Open-source Better Stack MCP alternatives
Better Stack's MCP server is closed and run by Better Stack: you connect over the network and cannot read or fork the code. If you would rather use a server whose source you can audit, every option below publishes its code. That matters when you need to vet what an agent can query in your telemetry, or patch behaviour yourself instead of waiting on the vendor.
These are the open-source observability servers people compare against Better Stack. Several run locally; a few also offer a hosted endpoint. They cover metrics, traces, logs, errors, and on-call in their own query dialects.
The 8 best open-source alternatives
Grafana Labs' official server is open source and queries dashboards, Prometheus, Loki, incidents, alerts, and OnCall. Read the repo before pointing it at your stack, and run it locally rather than over a hosted URL.
Set up Grafana →Sentry's official server is open source and pulls issues, stack traces, and events, plus Seer root-cause analysis. Adjacent to Better Stack on errors, with code you can inspect before granting access to your projects.
Set up Sentry →Fully open and built around PromQL, this community Prometheus server runs instant and range queries, discovers metrics and metadata, and inspects scrape targets. The direct, auditable fit for Prometheus metrics.
Set up Prometheus →OpenTelemetry-native and open source, SigNoz's official server exposes traces, logs, metrics, dashboards, and alerts. It covers the same signals as Better Stack and the source confirms its reach.
Set up SigNoz →Open source and read-only by default, the official PagerDuty server exposes incidents, services, schedules, teams, and orchestrations. It deepens the on-call side rather than general telemetry queries.
Set up PagerDuty →- DatadogOfficial
Datadog's official server is open source and searches logs, queries metrics, pulls APM traces, inspects monitors, and investigates incidents. A broad option you can audit, though you reach it as a hosted endpoint.
Set up Datadog → - HoneycombOfficial
Built for event-level, high-cardinality debugging, the official Honeycomb server is open source and queries traces, metrics, and logs, runs BubbleUp, and manages Boards, Triggers, and SLOs. Auditable before you connect it.
Set up Honeycomb → - New RelicOfficial
Open source and built around NRQL, the official New Relic server runs queries, searches entities, analyzes golden metrics, and triages incidents. Reading the repo shows exactly which NRQL the agent can issue against your account.

How to choose
Every option here is open source, so all of them can be audited before you connect them. For metrics you run yourself, Prometheus and Grafana are the most battle-tested; SigNoz adds traces and logs in an OpenTelemetry stack. Datadog, Honeycomb, and New Relic are open as well but reached as hosted endpoints. Sentry and PagerDuty deepen the error and on-call sides. Read the repo before wiring any of them into production telemetry.
FAQ
- Is the Better Stack MCP server open source?
- No. Better Stack runs the server itself and does not publish its source, so you connect over the network and cannot audit or modify it. Every alternative on this page ships its code publicly.
- Which open-source alternative can I run myself?
- Grafana, Prometheus, SigNoz, Sentry, and PagerDuty all install locally over stdio, so the server process and its credentials stay on your own infrastructure. Datadog, Honeycomb, and New Relic publish their code too but are reached as hosted endpoints rather than run yourself.
