Alternatives / BetterStack
Looking for an open source BetterStack alternative? We compared 18 open source uptime monitors, status pages, error trackers, and observability platforms by license, self-hosting, and features. Most are uptime or status page tools, and some are error tracking or APM, with several using source-available or open-core licenses.

We looked for open-source tools that overlap with BetterStack's core: uptime monitoring, status pages, incident alerts, and log or error visibility. We verified each project's license, recent activity, stars, and self-hosting in its repository. BetterStack is an all-in-one hosted product, so the list mixes uptime monitors, status pages, error trackers, and full observability stacks, and we flag source-available, open-core, and inactive projects. See our methodology for the full criteria.
If you host your monitoring on the same infrastructure as the sites you monitor, an outage can take both down. Run the monitor on separate infrastructure. Uptime Kuma and several others also lack built-in probing from multiple global locations, which BetterStack provides.
Uptime Kuma, Gatus, Checkmate, Peekaping, Kener, and EasyMonitor are uptime monitors with status pages. Cachet, OpenStatus, and Statusnook focus on status pages, Sentry and Highlight track errors, and HyperDX, Uptrace, and OneUptime are broader observability platforms. Healthchecks watches cron jobs with heartbeat pings, and Keep centralizes alerts.
Sentry uses the Functional Source License (FSL-1.1-Apache-2.0), and Cachet uses its own license that forbids distributing it as a standalone product. StatusScout uses a source-available license that restricts reselling it as a hosted service. Keep, OneUptime, and Highlight keep enterprise code in separate directories, and Checkmate uses AGPL-3.0 with a modified Section 7.
Uptime Kuma, HyperDX, Kener, Peekaping, EasyMonitor, and Statusnook are MIT. Gatus and Tianji are Apache-2.0, Healthchecks is BSD-3-Clause, and OpenStatus and Uptrace are AGPL-3.0.
Most projects had commits within days of this update. Peekaping's last commit was in May 2026, and Statusnook has had no commits since October 2024, so it is inactive.
BetterStack is a proprietary hosted service priced by monitors, team members, and data volume, with monitoring and incident data stored on its platform. Open-source alternatives let you self-host monitoring, avoid per-monitor and per-seat pricing, and keep logs and uptime data on your own infrastructure, at the cost of running the monitoring system yourself and losing built-in multi-region probes in some tools.
Uptime Kuma is an MIT-licensed, self-hosted monitoring tool for websites, ports, and services, with notifications through many channels and public status pages. It has no built-in distributed probing from multiple global locations, so checks run from where you host it.
Pricing: Free and open source.
Sentry is a developer-focused error tracking and performance monitoring platform with release management, available self-hosted. Its source is under the Functional Source License (FSL-1.1-Apache-2.0), which is source available and converts to Apache 2.0 after two years, so it is not standard open source.
Pricing: Free to self-host under the FSL terms; the hosted service has a free tier and paid plans.
Cachet is a long-running self-hosted status page system for communicating system status and incidents, with components, metrics, and subscribers, built on Laravel. It uses the Cachet License, which allows commercial use and modification but forbids distributing the software as a standalone product, so it is source available. Its latest tagged release is 2.4.1 from November 2023, and version 3 is in development.
Pricing: Free to self-host.
Keep is an open-source AIOps and alert management platform that centralizes alerts from monitoring tools, correlates and summarizes them with AI, and automates responses with workflows, with integrations for tools such as CloudWatch, Datadog, and Grafana. The repository is MIT except for the ee directory, which is under a separate license, and it offers enterprise authentication such as SSO, SAML, OIDC, and LDAP.
Pricing: Free to self-host; Keep Cloud and enterprise features are paid.
Gatus is an Apache-2.0 monitoring tool where checks are defined in a configuration file, with automated status pages and many alert channels, written in Go. It is configuration-driven rather than a point-and-click dashboard.
Pricing: Free and open source.
Checkmate is a self-hosted monitoring tool for websites, servers, and Docker containers with uptime checks, infrastructure metrics, and incident handling. It is AGPL-3.0 with a modified Section 7, with enterprise features that are paid.
Pricing: Free to self-host; enterprise features are paid.
Healthchecks is a BSD-3-Clause service that monitors cron jobs and scheduled tasks using heartbeat pings, alerting you when an expected ping does not arrive. It can be self-hosted, and the hosted service has a free tier with up to 20 checks.
Pricing: Free to self-host; the hosted service has a free tier and paid plans.
HyperDX is an MIT-licensed observability platform that combines logs, traces, metrics, errors, and session replays in one interface, built on ClickHouse and OpenTelemetry, with a hosted option billed by data volume.
Pricing: Free to self-host; the hosted service is usage-based.
Highlight is an open-source monitoring platform for error tracking, session replay, and performance monitoring for web apps, with an enterprise self-hosted option under a separate license. The repository is Apache-2.0 with portions under a separate enterprise license.
Pricing: Free to self-host the open-source parts; enterprise self-hosting and cloud are paid.
OpenStatus is an open-source status page, incident response, and uptime monitoring platform that checks endpoints from 28 global regions, with monitors and status pages declared in YAML or Terraform and an MCP interface. It is AGPL-3.0 and can be self-hosted, and a managed service is offered with a free plan limited to one monitor and one status page.
Pricing: Free to self-host; the managed service has a free plan and paid plans.
OneUptime is an open-source monitoring and observability platform that covers uptime monitoring, incident management, on-call, status pages, logs, and traces in one product that can be self-hosted. The Community Edition is Apache-2.0, while an ee directory holds Enterprise code, and a managed OneUptime Cloud is available.
Pricing: Free to self-host the Community Edition; cloud and Enterprise plans are paid.
Kener is an MIT-licensed status page system and uptime monitor that you deploy with Docker, supporting 11 service types, with a focus on status pages.
Pricing: Free and open source.
Uptrace is an AGPL-3.0 open-source APM built on OpenTelemetry for traces, metrics, and logs, with self-hosting that is free and a managed cloud priced by ingested data.
Pricing: Free to self-host; the managed cloud is priced by data ingested.
Tianji is an Apache-2.0 self-hosted bundle of website analytics, uptime monitoring, and status pages, designed to be lightweight, so it is not as deep as enterprise tools.
Pricing: Free and open source.
Peekaping is an MIT-licensed uptime monitoring tool for websites, databases, and services, with status pages. Its last commit was in May 2026, so development is slower than Uptime Kuma's.
Pricing: Free and open source.
Statusnook is an MIT-licensed status page system for incidents, maintenance, and user communication, with endpoint monitoring. Its last commit was in October 2024, so it appears inactive.
Pricing: Free and open source.
EasyMonitor is an MIT-licensed, self-hosted HTTP and ICMP monitoring tool with status pages that you can run with one Docker Compose command. Multi-region probes require your own infrastructure or VPN setup. It is a very small project.
Pricing: Free and open source.
StatusScout monitors security headers, SSL certificates, DNS records, exposed files, uptime, broken links, and user flows, and alerts you when something fails. It is self-hosted and free to run under the StatusScout License 2.0, which is source available with restrictions on reselling it as a hosted service. A managed cloud starts at $12 a month.
Pricing: Free to self-host; the managed cloud is paid.
