[aikit](https://kaito-project.github.io/aikit/) reports 533 GitHub stars, 57 forks, and 41 open issues, last pushed Jul 11, 2026. [langserve](https://github.com/langchain-ai/langserve) has 2.3k stars, 271 forks, and 139 open issues, last pushed May 5, 2026. Figures are from public GitHub metadata via [aikit's repository](https://github.com/kaito-project/aikit) and [langserve's repository](https://github.com/langchain-ai/langserve). | | [aikit](/tools/kaito-project-aikit.md) | [langserve](/tools/langchain-ai-langserve.md) | | --- | --- | --- | | Tagline | Fine-tune, build, and deploy open-source LLMs easily! | LangServe 🦜️🏓 | | Stars | 533 | 2,330 | | Forks | 57 | 271 | | Open issues | 41 | 139 | | Language | Go | JavaScript | | Adopt for | Aikit is a toolkit designed for fine-tuning, building and deploying large language models (LLMs) with an emphasis on open-source technologies. | LangServe offers tools to deploy and serve models using LangChain with FastAPI. | | Persona | - | - | | Runtime | - | - | | License | MIT | Other | | Categories | LLM Frameworks, Model Training, Inference & Serving | Inference & Serving | ## Trust and health _Sourced signals - not a safety guarantee.
