Langfuse Cuts Data Retention From Unlimited to 3 Years on Pro Plans
What happened
Between the Dec 29, 2025 and Mar 30, 2026 captures of Langfuse's pricing page, Pulse recorded 2 changes: Enterprise contracts section updated: 'Custom with Yearly Commitment' replaced by 'Talk to Sales'; Custom Terms & DPA removed from Yearly Commitment add-on bullet points; Pro and Enterprise plan data access reduced from Unlimited to 3 years. Previously both plans offered unlimited historical data access. Pulse files it as a packaging change (positioning, limit lowered). Pulse's latest capture (Nov 9, 2026) lists Core at $29, Pro at $199, Enterprise at $2,499 and Teams at $300.
This quarterly roll-up includes 3 changes Pulse first recorded in a shorter period: "Langfuse launches non-profit discount with $199 monthly credits" (week of Mar 23, 2026, saved Mar 30, 2026), "Langfuse Drops Custom Enterprise Terms, Pushes Buyers to Sales" (week of Mar 2, 2026, saved Mar 9, 2026) and "Langfuse cuts data retention from unlimited to 3 years" (week of Feb 9, 2026, saved Feb 16, 2026). They are the same changes, not new ones.
