Unified observability. Triage Faster.·last9.io

Last9 is an observability platform built for high-cardinality telemetry, providing a developer-first control plane to manage logs, metrics, and traces. It supports OpenTelemetry, Prometheus, and over 100 integrations, offering real-time alerting, data pipelines, real user monitoring, and AI-native features like an MCP server. The platform helps engineering teams debug, optimize, and scale systems while controlling telemetry costs.

Pricing

Pro plan is $3250/month for up to 25 billion events, with additional pay-as-you-go usage pricing beyond that quota. Enterprise pricing is custom/quote-based. The site also states 'Start observing for free. No lock-in.' but no distinct free plan is listed among the two priced offers in the structured pricing data.

Pro$3250/mo

Described as pay-as-you-go usage pricing for production apps with growing scale.

25 billion events/month included; 90-day retention for metrics; 14-day retention for logs and traces

EnterpriseQuote

Quote-based custom pricing for large apps at internet scale.
