概览

Chroma 是一个专为 AI 应用打造的开源数据库，专注于存储、索引和查询向量嵌入及其元数据。它让开发者能快速为基于 LLM 的应用添加语义搜索、检索增强生成和记忆功能，无需拼装一堆单独组件。该项目附带 Python 与 JavaScript 客户端，提供简易的集合与查询 API，并集成了如 LangChain 和 LlamaIndex 等流行框架。它可在进程内运行进行原型开发，也可作为服务器处理生产工作负载，并为不想自托管的团队提供托管云选项。由于其开源且轻量，Chroma经常被那些想要构建检索管道和 AI 功能，并需要一个透明、可自定义基础的开发者所选用。

主要功能

支持元数据过滤的向量存储
Python和JavaScript SDKs
嵌入或客户端-服务器模式
内置嵌入函数支持
LangChain和LlamaIndex集成
可选的托管云主机

使用场景

LLM应用的检索增强生成

在Chroma中存储文档嵌入，并在推理时查询它们，以将LLM响应置于相关上下文中，减少聊天机器人和助手中的幻觉。

自定义内容的语义搜索

将产品目录、文档或知识库索引为带有元数据过滤器的向量，以提供基于意义的搜索结果，而不是关键词匹配。

AI代理的长期记忆

使用Chroma作为持久记忆存储，以便LLM代理可以回忆过去的对话、用户偏好和跨会话的先前操作。

AI特性的本地原型设计

在Python或JavaScript项目中运行嵌入式Chroma，以快速原型设计带有LangChain或LlamaIndex的RAG管道，然后部署到服务器或托管云。

Years in this space

I've evaluated a lot of these over the years. What stands out here is embedded or client-server modes — handled better than most — and free and open source. Worth the time if this is your use case.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on embedded or client-server modes, and simple, developer-friendly API caught me off guard. still, I'd recommend giving it a real trial.

Solid for our team

We rolled this out across the team last quarter and simple, developer-friendly API. Built-in embedding function support fits neatly into how we already work, and langChain and LlamaIndex integrations removed a step we used to do by hand. Newer project, still maturing, which is the main caveat, but it has held up under daily use.

Years in this space

I've evaluated a lot of these over the years. What stands out here is built-in embedding function support — handled better than most — and works locally or as a server. Newer project, still maturing is my one real gripe. Worth the time if this is your use case.

问答

Can I export my data if I decide to leave?

Chroma is an open-source product and egressing your data is easy.

Asked by Naomi Suzuki · Mar 6, 2026

What happens if I exceed my plan's usage limits?

There are 2 kinds of usage-limits. Customer set usage limits and Chroma set usage limits. Both result in a pausing of the service until the limit is changed.

Asked by Devin Walker · Feb 13, 2026

Can I change my plan in the middle of a billing cycle?

Your plan change will be pro-rated to the calendar month. This applies to downgrades and upgrades.

Asked by Nadia Petrova · Feb 8, 2026

What payment methods do you accept?

Currently Chroma accepts credit card for Starter and Team plans. Enterprise plans have configurable billing methods.

Asked by Celia Ramirez · Dec 25, 2025

Do unused credits rollover to the next month?

Yes, in most cases your credits do not expire. The $100 of included usage in the Team plan does not rollover.
