LangSmith plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Developer | Free | 2 | Entry tier |
| Plus | $39/month | 3 | +$39/month, 3 more features |
| Enterprise | On request | 3 | Priced on request |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

Before you pay for LangSmith
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 3 tiers between Free and On request, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
LangSmith runs on not recorded. The full record is on the LangSmith review, and the rest of the category is under best software development tools.
