Is anyone using langchain?

Dependents: no admitted own package.

Weekly dependents
PartitionDirect dependentsWeekly pointsMethod
no partitionno readingno readingm5 own packages

deps.dev weekly direct dependents of the system's own packages. A package counts when it is declared in the system's own tree, published under that name and not attributed by deps.dev to another repository. Partition dates can repeat across snapshots. Package linkage is not uniformly verified: packages with no repository metadata (no_link) are unverified and remain admitted.

Daily package dependents (unscored): 3,158; captured 2026-11-06; package: pypi/langchain. deps.dev REST count for one identity-verified pinned package, captured daily and never scored. Its package scope differs from the weekly package union; neither value replaces the other. 149,138 GitHub stars, recorded, not scored.
