The short version

  • Only Axiom has a free tier, so it costs nothing to try first.
  • Each has a real cost: Axiom no self-hosted or air-gapped deployment option for compliance-sensitive workloads; PlanetScale eBS High Availability requires 3-node configuration with replication overhead
  • They diverge on capability: Axiom covers Serverless architecture, PlanetScale covers Database Branching.

Where each one falls short

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

Axiom

  • No self-hosted or air-gapped deployment option for compliance-sensitive workloads
  • Vendor lock-in due to APL (Axiom Processing Language) not transferring to other platforms
  • Proprietary storage format limits data portability and external analytics access
  • Complex pricing model with multiple cost dimensions (ingestion, compute, storage) makes budgeting difficult at scale
  • Limited ecosystem integration; does not integrate deeply with existing observability stacks like Grafana for metrics and Jaeger for traces

PlanetScale

  • EBS High Availability requires 3-node configuration with replication overhead
  • EBS Non-HA single-node option lacks redundancy and automatic failover
  • Pricing varies by cloud provider and region, requiring queries for specific rates
  • ARM64 architecture only available on EBS tier, not Metal deployments

Answered from the vendors’ own pages

Axiom: Does Axiom offer a free tier with no time limit?

Yes, Axiom's Personal plan is permanently free and includes 500GB of data ingest per month, 10 GB-hours of query compute, and 25GB storage with 30-day retention. No credit card is required.

Source
Axiom: Can I self-host Axiom or use my own cloud infrastructure?

No, Axiom is cloud-only. There is no self-hosted option, air-gapped deployment, or Bring Your Own Cloud available. The platform is a fully managed service.

Source
Axiom: What is Axiom's query language and does it work with SQL?

Axiom uses APL (Axiom Processing Language), based on Kusto Query Language. It is not standard SQL, and APL skills and queries do not transfer to other platforms, creating vendor lock-in.

Source
Axiom: What integrations does Axiom support for alerting?

Axiom supports pre-built integrations with Slack and PagerDuty, plus custom webhooks. Alerts can be configured via threshold-based, anomaly detection, or match-based monitors.

Source
Axiom: How does Axiom's pricing scale with data volume?

Axiom uses consumption-based pricing with automatic volume discounts. Costs depend on data loading volume, query compute usage (measured in GB-hours), and storage. The Team plan starts at $25/month with included allowances, then overage charges apply per unit with volume-based discounts.

Source
Axiom: What platforms can access Axiom's web interface?

Axiom's web app supports Chrome, Edge, Firefox, and Safari. Mobile access is supported on iOS and Android, but some features like moving dashboard elements are unavailable on mobile.
