The short version

  • Only Namespace has a free tier, so it costs nothing to try first.
  • Each has a real cost: Namespace developer plan is pay-as-you-go only; minimum usage unclear; Sysdig custom pricing requires sales contact, difficult to compare costs
  • They diverge on capability: Namespace covers Devboxes, Sysdig covers Real-time threat detection and response.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Namespace

  • Developer plan is pay-as-you-go only; minimum usage unclear
  • Team plan $100/mo is competitive but usage limits may be tight
  • Devbox pricing separate at $0.004/minute could add up quickly
  • Enterprise plan requires custom sales conversation

Sysdig

  • Custom pricing requires sales contact, difficult to compare costs
  • No published pricing tiers or calculator available
  • Primarily focused on cloud-native environments
  • Requires integration with existing SIEM or monitoring tools for full visibility
  • Steep learning curve for runtime security concepts

Answered from the vendors’ own pages

Namespace: How is compute usage metered on the Developer plan?

Developer plan uses pay-as-you-go billing. Devboxes bill at $0.004 per minute. Storage and caching services have separate usage-based fees. A 30-day free trial is available to test usage patterns.

Source
Sysdig: How does Sysdig achieve real-time threat detection?

Sysdig uses runtime intelligence with kernel-level system visibility, capturing live system calls to detect threats at machine speed, typically within 2 seconds.

Source
Namespace: What is the difference between Team and Business plans?

Team ($100/mo) includes 100,000 unit minutes and 1,000 Docker builds with email support. Business ($250/mo) includes 250,000 unit minutes, 2,500 Docker builds, and high concurrency with a dedicated Slack channel.

Source
Sysdig: What is runtime intelligence and how does it differ from configuration-based security?

Runtime intelligence reveals what is actually executing in cloud environments through kernel-level visibility, rather than relying on theoretical risks from configuration analysis alone.

Source
Namespace: Can Namespace support AI coding agents?

Yes, Namespace Devboxes are specifically designed as feature-rich development environments for AI coding agents, with full tooling and performance optimization.

Source
Sysdig: What cloud platforms does Sysdig support?

Sysdig supports AWS, GCP, Azure, and IBM Cloud with multiple regional data centers across US, EU, and other regions.

Source
Sysdig: Does Sysdig integrate with existing security tools?
