blog: LangSmith TCO teardown + Claude Code vs Cursor with OTel#8
Merged
Conversation
Two competitive-landscape posts that name names. - LangSmith TCO teardown (publishDate 2026-05-21): pricing audit grounded in CheckThat.ai's 10.7x-sticker finding, anchored against the 2026-05-13 LangSmith Engine / SmithDB launches. Includes a honest decision tree for when LangSmith is actually the right tool. - Watching Claude Code with OTel (publishDate 2026-05-25): comparison of Claude Code (real OTel pipe), Cursor (no OTel), and /cost (per-session, read-only). Explains what the OTel wire actually emits and which failure modes none of the built-in views catch. Final post of the May launch sprint, isolated by 4 days from the preceding post to give earlier posts time to accumulate engagement signal before the last one drops.
