Stop paying per-GB for your own logs.

KalDB delivers the power of Splunk and Datadog without the astronomical per-GB pricing, unpredictable bills, and loss of data sovereignty.

The SaaS Log Analytics Problem

Why teams are abandoning per-GB pricing models

1. Unpredictable Costs

Per-GB ingestion pricing means bills spike with traffic. A successful product launch can bankrupt your observability budget.

2. Data Sampling & Dropping

To control costs, teams sample or drop logs. When incidents happen, the data you need is often missing.

3. Retention Limitations

Long-term retention is prohibitively expensive. Compliance requirements force painful tradeoffs.

4. Vendor Lock-in

Proprietary query languages and formats trap your data. Migration becomes a multi-quarter project.

5. Data Sovereignty Loss

Your logs leave your infrastructure. For regulated industries, this creates compliance nightmares.

6. Query Limitations

Complex queries time out or get throttled. Cardinality limits restrict what you can analyze.

7. Security Concerns

Sensitive log data leaves your network. Third-party breaches put your data at risk.

8. No BYOC Option

Can't run in your own cloud account. No way to meet strict data residency requirements.

9. Budget Politics

Engineering teams argue with finance over log budgets. Observability becomes a cost center, not an enabler.

Your Logs, Your Infrastructure

Why data sovereignty matters

With SaaS Providers
  • Logs leave your network to third-party servers
  • Subject to third-party data breaches
  • May violate GDPR, HIPAA, or SOC2 requirements
  • No control over data residency
  • Vendor can access your data
With KalDB
  • Logs stay in your AWS/GCP/Azure account
  • Your security controls, your encryption keys
  • Full compliance with data residency requirements
  • Choose your region, your VPC, your rules
  • Only you can access your data
