langchain4j
LangChain4j is an idiomatic, open-source Java library for building LLM-powered applications on the JVM. It offers a unified API over popular LLM providers and vector stores, and makes implementing tool calling (including MCP support), agents and RAG easy. It integrates seamlessly with enterprise Java frameworks like Quarkus and Spring Boot.
Growth we measured

- Ranked #728 by stars among the 2,497 repos we snapshot, using the latest star count we recorded for each.
- Rank movement: #237 on 2026-09-06 (13,024 stars) → #240 today — down 3 places among the 672 repos we snapshotted in both windows.
- Its 7-day pace is faster than 57% of the 1,252 repos where we can currently measure one (#534).
How this is measured. whatstrending.ai stores its own daily star and fork snapshot for every repo in its trending index. Every figure above is a delta between two of those stored rows — 59 snapshots for langchain4j/langchain4j between 2026-08-09 and 2026-10-06. Our history starts 2026-06-19; we hold nothing from before that date. Nothing here is estimated, interpolated or back-filled, and days without a snapshot are simply not plotted.
Add the Trending AI Repo badge to your README
langchain4j/langchain4j is in the whatstrending.ai tracked index, so this badge already resolves. It is free, needs no account, and updates itself: the rank is recomputed from our stored daily snapshots and the image is re-fetched a few times a day. Clicking it lands on this page, which shows the star history we measured.
