vLLM Alternatives
Tools that serve open models behind an API for many users, like vLLM. On GitHub, vLLM describes itself as: “A high-throughput and memory-efficient inference and serving engine for LLMs”. Below are the 5 other open-source tools we track for the same job, ranked by live maintenance data from GitHub.
Short answer: Ranked by our health score from public GitHub data on 18 October 2026, the most actively maintained alternatives to vLLM are SGLang (100), LocalAI (100) and TensorRT-LLM (97). vLLM itself is still actively maintained (health score 100), so switching is a choice, not a necessity.

vLLM alternatives: common questions
What is the best alternative to vLLM?
No single tool is best for every project. By maintenance signals on 18 October 2026, the highest-ranked actively maintained alternative is SGLang (health score 100, 4,904 commits in the last 91 days). Compare features and the licence before you switch; we have not tested these tools ourselves.
Is vLLM still maintained?
Yes. As of 18 October 2026, vLLM received 4,411 commits in the last 91 days and its latest commit is from 18 October 2026, and no maintenance notice was found. Its health score is 100 out of 100.
Which vLLM alternatives have a permissive licence?
Among the actively maintained alternatives, these use a permissive licence according to GitHub: SGLang (Apache-2.0), LocalAI (MIT), LMDeploy (Apache-2.0). Always read the licence file itself before commercial use.
How are these alternatives chosen and ranked?
We list the tools we track that do the same job as vLLM (LLM inference servers). They are ranked by maintenance status first (active, slowing down, stopped) and by our health score second. The score combines commit activity, the trend against last year, the date of the last commit, the last release and merged pull requests, all from GitHub. It does not measure features, speed, quality or security.
How this works: we group tools by the job they do and rank the ones we track with public GitHub data (commits on the default branch, releases, merged pull requests, archived flag, and maintenance notices in the README), refreshed automatically. We have not tested these tools ourselves, so the ranking says how well each project is maintained, not which one has the features you need.
