ASEAN Perspective
Opik in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Opik is one of the more complete open-source LLM observability stacks, combining tracing, evaluation, optimization and guardrails in a single self-hostable package. Independent benchmarks have cited it as notably fast for trace logging versus rivals.
Backed by Comet's experiment-tracking heritage, it is a strong fit for teams that want a free, on-prem alternative to LangSmith or Braintrust without giving up production-grade dashboards. The managed cloud tier exists for those who would rather not self-host.
