Last9 Overview
Last9 is a reliability-focused observability platform built around service ownership and SLO tracking. It brings metrics, logs, and traces into a unified view but emphasizes reliability signals over raw telemetry depth. The platform is designed for engineering teams that want to move from incident-driven firefighting to proactive reliability management.
Last9’s core strength is its SLO-first interface. Instead of starting with dashboards or raw metrics, you define what “working” means for each service using service level objectives. The platform then surfaces budget burn rates, error budget depletion, and risk scores that help teams prioritize what to fix before customers notice. This approach works especially well for teams with multiple services where each service has a clear owner and defined uptime expectations.
Last9 supports OpenTelemetry natively, making it straightforward to send traces, metrics, and logs using OTel collectors. It also integrates with Prometheus, Grafana, and common CI/CD pipelines. The platform includes basic alerting, log search, and distributed tracing but does not offer synthetic monitoring, session replay, or advanced error tracking comparable to full-stack APM platforms.
Pricing is usage based but not publicly detailed on their website. Teams typically start with a custom quote after a demo. According to user feedback on SourceForge, Last9’s pricing tends to be simpler than platforms with multiple billing dimensions, though exact figures require direct engagement with their sales team.
Last9 runs as SaaS only. There is no self-hosted or BYOC deployment option, which rules it out for teams with strict data residency or compliance requirements.
Coralogix Overview
Coralogix is a log analytics and observability platform with real time in-stream processing at its core. Instead of ingesting all logs and indexing everything, Coralogix analyzes data in-stream before it hits storage. This approach allows teams to run analytics, detect patterns, and trigger alerts on high-volume log streams without paying to store every log line. The platform calls this model “Streama,” and it reduces storage costs significantly for log-heavy workloads.
Coralogix supports full MELT observability: metrics, events, logs, and traces. It integrates with OpenTelemetry, Prometheus, Fluentd, and Logstash. The platform includes APM capabilities, error tracking, Kubernetes monitoring, and RUM (real user monitoring). It also offers AI-powered log clustering and anomaly detection, which helps surface outliers in noisy log streams.
Coralogix’s pricing is structured around data volume with different rates depending on how data is processed. According to their public pricing page, logs cost $0.42/GB when processed via Streama, and full indexing costs more. Metrics and traces follow separate pricing models. The total monthly cost for a mid-market team ingesting 30TB of logs per month typically ranges from $12,600 to $15,000, depending on indexing choices and retention settings.
Like Last9, Coralogix is SaaS only. There is no on-premises or hybrid deployment option. Teams with data residency requirements or regulatory constraints cannot keep telemetry data inside their own infrastructure when using Coralogix. Users on Reddit’s r/kubernetes thread note that Coralogix’s pricing is simpler than Datadog’s multi-dimensional billing but still requires careful estimation as log volume scales.
Feature-by-Feature Comparison
Pricing and Cost Transparency
Last9 does not publish detailed pricing publicly. Teams receive custom quotes based on usage volume and feature requirements. The pricing model is usage based, but the exact per-GB rates or host charges are not available on their website. This lack of transparency makes it difficult to estimate costs before engaging with their sales team.
Coralogix publishes its pricing model on its website. Logs cost $0.42/GB when processed via Streama, which filters and analyzes data in-stream before storage. Full indexing costs more, and metrics and traces follow separate pricing tiers. For a mid-market team ingesting 30TB of logs per month, the estimated cost is approximately $12,600 per month, excluding metrics and traces. This estimate assumes 100% Streama processing with no full indexing. Adding full indexing or higher retention periods increases costs significantly.
CubeAPM uses a flat $0.15/GB pricing model for all ingested telemetry: logs, traces, metrics, and events. There are no per-host fees, no per-user seats, and no separate indexing charges. Unlimited retention is included at no extra cost. For a mid-market team ingesting 30TB per month, CubeAPM costs $4,500 per month. CubeAPM runs inside your own infrastructure, so there are no public cloud egress fees when sending telemetry data to a SaaS provider.
Pricing based on publicly available information as of April 2026. Enterprise discounts, custom contracts, and negotiated rates are not reflected here.
OpenTelemetry Support
Both Last9 and Coralogix support OpenTelemetry natively. You can send traces, metrics, and logs using the OTel Collector without installing proprietary agents. Both platforms also support Prometheus, Fluentd, and Logstash for teams with existing telemetry pipelines.
CubeAPM is OTel native from the ground up. It also supports Prometheus, Elastic, Datadog, and New Relic agents, allowing incremental migration without ripping out existing instrumentation.
SLO and Reliability Features
Last9 is built around SLOs. You define error budgets, burn rates, and availability targets for each service. The platform surfaces which services are at risk, how much budget remains, and when to prioritize reliability work over feature development. This approach works well for teams practicing service ownership where each service has a clear owner and uptime expectation.
Coralogix includes basic SLO tracking but does not emphasize reliability workflows as strongly as Last9. Its core strength is log analytics and real time pattern detection, not service-level reliability management.
CubeAPM includes full SLO tracking with burn rate alerts, error budget dashboards, and service-level latency and availability monitoring. It also correlates SLO violations with traces, logs, and infrastructure metrics to accelerate root cause analysis.
Deployment Options
Last9 is SaaS only. There is no self-hosted or BYOC option. All telemetry data is sent to Last9’s cloud infrastructure.
Coralogix is also SaaS only. Teams with data residency requirements, HIPAA compliance, or strict regulatory constraints cannot keep telemetry data inside their own infrastructure when using Coralogix.
CubeAPM runs inside your own cloud VPC or on-premises data center. All telemetry data stays within your infrastructure. This deployment model eliminates cloud egress fees, supports data residency compliance, and keeps monitoring functional even during internet outages.
Log Management and Search
Last9 includes basic log search and aggregation. It is not designed as a log-first platform, so teams with high log volumes or complex log analytics workflows may find it limited compared to dedicated log platforms.
Coralogix is log-first. Its in-stream processing model analyzes logs in real time before storage, which reduces costs for high-volume log ingestion. The platform includes AI-powered log clustering, anomaly detection, and pattern recognition that help surface outliers in noisy streams. Log search is fast and supports full-text queries across indexed logs.
CubeAPM includes full-text log search with unlimited retention. All logs are indexed automatically, and search performance remains fast even at TB scale. Logs are automatically correlated with traces and metrics, making it easy to drill from an error log to the exact trace and service that caused it.
APM and Distributed Tracing
Last9 includes distributed tracing but does not emphasize deep APM workflows. Tracing is available as part of the broader observability stack, but the platform’s core strength is reliability management, not detailed trace analysis.
Coralogix includes full APM with distributed tracing, service maps, and latency breakdowns. Traces are automatically correlated with logs and metrics. The platform also includes error tracking and basic RUM.
CubeAPM provides full-fidelity distributed tracing with no sampling at ingest. Every trace is stored and searchable. Service maps, span-level latency breakdowns, and trace-to-log correlation are included. CubeAPM also tracks RED metrics (rate, errors, duration) at service and endpoint level.
Alerting
Last9 includes SLO-based alerting with burn rate thresholds. You can alert when error budgets deplete faster than expected. Basic metric and log alerts are also supported.
Coralogix includes flexible alerting across logs, metrics, and traces. The platform includes AI-assisted anomaly detection that reduces false positives. Alerts can route to Slack, PagerDuty, email, and webhooks.
CubeAPM includes full alerting across all signal types with anomaly detection, noise suppression, and context-rich notifications. Alerts include links to the relevant trace, log, or metric that triggered the alert, reducing time to root cause.
Kubernetes and Infrastructure Monitoring
