OpenLIT is free and broad on paper, with OpenTelemetry export and GPU monitoring among its draws. The catch is self-hosting, and hosted pricing is not published on the vendor's site. Reddit discussions also point to gaps around logs and documentation. If you’re switching, choose based on what you need next: Helicone for gateway and tracing, HoneyHive for evaluation, Coval for voice agents, or Agenta for building AI coworkers—not as a direct observability replacement.
01Why people leave OpenLIT
Logs may be missing
In one Reddit thread, OpenLIT’s maintainer said logs were not supported at the time and were on the roadmap.
Telemetry details felt unclear
A Reddit user asked for a documented list of collected variables. The maintainer said that documentation was missing; metrics included requests, tokens, and cost.
GPU debugging isn’t guaranteed
In a Reddit discussion about a GPU going offline, a commenter said OpenLIT would not yet help if the user was self-hosting the LLM.
02The alternatives, ranked by fit
- Gateway and tracing
HeliconeHeliconeHelicone is the closest fit here if you want gateway functionality alongside LLM tracing, rather than choosing a tool aimed mainly at voice testing or agent building. Its listed strengths include prompt and agent inspection. The pricing page says it has a free plan and starts at $79, but flags pricing uncertainty and reports a slowdown in development—worth weighing before you move production traffic.
Trade-off: Pricing is uncertain, and the listing reports slower development.
6.2/10from
$79/mofree plan - Agent evaluation
HoneyHiveHoneyHiveChoose HoneyHive if your main reason for leaving is to evaluate AI agents before release or monitor traces and quality. Those are its stated strengths, and a free plan gives small teams a starting point. The pricing page does not publish a starting price; it warns that the event cap needs checking and Enterprise pricing requires a quote.
Trade-off: Check the event cap; Enterprise pricing requires a quote.
7.2/10from
Freefree plan - Voice agent QA
CovalCovalCoval fits teams whose observability problem is specifically testing voice agents before launch or tracking their quality in production. The pricing page also positions it for comparing voice AI vendors. It starts at $80, but the listing warns that simulation limits deserve scrutiny. It is a narrower move than replacing a general LLM observability tool.
Trade-off: It focuses on voice AI, and simulation limits need scrutiny.
6.5/10from
$80/mo - AI coworker building
AgentaAgentaAgenta is for teams building and running AI coworkers, including Slack or Telegram agents and scheduled or triggered tasks. The pricing page identifies it as MIT-licensed and suitable for self-hosters, with a free plan and pricing from $29. Pick it if your project is agent building; the listing specifically cautions against treating it as a replacement for an AI observability stack.
Trade-off: It is not a direct replacement for an AI observability stack.

Questions people ask
How much does OpenLIT cost?
The pricing page describes OpenLIT as having a free plan, with a starting price of n/a. Hosted pricing is not published in the published material. That makes a direct price comparison difficult: confirm whether you need to self-host and ask OpenLIT for current hosted pricing before switching.
Which OpenLIT alternative is closest for observability?
Helicone is the closest match among these options if you need gateway functionality and tracing together; its listed capabilities also include prompt and agent inspection. HoneyHive is a better fit for agent evaluation and trace or quality monitoring. Neither listing establishes identical OpenTelemetry or GPU-monitoring support to OpenLIT.
Can these tools replace OpenLIT for GPU monitoring?
The published information identifies GPU monitoring as an OpenLIT strength, but does not list GPU monitoring for these four alternatives. Helicone, HoneyHive, Coval, and Agenta are described for other needs. Check each product’s current documentation before switching if GPU metrics are required.
