Frequently Asked Questions
TraceKit has open-source SDKs (MIT licensed) but the platform itself is a hosted SaaS service. For fully self-hosted deployments, Grafana Stack, Jaeger, Zipkin, and SigNoz are better options since their entire backend is open source.
While the software is free, self-hosting requires infrastructure costs (compute, storage, networking), engineering time for setup and maintenance, and ongoing operational overhead. For Jaeger or Zipkin, expect 2-5 hours per week for a small deployment. SigNoz and Grafana Stack require more resources but offer more features.
SigNoz offers the simplest self-hosted setup with a single Docker Compose file that includes tracing, metrics, and logging. Jaeger is also straightforward for tracing-only use cases. Grafana Stack requires assembling multiple components (Tempo, Loki, Mimir, Grafana) which adds complexity.
Grafana Stack and SigNoz are designed for enterprise scale with horizontal scaling and multi-tenancy. Jaeger scales well for tracing with Cassandra or Elasticsearch backends. Zipkin is suitable for small to medium workloads but may require more tuning at scale.
