Who it suits

  • Small businesses that want tracing set up with no upfront spend
  • Enterprise teams that already run their own infrastructure and need a wide integration list
  • Developers who prefer documentation and community over live support

Who should look elsewhere

  • Teams wanting phone or chat support, since support runs on help centre and community only
  • Buyers who need a published tier ladder, as only a free plan shows in free plan
  • Anyone shopping at the €10.33 entry budget, below the $29 price point

The company behind it

Langfuse is operated by Langfuse GmbH, registered in Germany, and was founded in 2022. It is listed as serving both small business and enterprise. Support is delivered through help centre and community, so answers to questions come from a help centre and from other users rather than from a staffed channel. There is no named account manager or phone line in the published support options.

How Langfuse compares

Frequently asked questions

How much does Langfuse cost to start?+

Entry pricing is listed at $29. That sits above the €19.65 median for automation tools, so readers shopping purely on entry cost will find cheaper options. The published pricing page does not split introductory from renewal pricing, so the figure should be read as the starting point.

Is there a free plan?+

Free plan is yes. The free plan listing includes a free plan, and 50k units/month on free Hobby plan describes the monthly allowance that comes with it. That means a small team can run at no cost until usage outgrows the free tier.

What are the usage limits on the free tier?+

The stated limit is 50k units/month on free Hobby plan. Usage above that allowance is what pushes a team toward a paid tier. Compare that ceiling with your own volume before committing, since the free plan entry is the only published model.

How many integrations does Langfuse offer?+

The integrations directory lists 100 integrations. A count that broad is the main argument for teams running a mixed stack, because the tracing layer can sit alongside tools already in use. It is the strongest feature signal on the pricing page.

What support can I get as a customer?+

Support runs through help centre and community, meaning a help centre and a community. No phone or live chat option is listed, so time-sensitive issues may need patience. For teams that require a staffed response, this is the main gap.

Who is Langfuse built for?+

The stated audience is small business and enterprise, so it is aimed at both small businesses and larger organisations. Teams willing to run their own setup get the most from the integration list. Beginners wanting a guided install may find the self-serve model slower.

Where is the company based?+

The legal entity is Langfuse GmbH, headquartered in Germany, and founded in 2022. Contracts and invoices therefore sit with a German company, which can matter for procurement checks in some regions.

How does the price compare with other automation tools?+

At $29, Langfuse is cheaper than the €34.20 upper quartile but pricier than the €10.33 lower quartile. Its rank on price from is 192 of 307 brands compared. Cheaper entry exists elsewhere in the category.
