Traceloop

LLM reliability platform with zero-setup evals and OpenTelemetry tracing.

65/100MonitorFree planFreemium

Traceloop stands out for its zero-setup evaluations and OpenTelemetry-native tracing. The free tier is generous, but scaling past 50K spans per month requires a sales call. The ServiceNow acquisition could shift priorities, but for now it's a strong open-source-based option. If you need deep workflow automation or a no-code builder, consider alternatives like Langfuse or Helicone, but for reliability-focused teams, Traceloop is a solid pick.

Skip it if

Skip Traceloop if you need a free tier larger than 50K spans per month, if you want a no-code LLM builder without tracing, or if you prefer a fully managed SaaS without on-prem options.

The 30-second take
Biggest gripe

Going past 50K spans per month requires upgrading to Enterprise (custom pricing), which involves a sales call and likely a minimum contract.

Price reality

Traceloop's free tier (50K spans/month) is generous for prototyping, unlike Langfuse's 100K events free tier. Enterprise pricing is custom, but for mid-size teams, it's comparable to competitors like Langfuse (paid tiers from $15/month) or Helicone (usage-based). If you need on-prem, Traceloop's Enterprise tier includes it, which many competitors charge extra for.

In short

Traceloop — LLM reliability platform with zero-setup evals and OpenTelemetry tracing. Best for ML/MLOps engineers debugging LLM failures in production, Product teams shipping LLM features with confidence, Engineering managers enforcing quality gates in CI/CD. Free to use.

About Traceloop

FreemiumIntermediateAPI availableWeb · API · CLI

Traceloop is an LLM reliability platform for teams shipping AI applications in production. It combines OpenTelemetry-based tracing with automated quality evaluations, turning raw logs into actionable insights. With a one-line code setup using the open-source OpenLLMetry SDK, you get live visibility into prompts, responses, and latency. Built-in checks for faithfulness, relevance, and safety run automatically on your real data, and you can define custom evaluators by annotating examples—no test writing required. Evaluations can run on every pull request or in real time, so quality drift is caught before it reaches users. Traceloop also includes a smart proxy (Hub) for routing and observability, supporting 20+ LLM providers, vector databases, and frameworks like LangChain, LlamaIndex, and CrewAI. Deployment options span cloud, on-prem, and air-gapped environments, with SOC 2 and HIPAA compliance. In March 2026, Traceloop announced it is joining ServiceNow, which may accelerate development and expand its integration ecosystem. If you're already invested in OpenTelemetry, Traceloop offers a low-friction path to LLM-specific observability and evaluations, establishing a continuous feedback loop for your LLM systems.

Behind the Verdict

Traceloop's core strength is its combination of OpenTelemetry-based tracing with built-in quality evaluations. You get a monitoring dashboard and evaluation dashboard out of the box, and you can run evaluations on every pull request to catch regressions early. The ability to train custom evaluators by annotating real examples is a standout feature—it lets you define quality on your terms, not just rely on off-the-shelf metrics. The smart proxy (Hub) simplifies routing and adds observability without code changes. However, the free tier caps at 50K spans per month with only 24 hours of data retention, which is tight for active development. Scaling past that means a sales call, and there's no mid-tier plan. The platform is built on OpenTelemetry, so if you're not using it, there's a learning curve. The ServiceNow acquisition could bring resources, but it also introduces uncertainty about product direction. Traceloop is best for ML/MLOps engineers, product teams shipping LLM features, and engineering managers who want quality gates in CI/CD. It's especially good for teams already using OpenTelemetry. If you need a fully managed SaaS without on-prem options, or if you want a no-code LLM builder, look elsewhere—but for reliability-focused teams, Traceloop is a practical choice.

Real-world workflow fit

Concrete scenarios for the personas Traceloop actually fits — and what changes day-one when you adopt it.

ML engineer at a startup

You integrate OpenLLMetry SDK with one line of code and immediately see traces in the dashboard. You enable built-in evals for faithfulness and relevance, and set up CI/CD integration to run them on every pull request.

Outcome: You catch a regression in prompt performance before merging, and the team ships with confidence.

Product manager at an enterprise

You deploy Traceloop on-prem to meet compliance. You train a custom evaluator by annotating examples of good and bad responses, and set up real-time monitoring with alerts for quality drift.

Outcome: You get a baseline of model quality and alerts when it slips, reducing user complaints and debugging time.

Engineering manager at a mid-size company

You want to enforce quality gates in CI. You use Traceloop's CI/CD integration to run evaluations and enforce thresholds before merging.

Outcome: Regressions are caught automatically, and you have a clear feedback loop for improving prompts and models.

Use Cases

  • Monitor LLM response quality in production and get alerts on drift or hallucinations.
  • Run automated evaluations on every pull request to catch regressions before merging.
  • Trace end-to-end requests across LLM calls, retrievals, and framework steps to debug failures.
  • Track token usage and cost per user or feature to optimize spending.
  • Train a custom evaluator that scores outputs according to your specific quality criteria.
  • Reproduce a production issue in your IDE by replaying captured traces as test cases.

Limitations

  • Traceloop's free tier caps at 50K spans per month with 24-hour data retention, and scaling past that requires a sales call.
  • The platform is built on OpenTelemetry, so you need to integrate the SDK or Hub to get tracing.
  • Custom evaluator training requires manual annotation of real examples.
  • On-prem deployment is enterprise-only, and air-gapped setups may need additional configuration.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Going past 50K spans per month requires upgrading to Enterprise (custom pricing), which involves a sales call and likely a minimum contract.
  • On-prem deployment and air-gapped options are only available on the Enterprise tier, so smaller teams can't use them without upgrading.
  • The free tier's 24-hour data retention means you lose historical data quickly unless you upgrade to Enterprise with custom retention.
  • Custom evaluator training requires manual annotation of real examples, which takes engineering time and may need ongoing maintenance.
  • While OpenLLMetry is free and open-source, connecting to Traceloop's platform for full monitoring and evaluation features requires a paid plan beyond the free tier.

Where the pricing makes sense

The company stage and team size where Traceloop's pricing actually pencils out — and where peers do it cheaper.

Traceloop's free tier (50K spans/month) is generous for prototyping, unlike Langfuse's 100K events free tier. Enterprise pricing is custom, but for mid-size teams, it's comparable to competitors like Langfuse (paid tiers from $15/month) or Helicone (usage-based). If you need on-prem, Traceloop's Enterprise tier includes it, which many competitors charge extra for.

Setup time & first value

How long it actually takes to get something useful out of Traceloop — broken out by persona, not the marketing-page minute.

For OpenLLMetry SDK, you can start seeing traces in under 10 minutes with one line of code. Hub setup may take 30 minutes to configure routing. Custom evaluators require annotation time—budget a few hours to train effectively.

Switching to or from Traceloop

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • From Langfuse: Export traces from Langfuse and import into Traceloop to maintain history; use OpenLLMetry SDK to instrument your app.
  • From custom logging: Replace your manual logging with OpenLLMetry SDK to automatically capture spans and traces.
  • From Helicone: Similar tracing features; switch by updating your endpoint to Traceloop Hub or adding the SDK.
Migrating out
  • To Langfuse: Use the OpenTelemetry exporter to send traces to Langfuse's endpoint.
  • To Datadog: If using OpenTelemetry, you can export traces to Datadog's APM.
  • To self-built: Since OpenLLMetry is open-source, you can fork it and connect to any OTLP-compatible backend.
