Most buyers should pick OpenLIT.
Choose OpenLIT if you want an Apache 2.0, self-hosted observability stack with OpenTelemetry export and no per-trace fee. Choose HoneyHive if production evaluations, offline experiments, and step-by-step agent replay matter more—and its 10,000-event, five-user Developer plan fits. Both list a $0 option, but neither publishes paid monthly or annual rates. HoneyHive publishes its free caps; OpenLIT's hosted Cloud pricing is still coming, while Enterprise is contact-us.

02Pricing compared
Both products list a $0 option, but only HoneyHive publishes free-plan caps. OpenLIT’s OSS plan is free under Apache 2.0 for self-hosting, with unlimited self-hosted usage and no per-trace fee. Its Enterprise plan is contact-us, and Cloud pricing is still to be shared at launch. Paid monthly and annual rates are not published.
HoneyHive’s Developer plan is $0 per month and includes 10,000 events monthly, up to five users, one workspace, 30-day data retention, and 1,000 requests per minute. Enterprise pricing is custom; the plan lists custom usage limits, users, workspaces, and retention. Neither product publishes paid monthly or annual rates. Compare OpenLIT’s free usage with HoneyHive’s event cap, but factor in self-hosting before treating OpenLIT as the cheaper switch.
03Features and depth
OpenLIT combines LLM tracing, evaluations, prompt management, agent monitoring, an API key vault, and GPU monitoring. Its tracing covers LLM calls, tools, and retrieval, with filters for user, session, cost, latency, or metadata. Evaluations can use LLM judges, heuristics, or human review on production traffic or experiments. OpenTelemetry support lets teams export telemetry to other OpenTelemetry backends.
HoneyHive’s feature set puts more detail around evaluation workflows. It can replay runs step by step, including prompts, tool calls, decisions, and handoffs; compare agent versions on the same dataset; and score outputs, tools, interactions, or trajectories with LLM judges, custom code, or composite evaluators. It also lists production alerts and drift detection, plus prompt testing and CI evaluations to gate releases. Both products offer prompt management and evaluation. OpenLIT stands out for its stated GPU monitoring and OpenTelemetry approach; HoneyHive lists offline experiments, replay, and alerting in more detail.
04Ease of use and learning curve
The clearest practical difference is deployment. OpenLIT’s $0 OSS plan is self-hosted, so teams choosing it need to run that deployment themselves; its hosted Cloud option is listed as coming soon, with pricing not yet published. The published review rates its ease of use 6.2 out of 10.
HoneyHive offers a Developer plan with published limits, so teams can judge whether 10,000 monthly events and five users are enough before considering Enterprise. Enterprise can include optional self-hosting, hybrid, or single-tenant deployment. Its published ease-of-use score is 7 out of 10. Those scores are not a substitute for checking fit: your deployment preference and expected event volume matter more.
Questions people ask
Which is cheaper, OpenLIT or HoneyHive?
Both list a free option. OpenLIT OSS has unlimited self-hosted usage and no per-trace fee, but self-hosting costs are not published. HoneyHive Developer is free with a 10,000-event monthly cap and other limits. Neither publishes paid monthly or annual rates, so paid-plan cost cannot be compared from the listed prices.
Can we self-host either product?
OpenLIT’s OSS plan is explicitly self-hosted under Apache 2.0. HoneyHive lists optional self-hosting, hybrid, or single-tenant deployment under Enterprise. The available pricing information does not list those deployment options for its free Developer plan.
Does OpenLIT have a usage cap on its free plan?
OpenLIT lists unlimited self-hosted usage and no per-trace fee on its $0 OSS plan. That applies to the self-hosted OSS offering; hosted Cloud pricing is not published and is described as coming soon.
Which product is stronger for AI agent evaluations?
HoneyHive lists offline experiments, dataset comparisons, step-by-step run replay, and evaluators for outputs, tools, interactions, and trajectories. OpenLIT also supports evaluations, using LLM judges, heuristics, or human review on production traffic or experiments. Choose based on which workflow you need.
