Where each one falls short

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

Bugsnag

  • Owned by SmartBear rather than being independent
  • The free tier covers 7,500 events a month
  • Paid tiers are usage-priced by event volume rather than by seat, so a noisy release raises the bill
  • Enterprise pricing is quote-only

ELK Stack

  • The free Basic self managed subscription excludes machine learning, alerting, single sign on via SAML or OpenID Connect, LDAP and Active Directory authentication, field and document level security, searchable snapshots and cross cluster replication
  • Cross cluster operations require the same subscription tier on every cluster involved
  • The 99.95 percent monthly uptime SLA applies only to the Platinum and Enterprise subscription tiers
  • Three deployment models are priced on three different bases: resource based for Cloud Hosted, usage based for Serverless and licence based on nodes and RAM for self managed
  • Elastic Cloud Serverless does not yet support traffic filtering, cross project search or bring your own key
  • The pricing page publishes no rate for any tier
