Langfuse Pricing (2026)
Langfuse has a free Hobby plan, and paid plans start at $29/mo.
It's a platform fee plus metered usage: you pay a flat monthly base per tier, then $8 per 100k units (traces, observations, scores) on top, with volume discounts as you scale. The value metric is really event volume, not seats, which fits how LLM apps actually generate load.

AI Pricing Analysis
Pricing Model
It's a platform fee plus metered usage: you pay a flat monthly base per tier, then $8 per 100k units (traces, observations, scores) on top, with volume discounts as you scale. The value metric is really event volume, not seats, which fits how LLM apps actually generate load.
Tier Strategy
Hobby is for tinkerers and side projects, Core ($29) is the no-brainer for a small team shipping to production, and Pro ($199) is where real teams land once they need more retention and collaboration. The Enterprise jump to $2,499 is a cliff aimed at procurement-driven orgs that need yearly commits, custom volume pricing, and compliance-grade controls.
Competitive Positioning
Langfuse plays the developer-friendly value card in the LLM observability space, with a generous free tier, a cheap $29 entry point, and a self-host escape hatch that undercuts closed-source rivals on trust and cost. Startup, EDU, and OSS discounts show they're courting the builder community first and treating enterprise as the follow-on revenue.
Growth Lever
Expansion is mostly usage-driven, since every new LLM feature or user your customers ship adds traces and bumps the overage bill. The sneaky upsell is the $300 Pro Teams add-on: SSO, SSO enforcement, and fine-grained RBAC are classic security gates that force a mid-size team to pay up once IT gets involved, even if their usage hasn't grown.
