M-10 configuration (1/8 vCPU, 1 GiB RAM). Exact pricing depends on cluster size, node architecture (ARM64 vs x86-64), storage configuration, and selected AWS/GCP region.

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.

PlanetScale: Is there a free tier for PlanetScale?

PlanetScale offers a free tier for development and testing workloads. After free tier limits are reached, usage-based pricing applies starting at $5/month for the smallest Postgres single-node configuration, with costs scaling based on cluster size, compute, storage, and additional features like dedicated PgBouncer or replicas.

Source
Avo: Does Avo replace Amplitude or Mixpanel?

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

PlanetScale: What is the difference between PlanetScale ARM64 and x86-64 pricing?

ARM64 instances cost significantly less than x86-64 equivalents. For example, a Postgres EBS HA cluster with 512 MiB RAM costs $15/month on ARM64 but $39/month on x86-64. This pricing difference extends across all cluster sizes, with larger x86-64 configurations reaching up to $5,599/month compared to ARM64 alternatives.

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.

PlanetScale: What is included in a PlanetScale cluster price versus additional costs?

The advertised cluster price covers the base compute and configured storage. Additional charges apply for EBS storage beyond the base allocation, backup storage, data egress, optional dedicated PgBouncer connections, and replicas beyond the base high-availability configuration. Regional pricing varies across 17+ AWS and GCP zones.
