Where each one falls short

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

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

ShotSpotter

  • ShotSpotter now trades as SoundThinking and shotspotter.com redirects to soundthinking.com
  • No pricing is published; the site routes to contact and demo requests with no published rate, minimum or cost driver
  • The service depends on an acoustic sensor array installed across a defined coverage area rather than being software alone
