SigNoz is an OpenTelemetry-native observability platform that combines logs, metrics, and traces with APM, dashboards, and alerts in one tool.
Open time-series database for metrics, events, and IoT telemetry
InfluxDB is an open time-series database for metrics, events, and IoT telemetry, queried with SQL and InfluxQL and run self-managed or as a managed cloud.
Open-source Python workflow orchestration for resilient data pipelines
Prefect is an open-source workflow orchestration framework that turns Python functions into resilient data pipelines with scheduling, retries, and event triggers.
High-performance observability pipeline for logs and metrics
Vector is a Rust observability data pipeline that collects, transforms, and routes logs and metrics from dozens of sources to any vendor sink.
Open-source observability for logs, metrics, traces and RUM in one binary
OpenObserve is an open-source observability platform that unifies logs, metrics, traces, RUM and AI model telemetry in one Rust binary backed by object storage.
Fast, cost-effective open-source time-series database and monitoring
VictoriaMetrics is an open-source time-series database and monitoring solution that ingests Prometheus, InfluxDB, OpenTelemetry and Graphite data and queries it with PromQL-compatible MetricsQL.
Open-source API gateway for routing, security, and AI traffic
Apache APISIX is a self-hosted, open-source API gateway that routes traffic to upstream services with authentication, rate limiting, and observability.
Open-source data pipeline that ingests, transforms, and ships logs and events
Logstash is a free open-source data collection engine from Elastic that ingests, transforms, and ships logs and events through real-time pipelines.
Apache 2.0 search and analytics suite with AI-ready retrieval
OpenSearch is an Apache 2.0 search and analytics suite for ingesting, searching, visualizing, and analyzing data at scale, with vector search for AI applications.
Open-source AI gateway routing 200+ providers with fallbacks
Portkey AI Gateway is an open-source gateway that routes app traffic across 200+ LLM providers with fallbacks, load balancing, caching, and guardrails.
Open-source AIOps for alert correlation, deduplication, and automated remediation
Keep is an open-source AIOps platform that aggregates alerts from 90+ providers, deduplicates them with AI, and automates remediation via YAML or visual workflows.
Cloud-native search engine for logs on object storage
Quickwit is an open-source, cloud-native search engine built for log management and analytics directly on object storage, written in Rust on top of Tantivy.
Open-source observability unifying logs, traces, metrics, and session replay
HyperDX is an open-source observability platform unifying session replays, logs, traces, metrics, and errors for faster production debugging.
Open-source fullstack monitoring with replay, errors, logs, and traces
Highlight is an open-source fullstack monitoring platform with session replay, error monitoring, logging, and tracing, plus a Docker self-hosting path.
Self-hosted LLM gateway with one OpenAI-compatible API
Bifrost is a self-hosted gateway that puts every large language model call behind one OpenAI-compatible API. An application points its existing OpenAI client at the gateway, and Bifrost routes the request to whichever provider is configured, so switching models or spreading load across providers is a configuration change rather than a rewrite.
Zero-instrumentation observability with eBPF and AI root-cause analysis
Coroot watches a whole system without asking developers to change their code.
Open-source uptime monitoring, incident response, and status pages in one platform
OneUptime is an open-source monitoring and incident platform with uptime checks, on-call alerting, status pages, and correlated logs, metrics, and traces, self-hosted or as a managed cloud.
Open-source observability database for metrics, logs, and traces
GreptimeDB is an open-source observability database that stores metrics, logs, and traces in one columnar engine backed by object storage.
Self-hosted monitoring for networks, servers, and cloud
Zabbix is a self-hosted monitoring platform that tracks networks, servers, virtual machines, and cloud services from one distributed setup, with agents and agentless checks feeding dashboards, alerting, and escalation under a free AGPL license.
Open-source APM with traces, metrics, and logs in one UI
Uptrace is a self-hosted APM that collects OpenTelemetry traces, metrics, and logs into one UI with dashboards, alerting, and PromQL-style queries.
Stateless open-source API gateway for aggregation and traffic control
KrakenD is a stateless, open-source API gateway written in Go that merges multiple backend calls into single endpoints with authentication, rate limiting, and observability.
Agent-based infrastructure and application monitoring for hybrid IT
Checkmk is a self-hosted monitoring platform for servers, networks, containers, and cloud services, with automatic discovery and alerting built in.
Open-source streaming SQL engine for real-time analytics
Timeplus Proton is an open-source streaming SQL engine in a single C++ binary that turns Kafka and log streams into real-time analytics with millisecond latency.
Open-source infrastructure monitoring with distributed checks and alerting
Icinga is open-source infrastructure monitoring for servers, networks, and services, with distributed checks, alerts, and self-hosting under a GPL licence.
Error tracking that speaks the Sentry protocol
GlitchTip accepts events from the official Sentry SDKs, which means adopting it is a DSN change rather than an instrumentation project. Stack traces, breadcrumbs, releases, and issue grouping all work as expected.
Self-hosted error tracking that works with Sentry SDKs
Bugsink is a self-hosted error tracker that collects exceptions from running apps and shows them in one place with stack traces and context.
Self-hosted observability backend for logs, metrics, and traces
Gigapipe is a self-hosted observability backend that stores logs, metrics, traces, and profiles in ClickHouse and serves Loki, Prometheus, Tempo, and Pyroscope APIs.
Open-source GraphQL federation platform and API gateway
WunderGraph Cosmo is an open-source platform for GraphQL federation that composes REST and GraphQL services into one unified gateway API.
Self-hosted alert intelligence with AI root-cause analysis for on-call teams
Wachd is a self-hosted alert intelligence platform that takes webhooks from Grafana, Datadog, and Prometheus, gathers context, strips PII, correlates events into a causal timeline, and sends a plain-English diagnosis to the on-call engineer.
Infrastructure monitoring, logs, and tracing in one platform
Datadog's value is correlation. A latency spike on a dashboard, the traces behind it, and the logs from the affected hosts are one or two clicks apart, which is the difference between a ten minute incident and an hour.
Application performance monitoring with usage based pricing
New Relic was the application performance monitoring product for a generation of web applications, and its repricing to per-user plus per-gigabyte was an explicit attempt to answer the complaint about host based billing.
Error tracking and performance monitoring for applications
Sentry is the tool most teams install first and remove last. An unhandled exception arrives with a stack trace, the release that introduced it, the users affected, and the breadcrumbs leading up to it.
