GILD verdict
Pick kcap to keep coding agents' sessions as shared team memory priced per seat, and Langfuse to trace and evaluate an LLM application you build.
For a team of 10 on monthly billing, GILD's calculation puts kcap Team at US$225 a month from the pricing page against US$29 on Langfuse Core within its included units.
Disclosure: Kurrent is a GILD event partner. GILD writes its reviews on its own. kcap records every coding agent's sessions as shared team memory, priced per seat. Langfuse traces and evaluates the LLM applications a team builds, and for Claude Code it captures full conversations through Claude Code's hooks, on Cloud plans that meter units.
Choosing between kcap and Langfuse
Choose kcap if
- Your team runs several coding agents and wants every session searchable by teammates and readable by the next agent.
- You want seat pricing, with a free local edition for one developer.
- Sessions should stay until a member or an admin deletes them.
Choose Langfuse if
- You trace and evaluate an LLM application your team builds, with LLM-as-a-Judge, human annotations or custom evaluation workflows.
- You want unlimited users on Core at US$29 a month with 100k units included.
- You want a data access window per plan and a retention policy that deletes data on Pro and Enterprise.

| Session capture | A hook in each coding agent sends the session to the workspace as it happens: prompts, the agent's replies, every tool call and its result, and the commits it made1 | For Claude Code, an integration built on Claude Code's hooks system captures full conversation interactions and sends them to Langfuse6 |
