| Deployment | The platform can be self-hosted using Docker Compose or Kubernetes Helm and accepts OpenTelemetry data through OTLP. | Traceloop says it supports cloud, on-premises, air-gapped, and other restricted deployments, including Kubernetes environments. |
| Documentation depth | The documentation includes provider-specific SDK guides, observability pages, controller deployment material, CLI configuration and an indexed documentation file. | Documentation covers SDK setup, tracing, evaluators, experiments, monitoring, prompt management, API keys, projects, integrations and self-hosting. |
| Evaluations | OpenLIT includes built-in evaluations, programmatic evaluations and LLM-as-a-judge workflows that can run locally or in CI. | Traceloop describes built-in quality checks for faithfulness, relevance, and safety, and says users can train custom evaluators on their data. |
| Integrations | The home page advertises more than 56 integrations spanning LLMs, agent frameworks, vector databases and GPUs. | OpenLLMetry supports providers including OpenAI, Anthropic, Bedrock, Gemini, Cohere, Mistral, Ollama and Vertex AI. |
| Prompt management | Prompt Hub provides prompt versioning, dynamic variables, API retrieval and AI-assisted prompt improvement. | The platform includes prompt management and a prompt registry for storing and fetching prompt configurations. |
| Public API | The sandbox exposes an OpenAPI description and API-key scopes covering ingestion, telemetry, prompts, vault, evaluations, chat, controller and database configuration. | Traceloop exposes APIs authenticated with bearer API keys that can both send traces and query data. |
| Rating on G2 | 5.0 out of 5 from 1 review. | 5 out of 5 from 2 reviews. |
| Self-hosting | Docker Compose runs the UI on port 3000, OTLP receivers on ports 4317 and 4318, and ClickHouse for traces, metrics and logs; Kubernetes Helm deployment is also documented. | Full-platform self-hosting uses Kubernetes with ClickHouse, Kafka, PostgreSQL and S3-compatible storage, including air-gapped deployments. |
| Support | The OSS plan includes community support on GitHub. | The Enterprise plan includes dedicated Slack support, according to the pricing page. |
| Tracing | LLM tracing can capture calls, tools, and retrievals, with filters for user, session, cost, latency, and metadata. | One-line instrumentation provides visibility into prompts, responses, latency and request execution traces. |
| What it does | OpenLIT is an OpenTelemetry-native platform for tracing, evaluating, guarding and improving AI agents and coding agents. | Traceloop monitors, evaluates, debugs and tests LLM applications and agents in production. |

In their own words
OpenLIT
OpenLIT is an open-source platform for tracing and evaluating LLM activity, managing prompts, and tracking costs. Built on OpenTelemetry, it can capture model calls, tool use, and retrievals, with filters for user, session, cost, latency, and metadata. Evaluations can use an LLM judge, heuristics, or human review on production traffic or experiments. Prompt Hub provides versioning, dynamic variables, API retrieval, unlimited prompt fetching, and AI-assisted improvement. OpenGround supports side-by-side model comparisons for latency, tokens, and cost, including comparisons using a user’s own key. Coding agent monitoring covers sessions, costs, tokens, repository activity, and code impact. The site lists more than 56 integrations across LLMs, agent frameworks, vector databases, and GPUs. OpenLIT accepts OTLP data and can be self-hosted with Docker Compose or Kubernetes Helm. Its Apache 2.0 license and site description note that self-hosting keeps prompts, traces, and secrets in the user’s environment. The OSS plan costs nothing and includes unlimited self-hosted usage, users, projects, and environments.
