Open-source Honeycomb MCP alternatives
Honeycomb's MCP server is open source, so you can read which query, dataset, Board, Trigger, and SLO calls an agent can make before connecting it to production telemetry. Every server below publishes its source too.
Auditing the repo matters here, where the agent runs queries against live event data and can manage alerts. Open source lets you confirm the exact API surface, pin a version, and patch behaviour rather than waiting on a vendor to ship a fix.
The 8 best open-source alternatives
Grafana Labs' server is open source, matching Grafana's roots: search and edit dashboards, query Prometheus and Loki, and reach incidents, alerts, and OnCall, all auditable in source.
Set up Grafana →Sentry's open-source server is focused on errors: pull issues, stack traces, and events, and run Seer root-cause analysis, with code you can read before granting access to production exceptions.
Set up Sentry →The open-source Prometheus server talks straight to your instance: PromQL instant and range queries, metric and metadata discovery, and scrape-target inspection, fully inspectable.
Set up Prometheus →SigNoz is open source end to end, and its server reaches traces, logs, metrics, dashboards, and alerts in an OpenTelemetry-native stack you can host and audit yourself.
Set up SigNoz →PagerDuty's open-source server exposes incidents, services, schedules, teams, and orchestrations across 64 tools, read-only by default, with a repo you can read end to end.
Set up PagerDuty →- DatadogOfficial
Datadog publishes its server source even though the platform is hosted: search logs, query metrics, pull APM traces, inspect monitors, and investigate incidents, with code to audit first.
Set up Datadog → - New RelicOfficial
New Relic's server is open source and hosted: run NRQL, search entities, analyze golden metrics, and triage incidents, with source you can read despite the managed backend.
Set up New Relic → For CloudWatch and related signals, the open-source AWS Labs server runs any AWS CLI command with validation and a read-only mode, reaching AWS observability from a repo you control.
Set up AWS (AWS Labs) →
How to choose
Among the open-source options, Prometheus and SigNoz let you run and audit the backend itself rather than only the client. Grafana, Sentry, Datadog, and New Relic publish their servers while keeping the platform or backend hosted. PagerDuty covers on-call, the AWS server reaches CloudWatch. Read the repo before letting an agent query or manage alerts against production.
FAQ
- Is the Honeycomb MCP server open source?
- Yes. Honeycomb publishes the server's source, so you can audit which query, dataset, Board, Trigger, and SLO calls an agent can make. Every alternative on this page ships its code publicly too, even where the platform behind it is hosted.
- Which open-source alternative can I run entirely on my own stack?
- Prometheus and SigNoz. Both publish their code and run on infrastructure you control, so the telemetry backend and the server are yours. Honeycomb itself is hosted-only, and Grafana, Sentry, Datadog, and New Relic open-source the server while keeping the backend hosted.
