SLO Tracking & Error Budget Platforms

Purpose-built platforms that define targets, track SLIs against them, and manage the error budget as it burns.

SLO Tracker (open source)

Free, open-source tool originally built at Squadcast to track SLOs and error budgets — unified dashboard, false-positive reclaiming, and webhook integrations with Prometheus, Datadog, New Relic, and Grafana.

Squadcast SLO Tracker (SolarWinds)

Now part of SolarWinds Incident Response — unified service intelligence and SLO management with real-time error budget burn-rate tracking and service dependency mapping.

SLO Tracking

Nobl9

Reliability platform purpose-built for SLOs — composite SLOs, SLO backtesting, error-budget alerting, and SLO oversight to keep targets relevant as services evolve.

SLO Tracking

Incident-Integrated Reliability Platforms

Platforms that fold SLO and error-budget signal directly into incident response and observability data.

Blameless (now FireHydrant)

Blameless's incident collaboration and reliability-insight capabilities are now part of FireHydrant — resolve incidents in Slack, Teams, and Google Chat while automatically capturing reliability data.

Incident-Integrated

Last9

Unified, high-cardinality observability platform for metrics, logs, and traces — helps teams measure SLAs accurately and track customer impact proactively at massive scale.

Incident-Integrated

Open Standards & Observability-Native SLOs

A vendor-neutral SLO specification and a full-stack observability platform with error budget and burn-rate alerting built in.

OpenSLO

Open Service Level Objective specification designed for modern Git workflows — declarative, vendor-agnostic YAML definitions for reliability and performance targets, with an "oslo" validation CLI.

Open Standard

New Relic

Intelligent observability platform bringing telemetry, operational context, and AI together — includes error budget and burn-rate alerting alongside full-stack APM, infrastructure, and log data.
